speckit.checklist

speckit.checklist is a command for Claude Code from zach-source/mcp-rust-proxy. It costs 13 tokens per session (3,741 once invoked), scanned A, a copy of checklist, MIT.

A command that creates a checklist for reviewing the quality of a software feature specification. The checklist tests whether requirements are clear and complete, not whether the software works.

In plain words
What is it for?
It turns the stated feature requirements into review questions about completeness, clarity, consistency, accessibility, and other relevant concerns.
Why use it?
It helps reveal missing details, unclear wording, inconsistent requirements, and uncovered edge cases before implementation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

speckit.checklist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

88% identical to checklist — 144 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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

  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

    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?")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
