Consolidates all ACs from PRD, TechSpec, and Tasks, presents to user for confirmation, and saves the locked AC list to accepted-criteria.md. Implementation only starts after explicit user confirmation.\n---\n\n# AC Lock Checkpoint\n\nRuns **automatically as Phase 4.0**, after Tasks Validation and before the first implementation task.\nPurpose: give the user one final explicit confirmation that the Acceptance Criteria represent what they actually want — before any implementation begins.\n\n## Position in flow\n\n```\n[Tasks Validation]\n      ↓\n[AC Lock Checkpoint]  ← THIS SKILL\n      ↓\nPer-Task: implementation\n```\n\n## Entry conditions\n\n- `prd.md`, `techspec.md`, and `tasks.md` must exist in `tasks/prd-{slug}/`\n- Generates `accepted-criteria.md` in `.claude/feature-state/{slug}/`\n- If `accepted-criteria.md` already exists (resume case): skip extraction, ask user to confirm current locked ACs or unlock to re-confirm\n- Implementation **must not start** until this file is saved\n\n---\n\n## Step 1: Extract and Consolidate ACs\n\n### Sources\n\nRead ACs from all three documents:\n\n**From `prd.md`:**\n- \"Goals\" or \"Objectives\" section (functional success criteria)\n- \"Acceptance Criteria\" section (if present)\n- \"Success Metrics\" section (if present)\n\n**From `techspec.md`:**\n- \"Validation & Testing Plan\" section\n- \"Acceptance Criteria\" section (if present)\n- Non-functional requirements that can be verified\n\n**From `tasks.md`:**\n- \"Acceptance Criteria\" or \"Done When\" column/field per task\n- Any inline criteria in task descriptions\n\n### Deduplication\n\nMerge near-duplicate ACs (same intent, slightly different wording):\n- \"trainerId is saved to Firestore\" + \"trainerId is persisted on student document\" → consolidate as one\n- Use the more specific/verifiable version\n\n### Classification\n\nGroup ACs into three categories:\n\n1. **Functional** — observable user/system behavior\n   - e.g., \"Trainer can see their connected students in /cms/students\"\n\n2. **Technical** — implementation-level verifiable criteria\n   - e.g., \"POST /api/students saves trainerId field\"\n   - e.g., \"Firestore security rules validated\"\n\n3. **Quality** — non-functional, cross-cutting\n   - e.g., \"All use cases have unit tests\"\n   - e.g., \"No breaking changes to existing API consumers\"\n\n---\n\n## Step 2: Present to User\n\nPresent the consolidated list with clear formatting before any implementation starts:\n\n```\n✋ AC Lock Checkpoint — Confirm Before Implementation\n\nThis feature will be considered DONE when all of the following are true:\n\n**Functional**\n1. [ ] Personal trainer can see all linked students in /cms/students\n2. [ ] Student appears in trainer's list after successful Firestore connection\n3. [ ] trainerId is persisted on student document in Firestore\n\n**Technical**\n4. [ ] POST /api/students saves trainerId field from auth context\n5. [ ] GET /api/students filters by authenticated trainer's uid\n6. [ ] Firestore security rules allow trainer to read their students only\n\n**Quality**\n7. [ ] All new use cases have unit tests\n8. [ ] No breaking changes to existing /api/students consumers\n\n---\n\nDoes this accurately capture what you want?\n\n  yes           → Lock these ACs and start implementation\n  adjust N      → Edit AC number N (e.g., \"adjust 3\")\n  add           → Add a missing AC\n  remove N      → Remove AC number N\n  show-sources  → Show which document each AC came from\n```\n\n---\n\n## Step 3: Interactive Adjustment\n\nAllow the user to modify the AC list before locking:\n\n### \"adjust N\" — edit one AC\n\n```\nCurrent AC-3: \"trainerId is persisted on student document in Firestore\"\nNew AC-3: [user input]\n```\n\nReplace the AC in the list and re-present the relevant section.\n\n### \"add\" — add a missing AC\n\n```\nEnter new AC (describe what must be true when the feature is done):\n[user input]\n\nCategory: functional / technical / quality?\n```\n\nAppend to the appropriate category.\n\n### \"remove N\" — remove an AC\n\n```\nRemoving AC-5: \"GET /api/students filters by authenticated trainer's uid\"\nAre you sure? This requirement won't be tracked. (yes/no)\n```\n\n### \"show-sources\" — show provenance\n\n```\nAC-1 → prd.md: Goals section\nAC-4 → techspec.md: Validation & Testing Plan\nAC-7 → tasks.md: Task 6 - \"Done When\" criteria\n```\n\n---\n\n## Step 4: Lock and Persist\n\nAfter user confirms with `yes`:\n\nSave to `.claude/feature-state/{slug}/accepted-criteria.md`:\n\n```markdown\n## Accepted Criteria — Locked\n\nFeature: {slug}\nLocked: {timestamp}\nLocked by: user confirmation\n\n> ⚠️ This file is immutable during implementation.\n> Do not edit after locking.\n\n### Functional\n- [ ] AC-1: Personal trainer can see all linked students in /cms/students\n- [ ] AC-2: Student appears in trainer's list after successful Firestore connection\n- [ ] AC-3: trainerId is persisted on student document in Firestore\n\n### Technical\n- [ ] AC-4: POST /api/students saves trainerId field from auth context\n- [ ] AC-5: GET /api/students filters by authenticated trainer's uid\n- [ ] AC-6: Firestore security rules allow trainer to read their students only\n\n### Quality\n- [ ] AC-7: All new use cases have unit tests\n- [ ] AC-8: No breaking changes to existing /api/students consumers\n\n### Sources\n| AC | Source |\n|----|--------|\n| AC-1 | prd.md: Goals |\n| AC-4 | techspec.md: Validation & Testing Plan |\n| AC-7 | tasks.md: Task 6 |\n```\n\n---\n\n## Step 5: PR Coverage Verification\n\nDuring Phase 5 (Commit & PR), read `accepted-criteria.md` and check which ACs are covered:\n\n### Coverage check\n\nFor each AC, check if implementation tasks have been completed that address it:\n- Match tasks marked ✅ in the task list against AC keywords\n- Mark covered ACs as `[x]` in the coverage report\n\n### PR description includes\n\n```markdown\n## Definition of Done\n\n**Covered by this PR:**\n- [x] AC-1: Personal trainer can see all linked students in /cms/students\n- [x] AC-2: Student appears in trainer's list after Firestore connection\n- [x] AC-4: POST /api/students saves trainerId field\n\n**Known gaps (not covered):**\n- [ ] AC-7: Unit tests — partial (3 of 5 use cases tested)\n\n> Full AC list: .claude/feature-state/{slug}/accepted-criteria.md\n```\n\nIf all ACs are covered → no \"Known gaps\" section.\n\n---\n\n## Behavior Summary\n\n| State | Behavior |\n|-------|----------|\n| `accepted-criteria.md` does not exist | Run full AC Lock flow |\n| File exists, `--resume` flag | Show locked ACs, ask to confirm or unlock |\n| File exists, `--force-relock` flag | Re-run extraction, allow new confirmation |\n| User skips (emergency) | Warn, log \"AC Lock bypassed\", proceed without file |\n\n### Emergency bypass\n\nIf the user explicitly wants to skip AC Lock (e.g., rapid prototype):\n```\n⚠️ AC Lock bypassed — implementation will proceed without locked ACs.\n   PR will not include a \"Definition of Done\" section.\n   Type \"skip-ac-lock\" to confirm.\n```\n\nLog the bypass in `.claude/feature-state/{slug}/checkpoint.json`.\n","tagline":"Phase 4.0 — Acceptance Criteria lock checkpoint before implementation.
