User Input

$ARGUMENTS

You **MUST** consider the user input before proceeding (if not empty).

Pre-Execution Checks

**Check for extension hooks (before analysis)**:

• Check if `.specify/extensions.yml` exists in the project root.
• If it exists, read it and look for entries under the `hooks.before_analyze` key
• If the YAML cannot be parsed or is invalid, do not skip silently: tell the user that `.specify/extensions.yml` could not be read (include the parser error) and that no hooks were checked, including any mandatory (`optional: false`) hooks registered there, then continue normally
• Filter out hooks where `enabled` is explicitly `false`. Treat hooks without an `enabled` field as enabled by default.
• For each remaining hook, do **not** attempt to interpret or evaluate hook `condition` expressions:
• If the hook has no `condition` field, or it is null/empty, treat the hook as executable
• If the hook defines a non-empty `condition`, skip the hook and leave condition evaluation to the HookExecutor implementation
• When constructing command invocations from hook command names, replace dots (`.`) with hyphens (`-`). For example, `speckit.git.commit` → `/speckit-git-commit`.
• For each executable hook, output the following based on its `optional` flag:
• **Optional hook** (`optional: true`):

    ## Extension Hooks

    **Optional Pre-Hook**: {extension}
    Command: `/{command}`
    Description: {description}

    Prompt: {prompt}
    To execute: `/{command}`

• **Mandatory hook** (`optional: false`):

    ## Extension Hooks

    **Automatic Pre-Hook**: {extension}
    Executing: `/{command}`
    EXECUTE_COMMAND: {command}

    Wait for the result of the hook command before proceeding to the Goal.

After emitting the block above you MUST actually invoke the hook and wait for it to finish before continuing. Run it the same way you would run the command yourself in this agent/session (the invocation may differ from the literal `{command}` id shown above, e.g. a skills-mode agent runs it as `/skill:speckit-...` or `$speckit-...`). Emitting the block alone does not run the hook.

• If no hooks are registered or `.specify/extensions.yml` does not exist, skip silently

Goal

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`.

Operating Constraints

**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).

**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`.

Execution Steps

1. Initialize Analysis Context

Run `.specify/scripts/bash/check-prerequisites.sh --json --require-spec --require-tasks --include-tasks` once from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS. Derive absolute paths:

• SPEC = FEATURE_DIR/spec.md
• PLAN = FEATURE_DIR/plan.md
• TASKS = FEATURE_DIR/tasks.md

Abort with an error message if any required file is missing (instruct the user to run missing prerequisite command). 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").

2. Load Artifacts (Progressive Disclosure)

Load only the minimal necessary context from each artifact:

**From spec.md:**

• Overview/Context
• Functional Requirements
• Success Criteria (measurable outcomes — e.g., performance, security, availability, user success, business impact)
• User Stories
• Edge Cases (if present)

**From plan.md:**

• Architecture/stack choices
• Data Model references
• Phases
• Technical constraints

**From tasks.md:**

• Task IDs
• Descriptions
• Phase grouping
• Parallel markers [P]
• Referenced file paths

**From constitution:**

• Load `.specify/memory/constitution.md` for principle validation

3. Build Semantic Models

Create internal representations (do not include raw artifacts in output):

• **Requirements inventory**: For each Functional Requirement (FR-###) and Success Criterion (SC-###), record a stable key. Use the explicit FR-/SC- identifier as the primary key when present, and optionally also derive an imperative-phrase slug for readability (e.g., "User can upload file" → `user-can-upload-file`). Include only Success Criteria items that require buildable work (e.g., load-testing infrastructure, security audit tooling), and exclude post-launch outcome metrics and business KPIs (e.g., "Reduce support tickets by 50%").
• **User story/action inventory**: Discrete user actions with acceptance criteria
• **Task coverage mapping**: Map each task to one or more requirements or stories (inference by keyword / explicit reference patterns like IDs or key phrases)
• **Constitution rule set**: Extract principle names and MUST/SHOULD normative statements
