speckit-checklist

speckit-checklist is a skill for Claude Code from stefaniuk/loadout. It costs 19 tokens per session (5,072 once invoked), scanned A, a copy of speckit-checklist, MIT.

A workflow tool that creates a development plan from a feature specification. The plan describes how the work should be carried out and includes demonstration steps for checking each phase.

In plain words
What is it for?
Planning features before breaking them into tasks, including documenting decisions, tools, testing expectations, and user-story demonstrations. It is intended for the Speckit workflow mode.
Why use it?
It turns requirements into an implementation approach that developers can follow and verify.

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 6d 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.

Workflow Mode Guard

Use this skill only when the active local workflow mode is speckit.

Before proceeding:

  • Run ./scripts/hooks/workflow-mode.sh status.
  • If the active mode is superpowers, stop and tell the user to switch with make workflow-use mode=speckit or continue with the Superpowers workflow instead.
  • Do not mix speckit-* commands with Superpowers workflow skills in the same session or worktree.

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.

Ownership and checkbox lifecycle:

  • Custom checklists generated by this command are reviewer-owned requirements-quality review artifacts.
  • [x] means the reviewer determined the requirements-quality criterion is satisfied.
  • [x] does NOT mean implementation work is complete.
  • This command generates or appends checklist items; it MUST NOT mark generated items [x].
  • An agent may assist with evaluating items only when explicitly asked by the reviewer.
  • checklists/requirements.md is a separate built-in spec-quality checklist maintained by /speckit-specify and /speckit-clarify; do not treat that exception as applying to custom checklists generated here.

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.
