Checklist Purpose: "Unit Tests for English"

CRITICAL CONCEPT: Checklists are UNIT TESTS FOR REQUIREMENTS WRITING — they validate the quality, clarity, and completeness of requirements in a given domain. If your spec is code written in English, the checklist is its unit test suite: you test whether the requirements are well-written, complete, unambiguous, and ready for implementation — NOT whether the implementation works.

NOT for verification/testing:

• ❌ NOT "Verify the button clicks correctly"
• ❌ NOT "Test error handling works"
• ❌ NOT "Confirm the API returns 200"
• ❌ NOT checking if code/implementation matches the spec

FOR requirements quality validation:

• ✅ "Are visual hierarchy requirements defined for all card types?" (completeness)
• ✅ "Is 'prominent display' quantified with specific sizing/positioning?" (clarity)
• ✅ "Are hover state requirements consistent across all interactive elements?" (consistency)
• ✅ "Are accessibility requirements defined for keyboard navigation?" (coverage)
• ✅ "Does the spec define what happens when logo image fails to load?" (edge cases)

User Input

$ARGUMENTS

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

Pre-Execution Checks

Check for extension hooks (before checklist generation):

• Discover hooks across all extension files (multi-file discovery), not just the central file:
  • Read .specify/extensions.yml from the project root (if present) and collect entries under the hooks.before_checklist key.
  • Then enumerate every .specify/extensions/*/*.yml file in sorted order, parse each, and collect its hooks.before_checklist entries too — so a hook registered only in a per-extension file (e.g. the feedback extension at .specify/extensions/feedback/feedback.yml) is still discovered and runs.
  • Merge all collected entries and dedupe by (extension, command) (first occurrence wins, so a hook declared in both files runs once).
  • If a file is absent, no hooks are registered, or its YAML cannot be parsed/is invalid, skip that file silently and continue.
• For every optional: true hook that is discovered but not executed this phase, emit one line so the skip is a visible decision: Note: optional hook {extension}:{command} is registered but was not run (skipped).
• Filter out hooks where enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
• Do not 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
• 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 Execution Steps.
    

Execution Steps

1. Setup: Run .specify/scripts/bash/check-prerequisites.sh --json from repo root and parse JSON for FEATURE_DIR and AVAILABLE_DOCS list.

   • All file paths must be absolute.
   • 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. Clarify intent (dynamic): Derive up to THREE initial contextual clarifying questions (no pre-baked catalog). They MUST:

   • Be generated from the user's phrasing + extracted signals from spec/plan/tasks
   • Only ask about information that materially changes checklist content
   • Be skipped individually if already unambiguous in $ARGUMENTS
   • Prefer precision over breadth (do not ask the user to restate what they already said)

   Generation algorithm:

   1. Extract signals: feature domain keywords (e.g., auth, latency, UX, API), risk indicators ("critical", "must", "compliance"), stakeholder hints ("QA", "review", "security team"), and explicit deliverables ("a11y", "rollback", "contracts").
   2. Cluster signals into candidate focus areas (max 4) ranked by relevance.
   3. Identify probable audience & timing (author, reviewer, QA, release) if not explicit.
   4. Detect missing dimensions: scope breadth, depth/rigor, risk emphasis, exclusion boundaries, measurable acceptance criteria.
   5. Formulate questions chosen from these archetypes:
      • Scope refinement (e.g., "Should this include integration touchpoints with X and Y or stay limited to local module correctness?")
      • Risk prioritization (e.g., "Which of these potential risk areas should receive mandatory gating checks?")
      • Depth calibration (e.g., "Is this a lightweight pre-commit sanity list or a formal release gate?")
      • Audience framing (e.g., "Will this be used by the author only or peers during PR review?")
      • Boundary exclusion (e.g., "Should we explicitly exclude performance tuning items this round?")
      • Scenario class gap (e.g., "No recovery flows detected—are rollback / partial failure paths in scope?")

   Question formatting rules:

   • If presenting options, generate a compact table with columns: Option | Candidate | Why It Matters
   • Limit to A–E options maximum; omit table if a free-form answer is clearer
   • Avoid speculative categories (no hallucination). If uncertain, ask explicitly: "Confirm whether X belongs in scope."

   Defaults when interaction impossible:

   • Depth: Standard
   • Audience: Reviewer (PR) if code-related; Author otherwise
   • Focus: Top 2 relevance clusters

   Output the questions (label Q1/Q2/Q3). After answers: if ≥2 scenario classes (Alternate / Exception / Recovery / Non-Functional domain) remain unclear, you MAY ask up to TWO more targeted follow‑ups (Q4/Q5) with a one-line justification each (e.g., "Unresolved recovery path risk"). Do not exceed five total questions. Skip escalation if user explicitly declines more.

3. Understand user request: Combine $ARGUMENTS + clarifying answers:

   • Derive checklist theme (e.g., security, review, deploy, ux)
   • Consolidate explicit must-have items mentioned by user
   • Map focus selections to category scaffolding
   • Infer any missing context from spec/plan/tasks (do NOT hallucinate)

4. Load feature context: Read from FEATURE_DIR:

   • spec.md: Feature requirements and scope
   • plan.md (if exists): Technical details, dependencies
   • tasks.md (if exists): Implementation tasks

   Context Loading Strategy:

   • Load only necessary portions relevant to active focus areas (avoid full-file dumping)
   • Prefer summarizing long sections into concise scenario/requirement bullets
   • Use progressive disclosure: add follow-on retrieval only if gaps detected
   • If source docs are large, generate interim summary items instead of embedding raw text

5. Generate checklist - Create "Unit Tests for Requirements":

   • Create FEATURE_DIR/checklists/ directory if it doesn't exist
   • Generate a unique filename [domain].md using a short, descriptive domain name (e.g., ux.md, api.md, security.md)
   • File handling: If the file does NOT exist, create it and number items from CHK001. If it exists, append new items continuing from the last CHK ID (e.g., last item CHK015 → start at CHK016). Never delete or replace existing checklist content — always preserve and append.

   CORE PRINCIPLE - Test the Requirements, Not the Implementation: Every checklist item MUST evaluate the REQUIREMENTS THEMSELVES for:

   • Completeness: Are all necessary requirements present?
   • Clarity: Are requirements unambiguous and specific?
   • Consistency: Do requirements align with each other?
   • Measurability: Can requirements be objectively verified?
   • Coverage: Are all scenarios/edge cases addressed?

   Category Structure - Group items by requirement quality dimensions:

   • Requirement Completeness (Are all necessary requirements documented?)
   • Requirement Clarity (Are requirements specific and unambiguous?)
   • Requirement Consistency (Do requirements align without conflicts?)
   • Acceptance Criteria Quality (Are success criteria measurable?)
   • Scenario Coverage (Are all flows/cases addressed?)
   • Edge Case Coverage (Are boundary conditions defined?)
   • Non-Functional Requirements (Performance, Security, Accessibility, etc. - are they specified?)
   • Dependencies & Assumptions (Are they documented and validated?)
   • Ambiguities & Conflicts (What needs clarification?)

   HOW TO WRITE CHECKLIST ITEMS - "Unit Tests for English":

   ❌ WRONG (Testing implementation):

   • "Verify landing page displays 3 episode cards"
   • "Test hover states work on desktop"
   • "Confirm logo click navigates home"

   ✅ CORRECT (Testing requirements quality):

   • "Are the exact number and layout of featured episodes specified?" [Completeness]
   • "Is 'prominent display' quantified with specific sizing/positioning?" [Clarity]
   • "Are hover state requirements consistent across all interactive elements?" [Consistency]
   • "Are keyboard navigation requirements defined for all interactive UI?" [Coverage]
   • "Is the fallback behavior specified when logo image fails to load?" [Edge Cases]
   • "Are loading states defined for asynchronous episode data?" [Completeness]
   • "Does the spec define visual hierarchy for competing UI elements?" [Clarity]

   ITEM STRUCTURE — each item should:

   • Use question format asking about requirement quality
   • Focus on what's WRITTEN (or not written) in the spec/plan
   • Include quality dimension in brackets [Completeness/Clarity/Consistency/etc.]
   • Reference spec section [Spec §X.Y] when checking existing requirements
   • Use [Gap] marker when checking for missing requirements

   EXAMPLES BY QUALITY DIMENSION:

   Completeness:

   • "Are error handling requirements defined for all API failure modes? [Gap]"
   • "Are accessibility requirements specified for all interactive elements? [Completeness]"
   • "Are mobile breakpoint requirements defined for responsive layouts? [Gap]"

   Clarity:

   • "Is 'fast loading' quantified with specific timing thresholds? [Clarity, Spec §NFR-2]"
   • "Are 'related episodes' selection criteria explicitly defined? [Clarity, Spec §FR-5]"
   • "Is 'prominent' defined with measurable visual properties? [Ambiguity, Spec §FR-4]"

   Consistency:

   • "Do navigation requirements align across all pages? [Consistency, Spec §FR-10]"
   • "Are card component requirements consistent between landing and detail pages? [Consistency]"

   Coverage:

   • "Are requirements defined for zero-state scenarios (no episodes)? [Coverage, Edge Case]"
   • "Are concurrent user interaction scenarios addressed? [Coverage, Gap]"
   • "Are requirements specified for partial data loading failures? [Coverage, Exception Flow]"

   Measurability:

   • "Are visual hierarchy requirements measurable/testable? [Acceptance Criteria, Spec §FR-1]"
   • "Can 'balanced visual weight' be objectively verified? [Measurability, Spec §FR-2]"

   Scenario Classification & Coverage (Requirements Quality Focus):

   • Check if requirements exist for: Primary, Alternate, Exception/Error, Recovery, Non-Functional scenarios
   • For each scenario class, ask: "Are [scenario type] requirements complete, clear, and consistent?"
   • If scenario class missing: "Are [scenario type] requirements intentionally excluded or missing? [Gap]"
   • Include resilience/rollback when state mutation occurs: "Are rollback requirements defined for migration failures? [Gap]"

   Traceability Requirements:

   • MINIMUM: ≥80% of items MUST include at least one traceability reference — a spec section [Spec §X.Y], or a marker: [Gap], [Ambiguity], [Conflict], [Assumption]
   • If no ID system exists: "Is a requirement & acceptance criteria ID scheme established? [Traceability]"

   Surface & Resolve Issues (Requirements Quality Problems): Ask questions about the requirements themselves:

   • Ambiguities: "Is the term 'fast' quantified with specific metrics? [Ambiguity, Spec §NFR-1]"
   • Conflicts: "Do navigation requirements conflict between §FR-10 and §FR-10a? [Conflict]"
   • Assumptions: "Is the assumption of 'always available podcast API' validated? [Assumption]"
   • Dependencies: "Are external podcast API requirements documented? [Dependency, Gap]"
   • Missing definitions: "Is 'visual hierarchy' defined with measurable criteria? [Gap]"

   Content Consolidation:

   • Soft cap: If raw candidate items > 40, prioritize by risk/impact
   • Merge near-duplicates checking the same requirement aspect
   • If >5 low-impact edge cases, create one item: "Are edge cases X, Y, Z addressed in requirements? [Coverage]"

   🚫 ABSOLUTELY PROHIBITED (these make it an implementation test, not a requirements test):

   • ❌ Any item starting with "Verify", "Test", "Confirm", "Check" + implementation behavior
   • ❌ References to code execution, user actions, system behavior
   • ❌ "Displays correctly", "works properly", "functions as expected"
   • ❌ "Click", "navigate", "render", "load", "execute"
   • ❌ Test cases, test plans, QA procedures
   • ❌ Implementation details (frameworks, APIs, algorithms)

   ✅ REQUIRED PATTERNS (these test requirements quality):

   • ✅ "Are [requirement type] defined/specified/documented for [scenario]?"
   • ✅ "Is [vague term] quantified/clarified with specific criteria?"
   • ✅ "Are requirements consistent between [section A] and [section B]?"
   • ✅ "Can [requirement] be objectively measured/verified?"
   • ✅ "Are [edge cases/scenarios] addressed in requirements?"
   • ✅ "Does the spec define [missing aspect]?"

6. Structure Reference: Generate the checklist following the canonical template in .specify/templates/checklist-template.md for title, meta section, category headings, and ID formatting. If template is unavailable, use: H1 title, purpose/created meta lines, ## category sections containing - [ ] CHK### <requirement item> lines with globally incrementing IDs starting at CHK001.

7. Report: Output the full checklist path, item count, whether the run created or appended, and a summary of: focus areas selected, depth level, actor/timing, and any explicit user-specified must-have items incorporated.

Important: Each /speckit-checklist invocation uses a short, descriptive filename and either creates a new file or appends to an existing one. This allows multiple typed checklists (e.g., ux.md, test.md, security.md) with memorable, purpose-indicating names that are easy to navigate in the checklists/ folder. To avoid clutter, use descriptive types and clean up obsolete checklists when done.

Anti-Examples: What NOT To Do

❌ WRONG - These test implementation, not requirements:

- [ ] CHK001 - Verify landing page displays 3 episode cards [Spec §FR-001]
- [ ] CHK002 - Test hover states work correctly on desktop [Spec §FR-003]
- [ ] CHK003 - Confirm logo click navigates to home page [Spec §FR-010]
- [ ] CHK004 - Check that related episodes section shows 3-5 items [Spec §FR-005]

✅ CORRECT - These test requirements quality:

- [ ] CHK001 - Are the number and layout of featured episodes explicitly specified? [Completeness, Spec §FR-001]
- [ ] CHK002 - Are hover state requirements consistently defined for all interactive elements? [Consistency, Spec §FR-003]
- [ ] CHK003 - Are navigation requirements clear for all clickable brand elements? [Clarity, Spec §FR-010]
- [ ] CHK004 - Is the selection criteria for related episodes documented? [Gap, Spec §FR-005]
- [ ] CHK005 - Are loading state requirements defined for asynchronous episode data? [Gap]
- [ ] CHK006 - Can "visual hierarchy" requirements be objectively measured? [Measurability, Spec §FR-001]

Key Differences:

• Wrong tests if the system works correctly; Correct tests if the requirements are written correctly
• Wrong verifies behavior; Correct validates requirement quality
• Wrong asks "Does it do X?"; Correct asks "Is X clearly specified?"

Post-Execution Checks

Check for extension hooks (after checklist generation):

• Discover hooks across all extension files (multi-file discovery), not just the central file:
  • Read .specify/extensions.yml from the project root (if present) and collect entries under the hooks.after_checklist key.
  • Then enumerate every .specify/extensions/*/*.yml file in sorted order, parse each, and collect its hooks.after_checklist entries too — so a hook registered only in a per-extension file (e.g. the feedback extension at .specify/extensions/feedback/feedback.yml) is still discovered and runs on phase completion.
  • Merge all collected entries and dedupe by (extension, command) (first occurrence wins, so a hook declared in both files runs once).
  • Hook execution precedence (D1): when settings.auto_execute_hooks: true in .specify/extensions.yml, a mandatory hook (optional: false) auto-runs with no confirmation; an optional hook (optional: true) is always surfaced ("To execute: /{command}") and is never force-run by auto_execute_hooks; a hook with a non-empty condition is never evaluated by this skill — evaluation is left to the executor and the notice reports the resolved decision. When auto_execute_hooks: false, even mandatory hooks are surfaced for confirmation.
  • Effective-hooks notice (D2): after the merge + dedup by (extension, command), emit one consolidated notice for the phase so the operator never hand-reconciles files — the promoted feedback hook (optional: false) appears as auto-run, never as a surfaced optional:

    ## Effective hooks for checklist
    - {extension}:{command} — auto-run        (mandatory; auto_execute_hooks=true)
    - {extension}:{command} — surfaced        (optional)
    - {extension}:{command} — skipped         (enabled: false)
    - {extension}:{command} — condition-deferred
    

  • If a file is absent, no hooks are registered, or its YAML cannot be parsed/is invalid, skip that file silently and continue.
• For every optional: true hook that is discovered but not executed this phase, emit one line so the skip is a visible decision: Note: optional hook {extension}:{command} is registered but was not run (skipped).
• Filter out hooks where enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
• Do not 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
• For each executable hook, output the following based on its optional flag:
  • Optional hook (optional: true):

    ## Extension Hooks
    
    **Optional Hook**: {extension}
    Command: `/{command}`
    Description: {description}
    
    Prompt: {prompt}
    To execute: `/{command}`
    

  • Mandatory hook (optional: false):

    ## Extension Hooks
    
    **Automatic Hook**: {extension}
    Executing: `/{command}`
    EXECUTE_COMMAND: {command}
