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.
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)
Metaphor: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.
User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Pre-Execution Checks
Check for extension hooks (before checklist generation):
- Check if
.specify/extensions.yml exists in the project root.
- If it exists, read it and look for entries under the
hooks.before_checklist key
- If the YAML cannot be parsed or is invalid, skip hook checking silently and 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 Execution Steps.
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
Execution Steps
-
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").
-
IF EXISTS: Load .specify/memory/constitution.md for project principles and governance constraints.
-
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
Generation algorithm:
- 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").
- Cluster signals into candidate focus areas (max 4) ranked by relevance.
- Identify probable audience & timing (author, reviewer, QA, release) if not explicit.
- Detect missing dimensions: scope breadth, depth/rigor, risk emphasis, exclusion boundaries, measurable acceptance criteria.
- 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
- Never ask the user to restate what they already said
- Avoid speculative categories (no hallucination). If uncertain, ask explicitly: "Confirm whether X belongs in scope."
Important: Each /speckit-checklist command invocation uses a short, descriptive checklist filename and either creates a new file or appends to an existing one. This allows:
- Multiple checklists of different types (e.g.,
ux.md, test.md, security.md)
- Simple, memorable filenames that indicate checklist purpose
- Easy identification and navigation in the
checklists/ folder
To avoid clutter, use descriptive types and clean up obsolete checklists when done.

- "Are visual hierarchy requirements defined with measurable criteria? [Clarity, Spec §FR-1]"
- "Is the number and positioning of UI elements explicitly specified? [Completeness, Spec §FR-1]"

- "Are accessibility requirements specified for all interactive elements? [Coverage, Gap]"
- "Is fallback behavior defined when images fail to load? [Edge Case, Gap]"
- "Can 'prominent display' be objectively measured? [Measurability, Spec §FR-4]"
API Requirements Quality: api.md
Sample items:
- "Are error response formats specified for all failure scenarios? [Completeness]"
- "Are rate limiting requirements quantified with specific thresholds? [Clarity]"
- "Are authentication requirements consistent across all endpoints? [Consistency]"
- "Are retry/timeout requirements defined for external dependencies? [Coverage, Gap]"

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: Verification of behavior
- Correct: Validation of requirement quality
- Wrong: "Does it do X?"
- Correct: "Is X clearly specified?"
