## Role

Detect documentation drift, validate doc coverage, align docs with code changes, run full documentation health pipeline

## Skills

- detect-doc-drift
- align-documentation
- harness-knowledge-mapper
- validate-context-engineering
- harness-docs-pipeline

## Steps

1. Run `harness check-docs` (always)
2. Run `harness validate` (always)
3. Run `harness scan` (always)

## Methodology

# Detect Doc Drift

> Detect documentation that has drifted from code. Find stale docs before they mislead developers and AI agents.

## When to Use

- After completing a feature, bug fix, or refactoring
- During code review — check if the changed files have associated docs that need updating
- As a periodic hygiene check (weekly or per-sprint)
- When `on_post_feature` or `on_doc_check` triggers fire
- When onboarding reveals confusion caused by outdated documentation
- NOT during active development — wait until the code is stable before checking docs
- NOT for writing new documentation from scratch (use align-documentation instead)

## Process

### Phase 1: Scan — Run Drift Detection

1. **Run `harness check-docs`** to identify all documentation issues. Capture the full output.

2. **Run `harness cleanup --type drift`** for a deeper analysis that cross-references code changes against documentation references.

3. **Check for stale constraints.** Run `detect_stale_constraints` alongside drift detection to find architectural constraints that no longer match the codebase.

4. **Optionally, run `git diff` against a baseline** (last release, last sprint, etc.) to identify which code files changed. This helps prioritize — docs for recently changed files are most likely to be drifted.

### Graph-Enhanced Context (when available)

When a knowledge graph exists at `.harness/graph/`, use graph queries for faster, more accurate drift detection:

- `query_graph` — find `documents` edges where the target code node has changed since the doc node was last updated

When a graph is available, drift is simply stale edges: doc-to-code edges where the code side has been modified more recently than the doc side. This replaces regex pattern matching and catches semantic drift that text search misses. Fall back to file-based commands if no graph is available.

### Pipeline Context (when orchestrated)

When invoked by `harness-docs-pipeline`, check for a `pipeline` field in `.harness/handoff.json`:

- If `pipeline` field exists: read `DocPipelineContext` from it
  - Use `pipeline.exclusions` to skip findings that were already addressed in a previous phase
  - Write `DriftFinding[]` results back to `pipeline.driftFindings` in handoff.json
  - This enables the orchestrator to track findings across phases and avoid double-counting
- If `pipeline` field does not exist: behave exactly as today (standalone mode)

No changes to the skill's interface or output format — the pipeline field is purely additive.

### Phase 2: Identify — Classify Drift Types

Categorize each finding into one of these drift types:

**Renamed but not updated:**
A function, class, variable, or file was renamed in code, but documentation still references the old name. This is the most common type of drift.

- Example: `calculateShipping()` was renamed to `computeShippingCost()`, but AGENTS.md and three inline comments still say `calculateShipping`.

**New code with no docs:**
A new module, function, or API was added but no documentation entry exists. This is not "drift" in the strict sense but a gap that grows into drift over time.

- Example: `src/services/notification-service.ts` was added two sprints ago. It has 5 public exports. No AGENTS.md section, no doc page, no inline doc comments beyond basic JSDoc.

**Deleted code still referenced:**
A file, function, or feature was removed, but documentation still describes it as if it exists. This actively misleads readers.

- Example: `src/utils/legacy-parser.ts` was deleted. The architecture doc still includes it in the data flow diagram. AGENTS.md still warns about its quirks.

**Changed behavior not reflected:**
A function's signature, return type, error handling, or side effects changed, but the documentation describes the old behavior.

- Example: `createUser()` now throws `ValidationError` instead of returning `null` on invalid input. The API docs still say "returns null if validation fails."

**Moved code with stale paths:**
A file or module was moved to a different directory, but documentation references the old path.

- Example: `src/helpers/format.ts` was moved to `src/utils/format.ts`. Three doc files and AGENTS.md reference the old path.

### Phase 3: Prioritize — Rank by Impact

Not all drift is equally harmful. Prioritize fixes:

**Critical (fix immediately):**

- Public API documentation that describes wrong behavior — external consumers will write broken code
- AGENTS.md sections that reference deleted files — AI agents will hallucinate about non-existent code
- README getting-started guides with wrong commands — new developers cannot onboard

**High (fix before next release):**

- Internal API docs with wrong signatures — developers waste time debugging
- Architecture docs with stale diagrams — wrong mental models lead to wrong decisions
- Frequently accessed docs with broken links — high-traffic pages with dead ends

**Medium (fix in next sprint):**

- Internal docs for stable code — low change rate means low confusion rate
- Comments in rarely modified files — few people read them
- Edge case documentation — affects few users

**Low (fix when convenient):**

- Stylistic inconsistencies in docs (capitalization, formatting)
- Redundant documentation that says the same thing in multiple places
- Historical notes that are outdated but clearly marked as historical

### Phase 4: Report — Generate Actionable Output

For each drift finding, provide:

1. **File and line number** of the drifted documentation
2. **The specific stale content** (quote the exact text that is wrong)
3. **What changed in code** (the commit, file, and nature of the change)
4. **Suggested fix** (the replacement text or action needed)
5. **Priority tier** (Critical / High / Medium / Low)

Group findings by documentation file so that fixes can be applied file-by-file.

## Harness Integration

- **`harness check-docs`** — Primary tool. Scans all documentation files for broken references, stale paths, and missing entries.
- **`harness cleanup --type drift`** — Deeper analysis that cross-references git history with documentation references to detect semantic drift.
- **`harness cleanup --type drift --json`** — Machine-readable output for automated pipelines.
- **`harness fix-drift`** — Auto-fix simple drift issues after review (use align-documentation skill for applying fixes).

## Success Criteria

- `harness check-docs` reports zero errors
- All file paths referenced in documentation resolve to existing files
- All function/class names referenced in documentation match current code
- All API documentation matches current function signatures and behavior
- No documentation references deleted files, functions, or features
- Drift findings are prioritized and assigned to the appropriate fix cycle

## Rationalizations to Reject

| Rationalization                                                           | Why It Is Wrong                                                                                                                      |
| ------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| "The docs are close enough -- a renamed function is obvious from context" | Renamed references in AGENTS.md cause AI agents to hallucinate about non-existent code. Precision matters.                           |
| "We only changed internal code, so the docs do not need checking"         | Internal API docs with wrong signatures waste developer debugging time. Changed-behavior-not-reflected drift is High priority.       |
| "There are too many findings to deal with right now, so skip the scan"    | The escalation protocol exists for this case: focus on Critical and High items, create a tracking issue for the rest.                |
| "We can rely on code review to catch stale docs"                          | Code reviewers focus on code correctness, not documentation cross-references. harness check-docs catches what humans routinely miss. |

## Examples

### Example: Renamed function detected

**Drift finding:**

```
DRIFT: Renamed reference detected
  Doc: AGENTS.md:47
  Stale text: "Use `calculateShipping()` to compute shipping costs"
  Code change: calculateShipping renamed to computeShippingCost (commit a1b2c3d)
  File: src/services/shipping.ts:24
  Priority: High
  Suggested fix: Replace `calculateShipping()` with `computeShippingCost()`
```

### Example: Deleted file still documented

**Drift finding:**

```
DRIFT: Reference to deleted file
  Doc: docs/architecture.md:112
  Stale text: "The legacy parser (src/utils/legacy-parser.ts) handles XML input"
  Code change: File deleted in commit d4e5f6g, functionality merged into unified-parser.ts
  Priority: Critical
  Suggested fix: Update section to reference unified-parser.ts, remove legacy parser description
```

### Example: New module with no documentation

**Drift finding:**

```
GAP: Undocumented module
  File: src/services/notification-service.ts
  Created: commit h7i8j9k (3 weeks ago)
  Public exports: NotificationService, NotificationType, sendNotification
  Imported by: 4 modules
  Documentation references: 0
  Priority: High
  Suggested fix: Add AGENTS.md section describing purpose, constraints, and public API
```

## Escalation

- **When drift is extensive (>30 findings):** Do not try to fix everything. Focus on Critical and High priority items. Create a tracking issue for the remaining items and schedule them across sprints.
- **When you cannot determine the correct replacement text:** The code change may have been complex. Check the commit message and PR description for context. If still unclear, flag the finding for the original author to resolve.
- **When documentation is in a format you cannot parse:** Some docs may be in wiki pages, Confluence, or other external systems. Report the finding with a link and flag it for manual review.
- **When drift reveals a deeper problem (code changed but nobody knew):** This suggests a process gap. Recommend adding `harness check-docs` to the CI pipeline or pre-merge hooks to catch drift at the source.

# Align Documentation

> Sync documentation with code after implementation changes. Keep AGENTS.md, API docs, and architecture docs accurate by mapping code changes to their documentation impact.

## When to Use

- After completing a feature implementation (post-merge or post-commit)
- After fixing a bug that changes observable behavior
- After a refactoring that renames, moves, or restructures code
- When detect-doc-drift reports findings that need fixing
- When `on_post_feature` or `on_post_merge` triggers fire
- NOT during active development — wait until the code is stable
- NOT for creating documentation for a brand-new project (use validate-context-engineering for initial setup)
- NOT for fixing code — this skill only changes documentation

## Process

### Phase 1: Detect — Identify What Changed

1. **Run `git diff` against the appropriate baseline.** Choose the baseline based on context:
   - After a feature: diff against the branch point (`git diff main...HEAD`)
   - After a bug fix: diff against the commit before the fix
   - After a refactoring: diff against the commit before refactoring started
   - Periodic sync: diff against the last documentation sync commit

2. **Extract the list of changed files.** For each changed file, note:
   - File path (current and previous if renamed/moved)
   - Nature of change (added, modified, deleted, renamed)
   - Changed exports (new, removed, renamed, signature changed)
   - Changed behavior (different return values, new error types, new side effects)

3. **Run `harness check-docs`** to identify any documentation that already has broken references due to the changes.

### Graph-Enhanced Context (when available)

When a knowledge graph exists at `.harness/graph/`, use graph queries for faster, more accurate context:

- `query_graph` — find `documents` edges pointing to nodes changed in this diff
- `get_impact` — auto-suggest which docs need updating after code changes

Replaces manual doc-to-code correlation. Fall back to file-based commands if no graph is available.

### Pipeline Context (when orchestrated)

When invoked by `harness-docs-pipeline`, check for a `pipeline` field in `.harness/handoff.json`:

- If `pipeline` field exists: read `DocPipelineContext` from it
  - Read `pipeline.driftFindings` to know which fixes to apply (pre-classified by safety)
  - If `pipeline.fixBatch` is set, apply only those specific fixes rather than running full detection
  - Write applied fixes as `DocFix[]` back to `pipeline.fixesApplied`
  - This enables the convergence loop to track fix verification status
- If `pipeline` field does not exist: behave exactly as today (standalone mode)

No changes to the skill's interface or output format — the pipeline field is purely additive.

### Phase 2: Map — Connect Code Changes to Documentation

For each changed file, identify all documentation that references it:

**AGENTS.md sections:**

- Knowledge map entries that reference the file path
- Architecture descriptions that mention the module
- Constraint documentation that references the file's layer or patterns
- Onboarding guides that walk through the file

**API documentation:**

- JSDoc/TSDoc comments in the changed files themselves
- Generated API doc pages that pull from the changed files
- README examples that demonstrate the changed functions
- Tutorial or guide pages that use the changed code

**Architecture documentation:**

- Diagrams that include the changed module
- Data flow descriptions that reference the changed functions
- Layer descriptions that list the changed file
- Dependency documentation that references the changed imports

**Inline code comments:**

- Comments in OTHER files that reference the changed file or function
- TODO comments that reference the changed behavior
- Workaround comments that may no longer apply after the change

### Phase 3: Generate — Draft Documentation Updates

For each affected documentation location:

1. **Draft the specific text change.** Show the old text and the new text. Keep the existing style and tone — documentation updates should be invisible in terms of voice.

2. **Preserve context.** When updating a section, do not just change the specific reference — read the surrounding paragraph and ensure it still makes sense. A renamed function may require updating the explanatory text around it, not just the function name.

3. **Handle deletions carefully.** When code is deleted, do not just delete the documentation reference. Consider whether the section should be removed entirely, replaced with information about the replacement, or noted as deprecated.

4. **Add new sections when needed.** If a new module was added, draft a complete documentation section following the existing AGENTS.md structure and style.

### Phase 4: Validate — Verify Documentation Accuracy

1. **Run `harness check-docs`** to verify all links and references resolve correctly after the updates.

2. **Cross-check each update against the actual code.** Read the updated documentation and verify every claim by looking at the code. Documentation that is wrong is worse than documentation that is missing.

3. **Verify no orphaned references remain.** Search documentation files for any remaining references to old names, old paths, or deleted features.

4. **Run `harness fix-drift`** to catch any remaining simple drift issues that manual review missed.

### Graph Refresh

If a knowledge graph exists at `.harness/graph/`, refresh it after code changes to keep graph queries accurate:

```
harness scan [path]
```

Skipping this step means subsequent graph queries (impact analysis, dependency health, test advisor) may return stale results.

5. **Commit the documentation update.** Use a commit message that references the original change: "docs: update AGENTS.md for notification service refactoring" or "docs: sync API docs after auth module rename."

## What to Update

### AGENTS.md Knowledge Map

- File paths and module names (renamed or moved files)
- Module purpose descriptions (changed responsibilities)
- Constraint descriptions (new or changed rules)
- Relationship descriptions (new or changed dependencies)
- Gotcha sections (resolved gotchas, new gotchas)

### Inline Code Comments

- Function/class doc comments in the changed files (JSDoc, TSDoc)
- Comments in other files that reference the changed code
- TODO comments that reference completed or changed work
- Workaround comments for issues that may now be resolved

### Documentation Pages (docs/)

- API reference pages that describe changed functions
- Architecture pages that diagram changed modules
- Tutorial and guide pages that demonstrate changed code
- Getting-started guides if entry points changed
- Changelog entries for user-facing changes

## Harness Integration

- **`harness check-docs`** — Run before and after updates. Identifies broken references and validates that all documentation links resolve.
- **`harness fix-drift`** — Auto-fix simple drift issues (broken file paths, renamed references) after manual review confirms correctness.
- **`harness fix-drift --json`** — Machine-readable output for tracking what was auto-fixed.
- **`harness validate`** — Run after documentation changes to verify overall project health is maintained.

## Success Criteria

- `harness check-docs` passes with zero errors after documentation updates
- Every code change from the diff has been mapped to its documentation impact
- All file paths in documentation match current file locations
- All function/class names in documentation match current code
- All behavioral descriptions in documentation match current implementation
- Documentation updates are committed with clear references to the triggering code change
- No orphaned references to old names, paths, or deleted features remain

## Rationalizations to Reject

| Rationalization                                                               | Why It Is Wrong                                                                                                                                        |
| ----------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| "The code change is small, so docs probably do not need updating"             | A single function signature change changes the contract for every consumer. Map every code change to its documentation impact regardless of diff size. |
| "I updated the main reference -- the other mentions can wait"                 | Orphaned references in AGENTS.md and tutorials actively mislead agents and developers. Phase 4 requires verifying no orphaned references remain.       |
| "I will match the new documentation to what I think the code does"            | Phase 4 requires cross-checking each update against the actual code. Documentation that is wrong is worse than documentation that is missing.          |
| "The existing doc style is inconsistent, so I will improve it while aligning" | Follow the existing style. Documentation alignment is about accuracy, not style improvement. Style changes should be a separate effort.                |

## Examples

### Example: Syncing docs after a module rename

**Code change:** `src/services/mailer.ts` renamed to `src/services/email-service.ts`. Functions `sendMail()` and `formatMailBody()` renamed to `sendEmail()` and `formatEmailBody()`.

**Documentation impact map:**

```
AGENTS.md:34      — "mailer.ts handles email delivery" → update path and description
AGENTS.md:78      — "Use sendMail() for all outbound email" → update function name
docs/api.md:156   — sendMail() API reference → update name and import path
docs/arch.md:45   — architecture diagram lists "mailer" → update to "email-service"
src/controllers/user-controller.ts:12 — comment "// delegates to mailer" → update
```

**Updates applied:**

- AGENTS.md: updated two sections with new file path and function names
- docs/api.md: updated function reference and import example
- docs/arch.md: updated module name in architecture description
- src/controllers/user-controller.ts: updated inline comment

**Validation:** `harness check-docs` passes. All references resolve. Commit: "docs: sync documentation after mailer rename to email-service"

### Example: Syncing docs after adding error handling

**Code change:** `createUser()` in `src/services/user-service.ts` now throws `ValidationError` instead of returning `null` on invalid input.

**Documentation impact map:**

```
docs/api.md:89    — "Returns null if validation fails" → update to describe thrown error
AGENTS.md:52      — No mention of error handling → add note about ValidationError
src/services/user-service.ts:15 — JSDoc @returns tag → update, add @throws tag
```

**Updates applied:**

- docs/api.md: replaced "returns null" with "throws ValidationError" and added example
- AGENTS.md: added note about error handling pattern in user-service section
- JSDoc: updated @returns, added @throws ValidationError

**Validation:** `harness check-docs` passes. Commit: "docs: update documentation for createUser error handling change"

## Escalation

- **When you cannot determine what documentation is affected:** Run `harness check-docs` for automated detection. For manual analysis, search all `.md` files and code comments for the old name/path. If the change is large, use detect-doc-drift first to get a complete inventory.
- **When documentation is in an external system (wiki, Confluence):** Document the needed change and flag it for manual update. Include the specific text that needs changing and the correct replacement.
- **When the code change is so large that documentation needs a rewrite:** Break the documentation update into sections. Update one section at a time, validating after each. Do not attempt a full rewrite in one pass.
- **When you disagree with the existing documentation style:** Follow the existing style. Documentation alignment is about accuracy, not style improvement. Style changes should be a separate, deliberate effort.

# Harness Knowledge Mapper

> Auto-generate always-current knowledge maps from graph topology. Never stale because it's computed, not authored.

## When to Use

- When AGENTS.md is outdated or doesn't exist — generate it from the graph
- After major refactoring — regenerate the knowledge map to reflect new structure
- On scheduled basis — keep documentation aligned with code
- When `on_commit` to main triggers fire
- NOT for validating existing AGENTS.md (use validate-context-engineering)
- NOT for fixing documentation drift (use align-documentation)

## Prerequisites

A knowledge graph at `.harness/graph/` enables full analysis. If no graph exists,
the skill uses static analysis fallbacks (see Graph Availability section).
Run `harness scan` to enable graph-enhanced analysis.

### Graph Availability

Before starting, check if `.harness/graph/graph.json` exists.

**If graph exists:** Check staleness — compare `.harness/graph/metadata.json`
scanTimestamp against `git log -1 --format=%ct` (latest commit timestamp).
If graph is more than 10 commits behind (`git log --oneline <scanTimestamp>..HEAD | wc -l`),
run `harness scan` to refresh before proceeding. (Staleness sensitivity: **Medium**)

**If graph exists and is fresh (or refreshed):** Use graph tools as primary strategy.

**If no graph exists:** Output "Running without graph (run `harness scan` to
enable full analysis)" and use fallback strategies for all subsequent steps.

### Pipeline Context (when orchestrated)

When invoked by `harness-docs-pipeline`, check for a `pipeline` field in `.harness/handoff.json`:

- If `pipeline` field exists: read `DocPipelineContext` from it
  - If `pipeline.bootstrapped === true`, this is a bootstrap invocation — generate full AGENTS.md without confirmation prompt
  - Write any generated documentation back as `DocFix[]` to `pipeline.fillsApplied`
  - This enables the orchestrator to track what was generated and verify it
- If `pipeline` field does not exist: behave exactly as today (standalone mode)

No changes to the skill's interface or output format — the pipeline field is purely additive.

## Process

### Phase 1: SURVEY — Query Graph for Structure

1. **Module hierarchy**: Query for module nodes and their `contains` edges to file nodes.

   ```
   query_graph(rootNodeIds=[all module nodes], includeTypes=["module", "file"], includeEdges=["contains"])
   ```

2. **Entry points**: Find file nodes with high out-degree but low in-degree (they initiate dependency chains).

   ```
   search_similar(query="main entry point index")
   ```

3. **Layer structure**: Query for layer nodes if defined.

4. **Dependency flow**: For each module, trace outbound `imports` edges to other modules.

   ```
   get_relationships(nodeId=<module>, direction="outbound", depth=1)
   ```

#### Fallback (without graph)

When no graph is available, use directory structure and file analysis:

1. **Module hierarchy from directories**: Use the directory structure as the module hierarchy — each directory represents a module. Glob for all source files to build the tree.
2. **Entry points**: Check `package.json` for `main` and `exports` fields. Glob for `src/index.*` and `index.*` patterns. These are the entry points.
3. **Source file inventory**: Glob for all source files (`**/*.ts`, `**/*.tsx`, `**/*.js`, `**/*.jsx`, etc.).
4. **Documentation inventory**: Glob for all doc files (`**/*.md`, `docs/**/*`).
5. **Undocumented module detection**: Diff the source directory set against the doc directory set. Source directories with no corresponding docs (no README.md, no matching doc file) are undocumented.
6. **Existing knowledge map**: Read existing AGENTS.md if present for current knowledge map state.
7. **Dependency flow (approximate)**: Parse import statements in each module's files to determine which modules depend on which others.

> Fallback completeness: ~50% — no semantic grouping; modules grouped by directory only; no cross-cutting concern detection.

### Phase 2: GENERATE — Build Knowledge Map

Generate markdown sections following AGENTS.md conventions:

1. **Repository Structure**: Module hierarchy with brief descriptions derived from file contents and function names.

2. **Key Entry Points**: Files identified as entry points with their purpose (inferred from exports and naming).

3. **Module Dependencies**: For each module, list what it depends on and what depends on it. Format as a dependency table.

4. **API Surface**: Public exports from each module, grouped by type (functions, classes, types).

5. **Patterns and Conventions**: Detected patterns from graph structure (e.g., "all services follow Repository pattern", "tests co-located with source").

### Phase 3: AUDIT — Identify Coverage Gaps

1. **Undocumented modules**: Use `check_docs` to find code nodes without `documents` edges.

2. **Missing descriptions**: Modules with no README or doc file.

3. **Stale references**: If an existing AGENTS.md exists, compare its file references against the graph to find mentions of files that no longer exist.

### Phase 4: OUTPUT — Write Knowledge Map

1. **Default**: Write to AGENTS.md in project root.
2. **Custom path**: Write to specified output path.
3. **Diff mode**: If AGENTS.md exists, show what changed rather than overwriting.

### Output

```
## Generated Knowledge Map

### Repository Structure
- **packages/core/** — Core library: context assembly, entropy detection, constraints, feedback
  - src/context/ — Token budget, filtering, doc coverage, knowledge map validation
  - src/entropy/ — Drift detection, dead code analysis, pattern violations
  - src/constraints/ — Layer validation, circular dependency detection, boundaries
  - src/feedback/ — Self-review, peer review, diff analysis

- **packages/graph/** — Knowledge graph: store, query, ingest, search
  - src/store/ — LokiJS-backed graph store, vector store, serialization
  - src/query/ — ContextQL traversal, projection
  - src/ingest/ — Code, git, knowledge, connector ingestion
  - src/search/ — FusionLayer hybrid search

### Entry Points
1. packages/core/src/index.ts — Core library barrel export
2. packages/graph/src/index.ts — Graph library barrel export
3. packages/cli/src/index.ts — CLI entry point (Commander.js)
4. packages/mcp-server/src/server.ts — MCP server registration

### Coverage Gaps
- 3 modules have no documentation
- 5 files have no test coverage
```

### Graph Refresh

After generating documentation, refresh the graph so new `documents` edges reflect the updated docs:

```
harness scan [path]
```

This ensures subsequent graph queries (impact analysis, drift detection) include the newly generated documentation.

## Harness Integration

- **`harness scan`** — Recommended before this skill for full graph-enhanced analysis. If graph is missing, skill uses directory structure fallbacks.
- **`harness validate`** — Run after acting on findings to verify project health.
- **Graph tools** — This skill uses `query_graph`, `get_relationships`, and `check_docs` MCP tools.

## Success Criteria

- Knowledge map generated with all sections (structure, entry points, dependencies, API surface, patterns)
- Coverage gaps identified (undocumented modules, missing descriptions, stale references)
- Output written to AGENTS.md (or specified path) in proper markdown format
- Report follows the structured output format
- All findings are backed by graph query evidence (with graph) or directory/file analysis (without graph)

## Rationalizations to Reject

| "The graph is a few commits behind, but it is close enough for knowledge mapping"       | If the graph is more than 10 commits behind, run harness scan before proceeding. A stale graph produces a knowledge map with missing modules.                     |
| "No graph exists, so this skill cannot produce useful output"                           | The fallback strategy is explicit: use directory structure and file analysis. Fallback completeness is ~50%, significantly better than nothing.                   |
| "The existing AGENTS.md is outdated, so I will overwrite it with the generated version" | Never overwrite without confirmation. Existing AGENTS.md may contain carefully authored context the graph cannot infer.                                           |
| "The module descriptions I inferred from function names are accurate enough"            | Inferred descriptions are starting points. Phase 3 (AUDIT) exists to identify coverage gaps. Name-based inference misses purpose, constraints, and relationships. |

## Examples

### Example: Generating AGENTS.md from Graph

```
Input: No AGENTS.md exists, graph is current after harness scan

1. SURVEY   — query_graph for module hierarchy: 4 packages found
              search_similar for entry points: 4 identified
              get_relationships for dependency flow per module
2. GENERATE — Built 5 sections: structure, entry points,
              dependencies, API surface, patterns
3. AUDIT    — check_docs found 3 undocumented modules,
              5 files with no test coverage
4. OUTPUT   — Wrote AGENTS.md to project root (new file)

Output:
  AGENTS.md generated (142 lines)
  Coverage gaps: 3 undocumented modules, 5 untested files
  No stale references (fresh generation)
```

## Gates

- **Graph preferred, fallback available.** If no graph exists, use directory structure and file analysis to build the knowledge map. Do not stop — produce the best map possible.
- **Never overwrite without confirmation.** If AGENTS.md exists, show the diff and ask before replacing.

## Escalation

- **When >50% of modules are undocumented**: Flag as critical documentation debt.
- **When graph structure doesn't match directory structure**: The graph may be stale — recommend re-scanning.

# Validate Context Engineering

> Validate AGENTS.md quality and evolve it as the codebase changes. Good context engineering means AI agents always have accurate, current knowledge about the project.

## When to Use

- After adding new files, modules, or packages to the project
- After renaming, moving, or deleting significant files
- After changing public APIs, architectural patterns, or conventions
- When onboarding a new contributor (human or AI) and want to verify context is current
- When `on_context_check` or `on_pre_commit` triggers fire
- Periodically (weekly or per-sprint) as a hygiene check
- NOT when making trivial changes (typo fixes, comment updates, formatting)
- NOT during active feature development — run this between features or at cycle boundaries

## Process

### Phase 1: Audit — Run Automated Checks

1. **Run `harness validate`** to check overall project health. Review any context-related warnings or errors in the output.

2. **Run `harness check-docs`** to detect documentation gaps, broken links, and stale references. Capture the full output for analysis.

3. **Review AGENTS.md manually.** Automated tools catch structural issues but miss semantic drift. Read each section and ask: "Is this still true?"

### Graph-Enhanced Context (when available)

When a knowledge graph exists at `.harness/graph/`, use graph queries for faster, more accurate auditing:

- `query_graph` — find all undocumented code nodes (file nodes without `documents` edges), replacing manual cross-referencing
- `search_similar` — detect stale references in AGENTS.md by matching section text against current code entities

When a graph is available, it IS the source of truth for documentation coverage. Drift = stale or missing edges between code and doc nodes. Fall back to file-based commands if no graph is available.

### Pipeline Context (when orchestrated)

When invoked by `harness-docs-pipeline`, check for a `pipeline` field in `.harness/handoff.json`:

- If `pipeline` field exists: read `DocPipelineContext` from it
  - Use `pipeline.exclusions` to skip findings that were already addressed in the FIX phase
  - Write `GapFinding[]` results back to `pipeline.gapFindings` in handoff.json
  - This enables dedup across FIX and AUDIT phases
- If `pipeline` field does not exist: behave exactly as today (standalone mode)

No changes to the skill's interface or output format — the pipeline field is purely additive.

### Phase 2: Detect Gaps

Categorize findings into four types:

1. **Undocumented files.** New source files, modules, or packages that are not mentioned in AGENTS.md or any knowledge map section. These are the highest priority — an AI agent encountering these files has no context.

2. **Broken links.** References to files, functions, or URLs that no longer exist. These actively mislead agents.

3. **Stale sections.** Content that was accurate when written but no longer reflects reality. Examples: renamed functions still referenced by old name, removed features still described, changed conventions not updated.

4. **Missing context.** Sections that exist but lack critical information. A module is listed but its purpose, constraints, or relationships are not explained. An AI agent can find the file but does not understand why it exists or how to use it correctly.

### Phase 3: Suggest Updates

For each gap, generate a specific suggestion:

- **Undocumented files:** Draft a new section or entry with the file path, purpose, key exports, and relationship to existing modules. Use the existing AGENTS.md style and structure.
- **Broken links:** Identify the correct target (renamed file, moved function) or recommend removal if the target was deleted.
- **Stale sections:** Draft replacement text that reflects current reality. Show the diff between old and new.
- **Missing context:** Draft additional content that fills the gap. Focus on what an AI agent needs to know: purpose, constraints, relationships, and gotchas.

### Phase 4: Apply with Approval

1. **Present all suggestions as a grouped list.** Organize by section of AGENTS.md for easy review.

2. **Apply approved changes.** Update AGENTS.md with the approved suggestions. Preserve existing formatting and style.

3. **Re-run `harness check-docs`** to verify all fixes are clean. No new issues should be introduced.

4. **Commit the update.** Use a descriptive commit message that summarizes what was updated and why.

## What Makes Good AGENTS.md Content

Good context engineering treats AGENTS.md as a **dynamic knowledge base**, not a static document.

- **Accuracy over completeness.** A small, accurate AGENTS.md is better than a comprehensive but stale one. Every statement must be verifiable against the current codebase.
- **Purpose-first descriptions.** Do not just list files. Explain WHY each module exists, what problem it solves, and what constraints apply to it.
- **Relationship mapping.** Show how modules connect. Which modules depend on which? What are the boundaries? An agent reading one section should understand how it fits into the whole.
- **Gotchas and constraints.** Document the non-obvious. What will break if someone does X? What patterns must be followed? What is forbidden and why?
- **Change-friendly structure.** Organize so that adding a new module means adding one section, not updating ten places. Use consistent formatting so automated tools can parse it.
- **Actionable guidance.** Every section should help an agent make correct decisions. "This module handles authentication" is less useful than "This module handles authentication. All auth changes must go through the AuthService class. Direct database access for auth data is forbidden — use the repository layer."

## Harness Integration

- **`harness validate`** — Full project health check. Reports context gaps as part of overall validation.
- **`harness check-docs`** — Focused documentation audit. Detects broken links, missing references, stale sections, and undocumented files.
- **`harness fix-drift`** — Auto-fix simple drift issues (broken links, renamed references). Use after manual review confirms the fixes are correct.

## Success Criteria

- `harness check-docs` passes with zero errors and zero warnings
- Every source file that contains public API or architectural significance is referenced in AGENTS.md
- All file paths and function names in AGENTS.md match the current codebase
- All links (internal and external) resolve correctly
- AGENTS.md sections accurately describe current module purposes, constraints, and relationships
- A new AI agent reading AGENTS.md can navigate the codebase and make correct decisions without additional guidance

## Rationalizations to Reject

| Rationalization                                                            | Why It Is Wrong                                                                                                                                                           |
| -------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| "The automated checks passed, so AGENTS.md is accurate"                    | Phase 1 says automated tools catch structural issues but miss semantic drift. Manual review of each section is required.                                                  |
| "This module is small and internal -- it does not need an AGENTS.md entry" | Undocumented files are the highest priority finding. Even small internal modules need at least a purpose statement.                                                       |
| "AGENTS.md is severely outdated -- let me rewrite it from scratch"         | Do not attempt to fix everything at once when there are >20 issues. Prioritize: broken links first, then undocumented public APIs.                                        |
| "I will add the file paths and leave the descriptions for later"           | Purpose-first descriptions, relationship mapping, and gotchas are what make context engineering useful. A file listing without context is marginally better than nothing. |

## Examples

### Example: New module added but not documented

**Audit output from `harness check-docs`:**

```
WARNING: Undocumented file detected: src/services/notification-service.ts
  - File contains 3 public exports: NotificationService, NotificationType, sendNotification
  - File is imported by 4 other modules
  - No AGENTS.md section references this file
```

**Suggested update:**

```markdown
### Notification Service (`src/services/notification-service.ts`)

Handles all outbound notifications (email, Slack, webhook). All notification delivery
must go through `NotificationService` — direct use of transport libraries (nodemailer,
Slack SDK) outside this module is forbidden.

- `NotificationType` — enum of supported notification channels
- `sendNotification()` — primary entry point; routes to the correct transport
- Requires `NOTIFICATION_CONFIG` environment variables to be set
- Respects rate limits defined in `harness.config.json` under `notifications`
```

**Apply:** Add the section under the Services heading in AGENTS.md. Re-run `harness check-docs` to confirm the warning is resolved.

### Example: Renamed function still referenced by old name

**Audit output:**

```
ERROR: Broken reference in AGENTS.md line 47: `calculateShipping()`
  - Function was renamed to `computeShippingCost()` in commit abc123
  - Located in src/services/shipping.ts
```

**Fix:** Replace `calculateShipping()` with `computeShippingCost()` in AGENTS.md. Verify no other references to the old name exist.

## Escalation

- **When AGENTS.md is severely outdated (>20 issues):** Do not attempt to fix everything at once. Prioritize: broken links first, then undocumented public APIs, then stale descriptions. Batch the work across multiple commits.
- **When you are unsure whether a section is stale:** Check git blame for the section and compare against recent changes to the referenced files. If the section has not been updated since the referenced files changed, it is likely stale.
- **When the project has no AGENTS.md:** Escalate to the human. Creating an AGENTS.md from scratch is a significant decision about project structure and should be done intentionally, not automatically.

# Harness Docs Pipeline

> Orchestrator composing 4 documentation skills into a sequential pipeline with convergence-based remediation, producing a qualitative documentation health report.

## When to Use

- When you want a single-command documentation health check across drift, coverage, links, and freshness
- After major refactoring that may have caused widespread documentation drift
- As a periodic hygiene check (weekly or per-sprint)
- When onboarding a new project that has no AGENTS.md (bootstrap mode)
- When `on_doc_check` triggers fire
- NOT for fixing a single known drift issue (use align-documentation directly)
- NOT for generating AGENTS.md from scratch when you know you have a graph (use harness-knowledge-mapper directly)
- NOT for validating a single file's context (use validate-context-engineering directly)

## Relationship to Sub-Skills

| Skill                        | Pipeline Phase | Role                                        |
| ---------------------------- | -------------- | ------------------------------------------- |
| detect-doc-drift             | DETECT         | Find drift between code and docs            |
| align-documentation          | FIX            | Apply fixes for drift findings              |
| validate-context-engineering | AUDIT          | Find gaps in documentation coverage         |
| harness-knowledge-mapper     | FILL           | Generate/regenerate AGENTS.md and fill gaps |

This orchestrator delegates to sub-skills — it never reimplements their logic. Each sub-skill retains full standalone functionality.

## Iron Law

**The pipeline delegates, never reimplements.** If you find yourself writing drift detection logic, fix application logic, or gap analysis logic inside the pipeline, STOP. Delegate to the dedicated sub-skill.

**Safe fixes are silent, unsafe fixes surface.** Never apply a fix classified as `unsafe` without explicit user approval. Never prompt the user for a fix classified as `safe`.

## Flags

| Flag           | Effect                                                            |
| -------------- | ----------------------------------------------------------------- |
| `--fix`        | Enable convergence-based auto-fix (default: detect + report only) |
| `--no-freshen` | Skip graph staleness check                                        |
| `--bootstrap`  | Force AGENTS.md regeneration even if one exists                   |
| `--ci`         | Non-interactive: apply safe fixes only, report everything else    |

## Shared Context Object

All phases read from and write to a shared `DocPipelineContext`:

```typescript
interface DocPipelineContext {
  // Pipeline state
  graphAvailable: boolean;
  agentsMdExists: boolean;
  bootstrapped: boolean; // true if AGENTS.md was created this run

  // Phase outputs
  driftFindings: DriftFinding[];
  fixesApplied: DocFix[];
  gapFindings: GapFinding[];
  fillsApplied: DocFix[];
  exclusions: Set<string>; // finding IDs already addressed

  // Health verdict
  verdict: 'pass' | 'warn' | 'fail';
  summary: string;
}

interface DriftFinding {
  id: string;
  file: string;
  line?: number;
  driftType: 'renamed' | 'new-code' | 'deleted-code' | 'changed-behavior' | 'moved-code';
  priority: 'critical' | 'high' | 'medium' | 'low';
  staleText: string;
  codeChange: string;
  suggestedFix: string;
  fixSafety: 'safe' | 'probably-safe' | 'unsafe';
}

interface GapFinding {
  id: string;
  file?: string;
  gapType: 'undocumented' | 'broken-link' | 'stale-section' | 'missing-context';
  priority: 'critical' | 'high' | 'medium' | 'low';
  description: string;
  suggestedFix: string;
  fixSafety: 'safe' | 'probably-safe' | 'unsafe';
}

interface DocFix {
  findingId: string;
  file: string;
  oldText: string;
  newText: string;
  safety: 'safe' | 'probably-safe';
  verified: boolean; // harness check-docs passed after applying
}
```

The context is passed to sub-skills via `handoff.json` with a `pipeline` field. Sub-skills check for this field; if absent, they run in standalone mode.

## Process

### Phase 1: FRESHEN — Graph Freshness and AGENTS.md Bootstrap

**Skip this phase if `--no-freshen` flag is set.**

1. **Check graph existence.** Look for `.harness/graph/` directory.
   - If exists: set `context.graphAvailable = true`
   - If not: set `context.graphAvailable = false`, log notice: "No knowledge graph available. Pipeline will use static analysis fallbacks. Run `harness scan` for richer results."

2. **Check graph staleness** (only if graph exists).
   - Count commits since last graph update: `git rev-list --count HEAD ^$(cat .harness/graph/.last-scan-commit 2>/dev/null || echo HEAD)`
   - If >10 commits behind: run `harness scan` to refresh
   - If <=10 commits: proceed with current graph

3. **Check AGENTS.md existence.**
   - If exists and `--bootstrap` not set: set `context.agentsMdExists = true`, proceed to DETECT
   - If exists and `--bootstrap` set: proceed to step 4 (regenerate)
   - If not exists: proceed to step 4

4. **Bootstrap AGENTS.md.**

   **If graph available:**
   - Invoke `harness-knowledge-mapper` to generate AGENTS.md
   - Set `context.bootstrapped = true`
   - Set `context.agentsMdExists = true`

   **If no graph (directory structure fallback):**
   - Glob source directories: `src/*/`, `packages/*/`, `lib/*/`
   - Read `package.json` for project name and description
   - Identify entry points: files matching `src/index.*`, `main` field in package.json
   - List top-level modules: each immediate subdirectory of `src/` (or `packages/`) with its directory name as the module name
   - Generate minimal AGENTS.md:

     ```markdown
     # AGENTS.md

     > Generated from directory structure. Run `harness scan` for richer output.

     ## Project

     <name from package.json> — <description from package.json>

     ## Entry Points

     - <each identified entry point>

     ## Modules

     - **<dir-name>/** — <inferred from directory name>
     ```

   - Set `context.bootstrapped = true`
   - Set `context.agentsMdExists = true`

5. Proceed to DETECT phase.

### Phase 2: DETECT — Find Documentation Drift

1. **Write pipeline context to handoff.json.** Set the `pipeline` field in `.harness/handoff.json` with the current `DocPipelineContext` so detect-doc-drift can read it.

2. **Invoke detect-doc-drift.** Run the skill's full process:
   - Phase 1 (Scan): `harness check-docs` and `harness cleanup --type drift`
   - Phase 2 (Identify): Classify each finding into drift types
   - Phase 3 (Prioritize): Rank by impact (Critical > High > Medium > Low)
   - Phase 4 (Report): Structured output

3. **Populate context with DriftFinding objects.** For each finding from detect-doc-drift, create a `DriftFinding` with:
   - `id`: deterministic hash of `file + line + driftType` (for dedup tracking)
   - `driftType`: map to one of `renamed`, `new-code`, `deleted-code`, `changed-behavior`, `moved-code`
   - `priority`: map to `critical`, `high`, `medium`, `low`
   - `fixSafety`: classify using the safety table below

4. **Store findings.** Set `context.driftFindings = <all DriftFinding objects>`.

5. **If `--fix` flag is not set:** Skip to AUDIT phase (Phase 4).

### Fix Safety Classification

| Category        | Safe (apply silently)                                              | Probably safe (present diff)                                                    | Unsafe (surface to user)                                          |
| --------------- | ------------------------------------------------------------------ | ------------------------------------------------------------------------------- | ----------------------------------------------------------------- |
| **Drift fixes** | Update file path where rename is unambiguous; fix import reference | Rewrite description for simple rename/parameter change; update code examples    | Rewrite behavioral explanations; remove sections for deleted code |
| **Gap fills**   | Add entry for new file with obvious single-purpose name            | Add entry for new file requiring description; update AGENTS.md section ordering | Write documentation for complex modules; create new doc pages     |
| **Link fixes**  | Redirect broken link where target is unambiguous                   | Redirect when multiple candidates exist (present options)                       | Remove link when target no longer exists                          |

### Phase 3: FIX — Convergence-Based Drift Remediation

**This phase runs only when `--fix` flag is set.**

#### Convergence Loop

```
previousCount = context.driftFindings.length
maxIterations = 5

while iteration < maxIterations:
  1. Partition findings by safety
  2. Apply safe fixes → verify → record
  3. Present probably-safe fixes → apply approved → verify → record
  4. Surface unsafe fixes to user (no auto-apply)
  5. Re-run detect-doc-drift
  6. newCount = remaining findings
  7. if newCount >= previousCount: STOP (converged)
  8. previousCount = newCount
  9. iteration++
```

#### Step-by-step

1. **Partition findings by fixSafety.**
   - `safeFixes`: findings where `fixSafety === 'safe'`
   - `probablySafeFixes`: findings where `fixSafety === 'probably-safe'`
   - `unsafeFixes`: findings where `fixSafety === 'unsafe'`

2. **Apply safe fixes silently.**
   - Write pipeline context to handoff.json with `pipeline.fixBatch = safeFixes`
   - Invoke align-documentation to apply the fixes
   - Run `harness check-docs` after the batch
   - If check passes: record each fix as a `DocFix` with `verified: true` in `context.fixesApplied`
   - If check fails: revert the batch (`git checkout -- <files>`), record fixes as `verified: false`
   - Add fixed finding IDs to `context.exclusions`

3. **Present probably-safe fixes** (skip in `--ci` mode).
   - For each fix, show the diff (oldText vs newText) to the user
   - Apply user-approved fixes
   - Run `harness check-docs` after the batch
   - Same verify/revert logic as safe fixes
   - Add fixed finding IDs to `context.exclusions`

4. **Surface unsafe fixes.**
   - List each unsafe finding with its `suggestedFix` text
   - Do not apply — user must handle manually
   - In `--ci` mode: log to report, do not prompt

5. **Re-run detect-doc-drift** to check for cascading issues revealed by fixes.
   - If new finding count < previous count: loop back to step 1
   - If new finding count >= previous count: stop (converged or no progress)
   - If max iterations reached: stop

6. **Record remaining unfixed findings** for the REPORT phase.

### Phase 4: AUDIT — Find Documentation Gaps

1. **Write pipeline context to handoff.json.** Update the `pipeline` field with the current `DocPipelineContext` (including `exclusions` from FIX phase).

2. **Invoke validate-context-engineering.** Run the skill's full process:
   - Phase 1 (Audit): `harness validate` and `harness check-docs`
   - Phase 2 (Detect Gaps): Classify into undocumented, broken-link, stale-section, missing-context
   - Phase 3 (Suggest Updates): Generate specific suggestions
   - Phase 4 (Apply): Deferred to FILL phase

3. **Populate context with GapFinding objects.** For each finding, create a `GapFinding` with:
   - `id`: deterministic hash of `file + gapType + description`
   - `gapType`: map to `undocumented`, `broken-link`, `stale-section`, `missing-context`
   - `priority`: map to `critical`, `high`, `medium`, `low`
   - `fixSafety`: classify using the safety table from DETECT phase

4. **Dedup against FIX phase.** Remove any `GapFinding` whose `id` appears in `context.exclusions`. This prevents double-counting items already fixed in the FIX phase.

5. **Store findings.** Set `context.gapFindings = <deduplicated GapFinding objects>`.

6. **If `--fix` flag is not set:** Skip to REPORT phase (Phase 6).

### Phase 5: FILL — Convergence-Based Gap Remediation

**This phase runs only when `--fix` flag is set.**

1. **Check if AGENTS.md needs regeneration.** If `context.bootstrapped === true` and gap findings include AGENTS.md coverage issues, invoke harness-knowledge-mapper (if graph available) or the directory-structure fallback to improve AGENTS.md quality.

2. **Run convergence loop** (same pattern as FIX phase):

   ```
   previousCount = context.gapFindings.length
   maxIterations = 5

   while iteration < maxIterations:
     1. Partition findings by safety
     2. Apply safe fills → verify → record
     3. Present probably-safe fills → apply approved → verify → record
     4. Surface unsafe fills to user
     5. Re-run validate-context-engineering
     6. newCount = remaining gaps (after dedup against exclusions)
     7. if newCount >= previousCount: STOP (converged)
     8. previousCount = newCount
     9. iteration++
   ```

3. **Apply safe fills silently.**
   - For `broken-link` with unambiguous target: redirect the link
   - For `undocumented` with obvious single-purpose name: add minimal entry
   - Run `harness check-docs` after each batch
   - Record in `context.fillsApplied`
   - Add filled finding IDs to `context.exclusions`

4. **Present probably-safe fills** (skip in `--ci` mode).
   - Show diff for: new file entries requiring description, AGENTS.md section reordering
   - Apply approved fills, verify, record

5. **Surface unsafe fills.**
   - Documentation for complex modules, new doc pages
   - Log for report, do not apply

6. **Record remaining unfilled gaps** for the REPORT phase.

### Phase 6: REPORT — Synthesize Health Verdict

1. **Run final `harness check-docs`** to establish the post-pipeline state.

2. **Compute verdict.**

   **FAIL if any of:**
   - Any critical drift findings remain unfixed
   - `harness check-docs` fails after all fix attempts
   - AGENTS.md does not exist and bootstrap failed

   **WARN if any of:**
   - High-priority drift or gap findings remain (user-deferred)
   - > 30% of source modules are undocumented
   - Graph not available (reduced accuracy notice)

   **PASS if:**
   - No critical or high findings remaining
   - `harness check-docs` passes
   - AGENTS.md exists and covers >70% of modules

3. **Generate per-category breakdown:**

   | Category  | Metric                                 |
   | --------- | -------------------------------------- |
   | Accuracy  | Drift findings remaining (by priority) |
   | Coverage  | Undocumented modules remaining         |
   | Links     | Broken references remaining            |
   | Freshness | Graph staleness status                 |

4. **List actions taken:**
   - Auto-fixes applied (safe): count and file list
   - User-approved fixes (probably-safe): count and file list
   - Findings deferred to user (unsafe): count and details
   - AGENTS.md bootstrapped: yes/no and method (graph or directory structure)

5. **Set context verdict and summary.** Write `context.verdict` and `context.summary`.

6. **Output report** to console. Format:

   ```
   === Documentation Health Report ===

   Verdict: PASS | WARN | FAIL

   Accuracy:  N drift findings remaining (0 critical, 0 high, N medium, N low)
   Coverage:  N/M modules documented (N%)
   Links:     N broken references remaining
   Freshness: Graph current | Graph stale (N commits behind) | No graph

   Actions:
     - N safe fixes applied silently
     - N probably-safe fixes applied (user-approved)
     - N unsafe findings deferred to user
     - AGENTS.md bootstrapped from <graph|directory structure>

   Remaining findings:
     [list of unfixed findings with priority and suggested action]
   ```

## Harness Integration

- **`harness check-docs`** — Run in DETECT, after each fix batch in FIX/FILL, and in REPORT for final state
- **`harness cleanup --type drift`** — Used by detect-doc-drift during DETECT phase
- **`harness scan`** — Used in FRESHEN to refresh stale graph
- **`harness validate`** — Run as final step in each task to verify project health

## Success Criteria

- `harness-docs-pipeline` runs all 4 sub-skills in the right order with shared context
- FIX and FILL phases iterate until converged; cascading fixes are caught
- Safe fixes are applied silently; unsafe changes surface to user
- `harness check-docs` runs after every fix batch; failed fixes are reverted
- Bootstrap handles cold start (no AGENTS.md) with graph path and directory structure fallback
- Standalone skills work independently exactly as today when invoked without pipeline context
- Entire pipeline runs without graph using static analysis fallbacks
- PASS/WARN/FAIL report includes per-category breakdown and specific remaining findings
- Drift fixes in FIX phase are excluded from AUDIT findings (no double-counting)

## Rationalizations to Reject

These are common rationalizations that sound reasonable but lead to incorrect results. When you catch yourself thinking any of these, stop and follow the documented process instead.

| "The drift finding is marked unsafe but the fix is obvious, so I will apply it silently"                      | Never apply a fix classified as unsafe without explicit user approval. The Iron Law: safe fixes are silent, unsafe fixes surface.                 |
| "The convergence loop reduced findings from 8 to 6, but the remaining ones are hard -- I will keep iterating" | If a convergence iteration does not reduce the finding count, stop immediately. Continuing without progress wastes iterations.                    |
| "I can write the drift detection logic directly instead of delegating to detect-doc-drift"                    | The pipeline delegates, never reimplements. Each sub-skill retains full standalone functionality.                                                 |
| "The graph is not available so the pipeline results will be unreliable"                                       | The entire pipeline runs without a graph using static analysis fallbacks. Reduced accuracy is noted in the report, not used as an excuse to skip. |

## Examples

### Example: Full pipeline run with fixes

```
Input: --fix flag set, graph available, AGENTS.md exists

1. FRESHEN  — Graph exists, 3 commits behind (< 10, skip refresh)
               AGENTS.md exists, no bootstrap needed
2. DETECT   — detect-doc-drift found 8 findings:
               2 critical (deleted file still referenced)
               3 high (renamed functions)
               2 medium (stale descriptions)
               1 low (formatting)
3. FIX      — Iteration 1:
                 3 safe fixes applied (renamed file paths)
                 2 probably-safe presented, 2 approved
                 2 unsafe surfaced to user
                 harness check-docs: pass
               Re-detect: 1 new finding (cascading rename)
               Iteration 2:
                 1 safe fix applied
                 Re-detect: 0 new findings — converged
4. AUDIT    — validate-context-engineering found 5 gaps
               2 already in exclusions (fixed in FIX) → 3 remaining
5. FILL     — 1 safe fill (broken link redirect)
               1 probably-safe (new module entry) → approved
               1 unsafe (complex module docs) → deferred
               Re-audit: converged
6. REPORT   — Verdict: WARN
               Accuracy: 2 drift findings remaining (0 critical, 0 high, 1 medium, 1 low)
               Coverage: 12/14 modules documented (86%)
               Links: 0 broken references
               Freshness: Graph current
```

### Example: CI mode (non-interactive)

```
Input: --fix --ci flags set, no graph

1. FRESHEN  — No graph (notice logged), AGENTS.md exists
2. DETECT   — 4 findings (1 critical, 2 high, 1 medium)
3. FIX      — 2 safe fixes applied silently
               probably-safe and unsafe: logged to report (no prompts)
4. AUDIT    — 2 gaps (1 deduped) → 1 remaining
5. FILL     — 0 safe fills, 1 probably-safe logged to report
6. REPORT   — Verdict: FAIL (1 critical finding remains)
```

### Example: Bootstrap from directory structure

```
Input: --bootstrap flag set, no graph, no AGENTS.md

1. FRESHEN  — No graph, no AGENTS.md
               Fallback bootstrap: glob src/*, read package.json
               Generated minimal AGENTS.md (32 lines)
               context.bootstrapped = true
2. DETECT   — 0 drift findings (fresh AGENTS.md, no stale refs)
3. AUDIT    — 6 gaps (4 undocumented modules, 2 missing context)
4. REPORT   — Verdict: WARN (>30% modules undocumented, no graph)
```

## Gates

- **No fix without verification.** Every fix batch must be followed by `harness check-docs`. If check fails, revert the batch.
- **No unsafe auto-apply.** Fixes classified as `unsafe` are never applied without explicit user approval. In `--ci` mode, they are logged but never applied.
- **No reimplementation of sub-skill logic.** The pipeline delegates to sub-skills. If the DETECT phase is writing drift detection code, the plan is wrong.
- **No convergence without progress.** If a convergence loop iteration does not reduce the finding count, stop immediately. Do not retry.
- **Max 5 iterations per convergence loop.** Hard cap to prevent runaway loops.

## Escalation

- **When findings exceed 50:** Focus on critical and high priority only. Defer medium and low to a follow-up run.
- **When bootstrap produces low-quality AGENTS.md:** This is expected without a graph. Log a notice recommending `harness scan` and accept the reduced quality for the current run.
- **When convergence loop does not converge within 5 iterations:** Stop the loop, log remaining findings, and proceed to the next phase. The report will reflect the unconverged state.
- **When a sub-skill fails:** Log the failure, skip the phase, and continue the pipeline. The report will note the skipped phase with a WARN or FAIL verdict.
- **When `harness check-docs` is unavailable:** Fall back to file existence checks and link validation via grep. Log a notice about reduced verification accuracy.
