## [Unreleased]

## [0.27.0] - 2026-05-23

### Added
- **JFM→ADF Auto-Conversion for Rich-Text Custom Fields** ([#866](https://github.com/rust-works/omni-dev/issues/866)): String values supplied for rich-text/textarea JIRA custom fields are now auto-converted from JFM markdown to ADF — both via the MCP `jira_write` `fields` escape hatch and via the CLI's `--set-field NAME=VALUE`. Callers no longer need to hand-craft `{"version":1,"type":"doc",…}` payloads for fields like Acceptance Criteria (`customfield_19300`); a plain `"- bullet\n- bullet"` is converted using the same pipeline that already serves `content`/description and body sections. An empty string (or YAML null on the CLI side) clears the field. JSON object values are passed through unchanged, preserving the raw-ADF path for callers who need it. Implemented as a new `convert_textarea_string_values` helper in `src/atlassian/custom_fields.rs` (shared with a relaxed `resolve_custom_fields` that now accepts string scalars for rich-text fields) and wired into `run_jira_write` in `src/mcp/jira_core_tools.rs` with a lazy prefilter — editmeta is only fetched when at least one `fields` value is a string. Per-issue editmeta is cached via a new `editmeta` slot on `CatalogueCache` (`src/mcp/catalogue_cache.rs`) with a 60-second TTL (separate `EDITMETA_TTL` constant) and the same single-flight semantics as the other catalogue slots. Metadata-lookup failures fall back to passthrough — the API surfaces its own error rather than failing the write. Covered by 7 unit tests on the conversion helper, 7 wiremock integration tests on `run_jira_write` (string→ADF, object passthrough, empty→null, non-textarea passthrough, editmeta-failure passthrough, invalid-nesting short-circuit, unknown-field passthrough), 3 CLI tests on `--set-field` for textareas, and 5 editmeta-cache unit tests.
- **Actionable Error for JIRA ADF-Required Fields** ([#867](https://github.com/rust-works/omni-dev/issues/867)): When `jira_write` submits a plain string to a JIRA rich-text custom field, JIRA returns HTTP 400 with `errors.<field_id>: "Operation value must be an Atlassian Document (see the Atlassian Document Format)"`. The error is now enriched with the offending field ID(s), a `To fix:` hint pointing at JFM markdown and the `omni-dev://specs/jfm` resource, and the verbatim original API message — instead of being relayed as an opaque body. Implemented via a new `jira_write_error` helper in `src/atlassian/client.rs` (paralleling `confluence_write_error` in `src/atlassian/confluence_api.rs`) and a new `AtlassianError::JiraAdfFieldRequired { fields, original_message, body }` variant in `src/atlassian/error.rs`. Multi-field 400s are joined into a single header line. Non-ADF 400s and all other status codes fall back to the existing `ApiRequestFailed` format. Scoped to the JIRA update path (`update_issue_with_custom_fields`); the create path is intentionally out of scope. Covered by three Display unit tests in `error.rs` and two integration tests (`run_jira_write_enriches_adf_required_error`, `run_jira_write_falls_back_for_non_adf_400`) in `src/mcp/jira_core_tools.rs`.
- **Confluence Inline (Anchored) Comments** ([#830](https://github.com/rust-works/omni-dev/issues/830)): omni-dev's Confluence comment surface now distinguishes footer comments (page-level) from inline comments (anchored to a text selection), closing the gap with the official Atlassian MCP server. Three additions: (1) new `omni-dev atlassian confluence comment add-inline <PAGE-ID> [FILE] --anchor-text "..." [--match-index N]` CLI subcommand and matching `confluence_comment_add_inline` MCP tool create inline comments by posting to `/wiki/api/v2/inline-comments` with the `inlineCommentProperties` payload Confluence requires (`textSelection`, `textSelectionMatchCount`, `textSelectionMatchIndex`); the index/count are resolved automatically by fetching the page via the existing `get_content` and counting occurrences of `--anchor-text` in the body (flattened to plain text via the new `adf_to_plain_text` helper in `src/atlassian/convert.rs`), with explicit errors for "not found", "ambiguous (specify --match-index 1..=N)", and out-of-range overrides. (2) `confluence comment list` (CLI) and `confluence_comment_list` (MCP) gain a `--kind {footer,inline,all}` filter defaulting to `all`, which issues both `/footer-comments` and `/inline-comments` v2 GETs and merges the results sorted by creation time. (3) New `omni-dev atlassian confluence comment replies <COMMENT-ID> --kind {footer,inline}` CLI subcommand and `confluence_comment_replies` MCP tool fetch a comment's reply thread via `GET /wiki/api/v2/{footer|inline}-comments/{id}/children` — the caller must commit to a kind because Confluence stores replies on kind-specific endpoints. `ConfluenceComment` gains a `kind: CommentKind` field (serialised as lower-case `"footer"` / `"inline"`) so a merged listing identifies each row; the table printer adds the kind to each comment's header line. Footer behaviour is unchanged — `confluence comment add` still posts a footer comment, the v2 footer endpoints still back it, and existing scripts that never pass `--kind` to `list` will see inline comments included by default (the intentional behaviour change). Implemented across `src/atlassian/confluence_api.rs` (new `CommentKind` enum, `InlineAnchor` struct, `get_page_inline_comments`, `get_comment_replies`, `add_inline_page_comment`, `resolve_anchor`, refactored pagination into a shared `fetch_comments_paginated` helper), `src/atlassian/convert.rs` (`adf_to_plain_text`), `src/cli/atlassian/confluence/comment.rs` (new `AddInlineCommand`, `RepliesCommand`, shared `parse_comment_input` helper), and `src/mcp/confluence_tools.rs` (extended list params, new add-inline / replies tool handlers, registration). Covered by anchor-resolution unit tests (0/1/N-match branches, `--match-index` bounds), wiremock integration tests for each new HTTP path (`POST /inline-comments`, `GET /{kind}-comments/{id}/children`, `list --kind all` issuing both GETs), and the registration test in `tool_router_registers_all_confluence_tools`.
- **`confluence space pages` Command + `confluence_space_pages` MCP Tool** ([#829](https://github.com/rust-works/omni-dev/issues/829)): New `omni-dev atlassian confluence space pages <KEY>` CLI subcommand and matching `confluence_space_pages` MCP tool enumerate pages within a Confluence space against `GET /wiki/api/v2/spaces/{id}/pages`. The space key is resolved to a space ID via the existing `resolve_space_id` helper, so callers pass the human-readable key (e.g. `ENG`) rather than an opaque numeric ID. Optional `--status` (common values: `current`, `archived`, `draft`, `trashed`) and `--sort` (common values: `id`, `-id`, `title`, `-title`, `created-date`, `-created-date`, `modified-date`, `-modified-date`) are passed through to the v2 API verbatim — no client-side allow-list, matching the `confluence_space_list` philosophy. Output records are summary-only — `id`, `title`, `status`, `parentId`, `authorId`, `createdAt` — with no page body, so listings of large spaces stay bounded in size. Pagination is explicitly cursor-driven (`--cursor` / `--limit`, default 25): the MCP tool returns a `next_cursor` callers thread back to fetch the next page, mirroring `list_spaces` rather than the auto-drained pattern in `get_space_root_pages`, because spaces with thousands of pages must not buffer entirely in memory on the MCP path. The `body-format` filter suggested in the issue is intentionally omitted — we never emit a body, so accepting it would only waste server bytes. Pairs with #828: agents can now walk from "what spaces exist?" → "what pages are in this space?" without prior knowledge of keys or IDs.
- **`confluence space list` Command + `confluence_space_list` MCP Tool** ([#828](https://github.com/rust-works/omni-dev/issues/828)): New `omni-dev atlassian confluence space list` CLI subcommand and matching `confluence_space_list` MCP tool list Confluence spaces against `GET /wiki/api/v2/spaces`. Filters `--keys <K1,K2>` (comma-separated), `--type <TYPE>`, and `--status <STATUS>` combine as AND on the wire; `--cursor` + `--limit` (default 25) page explicitly — the MCP tool returns a `next_cursor` callers pass back to fetch the next page so large space inventories never have to buffer in memory. Output fields are `id`, `key`, `name`, `type`, `status`, `homepageId`. `--type` / `--status` are passed through verbatim rather than restricted to a clap enum; Atlassian's `SpaceTypeEnum` includes template-derived values (`onboarding`, `xflow_sample_space`, `system`, `app`, …) that extend the four documented types, so a strict client-side allow-list would silently drift from reality. Invalid values surface as a clear `400 INVALID_REQUEST_PARAMETER` from Atlassian listing the current accepted set. Internally, the existing `resolve_space_id` helper was refactored to delegate to the new `list_spaces` method against the same endpoint, removing the duplicated query-building path.
- **`voice enroll` Subcommand** ([#805](https://github.com/rust-works/omni-dev/issues/805)): New CLI command at `src/cli/voice/enroll.rs` captures a microphone sample, computes a wespeaker speaker embedding, and persists it to `~/.omni-dev/voice/speakers/<name>.json`. Reuses `voice::capture::run_capture` in-process exactly as `voice capture` does — no shell-out, no duplicated pipeline. `--name <name>` chooses the JSON filename stem (default `default`); `--idle-after <secs>` stops on trailing silence (default 2 s); `--max-secs <secs>` enforces a hard upper bound (default 30 s, `0` disables); `--device <name>` selects the audio input; `--speaker-model <path>` overrides the wespeaker ONNX location; `--force` overwrites an existing enrolment. The deadline cap is enforced by a background watchdog thread that flips the same stop signal Ctrl-C uses, so capture terminates on the first of: idle silence, deadline reached, or user interrupt. The captured WAV is staged at `~/.omni-dev/voice/captures/.enroll-<UTC-timestamp>.wav` and deleted on success. The persisted `EnrolledSpeaker` JSON shape (`name`, `model`, `dim`, `vector`, `samples_used`, `enrolled_at`) matches the original #805 spec and is forward-compatible with extra fields via serde defaults. Covered by 9 unit tests for clap parsing, the install-hint error path, and WAV-format validation; the end-to-end embedding path is validated by the `#[ignore]`-gated `voice_enroll_speaker_test`.
- **`voice transcribe --speaker <name>` Filter** ([#805](https://github.com/rust-works/omni-dev/issues/805)): `omni-dev voice transcribe` now accepts `--speaker <name>` plus `--threshold <f32>` (default `0.5` — calibrated against `tests/fixtures/voice/two_speakers.wav` where within-speaker mean cosine is ≈ 0.91 and cross-speaker mean ≈ 0.07, leaving ~0.4 margin on both sides) and `--speaker-model <path>`. When `--speaker` is set, the transcribe command loads the enrolled embedding from `~/.omni-dev/voice/speakers/<name>.json`, re-reads the source WAV in parallel with the transcriber, and for each `Final` event embeds the corresponding PCM window via `WespeakerEmbedder` and drops the event when cosine similarity to the enrolled vector falls below the threshold. Surviving events are tagged with `speaker: Some(name)`. Windows shorter than 0.5 s (the minimum for stable cepstral-mean normalisation) are dropped conservatively rather than risk false positives. `Partial` and `Endpoint` events pass through untouched; the `Transcriber` trait is **not** extended — the filter is a separate composable layer over the existing event stream so future backends with native diarisation can bypass it. Implementation in `src/cli/voice/transcribe.rs::SpeakerFilter` (~140 LOC).
- **`voice install-model --variant <variant>` Flag** ([#805](https://github.com/rust-works/omni-dev/issues/805)): The install-model subcommand now accepts `--variant {whisper-tiny.en, speaker-wespeaker-en}` (default `whisper-tiny.en` for backwards compatibility — bare `voice install-model` continues to install the ASR model). Selecting `speaker-wespeaker-en` downloads [`wespeaker_en_voxceleb_resnet34_LM.onnx`](https://github.com/k2-fsa/sherpa-onnx/releases/download/speaker-recongition-models/wespeaker_en_voxceleb_resnet34_LM.onnx) (26.5 MB, SHA-256 `e9848563da86f263117134dfd7ad63c92355b37de492b55e325400c9d9c39012`) from the sherpa-onnx `speaker-recongition-models` release into `~/.omni-dev/voice/models/wespeaker-en-voxceleb-resnet34-LM/` via a direct `ureq` GET with SHA-256 verification and the same `.part` + atomic rename install pattern as the Whisper path. Both variants share the same `--dest`, `--force`, and idempotency semantics; the download transport bifurcates on the `ModelSource` carried by each variant's `ModelSpec`.
- **`WespeakerEmbedder` Speaker-Embedding Runtime** ([#805](https://github.com/rust-works/omni-dev/issues/805) / [ADR-0034](docs/adrs/adr-0034.md)): New `src/voice/speaker.rs` wraps `tract-onnx` v0.21 loading the wespeaker `voxceleb_resnet34_LM` ONNX model. `WespeakerEmbedder::new(path)` loads + optimises the ONNX graph and builds the FBANK mel filterbank + FFT plan once; `WespeakerEmbedder::embed(&[i16]) -> Vec<f32>` takes 16 kHz mono signed-PCM samples and returns a 256-dimensional L2-normalised embedding suitable for cosine similarity. Refuses windows shorter than 0.5 s (`MIN_EMBED_SAMPLES`) for which cepstral-mean normalisation would be unstable. `Send + Sync` because `SimplePlan::run` takes `&self`, allowing one embedder to be shared across worker threads without internal mutexing. Companion `EnrolledSpeaker` struct in the same module handles atomic load/save against the JSON storage convention, with `dim`/`vector.len()` parity verified on load. Free functions `cosine(&[f32], &[f32]) -> f32` and `l2_normalise(Vec<f32>) -> Vec<f32>` round out the public surface. Runtime choice documented in [SPIKE.md on `issue-805-spike-tract-speaker`] and [ADR-0034](docs/adrs/adr-0034.md). The `tract-linalg` build-dep on `cc` (compiling platform-conditional SIMD assembly stubs, not C++) is the same C-toolchain footprint already required by [ADR-0033](docs/adrs/adr-0033.md)'s `onig_sys`/`ring`.
- **`voice features` Kaldi-Style FBANK Module** ([#805](https://github.com/rust-works/omni-dev/issues/805)): New `src/voice/features.rs` implements 80-dim Kaldi-style FBANK feature extraction matching sherpa-onnx's `kaldi-native-fbank` defaults for the wespeaker recipe — 16 kHz mono, 25 ms / 10 ms framing, pre-emphasis 0.97, Hamming window, mel scale `1127·ln(1 + f/700)` (Slaney/Kaldi), low-freq 20 Hz / high-freq 8000 Hz, 512-point FFT (smallest power of two ≥ 400-sample window), log applied to mel energies with `1e-10` numerical floor, cepstral mean normalisation across the supplied window's frames. Pure-Rust DSP — only non-`std` dep is `rustfft` for the FFT. Public surface: `compute_fbank(pcm: &[f32], filters: &[Vec<f32>]) -> Result<Vec<Vec<f32>>>` and `build_mel_filterbank(num_bins, fft_size, sample_rate) -> Result<Vec<Vec<f32>>>`, plus the parameter constants (`SAMPLE_RATE`, `FRAME_LENGTH_MS`, `FRAME_SHIFT_MS`, `NUM_MEL_BINS`, `FFT_SIZE`, `LOW_FREQ_HZ`, `HIGH_FREQ_HZ`, `PREEMPHASIS`). Covered by 8 unit tests including filterbank dimensionality, non-negativity, monotonic centre-frequency ordering, frame-count formula correctness, CMN-zeros-mean-per-bin invariant, and `hz<->mel` round-trip stability.
- **`omni_dev::voice::paths` Helpers** ([#805](https://github.com/rust-works/omni-dev/issues/805)): New `src/voice/paths.rs` centralises `~/.omni-dev/voice/...` layout so capture, transcribe, install-model, and enroll all derive paths from one source of truth. Public functions: `omni_dev_voice_root() -> Result<PathBuf>`, `captures_dir() -> Result<PathBuf>`, `speakers_dir() -> Result<PathBuf>`, `speaker_file(name: &str) -> Result<PathBuf>`. `speaker_file` rejects empty names, path separators (`/` or `\`), null bytes, and `.`/`..` as a defence-in-depth guard against accidental directory traversal. `src/cli/voice/capture.rs::default_output_path` now routes through `captures_dir()` rather than open-coding the home-dir join.
- **`#[ignore]`-Gated `voice_enroll_speaker_test` Integration Test** ([#805](https://github.com/rust-works/omni-dev/issues/805)): New `tests/voice_enroll_speaker_test.rs` exercises `WespeakerEmbedder` end-to-end against the committed `tests/fixtures/voice/two_speakers.wav` fixture (two LibriVox readers, 24.5 s, public-domain). Asserts the same spike-aligned separability gates that ADR-0034 was accepted on: within-speaker cosine ≥ 0.70 (spike measured ≈ 0.91) and all six cross-speaker cosines ≤ 0.40 (spike measured ≈ 0.07). A second test verifies the default 0.5 threshold correctly accepts a same-speaker query window and rejects both other-speaker windows — the runtime contract `voice transcribe --speaker` depends on. Both tests are `#[ignore]`-by-default because they need the wespeaker ONNX file on disk; run locally with `omni-dev voice install-model --variant speaker-wespeaker-en` followed by `cargo test --test voice_enroll_speaker_test -- --ignored`, or point at a pre-staged install via `OMNI_DEV_VOICE_SPEAKER_MODEL`.
- **`whisper-candle` ASR Backend** ([#802](https://github.com/rust-works/omni-dev/issues/802)): New pure-Rust Whisper backend at `src/voice/backends/candle.rs` selected via `--backend whisper-candle` (or `OMNI_DEV_VOICE_BACKEND=whisper-candle`) on `omni-dev voice transcribe`. Built on `candle-core` / `candle-nn` / `candle-transformers` 0.10.x with `openai/whisper-tiny.en` (revision `refs/pr/15`), greedy decode (temperature 0), English-only, no timestamps; RTF ≈ 0.10 on CPU per the spike in #813. Emits one `TranscriptEvent::Final` per decoded mel segment (`event_id = Ulid::new()`, `confidence` from per-token average log-probability mapped via `avg_logprob.exp().clamp(0.0, 1.0)`, `words = None`, `speaker = None`, `revisable = false`) followed by a terminal `Endpoint { kind: StreamEnd }`. The `m::model::Whisper` handle is held behind a `Mutex` because its encoder and decoder methods take `&mut self` and the decoder owns a per-segment KV cache that concurrent calls would corrupt. Mel-filter coefficients (80-bin, 64 KB) are vendored as `src/voice/backends/candle_melfilters.bytes` and embedded via `include_bytes!`. Model files are loaded from a directory resolved with priority `--model <path>` → `OMNI_DEV_VOICE_WHISPER_MODEL` → `~/.omni-dev/voice/models/whisper-tiny.en/`; missing-model errors carry an actionable install hint pointing at `voice install-model`. Default backend remains `mock` until the model storage convention has been through at least one release cycle. Recorded in [ADR-0033](docs/adrs/adr-0033.md). Covered by unit tests for `Send + Sync`, mel-filter shape, the missing-model error path, factory dispatch, and a `#[ignore]`-by-default end-to-end test at `tests/voice_transcribe_candle_test.rs` that exercises the backend against the committed `short_en.wav` fixture with case-insensitive substring matching on the seven content words from the #813 baseline.
- **`omni-dev voice install-model` Subcommand** ([#802](https://github.com/rust-works/omni-dev/issues/802)): New one-time CLI command at `src/cli/voice/install_model.rs` downloads the Whisper tiny.en `config.json`, `tokenizer.json`, and `model.safetensors` from `openai/whisper-tiny.en` (revision `refs/pr/15`) into `~/.omni-dev/voice/models/whisper-tiny.en/` via `hf-hub`. `--dest <path>` overrides the install directory; `--force` re-downloads when files are already present. Idempotent — skips when all three required files exist and are non-empty. Atomic — each file is staged as a `.<name>.part` sibling and renamed into place, so partial downloads never leave half-written model artifacts at the destination. Progress lines (`fetching <file>... done (N bytes in M.Ms)`) are emitted to stderr so stdout stays free for future machine-readable additions. Bumps the model-download cost to install time rather than transcribe time so network failures surface explicitly when the user opts in to installing rather than silently on first `voice transcribe`.
- **`--model <path>` Flag on `voice transcribe`** ([#802](https://github.com/rust-works/omni-dev/issues/802)): `omni-dev voice transcribe` now accepts `--model <path>` to override the backend's model directory (for `whisper-candle`, this overrides `OMNI_DEV_VOICE_WHISPER_MODEL` and the default at `~/.omni-dev/voice/models/whisper-tiny.en/`). The flag is plumbed through to `VoiceOpts.model` (previously hardcoded `None`) and is ignored by the `mock` backend. The shared `src/voice/models.rs` helper centralises three-tier path resolution so the backend's load path and `install-model`'s download path can't diverge.

### Changed
- **`jira_field_list` Exposes `schema.custom` and Maps Rich-Text Fields** ([#865](https://github.com/rust-works/omni-dev/issues/865)): The `omni-dev atlassian jira field list` CLI and matching `jira_field_list` MCP tool now report `schema_type: "richtext"` for ADF-required custom fields (e.g. *Acceptance Criteria*) and expose the raw plugin URI from `schema.custom` as a new `schema_custom` field. Callers — including AI agents — can detect rich-text fields up front instead of discovering them via a `400 "Operation value must be an Atlassian Document"` on the first write attempt. Previously the JIRA API's `schema.custom` value (e.g. `com.atlassian.jira.plugin.system.customfieldtypes:textarea`) was deserialised and discarded; `schema_type` reported `"string"` indistinguishably from plain string fields. Implementation extends `JiraFieldSchema` to deserialise `custom`, adds `JiraField.schema_custom: Option<String>` (`#[serde(skip_serializing_if = "Option::is_none")]` so non-custom fields stay shape-compatible), and routes `(schema.type, schema.custom)` through a new file-private `map_schema_type` helper in `src/atlassian/client.rs::get_fields` that returns `"richtext"` when `schema.custom == "...customfieldtypes:textarea"` and passes everything else through unchanged. The textarea URI is consolidated into a `pub(crate) const TEXTAREA_CUSTOM_TYPE` shared with the existing `EditMetaField::is_adf_rich_text` discriminator. The CLI table's TYPE column picks up the new value transparently; the MCP tool description is extended to document the new contract for agent enumeration. Behaviour change for consumers that compared `schema_type` against the literal `"string"` for textarea custom fields — they now see `"richtext"`, which is more accurate.
- **`src/voice/models.rs` Generalised to `ModelSpec` Shape** ([#805](https://github.com/rust-works/omni-dev/issues/805)): The Whisper-only constants from #802 are now exposed through a `ModelSpec` struct (with a sibling `ModelSource` enum carrying either `HfHub { repo_id, revision }` or `HttpReleaseAsset { url, sha256, bytes }`) so the same registry hosts both ASR (Whisper, HfHub-sourced) and speaker (wespeaker, GitHub-release-asset-sourced) models. Two canonical instances are registered: `WHISPER_TINY_EN` and `SPEAKER_WESPEAKER_EN`. `ModelSpec` exposes `default_dir()`, `resolve_dir(override)`, `required_files_in(dir)`, and `ensure_present(dir)` as methods; the last carries the variant-specific install hint baked into the spec (`run \`omni-dev voice install-model\` or pass --model <path>` for Whisper, `run \`omni-dev voice install-model --variant speaker-wespeaker-en\` or pass --speaker-model <path>` for wespeaker). All pre-existing Whisper helpers (`MODEL_ID`, `REVISION`, `REQUIRED_FILES`, `DEFAULT_VARIANT_DIR`, `default_whisper_model_dir`, `resolve_whisper_model_dir`, `ensure_model_present`, `required_files_in`) are retained as thin shims over `WHISPER_TINY_EN`, so existing callers in `src/voice/backends/candle.rs`, `src/voice/factory.rs`, and `src/cli/voice/install_model.rs` keep compiling with no signature change.

### CI/CD
- **Release Workflow Ships `omni-dev-mcp` Binary** ([#874](https://github.com/rust-works/omni-dev/pull/874)): The `release.yml` workflow now builds with `--features mcp --bin omni-dev --bin omni-dev-mcp` and includes both binaries in the per-platform release archives (Linux/macOS/Windows). The MCP server binary was previously buildable from source but missing from GitHub release assets. Both binaries are stripped on linux and macos.

## [0.26.0] - 2026-05-11

### Added
- **ADF Validator: Per-Context Mark Allow-Lists & Per-Mark Attribute Schemas** ([#733](https://github.com/rust-works/omni-dev/issues/733)): `validate_document` now flags two more violation classes — `DisallowedMark { mark_type, parent_type, inline_index, path }` (e.g. a `code` mark on text inside a `heading`, a `border` block mark on a `paragraph`) and `InvalidMarkAttr { mark_type, attr_name, problem, inline_index, path }` (e.g. `link.href: "not a url"`, `subsup.type: "side"`, `border.size: 5`). Inline-mark allow-lists are keyed by the *parent* container (since `code` is fine on `paragraph` text but not on `heading` text); block-mark allow-lists are keyed by the node's *own* type (since `border`/`backgroundColor` are valid on `tableCell` and `tableHeader` only, while `alignment`/`indentation` are valid on `paragraph` and `heading` only). Per-mark attribute schemas reuse the `AttrSchema` / `AttrType` / `AttrProblem` machinery from the attribute slice — `link` requires an absolute-URL `href`, `subsup` requires `type ∈ {sub, sup}`, `alignment` requires `align ∈ {start, end, center, right, left}`, `indentation` requires `level ∈ 1..=6`, `breakout` requires `mode ∈ {wide, full-width}`, `border` requires hex `color` and `size ∈ 1..=3`, `annotation` requires `id` and `annotationType`. `unsupportedMark` and `unsupportedNodeAttribute` are accepted under any context as round-trip preservation wrappers (matching `unsupportedBlock`/`unsupportedInline`'s treatment in #717). Per-mark and per-context hints are added to `adf_hints` (`headings cannot carry the code mark — use a paragraph if you need code styling`, `link.href must be an absolute URL`, etc.). New module: `src/atlassian/adf_mark_schema.rs`. Modified: `src/atlassian/adf_schema.rs` (new `DisallowedMark` / `InvalidMarkAttr` enum variants + walker calls `validate_marks` for every visited child), `src/atlassian/adf_attr_schema.rs` (`check_value` made `pub` so the mark module can reuse type-checking), `src/atlassian/error.rs` (Display arms for the new variants), `src/atlassian/adf_hints.rs` (per-mark hint tables). Covered by 22 unit tests in `adf_mark_schema` (allow-list per parent context, block-mark contexts, mark-attr happy/sad path per mark type), 2 new integration tests in `tests/adf_schema_test.rs` exercising `code`-on-heading and malformed `link.href` through `validate_document`, and a new `print_dry_run_fails_on_disallowed_mark` end-to-end test in the CLI helper.
- **ADF Validator: Per-Node Attribute Schemas** ([#733](https://github.com/rust-works/omni-dev/issues/733)): `validate_document` now validates each node's `attrs` against a per-node-type schema and reports two new violation variants — `MissingAttr { node_type, attr_name, path }` and `InvalidAttr { node_type, attr_name, problem, path }`. The `problem` field carries an `AttrProblem` enum (`NotInEnum { allowed, actual }`, `OutOfRange { lo, hi, actual }`, `OutOfRangeF { … }`, `WrongType { expected }`, `BadFormat { reason }`) so display wording is centralised. Schemas are encoded in a new `src/atlassian/adf_attr_schema.rs` module for the user-visible mistakes called out in the issue (`panel.panelType ∈ {info, note, warning, success, error, custom}`, `heading.level ∈ 1..=6`) and for the rest of the typed attrs across the snapshot: `media.type` (file/link/external), `mediaSingle.layout`, `taskItem`/`decisionItem` `state` and `localId`, `taskList`/`decisionList.localId`, `status.color` and `text`, `extension.extensionType`/`extensionKey`, `mention.id`, `date.timestamp`, `emoji.shortName`, `embedCard.url` (URL-parseable), `expand.title`, `nestedExpand.title`, `orderedList.order` (positive integer), `layoutColumn.width` (0–100), `codeBlock.language`, plus more. Forward-compatibility preserved per ADR-0023's permissive philosophy: unknown node types and unknown attribute names trigger no violation; explicit `null` is treated as absent. Per-attribute hints are added to the `adf_hints` module (`set panelType to one of: info, note, warning, success, error, custom`, `heading.level must be an integer in 1..=6`, etc.). Reuses the shared `AttrSchema` / `AttrType` machinery — designed to be reused by mark-attribute validation in the third sub-PR. Modified: `src/atlassian/adf_schema.rs` (new `MissingAttr` / `InvalidAttr` enum variants + walker calls `validate_attrs` for every visited child), `src/atlassian/error.rs` (Display arms for the new variants), `src/atlassian/adf_hints.rs` (per-attr hint table), `src/atlassian/adf_attr_schema.rs` (new module). Covered by 21 unit tests in `adf_attr_schema`, 9 integration tests in `tests/adf_schema_test.rs`, and a new `print_dry_run_fails_on_invalid_attribute` end-to-end test exercising `panelType: "purple"` through the CLI helper.
- **ADF Validator: Quantifier / Arity Checks** ([#733](https://github.com/rust-works/omni-dev/issues/733)): `validate_document` now flags arity violations alongside the existing disallowed-child checks. `mediaSingle` with two `media` children, an empty `bulletList`, an empty `mediaGroup`, an empty `tableRow`, and a `layoutSection` with the wrong number of columns (must be 2 or 3) are all reported as `AdfSchemaViolation::Arity { parent_type, atoms, expected, actual, path }`. The `expected` field carries a new `Quantifier` enum (`ZeroOrOne`, `ZeroOrMore`, `OneOrMore`, `Exactly(n)`, `Range(min, max)`); `path` points at the parent whose count is wrong (whereas `DisallowedChild`'s `path` points at the child). Disallowed children do **not** count toward parent arity — an empty panel containing only an `expand` produces both a `DisallowedChild` (for the expand) and an `Arity` (for the panel needing ≥1 valid child). `unsupportedBlock` / `unsupportedInline` continue to be accepted under any known parent **and** count toward the parent's current term arity, so round-tripped documents carrying preservation wrappers still satisfy `+` / `Exactly(n)` requirements. Two upstream rules are intentionally relaxed for compatibility with real-world inputs: `doc` is `block*` instead of `block+` (so `AdfDocument::new()` — the canonical empty value for missing JIRA descriptions — does not trigger an arity violation) and `tableCell` / `tableHeader` are `block*` instead of `block+` (visibly-empty cells in real Confluence tables are common and accepted by the renderer). The `confluence write --dry-run` output and the HTTP-500 diagnosis in `confluence_write_error` both pick up the new variant via the existing `Display` impl, with arity-specific wording (`'bulletList' must contain at least one 'listItem' (found 0)`). Per-arity hints (empty list, two-media mediaSingle, layoutSection out-of-range, …) are added to the new `adf_hints` module. New module: `src/atlassian/adf_hints.rs`. Modified: `src/atlassian/adf_schema.rs` (full content-model rewrite + new `Quantifier` / `ContentTerm` types + new walker), `src/atlassian/error.rs` (Display switches per variant), `src/atlassian/confluence_api.rs` (uses `adf_hints::hint_for(&violation)`). Covered by 41 unit tests in `adf_schema` plus 6 unit tests in `adf_hints` plus 6 integration tests in `tests/adf_schema_test.rs`.

### Changed
- **`AdfSchemaViolation` Struct → Enum (Breaking)** ([#733](https://github.com/rust-works/omni-dev/issues/733)): The single concrete `AdfSchemaViolation` struct from #717 is now an enum so each new class of violation lands as its own variant (callers can opt in to strictness). The first variant `DisallowedChild { child_type, parent_type, path }` carries the existing fields verbatim — same `Display` wording, same path semantics — so the only migration is updating constructions and pattern-matches in callers. The second variant `Arity { … }` is added in the same release for the quantifier slice. Public `validate_document(&AdfDocument) -> Vec<AdfSchemaViolation>` signature is unchanged. The `hint_for` helper formerly inside `confluence_api.rs` moves to the new dedicated `src/atlassian/adf_hints.rs` module and now takes `&AdfSchemaViolation` so it can dispatch per variant. New `pub fn content_model(parent: &str) -> Option<&'static [ContentTerm]>` exposes the full per-parent term sequence (with quantifiers) for callers that want richer schema introspection than `allowed_children` provides.
- **OpenAI/Ollama Backends Enforce JSON Schema Response Format** ([#702](https://github.com/rust-works/omni-dev/issues/702)): `OpenAiAiClient` (used by `USE_OLLAMA=true`, `USE_OPENAI=true`, and OpenAI-compatible servers like LM Studio) now honours `RequestOptions::response_schema` by populating `response_format: {type: "json_schema", json_schema: {name, strict, schema}}` on `/v1/chat/completions`. Previously the option was silently dropped and the backend reported `supports_response_schema = false`, so structured calls (twiddle, check, PR generation) received hard-validated JSON only on `claude-cli` and prose-instructed YAML everywhere else — the most visible symptom being invented commit scopes that were not in `.omni-dev/scopes.yaml`. Capability flips to `true` on both OpenAI and Ollama paths; the existing capability-driven dispatch in `client.rs::send_with_optional_schema` and the `ResponseFormat::JsonSchema` system-prompt swap pick up the change with no further wiring. Honoured by OpenAI ≥2024-08-06 (gpt-4o, gpt-5, o-series), LM Studio (decoder-constrained), and Ollama ≥0.5; older servers either 400 with a clear "model does not support structured output" error (a surface change for those users — schema enforcement was never available there before, and the error names the cause) or silently ignore the field and emit prose (matching today's behaviour). The wire body is byte-identical to today's when no schema is attached, guarded by `#[serde(skip_serializing_if = "Option::is_none")]` on the new `OpenAiRequest::response_format` field. The schema registry's existing types (`AmendmentFile`, `PrContent`, `AiCheckResponse`) were tightened to satisfy OpenAI's strict-subset rule that every property in `properties` must also appear in `required`: `Amendment.summary` becomes a non-optional `String` (defaulting to empty for graceful YAML loading), `AiCommitCheck` and `AiIssue` use `#[schemars(extend("required" = [...]))]` to force `Option<T>` and serde-defaulted fields into `required` while preserving nullability via `type: ["...", "null"]`. A new CI test (`schemas_satisfy_openai_strict_subset` in `src/claude/response_schema.rs`) walks each schema and asserts the invariant, catching drift the moment any new optional field is added without an `extend(...)` override. Implementation localised to `src/claude/ai/openai.rs` (~150 LOC including tests) plus the schema-shape adjustments; covered by serde-level body-shape tests, wiremock round-trip tests for both schema-bearing and schemaless paths, and the new strict-subset CI check.

### Added
- **TTL-Bounded In-Memory Cache for JIRA Catalogue MCP Tools** ([#719](https://github.com/rust-works/omni-dev/issues/719)): New `src/mcp/catalogue_cache.rs` module wraps the four near-static JIRA catalogue endpoints (`jira_link_types`, `jira_field_list`, `jira_project_list`, `jira_board_list`) so repeated MCP invocations within a server-process lifetime collapse to a single HTTP request per catalogue per hour, instead of rebuilding an `AtlassianClient` and hitting JIRA every time. `CatalogueCache` lives as `Arc<CatalogueCache>` on `OmniDevServer`; each catalogue has its own `tokio::sync::RwLock<Option<CacheEntry<T>>>` slot, with single-flight via the read-fast-path / write-on-miss / double-check pattern (no extra mutex). Entries are tagged with the issuing `instance_url` and refetched on drift. Failed fetches do not poison the cache — they propagate the error and leave the slot untouched. Default TTL is 1 hour (`DEFAULT_TTL`), constructible with arbitrary `Duration` for tests. Parameterised methods (`get_projects(limit)`, `get_boards(project, board_type, limit)`) cache the *unfiltered, unbounded* result; the YAML helpers (`project_list_yaml`, `board_list_yaml`, `field_list_yaml`) apply limit/filter to the cached `Arc<…>` at serve time so the hit rate is independent of caller arguments. CLI commands remain uncached (one-shot per process; nothing to amortise). Recorded in [ADR-0024](docs/adrs/adr-0024.md). Covered by 7 wiremock tests in `catalogue_cache.rs` (per-catalogue cache hit, TTL expiry, instance-url drift, error propagation) plus updated `*_yaml` helper tests for the four affected helpers.
- **ADF Schema Validation in `confluence write --dry-run`** ([#718](https://github.com/rust-works/omni-dev/issues/718)): `omni-dev atlassian confluence write --dry-run` now runs the ADF schema validator from [#717](https://github.com/rust-works/omni-dev/issues/717) over the converted ADF after printing the JSON output, prints a `Validation:` section that reports either `OK` or one line per violation (using the `AdfSchemaViolation` `Display` impl, e.g. `✗ ADF schema violation at /0/0: 'expand' is not permitted inside 'panel'`), and exits non-zero when any violation is found. Acts as a CI pre-flight check that surfaces what Confluence would otherwise reject silently or with HTTP 500. First wiring point for the soft-launched validator; the converter fix and non-dry-run / MCP wiring are tracked in [#730](https://github.com/rust-works/omni-dev/issues/730). Implemented as a ~20-line addition to `print_dry_run` in `src/cli/atlassian/helpers.rs`; covered by a new `print_dry_run_fails_on_schema_violation` unit test that exercises the `panel`-containing-`expand` case.
- **Data-Driven ADF Content-Model Schema and Validator** ([#717](https://github.com/rust-works/omni-dev/issues/717)): New `src/atlassian/adf_schema.rs` module encodes the full allowed-children content model from the upstream `@atlaskit/adf-schema` npm package, transcribed faithfully from `json-schema/v1/full.json` of the pinned tarball (version `52.9.5`, SHA-256 `90b9b26f5cdf6f0850cebe5cf2df7662601b249322d6bcbeead712ca018e0b56`, recorded in `SCHEMA_VERSION` and `UPSTREAM_TARBALL_SHA256` constants). Storage is a static `LazyLock<HashMap<&str, &[&str]>>` lookup; public helpers are `allowed_children(parent)`, `permits_child(parent, child)`, and a depth-first walker `validate_document(&AdfDocument) -> Vec<AdfSchemaViolation>` that reports nesting violations in document order with `parent_type`, `child_type`, and an index `path` from the document root. Covers every container node type in the upstream schema: `doc`, `paragraph`, `heading`, `panel`, `expand`, `nestedExpand`, `blockquote`, `bulletList`/`orderedList`/`listItem`, `tableCell`/`tableHeader`/`tableRow`/`table`, `layoutSection`/`layoutColumn`, `taskList`/`taskItem`/`blockTaskItem`, `decisionList`/`decisionItem`, `mediaSingle`/`mediaGroup`/`caption`, `codeBlock`, `bodiedExtension`, `bodiedSyncBlock`. Forward-compat preserved per [ADR-0020](docs/adrs/adr-0020.md) via two complementary mechanisms: unknown parent node types are treated permissively (their subtrees are not walked, so future Atlassian schema additions don't fail validation), and `unsupportedBlock`/`unsupportedInline` are accepted under any known parent via a walker-level short-circuit (the upstream JSON schema does not list these wrappers in any parent's allowed-children set, so faithfulness to upstream and round-trip survival can only coexist via the escape hatch). Unknown *children* under known parents are still flagged. Soft launch — the validator is a public library function, not wired into `markdown_to_adf` or any write path; the existing converter still emits structurally invalid ADF (the `nested_expand_inside_panel` and `nested_expand_inside_table_cell` tests document this) and fixing the converter to produce only schema-valid output is tracked as a separate effort. Recorded in [ADR-0023](docs/adrs/adr-0023.md). Covered by 20 unit tests (issue-#717 examples, sortedness invariants, walker depth-first ordering, permissiveness on unknown parents *and* unknown root doc_type, `unsupportedBlock`/`unsupportedInline` walker escape hatch with positive *and* negative assertions on the underlying allowed-children sets) plus 4 integration tests exercising the public API through `AdfDocument::from_json_str`; 100% line and region coverage on the new module. Deferred to follow-ups: converter fix + write-path enforcement ([#730](https://github.com/rust-works/omni-dev/issues/730)), CI drift detection against upstream ([#731](https://github.com/rust-works/omni-dev/issues/731)), code-generation from npm ([#732](https://github.com/rust-works/omni-dev/issues/732)), validator coverage beyond nesting (quantifiers, marks, attribute schemas — [#733](https://github.com/rust-works/omni-dev/issues/733)).
- **ADF Nesting Validation Wired Into API Send Path** ([#714](https://github.com/rust-works/omni-dev/issues/714), follow-up to [#717](https://github.com/rust-works/omni-dev/issues/717)): The schema validator from [#717](https://github.com/rust-works/omni-dev/issues/717) / [ADR-0023](docs/adrs/adr-0023.md) is now enforced at every API send site, so JFM → ADF conversions that produce structurally invalid ADF (e.g., `expand` inside `panel`) abort locally with an actionable message rather than surfacing as opaque HTTP 500s from Confluence. A new `src/atlassian/adf_validated.rs` module exposes a `ValidatedAdfDocument` newtype whose only fallible constructor (`try_new`) runs `adf_schema::validate_document`; the type system enforces "validated once before send" by giving every API send signature (`AtlassianApi::update_content`, `AtlassianClient::{update_issue, update_issue_with_custom_fields, create_issue, create_issue_with_custom_fields, add_comment, update_comment}`, `ConfluenceApi::{create_page, add_page_comment, update_content}`, plus per-section validation in `custom_fields.rs` for rich-text JIRA custom fields) a `&ValidatedAdfDocument` parameter rather than `&AdfDocument`. Errors are surfaced via a new `AtlassianError::InvalidAdfNesting` variant wrapping `AdfValidationError`, formatted as ``invalid ADF nesting — `expand` cannot be a child of `panel` at /0/0. hint: invert the nesting (put the panel inside the expand) or use siblings.`` — the path comes from the upstream walker, the per-(parent, child) hint table covers the high-traffic combinations called out in #714 (panel↔expand, table-cell-or-header↔expand, layout-section nesting, blockquote / list-item containment) with a generic ``"restructure the document so X is not a direct child of Y."`` fallback for any other forbidden pair. All violations are collected so the user can fix multiple issues in one editor pass. The `omni-dev atlassian convert to-adf` CLI also validates by default and accepts a new `--no-validate` flag for users inspecting invalid ADF for debugging. The existing `nested_expand_inside_panel()` and `nested_expand_inside_table_cell()` regression tests now assert that validation rejects the converted document, replacing assertions that the converter still emits these constructs (the converter fix is tracked in [#730](https://github.com/rust-works/omni-dev/issues/730)); `nested_expand_inside_layout_column()` is preserved as a positive case (`expand` inside `layoutColumn` is legitimate per the schema). Architecture decision recorded in [ADR-0025](docs/adrs/adr-0025.md).
- **Discrete `jira_link_list` / `jira_link_types` / `jira_link_remove` MCP Tools** ([#711](https://github.com/rust-works/omni-dev/issues/711)): Three new MCP tools mirror the existing `omni-dev atlassian jira link {list,types,remove}` CLI subcommands by re-exposing the existing `AtlassianClient::{get_issue_links,get_link_types,remove_issue_link}` methods individually, alongside the existing dispatch-style `jira_link` tool (which stays for back-compat). `jira_link_list(key)` returns inward + outward links with link type and target issue summary; `jira_link_types()` returns the configured link-type catalogue (id, name, inward, outward) — global per JIRA instance, not the types used in any particular issue; `jira_link_remove(link_id)` returns YAML `{status: ok}`. Pattern mirrors the existing `jira_watcher_{list,add,remove}` triplet. No new client methods. Implemented in `src/mcp/jira_tools.rs` (params structs, `*_yaml` helpers, three `#[tool]` handlers) with six wiremock unit tests covering each helper's happy path plus a 404-on-remove acceptance test, and registration tests updated in `src/mcp/server.rs` and `tests/mcp_integration_test.rs`. Caching of the link-types catalogue (which is near-static) is deferred to [#719](https://github.com/rust-works/omni-dev/issues/719); confirmation-flag conventions for destructive CLI operations are deferred to [#720](https://github.com/rust-works/omni-dev/issues/720).
- **Confluence Page Version History** ([#708](https://github.com/rust-works/omni-dev/issues/708)): New `omni-dev atlassian confluence history <id>` CLI subcommand and matching `confluence_history` MCP tool list version metadata for a Confluence page (number, ISO timestamp, author account ID, edit message, minor-edit flag), newest-first. Pure metadata — no body fetch — so the structural-diff feature in [#706](https://github.com/rust-works/omni-dev/issues/706) can resolve `from`/`to` references without inlining version-list logic. `--since` accepts either a numeric version (`5`) or an ISO 8601 date (`2026-01-01T00:00:00Z`); newest-first ordering means a date or version cutoff terminates pagination early. `--limit` defaults to 20 with `0 = unlimited`, matching the `comment list` / `label list` convention. Output supports `-o table|json|yaml|yamls|jsonl` and emits `{ page: { id, title, current_version }, versions: [...], truncated }`. Backed by a new `ConfluenceApi::list_page_versions` (auto-paginates `/wiki/api/v2/pages/{id}/versions?limit=&cursor=`, applies the `since` filter client-side, returns a `truncated` flag when `limit` cuts the listing short) plus a lightweight `get_page_metadata` that skips the body and space-key lookup. Tolerates null `authorId`/`createdAt`/`message` per the issue's risk #1. Implemented in `src/atlassian/confluence_api.rs`, `src/cli/atlassian/confluence/history.rs`, and `src/mcp/confluence_tools.rs`; covered by wiremock tests for pagination, numeric/ISO `since` filters, early termination at the cutoff, missing-field tolerance, `limit` truncation, empty results, and API-error propagation across the API, CLI, and MCP layers.
- **`jira_transition_list` MCP Tool & `transition list` CLI Subcommand** ([#710](https://github.com/rust-works/omni-dev/issues/710)): New single-purpose MCP tool `jira_transition_list(key)` and CLI subcommand `omni-dev atlassian jira transition list <KEY>` expose JIRA workflow transitions without forcing a full `jira_read` round-trip. Returns YAML with `{id, name, to_status: {id, name, category}, has_screen}` for each transition — the richer shape mirrors what sooperset/mcp-atlassian publishes, so agent prompts trained against that surface work unchanged. Equivalent to `jira_transition` with `list = true` (which is preserved for backward compatibility), but the dedicated tool is easier for LLM agents to discover. Implemented in `src/mcp/jira_core_tools.rs` (new `JiraTransitionListParams`, `run_jira_transition_list`, `jira_transition_list` tool method) and `src/cli/atlassian/jira/transition.rs`, with `JiraTransition` extended in `src/atlassian/client.rs` to expose the `to_status` and `has_screen` fields previously discarded by the deserialiser. Covered by new wiremock tests for happy path, 404 issue-not-found, empty transitions array, and a richly-populated response body.
- **Destructive CLI Commands: `--dry-run` Flag** ([#720](https://github.com/rust-works/omni-dev/issues/720)): All five destructive Atlassian subcommands (`omni-dev atlassian jira delete`, `omni-dev atlassian confluence delete`, `omni-dev atlassian jira watcher remove`, `omni-dev atlassian jira link remove`, `omni-dev atlassian confluence label remove`) now accept `--dry-run`, which prints `Would <verb> <target>.` and returns without making any API calls. `--dry-run` takes precedence over `--force`, so a script author can add `--dry-run` to an existing scripted `--force` invocation as a temporary safety check without removing the force flag. The `confluence label remove --dry-run` preview is purely client-side: labels are echoed back verbatim without verifying they exist on the page (documented trade-off in [ADR-0027](docs/adrs/adr-0027.md)). A new shared helper `src/cli/atlassian/confirm.rs` exposes `guard_destructive(opts) -> GuardOutcome { Proceed | Cancelled | DryRun }` and replaces the two duplicated `confirm_with_reader` copies that previously lived inline in `jira/delete.rs` and `confluence/delete.rs`. The decision is recorded in [ADR-0027](docs/adrs/adr-0027.md).
- **CI Drift Detection vs Upstream `@atlaskit/adf-schema`** ([#731](https://github.com/rust-works/omni-dev/issues/731)): A new `adf-schema-drift` binary plus a weekly scheduled GitHub Actions workflow (`.github/workflows/adf-schema-drift.yml`, also manual-dispatch) detect drift between the locally-encoded schema snapshot and the upstream npm package, opening or updating an issue labelled `adf-schema-drift` when drift is detected. The Rust implementation lives in a new `src/atlassian/adf_schema/drift.rs` module exposing `DriftReport` / `ParentDrift` value types, an HTTP-backed upstream tarball fetcher with `reqwest` (overridable per `OMNI_DEV_ADF_SCHEMA_LATEST_URL` for test injection) that verifies the response SHA-256 via `sha2`, a `.tgz` extraction routine using `flate2` + `tar`, and a JSON-schema parser tolerant of `anyOf` / `allOf` alias chains and marks-overlay definitions (refs into marks subtrees are filtered out so they do not leak into content children). The `adf-schema-drift` CLI binary (`src/bin/adf_schema_drift.rs`) takes `--format markdown|json|both` and `--output-dir`, writes `drift-report.md` / `drift-report.json`, and emits `drift=<bool>` / `version_changed=<bool>` to stdout and `$GITHUB_OUTPUT`. Adds `flate2`, `tar`, and `sha2` to `Cargo.toml`. Covered by wiremock-backed integration tests that spawn the compiled binary against synthesised upstream responses (success, 4xx, 5xx, connection refused, output-path failure modes).
- **`adf-schema-codegen` Binary and Vendored Upstream Schema Assets** ([#732](https://github.com/rust-works/omni-dev/issues/732)): The hand-transcribed `CONTENT_ENTRIES` allowed-children table is no longer the sole source of truth for the ADF nesting model. A new `adf-schema-codegen` binary (registered in `Cargo.toml`, sourced from `src/bin/adf_schema_codegen.rs`) reads `assets/adf-schema/full.json` plus its `provenance.json` sidecar (npm package, version, tarball URL, tarball SHA-256, `full.json` SHA-256), verifies the input via SHA-256 before generating, parses the upstream JSON schema via the existing `parse_upstream_full_json` function from `drift.rs` (now `pub` for reuse), and emits a deterministic `src/atlassian/adf_schema/generated.rs` formatted through `rustfmt`. A `--check` mode exits non-zero if the committed `generated.rs` is stale, suitable as a CI staleness gate. The vendored tarball assets (`assets/adf-schema/full.json`, `provenance.json`, and a refresh-workflow `README.md`) are checked into the repository. Two new tests assert (a) the generated `UPSTREAM_ENTRIES` slice agrees with the hand-maintained `CONTENT_ENTRIES` modulo a documented leniency allowlist, and (b) the vendored provenance SHA and npm version match the runtime `SCHEMA_VERSION` / `UPSTREAM_TARBALL_SHA256` constants.
- **Confluence HTTP 500 ADF Diagnosis** ([#715](https://github.com/rust-works/omni-dev/issues/715)): When a Confluence write returns HTTP 500, the error now includes a structured diagnosis pointing at the offending ADF nesting and an actionable hint, rather than surfacing as opaque `ApiRequestFailed`. A new helper `confluence_write_error` runs `adf_schema::validate_document` over the submitted payload at error time, returning a new `AtlassianError::ApiRequestFailedWithDiagnosis` variant whose `Display` impl produces a multi-line message — header, `Diagnosis:` line naming the offending parent/child, and an optional `Hint:` line — and intentionally omits the raw response body (which is logged at `debug!` by the call site). A `hint_for(parent, child)` table maps known bad pairs (`expand` inside `panel`, nested `expand` inside `expand`, etc.) to fix suggestions. Wired into `ConfluenceApi::{update_content, create_page, add_page_comment}`. Covered by integration tests for both the 500-with-violation and 500-without-violation paths across all three write operations.
- **Confluence Page Version Comparison** ([#706](https://github.com/rust-works/omni-dev/issues/706)): New `omni-dev atlassian confluence compare run|section` CLI surface and matching `confluence_compare` / `confluence_compare_section` MCP tools perform a structural diff between two versions of a Confluence page using an ADF-tree-aware engine rather than raw text diffing. The engine in `src/atlassian/diff.rs` splits documents into heading-delimited sections identified by stable slug paths (e.g. `/h2#background`), pairs nodes via a three-tier matcher (natural-key via `localId` / `url` / `id` attrs → content-hash → positional), then dispatches per-block: paragraphs and code blocks get word-level inline deltas via the `similar` crate, tables get cell-level pairing, lists get item-level pairing, and everything else falls back to opaque tree-equality. Three output detail levels — `summary` (counts only), `outline` (per-section change kind + drill-in cursors), `full` (embedded deltas, byte-budget-truncated via binary search to fit ~16 KiB / ≈4000 tokens) — let agents request progressively more detail; the `compare_section` drill-in tool decodes a stateless base64url cursor encoding `{page_id, from_v, to_v, section_path}` to re-fetch a single section in `unified`, `side-by-side`, or `markdown-inline` text format. Section-level filters (path, change kind, `min_change_chars`) are honoured by both surfaces. `ConfluenceApi` gains `get_page_at_version` and `resolve_version` (accepting `latest`, `previous`, `v-N`, numeric, or ISO 8601 date references). Adds `similar = "2.7"` to dependencies.
- **Confluence Page Move** ([#707](https://github.com/rust-works/omni-dev/issues/707)): New `omni-dev atlassian confluence move <id> --position append|before|after [--target <id>]` CLI subcommand and matching `confluence_move` MCP tool reparent or reorder a page within its current space via the v1 `PUT /wiki/rest/api/content/{id}/move/{position}/{target}` endpoint. Cross-space moves are not supported by the v2 API and are out of scope. `ConfluenceApi::move_page` returns a `MovedPage` whose ancestor chain is freshly fetched via `fetch_page_with_ancestors` (`GET /wiki/api/v2/pages/{id}?include-ancestors=true`) so callers see the post-move parent. Case-insensitive `parse_move_position` allows agents to pass the position as a string. Explicit 403 / 404 error messages distinguish permission-denied from missing-target.
- **Confluence Attachment Management** ([#709](https://github.com/rust-works/omni-dev/issues/709)): New `omni-dev atlassian confluence attachment upload|list|delete` CLI subcommands and matching `confluence_attachment_upload` / `confluence_attachment_list` / `confluence_attachment_delete` MCP tools cover end-to-end management of page attachments. Uploads are streamed via a new `AtlassianClient::post_multipart` helper with `X-Atlassian-Token: no-check` and no auto-429-retry (streamed bodies are non-replayable); the file is never fully buffered in memory. List is explicitly cursor-paginated — callers control page traversal, unlike the auto-draining label helpers — and `delete` honours an optional `purge: bool` flag that hard-deletes the attachment row rather than tombstoning it. The CLI `delete` subcommand prompts for confirmation by default (`--force` skips). Adds `mime_guess` to deps and enables `multipart` + `stream` features on `reqwest`; `tokio-util` becomes unconditional with `codec` + `io` features.
- **JIRA Project Version Management** ([#712](https://github.com/rust-works/omni-dev/issues/712)): New `omni-dev atlassian jira version list|create` CLI subcommands and matching `jira_version_list` / `jira_version_create` MCP tools manage JIRA project release versions. `list` returns a `JiraProjectVersionList` filterable by `--released true|false` and `--archived true|false` (tri-state — flag absent means "any"). `create` validates the `YYYY-MM-DD` release date up-front via a new `validate_iso_date` helper so callers see a clear error rather than JIRA's opaque 400. The slice also extracts `EnvGuard` and `AUTH_ENV_MUTEX` from the existing `atlassian::auth::tests` into a new `pub(crate) test_util` module so every Atlassian-touching test shares a single process-wide env-serialisation mutex, eliminating cross-test flakiness when several tests mutate `ATLASSIAN_TOKEN` / `ATLASSIAN_USER` / `ATLASSIAN_DOMAIN` concurrently; pre-existing inline guards in `confluence_tools`, `jira user`, and `confluence download` were migrated to the shared mutex.
- **JIRA Comment Edit** ([#713](https://github.com/rust-works/omni-dev/issues/713)): New `omni-dev atlassian jira comment edit <ISSUE> <COMMENT-ID> [--from-file|--message] [--visibility-type group|role] [--visibility-value <name>]` CLI subcommand and matching `jira_comment_edit` MCP tool send `PUT /rest/api/3/issue/{key}/comment/{id}` with the supplied JFM rendered to ADF plus optional visibility restriction. New `JiraVisibility` / `JiraVisibilityType` types serialise to JIRA's `{type, identifier}` wire format; `JiraComment` gains an `updated` timestamp field. A shared `parse_comment_input` helper is extracted from the existing `add` subcommand so the two share argument parsing. Covered by wiremock tests for success, 403 forbidden, 404 not-found, visibility payload round-trip, and rejection of unknown visibility types.
- **Resolve Duplicate Amendments in `commit twiddle`** ([#697](https://github.com/rust-works/omni-dev/issues/697)): The model occasionally emits duplicate amendments (same commit hash listed twice), which previously caused the apply path to fail because the first amendment rewrites the commit, leaving subsequent duplicates pointing at a now-nonexistent hash. A new `resolve_duplicate_amendments` step runs immediately after scope refinement in both the single-commit and batch-commit flows: when stdin is a TTY it prompts interactively (showing each candidate message, looping until a valid choice is made), otherwise it silently keeps the first occurrence and emits a warning to stderr. `--auto-apply` always takes the silent path. Order of non-duplicate amendments is preserved. The slice also tightens the system-prompt instructions for amendment cardinality so the duplicates show up less frequently in the first place.
- **Probe Local Server Context Length at Startup** ([#696](https://github.com/rust-works/omni-dev/issues/696)): The `OpenAiAiClient` (used by `USE_OLLAMA=true`, `USE_OPENAI=true`, and LM Studio) now queries the running server's actual loaded context length at client construction and feeds it into `AiClientMetadata`, so token-budget calculations reflect the real-time limits of the model that is actually loaded rather than the static registry estimate. LM Studio is probed via `/api/v0/models`; Ollama is probed via `/api/show`, scanning the response for an architecture-specific `*.context_length` key. `create_default_claude_client` becomes async to accommodate the probe; failures (network error, missing endpoint, unparseable response) fall back to the registry default with a warning. Covered by wiremock tests for both server shapes plus fallback / error paths.
- **YouTube Transcript Subcommand and Source-Agnostic Library Module** ([#687](https://github.com/rust-works/omni-dev/issues/687)): New top-level `omni-dev transcript` command tree fetches captions and metadata from media platforms, launching with full YouTube support. The CLI surface is `transcript youtube fetch|info|list-langs` with `--format srt|vtt|txt|json`, language selection, auto-generated caption opt-in, and translation. The underlying `src/transcript/` library is clap-free and structured around an async `TranscriptSource` trait (`fetch`, `list_languages`, `info`) so future platforms can be added without touching format converters; first-class `Cue`, `Transcript`, `LanguageInfo`, `MediaInfo`, `TrackKind`, `Format` (SRT / WebVTT / plain / JSON), and a `TranscriptError` enum covering invalid locator / parse failure / missing language / auto-caption-opt-in-required / playability refusal / HTTP error live under that module. The YouTube source uses the ANDROID_VR InnerTube client to bypass bot-detection gating that refuses WEB-context sessions on most videos: a per-session `visitorData` token is scraped from the watch-page HTML on first call and cached in `tokio::sync::OnceCell` (concurrent first-callers serialise on a single in-flight fetch rather than double-fetching), then forwarded under `context.client` on every InnerTube `/player` POST. The InnerTube envelope uses ANDROID_VR device-fingerprint fields (`deviceMake`, `deviceModel`, `osName`, `osVersion`, `androidSdkVersion`) and moves the API key from `?key=` to `X-Goog-Api-Key`. URL normalisation accepts watch / share / shorts / embed forms across www / m subdomains plus bare 11-character video IDs; the timedtext URL builder replaces (not appends) `fmt=` and `tlang=` params so YouTube serves `json3` rather than the legacy SRV3 format. Adds `async-trait` to deps. Documentation lives in `docs/transcript.md` (CLI reference, library architecture, error variants, recipe for adding a new source) with README and `docs/README.md` index entries.
- **Layered Model Catalog with User and Project Overrides** ([#684](https://github.com/rust-works/omni-dev/issues/684)): The previously single-source embedded model registry is replaced by a three-layer YAML loader so model specifications and provider configurations can be customised without a rebuild. Precedence (highest wins): explicit `--models-yaml <PATH>` / `OMNI_DEV_MODELS_YAML` env var → `./.omni-dev/models.yaml` (project) → `~/.omni-dev/models.yaml` (user) → `src/templates/models.yaml` (embedded — always present, hard error if malformed). Deep-merge happens at YAML value level: the `models` sequence is keyed by `api_identifier`, the `providers` mapping is deep-merged per provider, other keys use last-writer-wins. A new `ModelSource` enum (`Embedded` / `User` / `Project` / `Override`) is populated by the loader (never read from YAML) and tracked on each merged `ModelSpec` / `ProviderConfig`. `version: "1"` is added to the embedded catalog with advisory mismatch warnings for user / project files declaring a different version. Missing user / project files fall through silently; malformed files log an error and are skipped; an explicit override path that doesn't exist emits a warning. `config models show` renders the merged catalog with per-entry `source:` annotations and a layer-count header; `--embedded-only` falls back to a verbatim embedded dump. Recorded in [ADR-0022](docs/adrs/adr-0022.md), which supersedes [ADR-0011](docs/adrs/adr-0011.md). Covered by recovery / edge-case tests for scalar-replacement of top-level / `models` / `providers` and for empty-env-var filtering.
- **Breaking-Change Detection in Commit-Twiddle System Prompt** ([#744](https://github.com/rust-works/omni-dev/issues/744)): The AI system prompt now contains a mandatory `BREAKING CHANGE DETECTION` section that lists the diff signals which require breaking-change markers (new mandatory parameters, removed or renamed public APIs, CLI flag changes, MCP schema changes, serialisation format changes, default-behaviour changes) and instructs the model to emit **both** the `!` suffix on type/scope and a `BREAKING CHANGE:` footer with concrete migration instructions whenever any signal is detected. An "Additive-Looking-But-Breaking Trap" subsection calls out the case that originally regressed (adding a mandatory `confirm: bool` to an existing MCP params struct without `#[serde(default)]` — addition-of-required-field is breaking even though the type signature looks superset-compatible) with the `WatcherRemoveParams` confirm-field example. A `BREAKING_CHANGE_FINAL_PASS` constant appended to both the basic and contextual user-prompt variants exploits recency bias as a hedge against the system-prompt-only rule being ignored on long inputs. Covered by prompt-assembly tests asserting the new block is present, lists the expected signals, requires both markers, and is inherited into the contextual prompt.

### Changed
- **`omni-dev atlassian jira transition` CLI Restructure (Breaking)** ([#710](https://github.com/rust-works/omni-dev/issues/710)): The flat `transition <KEY> <TRANSITION>` form has been replaced with subcommands. Migrate `omni-dev atlassian jira transition PROJ-1 Done` → `omni-dev atlassian jira transition execute PROJ-1 Done`, and `omni-dev atlassian jira transition PROJ-1 --list` → `omni-dev atlassian jira transition list PROJ-1`. Mirrors the `comment list`/`comment add` shape used elsewhere in the JIRA CLI tree. The MCP `jira_transition` tool is unchanged.
- **Destructive CLI Commands: Confirmation by Default (Breaking)** ([#720](https://github.com/rust-works/omni-dev/issues/720)): `omni-dev atlassian jira watcher remove`, `omni-dev atlassian jira link remove`, and `omni-dev atlassian confluence label remove` now prompt for confirmation by default and accept `--force` to skip the prompt — bringing them into line with the existing behaviour of `jira delete` and `confluence delete`. Previously these three commands executed the API mutation immediately with no guard. Non-interactive callers (CI scripts, automation) must add `--force` to keep current behaviour, or feed `y\n` on stdin.
- **MCP Destructive Tools: Mandatory `confirm: true` (Breaking)** ([#720](https://github.com/rust-works/omni-dev/issues/720)): The `jira_watcher_remove`, `jira_link_remove`, and `confluence_label_remove` MCP tools now require a mandatory `confirm: bool` parameter and refuse with an explanatory error when called without `confirm: true`. Brings them into line with the existing `jira_delete` and `confluence_delete` tools. The shared `WatcherMutateParams` is split: the `add` tool keeps the original two-field struct, the `remove` tool gets a new `WatcherRemoveParams` with the `confirm` field. `LinkRemoveParams` and `ConfluenceLabelRemoveParams` gain `confirm` in place. There is no `dry_run` parameter on the MCP surface — assistants can preview by reading the relevant resource (`jira_read`, `confluence_read`, `jira_watcher_list`, `jira_link_list`) before mutating.
- **`sha2` 0.10 → 0.11** ([#757](https://github.com/rust-works/omni-dev/pull/757)): Dependabot bump. `sha2` 0.11 changes the digest output type from `GenericArray` (which implements `LowerHex`) to `hybrid_array::Array` (which does not), breaking the previous `format!("{:x}", Sha256::digest(...))` idiom at three call sites in `src/atlassian/adf_schema/drift.rs` and `src/bin/adf_schema_codegen.rs`. A new `pub fn hex_encode(bytes: &[u8]) -> String` helper in `drift.rs` folds bytes into a lowercase hex string and replaces all three sites. Transitive bumps: `block-buffer` 0.10→0.12, `cpufeatures` 0.2→0.3, `crypto-common` 0.1→0.2, `digest` 0.10→0.11; adds `hybrid-array` 0.4 and `const-oid` 0.10; removes `generic-array` 0.14.
- **`similar` 2.7 → 3.1** ([#758](https://github.com/rust-works/omni-dev/pull/758)): Dependabot bump. No call-site changes required.
- **`tokio` 1.52.1 → 1.52.3** ([#756](https://github.com/rust-works/omni-dev/pull/756)): Dependabot bump. No call-site changes required.
- **Subject-Length Rule Replaced With Imperative-Mood in Commit Examples**: The 72-character subject-line limit was documented in `commit-guidelines.md` and `default-commit-guidelines.md` but never enforced by the checker, while the `imperative-mood` rule was checked but absent from the human-readable docs. The mismatch is removed: the length limit is dropped from both guideline files and the imperative-mood rule replaces it in the prompt example output and test fixtures (`prompts.rs`, `client.rs`, `check.rs`).

### Fixed
- **`decisionItem` ADF Inline Content** ([#753](https://github.com/rust-works/omni-dev/issues/753)): The ADF schema requires `decisionItem` to contain inline nodes (`text`, etc.) directly, not wrapped in a `paragraph`. `parse_decision_items` was inserting a paragraph wrapper before passing inline content to `AdfNode::decision_item`, producing schema-invalid output. The wrapper is removed and a regression test asserts the first child of a constructed `decisionItem` is a `text` node, not a `paragraph`.
- **`claude-cli` `--json-schema` Inline Argument**: `claude -p --json-schema` silently returns empty output when given a filesystem path; the value must be an inline JSON string on argv. `build_command_with_schema` is changed from `Option<&Path>` to `Option<&str>` and `run_with_options` now serialises the schema with `serde_json::to_string` and passes it verbatim as the argument instead of writing a temp file and passing the path. A new `build_command_inline_schema_is_passed_verbatim_not_as_path` test asserts the argv value starts with `{` and is not an absolute path; an integration test using a new argv-capture shim asserts the inline JSON appears verbatim in the subprocess argv.
- **Multi-Scope Subject Allows Single Trailing Space After Comma**: Pre-validation previously rejected `feat(a, b): …` (one space after the comma) and only accepted `feat(a,b): …`. The check is relaxed to permit a single trailing space (`!scope.contains(",  ") && !scope.contains(" ,")`) while still rejecting two or more spaces after the comma and any whitespace before the comma. `commit-guidelines.md` now shows both `scope1,scope2` and `scope1, scope2` as accepted forms and explicitly calls out the rejected variants.
- **Breaking-Change Detection: Additive-Looking-But-Breaking Trap** ([#744](https://github.com/rust-works/omni-dev/issues/744)): Companion to the [#744](https://github.com/rust-works/omni-dev/issues/744) feature entry above — adds the `WatcherRemoveParams` example and the diff-signal expansion that catches new mandatory MCP params, new mandatory struct fields without `#[serde(default)]`, and new confirmation prompts on previously-unattended operations as breaking even when the type signature looks superset-compatible.

### Documentation
- **Comprehensive Documentation Coverage Refresh**: Audited the user-facing docs against the current CLI/MCP surface and closed the major gaps that had accumulated through the v0.23–v0.25 cycle. New `docs/mcp.md` is the canonical MCP tool/resource reference (~70 tools across git, JIRA, Confluence, Atlassian shared, Datadog, AI/config domains plus the `omni-dev://specs/{name}` resource scheme), and the README MCP section is rewritten to defer detail there. The README Datadog section drops "subsequent slices" wording in favour of present-tense subcommand examples, and a new `## Datadog Integration` section in `docs/user-guide.md` covers auth, metrics, monitors, dashboards, logs, events, SLOs, hosts, and downtimes. The user guide also gains backfills for JIRA `read --fields`/`--all-fields`, `write --parent`/`--assignee`/`--reporter`/`--no-content`/`--set-field`, `create --set-field`, `sprint create`/`update`, watcher, worklog, user search, and dev-info subcommands; Confluence comments, labels, children, user search, and bulk download (with `--space`/`--title-filter`/`--resume`/`--on-conflict`/`--concurrency`); `git branch create pr` flag table (adds `--ready`/`--draft`/`--base`/`--model`/`--context-dir`/`--no-push`); a full `git commit message check` reference; and new `ai chat` / `ai claude history sync` / `ai claude skills` / `ai claude cli model resolve` / `commands generate` sections. `docs/configuration.md` gains an "AI Backend Selection" matrix covering the five-way dispatch (`OMNI_DEV_AI_BACKEND` claude-cli → Ollama → OpenAI → Bedrock → Anthropic), model resolution precedence, and the claude-cli sandbox/escape-hatch/budget-cap envelope. `docs/troubleshooting.md` grows new sections for Atlassian auth (404, trailing slashes, MCP env inheritance), Datadog auth (region/site mismatch, 429), MCP server (`failed to open git repository`, missing `mcp` feature), and `claude-cli` backend failures (tools blocked, MCP blocked, budget cap). `ARCHITECTURE.md` module map adds `mcp/`, `atlassian/`, `datadog/`, `claude/ai/claude_cli.rs`, the `omni-dev-mcp` second binary (per ADR-0021), and an "AI backend dispatch" subsection. Drift fixes: removed the non-existent `--edit` flag from twiddle's option tables in `README.md` and `docs/user-guide.md`; bumped the Rust MSRV claim from 1.70+ to 1.80+ to match `Cargo.toml`. `docs/README.md` Key Features table adds rows for Datadog and the MCP server; `CONTRIBUTING.md` gains the `.work/` worktree convention.
- **ADF Content Model Section in JFM Specification** ([#716](https://github.com/rust-works/omni-dev/issues/716)): A new "Content Model Constraints" section in `docs/specs/jfm.md` documents the public ADF validator helpers (`allowed_children`, `permits_child`, `validate_document`, `content_model`), the common per-container pitfalls and recommended workarounds (expand↔panel, nested-expand in table cells, decision / task items, blockquote / list-item containment, layoutSection nesting), forward-compatibility behaviour on unknown and `unsupported*` node types, and the write-path enforcement path via `ValidatedAdfDocument` plus HTTP-500 re-diagnosis via `AtlassianError::ApiRequestFailedWithDiagnosis`. The "Coverage and limits" subsection lists what the validator currently covers (allowed-children sets, per-term quantifiers) and what remains out of scope (mark whitelists and attribute-value schemas — the [#733](https://github.com/rust-works/omni-dev/issues/733) follow-ups).
- **Architecture Decision Records**:
  - [ADR-0022](docs/adrs/adr-0022.md) accepted — layered model catalog with user and project overrides, supersedes [ADR-0011](docs/adrs/adr-0011.md).
  - [ADR-0023](docs/adrs/adr-0023.md) accepted — data-driven ADF content-model schema and validator transcribed from the upstream JSON schema.
  - [ADR-0025](docs/adrs/adr-0025.md) accepted — wire ADF schema validator into the API send path via `ValidatedAdfDocument` newtype enforcement.
  - [ADR-0026](docs/adrs/adr-0026.md) accepted — ADF validator extensions covering quantifier / arity checks, per-node attribute schemas, and per-context mark allow-lists.

### CI/CD
- **`cargo clippy --all-targets` in Lint Workflow** ([#690](https://github.com/rust-works/omni-dev/issues/690)): The clippy step in `.github/workflows/ci.yml` now passes `--all-targets`, surfacing lints on test / bench / example targets that were previously checked only for the default target set. The slice also includes batch lint fixes across `src/atlassian/` produced when `--all-targets` first surfaced them, plus `#[allow(clippy::unwrap_used, clippy::expect_used)]` opt-ins in test modules where assertion-style panics are idiomatic.
- **`rustfmt` Component Pinned in Rust Toolchain Setup**: The Rust toolchain setup action in CI now explicitly installs the `rustfmt` component so `cargo fmt --check` runs reliably in environments where the default profile does not include it.

## [0.25.0] - 2026-05-05

### Added
- **Set JIRA Parent Field via `jira write` and `jira_link`** ([#670](https://github.com/rust-works/omni-dev/issues/670)): Closes the gap that previously forced callers to fall back to raw `curl` for setting the JIRA `parent` field. `omni-dev jira write` accepts a new `--parent <KEY>` flag (independent of `--set-field`, which only handles custom fields); when supplied alone it performs a parent-only update without overwriting the existing description, when supplied with a body it sends both in one PUT, and the parent key is validated up-front via `validate_issue_key`. The MCP `jira_write` tool gains a matching `parent` parameter and makes `content` optional — at least one of `content`/`parent` is required. The MCP `jira_link` tool gains a `parent` action (`key` = child issue, `target` = parent issue) for callers that prefer the link-management surface; this is distinct from `create`, which produces relationship links (Blocks, Composition, etc.) rather than the system parent field. Internally, `AtlassianClient::link_to_epic(epic_key, issue_key)` was renamed to `set_issue_parent(issue_key, parent_key)` (argument order flipped to match other update helpers); the CLI `jira link epic` subcommand is unchanged for back-compat. `update_issue_with_custom_fields` now accepts `description_adf: Option<&AdfDocument>` and a new `parent: Option<&str>` so a parent-only PUT does not overwrite the description, with a guard rejecting empty payloads. Implemented across `src/atlassian/client.rs`, `src/cli/atlassian/helpers.rs`, `src/cli/atlassian/jira/{write.rs,link.rs,mod.rs}`, and `src/mcp/jira_core_tools.rs`. Covered by new wiremock-backed tests for `set_issue_parent`, parent-only updates, content+parent updates, the `--parent` CLI flag (dry-run, parent-only, body+parent, invalid-key rejection), the `jira_link` `parent` action (success, missing-key, missing-target, API error), and the `jira_write` MCP tool's content/parent variants.
- **`jira_write` Field Updates** ([#669](https://github.com/rust-works/omni-dev/issues/669)): The `jira_write` MCP tool and `omni-dev atlassian jira write` CLI now accept typed `assignee` and `reporter` parameters (taking an Atlassian `accountId`) plus an escape-hatch `fields` map for arbitrary canonical JIRA fields. The empty string `""` clears assignee/reporter (Atlassian's `null` payload); `"-1"` triggers automatic assignment. The description body is now optional — `content`/`--no-content` lets a caller flip an assignee or set a priority without re-posting the description, removing the previous `jira_read` → `jira_write` round-trip. A typed `assignee`/`reporter` parameter that collides with the same key inside `fields` (or `--set-field`) is rejected with a hard error rather than silently overriding, so the caller's intent is unambiguous. Implemented in `src/mcp/jira_core_tools.rs`, `src/cli/atlassian/jira/write.rs`, and a shared `user_field_value` / `apply_user_field_overrides` helper in `src/atlassian/custom_fields.rs` (used by both MCP and CLI paths).
- **`jira_user_search` MCP Tool & CLI** ([#669](https://github.com/rust-works/omni-dev/issues/669)): New `jira_user_search` MCP tool and `omni-dev atlassian jira user search` CLI subcommand resolve a display name or email substring to an Atlassian `accountId` so callers can populate `jira_write`'s new `assignee`/`reporter` parameters. Returns YAML/table/json/yaml/jsonl output with `account_id`, `display_name`, `email_address` (often GDPR-redacted), `active`, and `account_type` for each match. The MCP tool description explicitly tells the model to call this tool first when only a name or email is available, keeping disambiguation visible to the agent rather than hidden inside `jira_write`. Backed by a new `AtlassianClient::search_jira_users` method that paginates `GET /rest/api/3/user/search` until a short page is returned (the endpoint has no `isLast`/`next` envelope).
- **`omni-dev://specs/{name}` MCP Resource** ([#672](https://github.com/rust-works/omni-dev/issues/672)): New MCP resource URI scheme serves reference specifications embedded into the binary at compile time. The initial spec (`omni-dev://specs/jfm`) is the JIRA-Flavoured Markdown reference, embedded from `docs/specs/jfm.md` via `include_str!` so installed builds can serve it without reading from disk and the resource cannot drift from the human-readable docs. The resource template is advertised through the server's `resources` capability with a description guiding AI clients to fetch it before writing JIRA or Confluence content; server instructions and the `jira_write` tool description point at the same resource. `content` field doc comments on `ConfluenceCreateParams`, `ConfluenceWriteParams`, `JiraCreateParams`, `JiraWriteParams`, and `JiraCommentParams` reference the spec resource so the model surfaces it during schema introspection. New `ResourceUri::Specs` variant adds `EmptyIdentifier` and `Malformed` parsing errors. Implemented in `src/mcp/specs.rs`, `src/mcp/resources.rs`, and `src/mcp/server.rs`; covered by new unit tests for spec lookup, URI parsing, and `read_resource` dispatch, plus integration tests for listing and reading the resource.

### Changed
- **`jira_transition` MCP Tool Discoverability** ([#671](https://github.com/rust-works/omni-dev/issues/671)): The `jira_transition` tool description now leads with the most common usage (executing by name, e.g. `transition: "In Progress"`), shows the numeric-id form (`transition: "31"`), and explicitly tells the assistant to call with `list = true` first when the available transitions are not yet known. The `transition` field doc carries the same examples into the JSON schema. When the underlying `POST /rest/api/3/issue/{key}/transitions` call fails, the error chain now includes a hint that the workflow may require additional fields (assignee, resolution, screen-driven field) or that the transition may not be valid from the current status, suggesting `list = true` to confirm — the original `AtlassianError::ApiRequestFailed { status, body }` stays in the chain so the HTTP status and response body remain visible. No API surface change.
- **rmcp 1.5.0 → 1.6.0**: Bumped the `rmcp` dependency (and `rmcp-macros`) to the upstream 1.6.0 release.

### Documentation
- **JFM Markdown Description in Confluence Tool Annotations**: Clarified the JFM markdown wording in the `confluence_*` MCP tool descriptions so the model surfaces the correct format expectations.
- **ADR-0021 Accepted**: Marked the "MCP server via second binary" architectural decision as accepted.

### CI/CD
- **Stop Hook Enforces Snapshot Updates** ([#667](https://github.com/rust-works/omni-dev/issues/667)): Added a Claude Code stop hook (`.claude/hooks/check-snapshots.sh`) that blocks session completion when files under `src/cli/` or `src/main.rs` have changed but `tests/snapshots/` has not been updated, directing the AI to run the `update-snapshots` skill before stopping. Guards against infinite loops via the `stop_hook_active` flag, registered with a 30-second timeout in `.claude/settings.json`. Permissions also broadened to allow all `omni_dev` debug/release binaries instead of a single hardcoded hash-suffixed path.

## [0.24.0] - 2026-05-03

### Added
- **Claude History Sync — Markdown Output** ([#665](https://github.com/rust-works/omni-dev/issues/665)): `omni-dev ai claude history sync` accepts `--output-format <jsonl|markdown>` (comma-separated, e.g. `--output-format jsonl,markdown` writes both side-by-side). Markdown output produces an LLM-friendly `<target>/<slug>/<uuid>.md` alongside (or instead of) the lossless `.jsonl`, with YAML frontmatter (session metadata) followed by `## User` / `## Assistant` turns, `### Tool call: <name>` blocks for tool invocations, `<details>` blocks for thinking, and 4-backtick fences when tool output contains embedded triple-backtick blocks. Agent-to-user interactions are surfaced as first-class structured events: `AskUserQuestion` calls render as `### Agent question: <header>` with the question text and option list (with descriptions and a `(multi-select)` marker where applicable), and the paired answer renders as `## User response`; tool denials are detected via the "The user doesn't want to proceed" sentinel and labelled `denied by user` rather than a generic `error`; user interrupts (escape mid-execution) are labelled `interrupted by user`. This means the rendered transcript distinguishes "the agent asked, the user picked B" and "the agent tried X, the user denied" from plain tool runs — the signal a coaching LLM needs. Sub-agent (`Agent`) calls render only the `prompt` argument; sub-agent internal turns are not captured (matches the v1 sync invariant from #658). The existing `<persisted-output>` "(persisted, NN KB)" envelope from large tool outputs is preserved verbatim. System-side events (system reminders inside user text, attachments, permission-mode changes, summary events, generic system events) are **included by default** — pass `--exclude-system` to drop them; `--exclude-system` only affects markdown output, the jsonl is byte-identical regardless. Markdown idempotency uses source mtime alone (the rendered length differs from the source length, so size cannot participate in the freshness key); the source jsonl is append-only, making mtime alone sufficient. `--prune` scopes deletion to whichever extensions are listed in `--output-format`, so artifacts the run was not asked to manage survive. Implemented in `src/cli/ai/claude/history/markdown.rs` (renderer) with new clap surface in `src/cli/ai/claude/history/sync.rs` and a `FileFormat` enum in `src/cli/ai/claude/history/common.rs`. Covered by 130+ unit tests in the history module including `insta` snapshots pinning the rendered shape of one of each event type both with and without `--exclude-system`, plus end-to-end tests for both-formats-side-by-side, prune scoping per format, partial-jsonl-prefix tolerance, and markdown idempotency on re-run.
- **Claude History Sync** ([#658](https://github.com/rust-works/omni-dev/issues/658)): New `omni-dev ai claude history sync --target <DIR>` exports Claude Code conversation history to a target directory as one `.jsonl` per chat, grouped by encoded project slug (`<target>/<slug>/<uuid>.jsonl`). Re-running is idempotent — sessions whose source `(size, mtime)` match the target are skipped, modified sessions are overwritten via a sibling tempfile + rename, and source `mtime` is preserved on the target so downstream tooling can sort sessions chronologically. In-progress chats produce a valid jsonl prefix via a snapshot-EOF read (the source size is captured up front and exactly that many bytes are copied — never more). Flags: `--source` (defaults to `~/.claude/projects`), `--project NAME_OR_PATH` (matches encoded slug or decoded cwd path), `--since DURATION_OR_DATE` (`30s`, `5m`, `2h`, `7d`, `4w`, or RFC 3339), `--prune` (deletes target files for sessions removed upstream — only files matching `<slug>/<uuid>.jsonl` are eligible; anything else inside the target survives regardless), `--dry-run`, and `--format text|yaml`. Refuses to run when the target is the source root or a descendant. The export is a **behavioural transcript** — prompts, responses, thinking, tool calls, and tool-result metadata sufficient for analyst use cases (behavioural coaching, work-log generation). Sub-agent internal turns, tool-result `*.txt` sidecars, PDF rasters, and auto-memory are deliberately excluded; see the issue for the rationale and planned follow-ups (memory sync, full-fidelity archive mode, restore, redact, MCP wrapper). Implemented in `src/cli/ai/claude/history/{mod.rs, common.rs, sync.rs}` and wired through `src/cli/ai/claude/mod.rs`. Covered by 48 unit tests (line coverage 95–100% across the new module).
- **`--claude-cli-allow-mcp` Escape Hatch** ([#634](https://github.com/rust-works/omni-dev/issues/634)): New global flag and `OMNI_DEV_CLAUDE_CLI_ALLOW_MCP` environment variable opt the `claude-cli` backend out of `--strict-mcp-config`, letting the nested `claude -p` session load MCP servers from `~/.claude/settings.json`. Independent of `--claude-cli-allow-tools` so MCP access can be granted without enabling built-in tools, and vice-versa. A WARN log fires on every invocation when the flag is active, mirroring the existing tool escape hatch. Wired through `src/cli.rs` (flag → env propagation) and `src/claude/ai/claude_cli.rs` (`ClaudeCliAiClient::with_allow_mcp` builder, `allow_mcp_from_env`, conditional argv assembly). Honours the README forward reference promised by the [#608](https://github.com/rust-works/omni-dev/issues/608) lockdown work.
- **MCP `output_file` for Read Tools** ([#631](https://github.com/rust-works/omni-dev/issues/631)): `confluence_read` and `jira_read` accept an optional `output_file` parameter. When set, the rendered content is written to that path and the tool returns a short YAML summary (`path`, `bytes`, `format`) instead of the inline body. This avoids blowing past the assistant's context window on large pages — the assistant can then page through the file with offset/limit using its filesystem read tool. Mirrors the on-disk pattern already established by `confluence_download` and `jira_attachment_download`. Implemented in `src/mcp/output_file.rs` and wired through `confluence_tools::run_confluence_read` and `jira_core_tools::run_jira_read`.
- **Datadog Phase 2 Endpoints** ([#639](https://github.com/rust-works/omni-dev/issues/639)): New `omni-dev datadog events`, `slo`, `hosts`, `downtime`, and `metrics catalog` subcommands wrap the read-only Phase 2 Datadog endpoints called out in the original [#619](https://github.com/rust-works/omni-dev/issues/619) design. `events list` calls `GET /api/v2/events` (single-page; cursor pagination preserved on `meta.page.after` for callers that need to iterate manually); `slo list` and `slo get <id>` call `GET /api/v1/slo` (auto-paginating, capped at 10000 SLOs) and `GET /api/v1/slo/{id}`; `hosts list` calls `GET /api/v1/hosts` with `start`/`count` pagination; `downtime list [--active-only]` calls `GET /api/v1/downtime` (the API returns the full set in one response — no pagination); `metrics catalog list` calls `GET /api/v1/metrics` (distinct from the Phase 1 metrics *query* endpoint at `/api/v1/query`). Built on five new façades — `EventsApi`, `SloApi`, `HostsApi`, `DowntimesApi`, `MetricsCatalogApi` — under `src/datadog/` plus matching wire types (`Event`, `EventsResponse`, `Slo`, `SloListResponse`, `SloGetResponse`, `Host`, `HostsResponse`, `Downtime`, `MetricCatalogResponse`) in `src/datadog/types.rs`. Output supports `-o json|yaml|yamls|jsonl|table`; bespoke tables render `TIMESTAMP | TITLE | SOURCE | HOST | TAGS` (events), `ID | NAME | TYPE | TAGS` (SLOs), `NAME | UP | LAST REPORTED | APPS` (hosts), `ID | SCOPE | START | END | MONITOR | MESSAGE` (downtimes), and `METRIC` (metrics catalog). Six new MCP tools (`datadog_events_list`, `datadog_slo_list`, `datadog_slo_get`, `datadog_hosts_list`, `datadog_downtime_list`, `datadog_metrics_catalog_list`) mirror the CLI surface so AI assistants can issue the same queries over the MCP transport. No new crate dependencies. Phase 2 follow-ons (logs cursor pagination, 429 retry tuning) remain deferred.
- **Datadog MCP Tools** ([#640](https://github.com/rust-works/omni-dev/issues/640)): The Phase 1 Datadog CLI surface is now also exposed over MCP so AI assistants (Claude Desktop, Claude Code) can invoke Datadog read-only queries over stdio. New tools registered on `omni-dev-mcp`: `datadog_auth_status` (boolean credential-presence flags only — never emits `DATADOG_API_KEY` or `DATADOG_APP_KEY` values), `datadog_metrics_query`, `datadog_monitor_list`, `datadog_monitor_get`, `datadog_monitor_search`, `datadog_dashboard_list`, `datadog_dashboard_get`, and `datadog_logs_search`. Each tool builds a fresh `DatadogClient` per invocation via the existing `cli::datadog::helpers::create_client` (per-call construction mirrors the Atlassian tools and lets credential changes take effect without restarting the MCP server) and serialises the typed response struct as YAML, matching the CLI `-o yaml` output. Implemented in `src/mcp/datadog_tools.rs` and registered through `Self::datadog_tool_router()` in `OmniDevServer::new()`. Gated behind the existing `mcp` Cargo feature; non-MCP builds are unaffected. No new crate dependencies.
- **Datadog Logs Search** ([#638](https://github.com/rust-works/omni-dev/issues/638)): New `omni-dev datadog logs search` subcommand wraps Datadog's read-only logs search endpoint via `POST /api/v2/logs/events/search` (the only Phase 1 endpoint that uses POST). Accepts `--filter <q>`, `--from` (relative shorthand like `15m`/`1h`, `now`, RFC 3339, or Unix epoch seconds — converted to RFC 3339 before sending), `--to` (default `now`), `--limit` (per-page; default 100, max 1000 — rejected client-side above the cap), and `--sort timestamp-asc|timestamp-desc` (serialised as `timestamp` / `-timestamp` on the wire). Built on a new `LogsApi` façade in `src/datadog/logs_api.rs` plus `LogEvent`, `LogEventAttributes`, `LogSearchResult`, `LogSearchMeta`, `LogSearchPage`, and `SortOrder` types in `src/datadog/types.rs`. Datadog v2 logs search uses cursor pagination (`meta.page.after`), not offset; Phase 1 ships single-page only and the cursor token is preserved on the response so a Phase 2 follow-up can iterate without changing the wire types. Output supports `-o json|yaml|yamls|jsonl|table`; the bespoke table renders `TIMESTAMP | SERVICE | STATUS | MESSAGE`. No new crate dependencies. Closes [#619](https://github.com/rust-works/omni-dev/issues/619).
- **Datadog Dashboard List/Get** ([#637](https://github.com/rust-works/omni-dev/issues/637)): New `omni-dev datadog dashboard` subcommands wrap Datadog's read-only dashboard endpoints. `dashboard list [--filter-shared]` calls `GET /api/v1/dashboard` (which returns every dashboard in a single response — no server-side pagination); `dashboard get <id>` calls `GET /api/v1/dashboard/{id}` and renders the full definition. Built on a new `DashboardsApi` façade in `src/datadog/dashboards_api.rs` plus `DashboardSummary`, `DashboardListResponse`, and `Dashboard` types in `src/datadog/types.rs`. Per-widget schemas are deeply heterogeneous, so `Dashboard.widgets` is preserved as raw `serde_json::Value` (mirroring how ADF is handled in the Atlassian integration). Output supports `-o json|yaml|yamls|jsonl|table`; the bespoke table renders `ID | TITLE | AUTHOR | URL`. No new crate dependencies.
- **Datadog Monitor List/Get/Search** ([#636](https://github.com/rust-works/omni-dev/issues/636)): New `omni-dev datadog monitor` subcommands wrap Datadog's read-only monitor endpoints. `monitor list [--name <substr>] [--tags k:v,...] [--monitor-tags k:v,...] [--limit N]` filters via `GET /api/v1/monitor`; `monitor get <id>` fetches a single monitor; `monitor search --query <str> [--limit N]` runs the faceted `GET /api/v1/monitor/search`. `--limit 0` auto-paginates and is hard-capped at 10,000 monitors per invocation (per the decisions in #619). Built on a new `MonitorsApi` façade in `src/datadog/monitors_api.rs` plus `Monitor`, `MonitorSearchResult`, `MonitorSearchItem`, and `MonitorSearchMetadata` types in `src/datadog/types.rs`. Output supports `-o json|yaml|yamls|jsonl|table`; the bespoke table renders `ID | NAME | STATUS | TAGS`. No new crate dependencies.
- **Datadog Metrics Query** ([#635](https://github.com/rust-works/omni-dev/issues/635)): New `omni-dev datadog metrics query` subcommand runs point-in-time Datadog timeseries queries via `GET /api/v1/query`. Accepts `--query`, `--from`, and optional `--to` (relative shorthand like `15m`/`1h`, the literal `now`, RFC 3339 timestamps, or Unix epoch seconds via the shared `src/datadog/time.rs` parser), plus `-o json|yaml|yamls|jsonl|table`. Table output is bespoke: a `TIMESTAMP` column followed by one column per series, with the union of per-series timestamps sorted ascending and `-` rendered for gaps and missing samples. Built on a new `MetricsApi` façade in `src/datadog/metrics_api.rs` that percent-encodes the query string via the existing `url` crate. No new crate dependencies.
- **Datadog Integration — Scaffold & Auth** ([#619](https://github.com/rust-works/omni-dev/issues/619)): New `omni-dev datadog` command tree exposing read-only Datadog API access. This first slice ships the authentication surface: `datadog auth login` (interactive credential prompt), `datadog auth logout` (removes credentials from `~/.omni-dev/settings.json`), and `datadog auth status` (verifies credentials via `/api/v1/validate`). Credentials live in the shared `env` map under `DATADOG_API_KEY`, `DATADOG_APP_KEY`, and `DATADOG_SITE`; environment variables override stored settings. The underlying `DatadogClient` in `src/datadog/client.rs` handles 429 responses with `Retry-After` and Datadog-specific `X-RateLimit-Reset` awareness, and surfaces `X-RateLimit-*` headers in error output when retries are exhausted. No new crate dependencies.

## [0.23.1] - 2026-04-23

### Fixed
- **AI Issue Output Field Order** ([#627](https://github.com/rust-works/omni-dev/issues/627)): Require the `reasoning` field to appear before `severity` in AI-generated issue output. The prompt now instructs the model to write `reasoning` before `severity`, and the deserializer rejects payloads whose field order is reversed so that callers see a clear parse error rather than silently accepting malformed output
- **Multi-Scope Whitespace Trimming** ([#626](https://github.com/rust-works/omni-dev/issues/626)): `feat(a, b): …` style multi-scope subjects are now valid. Scope validation trims whitespace around each comma-separated part before checking allowed scopes, so spaces after commas no longer cause spurious validation failures

### Security
- **RUSTSEC-2026-0104** ([#623](https://github.com/rust-works/omni-dev/pull/623)): Bump `rustls-webpki` to 0.103.13 to address RUSTSEC-2026-0104

### Documentation
- **Worktree Convention** ([#622](https://github.com/rust-works/omni-dev/pull/622)): Document the project convention that new git worktrees live under `.work/` (gitignored) so worktrees stay scoped to the project rather than scattered across sibling directories

## [0.23.0] - 2026-04-22

### Added
- **MCP Server (Foundation)** ([#575](https://github.com/rust-works/omni-dev/issues/575)): New `omni-dev-mcp` binary exposes omni-dev's git analysis as MCP tools for AI assistants (Claude Desktop, Claude Code). Gated behind the `mcp` Cargo feature so default builds are unaffected. Initial tool: `git_view_commits`. See [ADR-0021](docs/adrs/adr-0021.md) for the architectural rationale.
- **MCP Resource System** ([#606](https://github.com/rust-works/omni-dev/issues/606)): Content is now addressable over MCP via three URI schemes — `git://repo/commits/{range}`, `jira://issue/{key}[.adf]`, and `confluence://page/{id}[.adf]` — so AI clients can fetch commits, JIRA issues, and Confluence pages as MCP resources without issuing tool calls. Resource templates, listings, and reads are advertised through the server's `resources` capability. JIRA and Confluence resources return JFM markdown by default or raw ADF JSON when the URI ends in `.adf`. See `STYLE-0026` in [docs/STYLE_GUIDE.md](docs/STYLE_GUIDE.md) for MCP tool/resource authoring conventions.
- **JIRA Custom Field Read** ([#594](https://github.com/rust-works/omni-dev/issues/594)): `jira read` accepts `--fields <name>` (repeatable) and `--all-fields` to request custom fields alongside the default set. Scalar custom fields are rendered into the frontmatter `custom_fields:` map; ADF rich-text custom fields are rendered as tagged body sections (`<!-- field: Name (id) -->`) in the JFM document
- **JIRA Custom Field Write** ([#594](https://github.com/rust-works/omni-dev/issues/594)): `jira write` and `jira create` now support writing custom fields. Frontmatter `custom_fields:` entries and body sections delimited by `<!-- field: Name (id) -->` are resolved through `/editmeta` (write) and `/createmeta` (create), dispatching by schema type (option, radio, array, textfield, number, date, and rich-text ADF). A new `--set-field NAME=VALUE` CLI flag allows inline overrides; CLI values take precedence over frontmatter scalars for the same name. Rejected when combined with `--format adf`
- **MCP Tool: `git_branch_info`** ([#600](https://github.com/rust-works/omni-dev/issues/600)): Mirrors `omni-dev git branch info`. Returns repository information as YAML for commits between a base branch and `HEAD`.
- **MCP Tool: `git_check_commits`** ([#600](https://github.com/rust-works/omni-dev/issues/600)): Mirrors `omni-dev git commit message check`. Returns the full check report plus pass/fail summary and exit code (honouring `strict`) as a structured payload so the assistant can act on validation failures without parsing exit codes.
- **MCP Tool: `git_twiddle_commits`** ([#600](https://github.com/rust-works/omni-dev/issues/600)): Mirrors `omni-dev git commit message twiddle --auto-apply`. Forces non-interactive semantics — never starts an editor. Accepts a `dry_run` flag that returns the proposed amendments as YAML without applying them.
- **MCP Tool: `git_create_pr`** ([#600](https://github.com/rust-works/omni-dev/issues/600)): Mirrors the content-generation phase of `omni-dev git branch create pr`. Returns the AI-drafted PR title and description as YAML; does not push the branch or invoke `gh pr create`.
- **MCP JIRA Sprint Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_sprint_list`, `jira_sprint_issues`, `jira_sprint_add`, `jira_sprint_create`, and `jira_sprint_update` — list, inspect, populate, create, and transition agile sprints from MCP-aware AI assistants
- **MCP JIRA Watcher Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_watcher_list`, `jira_watcher_add`, `jira_watcher_remove` — manage watchers on a JIRA issue by Atlassian account ID
- **MCP JIRA Worklog Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_worklog_list` and `jira_worklog_add` — list worklog entries and log time on an issue (accepts JIRA's `1h 30m` duration format)
- **MCP JIRA Field Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_field_list` (with optional substring filter) and `jira_field_options` (auto-discovers context when not specified) — discover custom fields and their permitted option values
- **MCP JIRA Board Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_board_list` and `jira_board_issues` — enumerate agile boards and their issues, with optional project/type/JQL filters
- **MCP JIRA Attachment Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_attachment_download` (filename substring filter) and `jira_attachment_images` (PNG/JPEG/GIF/SVG/WebP only) — download attachments to disk and return YAML metadata including the on-disk path; defaults to a fresh temp dir so the assistant can read files via its filesystem tool
- **MCP JIRA Project & Changelog Tools** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_project_list` and `jira_changelog` — enumerate projects and inspect issue change history
- **MCP JIRA Delete Tool (Destructive)** ([#602](https://github.com/rust-works/omni-dev/issues/602)): `jira_delete` deletes an issue irreversibly. The tool requires the assistant to explicitly pass `confirm: true`; without it, the call is rejected before any API contact. The required-confirmation guard was preferred over a Cargo feature flag to keep the MCP build surface uniform while still preventing accidental deletions through MCP.
- **MCP JIRA Tools — Read/Search** ([#601](https://github.com/rust-works/omni-dev/issues/601)): `jira_read` fetches an issue as JFM markdown (default) or raw ADF JSON; `jira_search` runs a JQL query and returns matching issues as YAML.
- **MCP JIRA Tools — Create/Write** ([#601](https://github.com/rust-works/omni-dev/issues/601)): `jira_create` creates a new JIRA issue from `project`/`summary`/`description`/`issue_type`; `jira_write` updates an existing issue's description from JFM markdown or raw ADF.
- **MCP JIRA Tools — Transition/Comment** ([#601](https://github.com/rust-works/omni-dev/issues/601)): `jira_transition` lists workflow transitions (or executes one by name/id with an optional comment); `jira_comment` lists or posts comments on a JIRA issue.
- **MCP JIRA Tools — Link/Dev** ([#601](https://github.com/rust-works/omni-dev/issues/601)): `jira_link` lists issue links, lists available link types, creates, or removes links; `jira_dev` returns linked pull requests, branches, and repositories as YAML.
- **MCP Confluence Tools** ([#603](https://github.com/rust-works/omni-dev/issues/603)): Six Confluence tools wired through the MCP server — `confluence_read`, `confluence_search`, `confluence_create`, `confluence_write`, `confluence_delete`, and `confluence_download`. Each mirrors its CLI counterpart and reuses the same `AtlassianClient` / `ConfluenceApi` implementation. `confluence_delete` requires an explicit `confirm: true` parameter to prevent accidental deletion; `confluence_download` writes page trees to a caller-provided directory (or a tempdir) and returns a YAML manifest summary.
- **MCP `atlassian_convert` Tool** ([#603](https://github.com/rust-works/omni-dev/issues/603)): Stateless JFM ↔ ADF conversion tool exposed over MCP. Takes `content` and `direction` (`"to-adf"` or `"from-adf"`) plus optional `compact` / `strip_local_ids` flags. No API client required.
- **MCP Confluence Children Tool** ([#604](https://github.com/rust-works/omni-dev/issues/604)): `confluence_children` MCP tool lists child pages of a Confluence page or top-level pages in a space, with optional `recursive` and `max_depth` parameters mirroring the `atlassian confluence children` CLI command
- **MCP Confluence Comment Tools** ([#604](https://github.com/rust-works/omni-dev/issues/604)): `confluence_comment_list` (auto-paginated, with a `limit` parameter where `0` means unlimited) and `confluence_comment_add` (markdown body, converted to ADF before posting) MCP tools mirror the `atlassian confluence comment` CLI subcommands
- **MCP Confluence Label Tools** ([#604](https://github.com/rust-works/omni-dev/issues/604)): `confluence_label_list`, `confluence_label_add`, and `confluence_label_remove` MCP tools mirror the `atlassian confluence label` CLI subcommands
- **MCP Confluence User Search Tool** ([#604](https://github.com/rust-works/omni-dev/issues/604)): `confluence_user_search` MCP tool searches Confluence users by display name or email, with a `limit` parameter (`0` = unlimited, default 25)
- **MCP AI Tools** ([#605](https://github.com/rust-works/omni-dev/issues/605)): Adds `ai_chat` (single-turn chat with the configured AI model) and `claude_skills_sync` / `claude_skills_clean` / `claude_skills_status` (worktree-aware skill distribution) as MCP tools. `ai_chat` is single-response (no streaming); skills tools accept a `worktrees` flag and a `format` selector (`"text"` or `"yaml"`). The skill-mutation tools operate relative to the MCP server process's current working directory.
- **MCP Config & Auth Tools** ([#605](https://github.com/rust-works/omni-dev/issues/605)): Adds `config_models_show` (returns the embedded `models.yaml` listing every AI model the CLI knows about) and `atlassian_auth_status` (reports Atlassian credential presence per scope as boolean flags, never leaking secret values). A new `atlassian::auth::status()` helper provides the read-only check.
- **MCP Server Hardening** ([#607](https://github.com/rust-works/omni-dev/issues/607)): Production hardening for the MCP server — input validators at the tool boundary (`range`, `repo_path`, JIRA key, Confluence id) return clear `invalid_params` errors on malformed input; a 100 KB default response cap with a `truncated`/`original_bytes`/`limit_bytes` marker for oversized payloads; cancellation support via the rmcp `CancellationToken` that returns early from blocking git work when a client cancels; per-tool `debug!` logs on invocation and a startup `info!` event listing compiled-in feature flags; an integration test that drives the binary and asserts every stdout frame is a valid JSON-RPC message. CI now runs `cargo build`/`test`/`clippy` with and without `--features mcp`.
- **Claude Skills Status** ([#558](https://github.com/rust-works/omni-dev/issues/558)): New `ai claude skills status` subcommand reports the symlinks and managed exclude-block entries left behind by prior `sync` runs, with `--worktrees` to aggregate across every worktree and `--format {text,yaml}` for machine-readable output
- **Claude Skills YAML Output** ([#558](https://github.com/rust-works/omni-dev/issues/558)): `ai claude skills sync` and `ai claude skills clean` now accept `--format {text,yaml}` (default `text`), producing a structured YAML report when invoked with `--format yaml`

### Changed
- **Claude Skills Exclude File Format** ([#558](https://github.com/rust-works/omni-dev/issues/558)): Entries in `.git/info/exclude` written by `sync` are now wrapped in a managed `# BEGIN omni-dev-skills (managed — do not edit)` / `# END omni-dev-skills` block so that `clean` can reverse the operation precisely. Clean break: bare `.claude/skills/*/` lines written by earlier builds are not recognised by the new `clean` and must be removed manually

## [0.22.0] - 2026-04-19

### Added
- **Confluence Bulk Space Download** ([#556](https://github.com/rust-works/omni-dev/issues/556)): `confluence download` now accepts `--space <KEY>` to recursively download every page in a Confluence space, plus `--title-filter` to download only pages whose title contains a substring (case-insensitive)
- **Confluence Children Command** ([#557](https://github.com/rust-works/omni-dev/issues/557)): New `confluence children` command for traversing page hierarchies, with `--space` and `--recursive` options for whole-space and recursive subtree listing
- **JIRA Comment Pagination** ([#543](https://github.com/rust-works/omni-dev/issues/543)): `jira comment list` now auto-paginates the JIRA comments REST API (previously only the first page was returned) and accepts a `--limit` flag to cap the total number of comments (use `0` for unlimited)
- **Confluence Comment Pagination** ([#544](https://github.com/rust-works/omni-dev/issues/544)): `confluence comment list` now auto-paginates the underlying API, returning every comment rather than just the first page
- **YAML Stream Output** ([#546](https://github.com/rust-works/omni-dev/issues/546)): New `-o yamls` output format emits results as `---`-separated YAML documents (YAML multi-document streams). For sequence results, each item becomes its own document; other values emit as a single `---`-prefixed document. Streams parse with standard YAML tooling (`yaml.safe_load_all()`, `yq`) and enable future per-page streaming for auto-paginated commands.
- **JSONL Output Format** ([#545](https://github.com/rust-works/omni-dev/issues/545)): New `-o jsonl` output format emits results as newline-delimited JSON (one JSON value per line), suitable for streaming consumption by `jq`, `fx`, and other line-oriented JSON tools
- **Claude Skills Sync/Clean** ([#558](https://github.com/rust-works/omni-dev/issues/558)): New `claude skills sync` and `claude skills clean` subcommands for worktree-aware skill distribution, allowing skills to be propagated consistently across multiple git worktrees of the same project

### Changed
- **CI Coverage**: Switched coverage tooling from `cargo-tarpaulin` to `cargo-llvm-cov` ([#589](https://github.com/rust-works/omni-dev/issues/589)) to eliminate `.await?` false negatives and improve accuracy for async code, macros, and generics
- **Atlassian Command Refactor** ([#281](https://github.com/rust-works/omni-dev/issues/281)): Extract `run_*` handler functions from the `execute` methods across Atlassian CLI commands, consolidating parameter structs (`DownloadParams`) and expanding wiremock coverage for every handler

### Fixed
- **Null ADF Input** ([#591](https://github.com/rust-works/omni-dev/issues/591)): `convert from-adf` no longer errors on `null` JSON input (empty Jira descriptions); null is now interpreted as an empty ADF document
- **CommonMark Code Span Handling** ([#578](https://github.com/rust-works/omni-dev/issues/578)): `convert to-adf` no longer splits code-marked text containing backtick characters. Code-span rendering now picks the minimum backtick delimiter length that avoids collisions and applies the CommonMark space-padding rule; the parser matches multi-backtick delimiters with exact-length matching and strips padding spaces symmetrically
- **Integer vs Float Table Width** ([#577](https://github.com/rust-works/omni-dev/issues/577)): ADF→JFM→ADF round-trips no longer coerce integer table width values to floats. A shared `parse_numeric_attr`/`fmt_numeric_attr` helper pair preserves integer-vs-float JSON type based on whether the source had a decimal point
- **Integer/Float in Numeric Attributes** ([#555](https://github.com/rust-works/omni-dev/issues/555)): `layoutColumn`, `mediaSingle`, and file-attachment `media` width/height/`mediaWidth` attributes now preserve the original integer-vs-float JSON number type on round-trip, preventing byte-level JSON inequalities and potential schema validation failures
- **Combined Emoji ShortNames** ([#576](https://github.com/rust-works/omni-dev/issues/576)): Emoji nodes with combined shortNames like `:slightly_smiling_face::bow:` are no longer split into multiple nodes during ADF→JFM→ADF round-trips. The inline parser now extends the match through adjacent `:name:` shortcodes before checking for a trailing attribute directive
- **Pipe Characters in Table Cells** ([#579](https://github.com/rust-works/omni-dev/issues/579)): Literal `|` characters inside pipe-table cell content (including inside inline code spans) are now escaped as `\|` on render and parsed as literal pipes on input, preventing table cells from being split at non-separator pipes
- **Code-Block & Unicode Emoji Shortcodes** ([#552](https://github.com/rust-works/omni-dev/issues/552)): Two ADF↔Markdown round-trip bugs fixed: hardBreak continuation no longer consumes 2-space-indented fenced code blocks or `:::` container directives as continuation lines, and emoji shortcode escaping now uses Unicode `is_alphanumeric` (matching the parser) rather than ASCII-only, so patterns like `:Café:` and `:配置:` are escaped and survive round-trips intact
- **Card URL Brackets** ([#553](https://github.com/rust-works/omni-dev/issues/553)): `::card[...]` / `:card[...]` directives now round-trip correctly even when the URL contains unbalanced `]` or newline characters. URLs that cannot be safely embedded in bracket content are emitted using the quoted `url` attribute form. Additionally, bare URLs inside emphasis, strikethrough, link labels, bracketed spans, or span directives are no longer incorrectly promoted to `inlineCard` nodes (which was silently dropping the enclosing marks)
- **Spurious order=1 on orderedList** ([#547](https://github.com/rust-works/omni-dev/issues/547)): Converting an ADF `orderedList` with no attrs through JFM and back no longer adds a spurious `{"order": 1}` attrs field to the node
- **ADF Mark Ordering** ([#549](https://github.com/rust-works/omni-dev/issues/549)): Inline mark ordering is now preserved across ADF→JFM→ADF round-trips. Markdown wrappers are emitted in mark-array order (outermost first) rather than a fixed priority, so every permutation of `em`, `strong`, `strike`, `underline`, `link`, `annotation`, `textColor`, `backgroundColor`, and `subsup` survives with its original ordering intact
- **Media `occurrenceKey` & Attribute Quoting** ([#550](https://github.com/rust-works/omni-dev/issues/550)): The `occurrenceKey` attribute on `mediaSingle` and `mediaInline` nodes is now preserved on round-trip. Attribute values containing spaces, quotes, closing braces, or backslashes are now quoted and escaped correctly, so arbitrary `id`, `collection`, `url`, `alt`, `localId`, and `occurrenceKey` values round-trip losslessly
- **Annotation-Link Round-Trip Test URL** ([#574](https://github.com/rust-works/omni-dev/pull/574)): Correct the URL used in the annotation-link round-trip test (typo fix)
- **Confluence User Search** ([#542](https://github.com/rust-works/omni-dev/issues/542)): `confluence user search` no longer fails with `missing field 'accountId'` deserialization errors. The response parser now reads the nested `user` object returned by `/wiki/rest/api/search/user` and tolerates user records (such as app users or deactivated users) that omit `accountId`.
- **Empty Task Checkboxes** ([#548](https://github.com/rust-works/omni-dev/issues/548)): Recognise `- [ ]` and `- [x]` markdown task markers even when the checkbox is not followed by a trailing space. Fixes ADF round-trip drift where empty `taskItem` nodes were parsed as `listItem` nodes containing literal `[ ]` text
- **Literal Checkbox Text in Bullet Lists** ([#548](https://github.com/rust-works/omni-dev/issues/548)): Escape the leading `[` when rendering a `bulletList` item whose literal text begins with a sequence that looks like a task checkbox marker (`[ ]`, `[x]`, or `[X]` followed by space, newline, or end), preventing `to-adf` from falsely promoting these bullet items to `taskList`/`taskItem` on round-trip
- **ADF Round-Trip URL Brackets** ([#551](https://github.com/rust-works/omni-dev/issues/551)): Preserve square brackets in URLs embedded in link-marked text so ADF→JFM→ADF round-trips no longer leak `\[`/`\]` escapes or split the text into corrupted `inlineCard` nodes
- **ADF Mark Combinations** ([#554](https://github.com/rust-works/omni-dev/issues/554)): `textColor`, `backgroundColor`, `subsup`, `underline`, and `annotation` marks were silently dropped when combined with a `code` mark or with each other. Marks are now preserved by nesting `:span[…]{…}` and `[…]{…}` wrappers based on the original mark order
- **Underscore boundary in span directives** ([#554](https://github.com/rust-works/omni-dev/issues/554)): `from-adf` now escapes underscores at text-node boundaries (per the CommonMark intraword rule). Previously, a plain text node ending with `_ ` followed by a textColor span whose text started with `_` produced JFM that the parser saw as italic, destroying the span directive and losing the textColor mark
