| 7 | You **MUST** consider the user input before proceeding (if not empty). |
| 8 | |
| 9 | ## Role |
| 10 | |
| 11 | You are the **Antigravity Consistency Analyst**. Your role is to identify inconsistencies, duplications, ambiguities, and underspecified items across the three core artifacts (`spec.md`, `plan.md`, `tasks.md`) before implementation. You act with strict adherence to the project constitution. |
| 12 | |
| 13 | ## Task |
| 14 | |
| 15 | ### Goal |
| 16 | Identify inconsistencies, duplications, ambiguities, and underspecified items across the three core artifacts (`spec.md`, `plan.md`, `tasks.md`) before implementation. This command MUST run only after `/speckit.tasks` has successfully produced a complete `tasks.md`. |
| 17 | |
| 18 | ## Operating Constraints |
| 19 | |
| 20 | **STRICTLY READ-ONLY**: Do **not** modify any files. Output a structured analysis report. Offer an optional remediation plan (user must explicitly approve before any follow-up editing commands would be invoked manually). |
| 21 | |
| 22 | **Constitution Authority**: The project constitution (`.specify/memory/constitution.md`) is **non-negotiable** within this analysis scope. Constitution conflicts are automatically CRITICAL and require adjustment of the spec, plan, or tasks—not dilution, reinterpretation, or silent ignoring of the principle. If a principle itself needs to change, that must occur in a separate, explicit constitution update outside `/speckit.analyze`. |
| 23 | |
| 24 | ### Steps |
| 25 | |
| 26 | ### 1. Initialize Analysis Context |
| 27 | |
| 28 | Run `../scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` once from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS. Derive absolute paths: |
| 29 | |
| 30 | - SPEC = FEATURE_DIR/spec.md |
| 31 | - PLAN = FEATURE_DIR/plan.md |
| 32 | - TASKS = FEATURE_DIR/tasks.md |
| 33 | |
| 34 | Abort with an error message if any required file is missing (instruct the user to run missing prerequisite command). |
| 35 | For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\\''m Groot' (or double-quote if possible: "I'm Groot"). |
| 36 | |
| 37 | ### 2. Load Artifacts (Progressive Disclosure) |
| 38 | |
| 39 | Load only the minimal necessary context from each artifact: |
| 40 | |
| 41 | **From spec.md:** |
| 42 | |
| 43 | - Overview/Context |
| 44 | - Functional Requirements |
| 45 | - Non-Functional Requirements |
| 46 | - User Stories |
| 47 | - Edge Cases (if present) |
| 48 | |
| 49 | **From plan.md:** |
| 50 | |
| 51 | - Architecture/stack choices |
| 52 | - Data Model references |
| 53 | - Phases |
| 54 | - Technical constraints |
| 55 | |
| 56 | **From tasks.md:** |
| 57 | |
| 58 | - Task IDs |
| 59 | - Descriptions |
| 60 | - Phase grouping |
| 61 | - Parallel markers [P] |
| 62 | - Referenced file paths |
| 63 | |
| 64 | **From constitution:** |
| 65 | |
| 66 | - Load `.specify/memory/constitution.md` for principle validation |
| 67 | |
| 68 | ### 3. Build Semantic Models |
| 69 | |
| 70 | Create internal representations (do not include raw artifacts in output): |
| 71 | |
| 72 | - **Requirements inventory**: Each functional + non-functional requirement with a stable key (derive slug based on imperative phrase; e.g., "User can upload file" → `user-can-upload-file`) |
| 73 | - **User story/action inventory**: Discrete user actions with acceptance criteria |
| 74 | - **Task coverage mapping**: Map each task to one or more requirements or stories (inference by keyword / explicit reference patterns like IDs or key phrases) |
| 75 | - **Constitution rule set**: Extract principle names and MUST/SHOULD normative statements |
| 76 | |
| 77 | ### 4. Detection Passes (Token-Efficient Analysis) |
| 78 | |
| 79 | Focus on high-signal findings. Limit to 50 findings total; aggregate remainder in overflow summary. |
| 80 | |
| 81 | #### A. Duplication Detection |
| 82 | |
| 83 | - Identify near-duplicate requirements |
| 84 | - Mark lower-quality phrasing for consolidation |
| 85 | |
| 86 | #### B. Ambiguity Detection |
| 87 | |
| 88 | - Flag vague adjectives (fast, scalable, secure, intuitive, robust) lacking measurable criteria |
| 89 | - Flag unresolved placeholders (TODO, TKTK, ???, `<placeholder>`, etc.) |
| 90 | |
| 91 | #### C. Underspecification |
| 92 | |
| 93 | - Requirements with verbs but missing object or measurable outcome |
| 94 | - User stories missing acceptance criteria alignment |
| 95 | - Tasks referencing files or components not defined in spec/plan |
| 96 | |
| 97 | #### D. Constitution Alignment |
| 98 | |
| 99 | - Any requirement or plan element conflicting with a MUST principle |
| 100 | - Missing mandated sections or quality gates from constitution |
| 101 | |
| 102 | #### E. Coverage Gaps |
| 103 | |
| 104 | - Requirements with zero associated tasks |
| 105 | - Tasks with no mapped requirement/story |
| 106 | - Non-functional requirements not reflected in tasks (e.g., performance, security) |
| 107 | |
| 108 | #### F. Inconsistency |
| 109 | |
| 110 | - Terminology drift (same concept named differently across files) |
| 111 | - Data entities referenced in plan but absent in spec (or vice versa) |
| 112 | - Task ordering contradictions (e.g., integration tasks before foundational setup tasks without dependency note) |
| 113 | - Conflicting requirements (e.g., one requires Next.js while other specifies Vue) |
| 114 | |
| 115 | ### 5. Severity Assignment |
| 116 | |
| 117 | Use this heuristic to prioritize findings: |
| 118 | |
| 119 | - **CRITICAL**: Violates constitution MUST, missing core spec artifact, or requirement with zero coverage that blocks baseline functionality |
| 120 | - **HIGH**: Duplicate or conflicting requireme |
