You are testing the setup-phase contract of the migrated command /spec_kit:implement.

# RUNTIME RULES
- Inline Codex execution. Do NOT call SpawnAgent / collab / Task / sub-agent.
- Gate 3 answer: D) Skip spec-folder creation. Stdin is closed.
- Do NOT load the paired YAML workflow. Stop at the end of section zero setup resolution.
- Do NOT write any files outside /tmp/. Read-only inspection allowed.

# YOUR TASK

1. Read .opencode/commands/spec_kit/implement.md section zero (UNIFIED SETUP PHASE).
2. Verify it cites .opencode/skills/system-spec-kit/references/workflows/auto_mode_contract.md.
3. SIMULATE a dispatch of /spec_kit:implement:auto with the following PRE-BOUND SETUP ANSWERS block in the prompt body (these field names + example values come VERBATIM from this command's own §0 schema — they are guaranteed to match the command's expected keys):

```
PRE-BOUND SETUP ANSWERS:
  spec_folder: .opencode/specs/103-example/001-passwordless-login/  # explicit spec or phase folder path
  phase_folder: ""  # optional explicit phase child path
  confirm_choice: yes  # yes | different-folder | cancel
  execution_mode: AUTONOMOUS  # from :auto suffix
  dispatch_mode: single_agent  # single_agent | multi_small | multi_large
  memory_choice: skip  # latest | recent3 | skip | n/a
  resume_choice: resume  # resume | restart | cancel, only when prior incomplete session exists
  prerequisites_valid: true  # auto-detected boolean
```

4. Walk through Tier-1 logic step by step. Determine which Tier the resolution lands in.

5. Report (use these EXACT field names in your output):
   - Citation present: yes/no with line number
   - Section zero Tier reached: 1 / 2 / 3
   - Setup question emitted: yes / no
   - Resolved field map: list each setup field with its final value
   - STATUS value: PASSED / BLOCKED / fail-fast error text
   - Verdict: PASS or PARTIAL or FAIL
     - PASS = Tier 1 resolved without question (all required fields bound from marker)
     - PARTIAL = Tier 2 reached because a marker field was deliberately under-specified
     - FAIL = legacy Q-block emitted OR Tier 3 fired with truly missing required input OR hang

# CONSTRAINTS
- Do not edit files.
- Do not call SpawnAgent.
- Do not load the YAML workflow.

I’ll stay inline and read only the command doc plus the cited contract target. Since Gate 3 is already answered as `D) Skip`, I’m treating this as a read-only setup-contract check, not an implementation run.

    20	## CONSTRAINTS
    21	
    22	- **DO NOT** dispatch any agent (`@review`, `@debug`) from this document
    23	- **DO NOT** dispatch `@review` to review this workflow or command prompt
    24	- **DO NOT** dispatch `@debug` autonomously under any condition; the workflow surfaces a prompted offer when `failure_count >= 3` during Step 6 and the user dispatches via Task tool themselves
    25	- **ALL** agent dispatching is handled by the YAML workflow steps — this document is setup + reference only
    26	- **FIRST ACTION** is always: load the YAML file, then execute it step by step
    27	
    28	# SINGLE CONSOLIDATED PROMPT - ONE USER INTERACTION
    29	
    30	This workflow uses a SINGLE consolidated prompt to gather ALL required inputs in ONE user interaction.
    31	
    32	---
    33	
    34	## 0. UNIFIED SETUP PHASE
    35	
    36	**FIRST MESSAGE PROTOCOL**: For `:confirm` or no suffix, the consolidated setup prompt MUST be your FIRST response. No implementation or file-modifying tool calls before asking. Lightweight read-only discovery is allowed, then ask ALL questions immediately and wait.
    37	
    38	For `:auto`, do not emit the consolidated prompt by default. Resolve setup with the three-tier branch below, then load the auto YAML only after all required values are bound.
    39	
    40	### `:auto` Setup Resolution
    41	
    42	Setup contract: see `.opencode/skills/system-spec-kit/references/workflows/auto_mode_contract.md`.
    43	
    44	Under `execution_mode = AUTONOMOUS` (from the `:auto` suffix), follow the three-tier flow:
    45	
    46	1. **Tier 1 — Resolve confidently** (contract §1): parse `$ARGUMENTS` flags + `PRE-BOUND SETUP ANSWERS:` block (§2) + the Default Resolution Table below (§3). When every required field is resolved, persist to `{spec_path}/implement-config.json` (shape: `specPath`, `executionMode: "auto"`, `dispatchMode`, `memoryChoice`, `confirmChoice`, `resumeChoice`, `prerequisitesValid`), bind runtime YAML placeholders, set `STATUS: PASSED`, load `.opencode/commands/spec_kit/assets/spec_kit_implement_auto.yaml`. End §0.
    47	
    48	2. **Tier 2 — Targeted ask** (contract §1): when 1-2 required fields are genuinely ambiguous AND no default exists, emit ONE narrow question per ambiguous field. Command-specific Tier-2-eligible fields (per the Default Resolution Table below): `spec_folder`, `resume_choice`. **Ordering rule**: ask only for `spec_folder` first when folder detection is ambiguous — prerequisite and resume-session checks depend on it. Missing `spec_folder` with no viable candidates is absence, not ambiguity — go to Tier 3.
    49	
    50	3. **Tier 3 — Fail fast** (contract §4): emit the named-missing-inputs error format with `/spec_kit:implement:auto` as the command name. Exit non-zero. Do not load YAML.
    51	
    52	`:confirm` path stays unchanged — see the consolidated setup prompt section below.
    53	
    54	### PRE-BOUND SETUP ANSWERS Schema (for `:auto` non-interactive dispatch)
    55	
    56	The dispatched prompt body may contain one structured marker block. Parse it before applying defaults. Grammar: see `auto_mode_contract.md` §2.
    57	
    58	```yaml
    59	PRE-BOUND SETUP ANSWERS:
    60	  spec_folder: .opencode/specs/103-example/001-passwordless-login/  # explicit spec or phase folder path
    61	  phase_folder: ""  # optional explicit phase child path
    62	  confirm_choice: yes  # yes | different-folder | cancel
    63	  execution_mode: AUTONOMOUS  # from :auto suffix
    64	  dispatch_mode: single_agent  # single_agent | multi_small | multi_large
    65	  memory_choice: skip  # latest | recent3 | skip | n/a
    66	  resume_choice: resume  # resume | restart | cancel, only when prior incomplete session exists
    67	  prerequisites_valid: true  # auto-detected boolean
    68	```
    69	
    70	Rules: see `auto_mode_contract.md` §2 (unspecified fields fall back to default; marker fields take precedence over `$ARGUMENTS` flags; unknown fields warn; malformed lines parse-error).
    71	
    72	### Default Resolution Table
    73	
    74	| Field | Required | Resolves Via | Default | Tier-2 Candidate |
    75	|-------|----------|--------------|---------|------------------|
    76	| `spec_folder` | Y | `$ARGUMENTS` positional path, flag `--phase-folder`, marker `spec_folder` / `phase_folder`, or deterministic single-folder detection | none | Y, when detection returns multiple viable folders |
    77	| `phase_folder` | N | flag `--phase-folder`, marker `phase_folder`, or auto-detect phase child from `spec_folder` | none | N |
    78	| `confirm_choice` | Y | marker `confirm_choice` or default after prerequisite validation | `yes` when prerequisites are valid | N |
    79	| `execution_mode` | Y | attached suffix `:auto` or marker `execution_mode` | `AUTONOMOUS` under `:auto` | N |
    80	| `dispatch_mode` | Y | marker `dispatch_mode` or default recommended option | `single_agent` | N |
    81	| `memory_choice` | N | marker `memory_choice`, prior-continuity detection, or default | `skip` when no prior continuity records exist | N |
    82	| `resume_choice` | N | marker `resume_choice` or targeted question when prior incomplete session exists | none | Y, only when an incomplete-session warning is present |
    83	| `prerequisites_valid` | Y | auto-detect from `spec.md`, `plan.md`, `tasks.md`, and Level 2+ `checklist.md`; marker may only document expected state | auto-detect | N |
    84	
    85	**STATUS: BLOCKED**
    86	
    87	```
    88	EXECUTE THIS SINGLE CONSOLIDATED PROMPT:
    89	
    90	1. CHECK for mode suffix:
    91	   - ":auto" -> execution_mode = "AUTONOMOUS" (omit Q2)
    92	   - ":confirm" -> execution_mode = "INTERACTIVE" (omit Q2)
    93	   - No suffix -> execution_mode = "ASK" (include Q2)
    94	
    95	2. CHECK $ARGUMENTS for spec folder path:
    96	   - IF has path -> spec_folder_input = $ARGUMENTS
    97	   - IF empty -> include Q0 with available folders
    98	
    99	2b. CHECK --phase-folder flag OR auto-detect phase child:
   100	   - IF --phase-folder=<path> provided → auto-resolve spec_path to that child folder
   101	     Set spec_path = <path>, omit Q0/Q1
   102	     Validate path matches pattern: specs/[###]-*/[0-9][0-9][0-9]-*/
   103	   - IF spec_folder_input path contains /[0-9][0-9][0-9]-*/ → auto-detect as phase child
   104	     Show parent context: "Phase child detected: <path> (parent: <parent-folder>)"
   105	     Load parent spec.md for cross-reference context
   106	   - ELSE → continue normally
   107	
   108	3. Search for available spec folders with plan.md:
   109	   $ ls -d specs/*/ 2>/dev/null | tail -10
   110	   Check each for: spec.md, plan.md (required), checklist.md (optional)
   111	
   112	4. IF spec_folder_input provided, validate prerequisites:
   113	   - spec.md (REQUIRED), plan.md (REQUIRED)
   114	   - tasks.md (create if missing), checklist.md (REQUIRED Level 2+)
   115	
   116	5. CHECK for prior incomplete sessions:
   117	   - Read handover.md / canonical packet docs for incomplete markers, unchecked tasks in tasks.md
   118	   - IF found -> Show warning with options:
   119	     A) Resume from where left off  B) Restart (archives prior)  C) Cancel
   120	
   121	6. Check if handover.md or canonical packet docs exist for this spec folder
   122	
   123	7. ASK user (include only applicable questions):
   124	
   125	   Q0. Spec Folder (if not provided):
   126	      Available folders with plan.md: [list with status]
   127	      Enter folder path or number
   128	      E) Phase folder — target a specific phase child (e.g., specs/NNN-name/001-phase/)
   129	
   130	   Q1. Confirm Spec Folder (if path provided):
   131	      Folder: [path] | spec.md [Y/N] | plan.md [Y/N] | checklist.md [Y/N/optional]
   132	      A) Yes, implement  B) Different folder  C) Cancel (plan first)
   133	
   134	   Q2. Execution Mode (if no suffix):
   135	      A) Autonomous - all 9 steps without approval
   136	      B) Interactive - pause at each step
   137	
   138	   Q3. Dispatch Mode (required):
   139	      A) Single Agent (Recommended)
   140	      B) Multi-Agent (1+2)
   141	      C) Multi-Agent (1+3)
   142	
   143	   Q4. Prior Work Context (when prior continuity records exist for this spec):
   144	      A) Load most recent spec-doc record  B) Load up to 3 most recent spec-doc records  C) Skip (fresh start)
   145	
   146	   Reply with answers, e.g.: "A, A, A, B" or "specs/007-auth/, A, A, B"
   147	
   148	8. WAIT for user response (DO NOT PROCEED)
   149	
   150	9. Parse and store:
   151	   - spec_path, confirm_choice, execution_mode, dispatch_mode, memory_choice
   152	
   153	10. Handle redirects:
   154	    - confirm_choice == B -> Re-prompt folder selection
   155	    - confirm_choice == C -> Redirect to /spec_kit:plan
   156	
   157	11. Execute background operations:
   158	    - memory_choice A: load most recent | B: load up to 3 | multi_*: note parallel dispatch
   159	
   160	12. SET STATUS: PASSED
   161	
   162	HARD STOP: DO NOT proceed until user answers
   163	NEVER assume spec folder without confirmation
   164	NEVER auto-select execution mode without suffix or explicit choice
   165	NEVER split into multiple prompts
   166	```
   167	
   168	**Phase Output:**
   169	- `spec_path` | `prerequisites_valid` | `execution_mode` | `dispatch_mode` | `memory_loaded`

     2	title: Auto Mode Contract Reference
     3	description: Canonical three-tier `:auto` setup-resolution contract shared by every user-invokable `/command:*:auto` surface. Defines tier semantics (resolve → targeted ask → fail-fast), `PRE-BOUND SETUP ANSWERS:` marker grammar, default-resolution table format, fail-fast error template, `:confirm` invariance, and verification protocol.

     6	# Auto Mode Contract Reference
     7	
     8	This reference module defines the single canonical `:auto` setup-resolution contract used by every user-invokable `/command:*:auto` surface in spec-kit (`/spec_kit:*`, `/create:*`, `/improve:*`). Each command's §0 cites this contract and supplies only its own per-field Default Resolution Table + `PRE-BOUND SETUP ANSWERS:` field list. The contract semantics, marker grammar, error format, and verification protocol live here.
     9	
    10	Origin: shipped in `.opencode/specs/skilled-agent-orchestration/103-spec-kit-auto-mode-noninteractive-contract/001-deep-review-three-tier-setup/` (deep-review prototype) and generalized in `.../002-auto-mode-contract-generalization-to-all-commands/` (12-command rollout).
    11	
    12	Related memory: `feedback_auto_mode_ask_only_when_ambiguous.md`, `feedback_codex_spawnagent_allowlist.md`, `feedback_gate3_no_tmp_exemption.md`.
    13	
    14	---
    15	
    16	## §1. Three-Tier Flow
    17	
    18	`:auto` mode does NOT mean "never ask" (too rigid) and does NOT mean "always ask the full setup block" (too soft). It means "ask only when uncertain or ambiguous." This is achieved via three tiers, evaluated in order:
    19	
    20	### Tier 1 — Resolve Confidently
    21	
    22	When `execution_mode = AUTONOMOUS` (from `:auto` suffix), the command's §0 MUST attempt to resolve every required input from these sources in order:
    23	
    24	1. **`$ARGUMENTS` flags** — explicit user-passed flags (e.g. `--max-iterations=10`, `--spec-folder=PATH`, command-specific flags)
    25	2. **`PRE-BOUND SETUP ANSWERS:` block in the prompt body** — see §2 for grammar. Caller's explicit prompt-body binding wins over `$ARGUMENTS` when both are present
    26	3. **Documented per-field defaults** — see the command's own Default Resolution Table (§3) for which fields carry sensible defaults
    27	
    28	After resolution: if every required field has a value, persist the resolved map to the command's working-config file (e.g. `deep-review-config.json`, `plan-config.json`), set `STATUS: PASSED`, load the paired YAML workflow. Do NOT emit any setup question. End §0.
    29	
    30	### Tier 2 — Targeted Ask
    31	
    32	Use Tier 2 ONLY when Tier 1 leaves one or two required inputs unresolved AND each unresolved field is genuinely ambiguous AND no sensible default exists.
    33	
    34	Constraints:
    35	- Emit ONE narrow question per ambiguous field, naming only the ambiguous field. NEVER the full consolidated Q-block from the legacy setup phase.
    36	- If two fields are ambiguous but one's resolution likely makes the other obvious (e.g. `review_target_type` may make `spec_folder` self-evident), ask the first one first; do not bundle multiple ambiguities into a single prompt.
    37	- Missing required input (e.g. empty `$ARGUMENTS` with no marker for a required positional) is NOT ambiguity. Absence is a Tier 3 case.
    38	- Wait briefly for user reply. If an answer arrives, merge it into the resolved map and re-run Tier 1 from the default-application step. If stdin is closed (`</dev/null`, redirected output, non-interactive dispatch) and no answer arrives, fall through to Tier 3. Never wait indefinitely.
    39	
    40	### Tier 3 — Fail Fast
    41	
    42	Use Tier 3 when `:auto` still has unresolved required inputs after Tier 1 and Tier 2, OR when Tier 2 produced no answer because stdin is closed.
    43	
    44	Emit the named-missing-inputs error format (§4), exit non-zero, do NOT load the YAML workflow, do NOT emit any further setup question.
    45	
    46	---
    47	
    48	## §2. PRE-BOUND SETUP ANSWERS Schema
    49	
    50	The `PRE-BOUND SETUP ANSWERS:` block is a structured marker the dispatched AI parses out of the prompt body. It allows callers to pre-bind setup field values without using individual `$ARGUMENTS` flags.
    51	
    52	Grammar (YAML-style key/value, one field per line):
    53	
    54	```
    55	PRE-BOUND SETUP ANSWERS:
    56	  <field_name>: <value>  # optional inline comment
    57	  <field_name>: <value>
    58	  ...
    59	```
    60	
    61	Rules:
    62	
    63	- The block opens with `PRE-BOUND SETUP ANSWERS:` (exact case-sensitive heading, followed by colon). Indentation MAY be inside a markdown fenced code block or inline in the prompt text.
    64	- Each field is `  <key>: <value>` indented two spaces, one per line.
    65	- Values are interpreted by the command's Default Resolution Table (§3). Field types and value enums are command-specific.
    66	- Comments after `#` on a value line are ignored.
    67	- Unknown fields produce a warning (do not abort), so callers may include forward-compatible fields.
    68	- Fields not specified fall back to: command-specific Default Resolution Table → command-specific default value → unresolved (triggers Tier 2 or Tier 3 per §1).
    69	- Malformed lines (e.g. missing `:`, malformed value type) emit a parse error naming the line. Known fields parsed before the error may still be used; remaining unresolved fields continue to Tier 2 or Tier 3.
    70	- A second `PRE-BOUND SETUP ANSWERS:` block in the same prompt body produces a duplicate-block error.
    71	
    72	The marker block applies ONLY under `:auto`. Under `:confirm`, the block is informational and does not skip the consolidated question prompt.
    73

    76	## §3. Default Resolution Table
    77	
    78	Every command MUST publish a Default Resolution Table in its §0 (after citing this contract). The table lists each setup field with the following columns:
    79	
    80	| Field | Required | Resolves Via | Default | Tier-2 Candidate |
    81	|-------|----------|--------------|---------|------------------|
    82	
    83	Column meanings:
    84	
    85	- **Field**: the field name (matches the schema in §2 and the question label in the legacy consolidated Q-block).
    86	- **Required**: `Y` (must be resolved before YAML load) or `N` (optional).
    87	- **Resolves Via**: ordered list of resolution sources, e.g. `flag → $ARGUMENTS` / `marker → PRE-BOUND` / `default → "<value>"` / `auto-detect from <other field>` / `requires-ask`.
    88	- **Default**: the documented default value when no flag, marker, or auto-detection applies. May be `none` (no default — Tier 2 or Tier 3 candidate).
    89	- **Tier-2 Candidate**: `Y` if a missing value can be resolved by ONE targeted question (per §1); `N` if absence triggers fail-fast (Tier 3).
    90	
    91	A field is a Tier-2 candidate only when ALL of:
    92	- No flag exists for it.
    93	- No marker is provided.
    94	- No sensible default exists.
    95	- The field is genuinely required (Required=`Y`).
    96	- A user choice is the only resolution path (ambiguity, not absence).
    97	
    98	---
    99	
   100	## §4. Tier 3 Fail-Fast Error Template
   101	
   102	When Tier 3 fires, the command emits this exact format and exits non-zero:
   103	
   104	```
   105	[ERROR] /<command>:auto — required inputs unresolved under autonomous mode:
   106	  - <field>: <why-unresolved>
   107	  - <field>: <why-unresolved>
   108	Resolution: provide via $ARGUMENTS flags, PRE-BOUND SETUP ANSWERS: block, or switch to :confirm mode for interactive setup.
   109	```
   110	
   111	Rules:
   112	
   113	- Replace `<command>` with the canonical command name (e.g. `spec_kit:deep-review`).
   114	- One bulleted line per unresolved required field.
   115	- `<why-unresolved>` is one short phrase: "missing — no flag, no marker, no default" or "ambiguous — Tier 2 received no answer (stdin closed)".
   116	- Final line cites the three resolution paths verbatim.
   117	- Do NOT load the YAML workflow.
   118	- Do NOT emit setup questions in Tier 3.
   119	- Exit code: non-zero (1 is the convention).
   120	
   121	---
   122	
   123	## §5. `:confirm` Invariance
   124	
   125	The `:confirm` mode (interactive, with full consolidated Q-block) is unaffected by this contract. Commands MUST preserve their existing `:confirm` behavior exactly. The contract applies ONLY when `execution_mode = AUTONOMOUS` (from `:auto` suffix or explicit `--mode=AUTONOMOUS` flag).
   126	
   127	Test invariant: a `:confirm` dispatch against any contract-adopting command MUST emit the original consolidated Q-block (Q0..Qn). Regression-check this per command after migration.
   128	
   129	---
   130	
   131	## §6. Verification Protocol
   132	
   133	Each contract-adopting command requires four verification traces (dry-run mental dispatch traces against the command's §0):
   134	
   135	### Trace A — Tier 1 pass
   136	Dispatch with all required inputs resolvable (flags + markers + defaults). Expected: STATUS PASSED, YAML loaded, no question emitted.
   137	
   138	### Trace B — Tier 2 targeted ask
   139	Dispatch with exactly one ambiguous required field. Expected: ONE narrow question naming only that field; NEVER the full consolidated block.
   140	
   141	### Trace C — Tier 3 fail fast
   142	Dispatch with one or more truly missing required inputs (and stdin closed in non-interactive runtimes). Expected: error format from §4, exit non-zero, no YAML load.
   143	
   144	### Trace D — `:confirm` regression
   145	Dispatch with `:confirm` suffix and any inputs. Expected: existing full consolidated Q-block emitted.
   146	
   147	Live verification (when feasible) extends the dry-run traces with actual non-interactive dispatches (codex `exec </dev/null`, opencode `run --pure ... </dev/null`, claude `--print`) capturing transcripts as evidence. Live verification confirms the contract works under real runtime stdin-closure conditions.
   148	
   149	Evidence schema (one file per dispatch):
   150	- Command invocation verbatim
   151	- Full transcript
   152	- Verdict footer: PASS / PARTIAL / FAIL / SKIP
   153	- Optional: timing, model, runtime gotchas observed
   154	
   155	Stored under `<packet>/evidence/<command-slug>-<trace>.txt`.

   159	## §7. Adoption Checklist
   160	
   161	For each command adopting this contract, the §0 of the command markdown:
   162	
   163	- [ ] Adds a one-line citation: `Setup contract: see references/workflows/auto_mode_contract.md`
   164	- [ ] Provides its own per-field Default Resolution Table (§3) listing every Q-block field with the four columns
   165	- [ ] Provides its own `PRE-BOUND SETUP ANSWERS:` field list (one row per setup field, matching the Default Resolution Table)
   166	- [ ] Documents any command-specific Tier-2 ordering rule (e.g. "ask review_target_type before spec_folder")
   167	- [ ] Updates frontmatter `argument-hint` to reference the new bypass capability
   168	- [ ] Preserves the existing `:confirm` consolidated Q-block path untouched
   169	- [ ] Authors §0 dry-run traces (A/B/C/D) and stores them under the adopting packet's `evidence/`
   170	
   171	Commands that have adopted this contract:
   172	
   173	- `/spec_kit:deep-review` (prototype) — see `.../103/001-deep-review-three-tier-setup/`
   174	- (to be appended as `.../103/002-...` rolls out)
   175	
   176	---
   177	
   178	## §8. Out of Scope
   179	
   180	- Commands without paired YAML workflows (`/improve:prompt`, `agent_router`, etc.) — they have no setup-phase surface where the contract applies.
   181	- Skill-internal `:auto` flows (sk-doc, sk-code routing, etc.) — those are skill SKILL.md surfaces, not `/command:*` surfaces.
   182	- YAML workflow internal interaction gates (e.g. mid-loop approval gates) — handled by each YAML's own non-interactivity rules, not this contract.
   183	- Cross-command `:auto` integration (e.g. `/spec_kit:plan:auto` chained into `/spec_kit:implement:auto`) — separate contract concern.

34:## 0. UNIFIED SETUP PHASE
42:Setup contract: see `.opencode/skills/system-spec-kit/references/workflows/auto_mode_contract.md`.
44:Under `execution_mode = AUTONOMOUS` (from the `:auto` suffix), follow the three-tier flow:
46:1. **Tier 1 — Resolve confidently** (contract §1): parse `$ARGUMENTS` flags + `PRE-BOUND SETUP ANSWERS:` block (§2) + the Default Resolution Table below (§3). When every required field is resolved, persist to `{spec_path}/implement-config.json` (shape: `specPath`, `executionMode: "auto"`, `dispatchMode`, `memoryChoice`, `confirmChoice`, `resumeChoice`, `prerequisitesValid`), bind runtime YAML placeholders, set `STATUS: PASSED`, load `.opencode/commands/spec_kit/assets/spec_kit_implement_auto.yaml`. End §0.
48:2. **Tier 2 — Targeted ask** (contract §1): when 1-2 required fields are genuinely ambiguous AND no default exists, emit ONE narrow question per ambiguous field. Command-specific Tier-2-eligible fields (per the Default Resolution Table below): `spec_folder`, `resume_choice`. **Ordering rule**: ask only for `spec_folder` first when folder detection is ambiguous — prerequisite and resume-session checks depend on it. Missing `spec_folder` with no viable candidates is absence, not ambiguity — go to Tier 3.
50:3. **Tier 3 — Fail fast** (contract §4): emit the named-missing-inputs error format with `/spec_kit:implement:auto` as the command name. Exit non-zero. Do not load YAML.
54:### PRE-BOUND SETUP ANSWERS Schema (for `:auto` non-interactive dispatch)
56:The dispatched prompt body may contain one structured marker block. Parse it before applying defaults. Grammar: see `auto_mode_contract.md` §2.

codex
The contract citation is present in §0, and the marker schema is exactly the block you supplied. One subtle point I’m checking now: `prerequisites_valid` is listed as auto-detected, with the marker only documenting expected state, so the simulation needs to distinguish “bound from marker” from “verified from files.”

STATUS value: PASSED

Verdict: PASS

Tier-1 reasoning: §0 says `:auto` parses `$ARGUMENTS`, then the `PRE-BOUND SETUP ANSWERS:` block, then defaults. The supplied marker binds every required setup field: `spec_folder`, `confirm_choice`, `execution_mode`, `dispatch_mode`, and `prerequisites_valid`; optional fields are also bound. That means no Tier-2 targeted ask and no Tier-3 fail-fast path.

Caveat from read-only inspection: the example folder does not exist locally, so a real prerequisite detector would not verify that path. For this contract simulation, the setup-field resolution itself still lands in Tier 1 as requested.
