Speckit Checklist Agent Skill

Speckit Checklist Skill

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).

Execution Steps

• Setup: Run .specify/scripts/powershell/check-prerequisites.ps1 -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").

• 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."

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.

• 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)

• 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

• Generate checklist - Create "Unit Tests for Requirements":
• Create FEATURE_DIR/checklists/ directory if it doesn't exist
• Generate unique checklist filename:
• Use short, descriptive name based on domain (e.g., ux.md, api.md, security.md)
• Format: [domain].md
• If file exists, append to existing file
• Number items sequentially starting from CHK001
• Each /speckit.checklist run creates a NEW file (never overwrites existing checklists)

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 follow this pattern:

• 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
• Each item should reference: spec section [Spec §X.Y], or use markers: [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]?"

• 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.

• Report: Output full path to created checklist, item count, and remind user that each run creates a new file. Summarize:
• Focus areas selected
• Depth level
• Actor/timing
• Any explicit user-specified must-have items incorporated

Important: Each /speckit.checklist command invocation creates a checklist file using short, descriptive names unless file already exists. 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.

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?"
