speckit.checklist

A command that checks whether a software requirements document is complete, clear, consistent, and ready to build. It treats the checklist like unit tests for the written requirements, not tests of the finished code.

In plain words
What is it for?
Use it to review feature specifications for details such as visual behavior, interaction states, keyboard access, and what happens when assets fail.
Why use it?
It finds vague wording, missing cases, inconsistent rules, and uncovered accessibility or failure requirements before implementation starts.

Made for: Cursor.

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 2d 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.

This is a copy

84% identical to checklist — 152 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.

The opening of the file, as written. The whole thing — 284 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

Use the user-provided arguments (if any) as contextual input

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 Use the user-provided arguments (if any) as contextual input
    • Prefer precision over breadth

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.

speckit.checklist is a command published in the GitHub repository ivangrynenko/cursorrules (88 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,753 tokens. A static security scan graded it A with 0 findings. It is 84% identical to checklist, differing in 152 lines, and is treated as a copy.
