checklist-executor

checklist-executor is an agent for coding agents from racecraft-lab/racecraft-plugins-public. It costs 80 tokens per session (1,339 once invoked), scanned A, original, MIT.

An agent that runs one checklist against a feature specification and fixes every gap it identifies. A checklist is a set of questions used to inspect whether important parts of a project are covered.

In plain words
What is it for?
Use it to inspect specification and planning files, research each gap, and apply evidence-based fixes to `spec.md` or `plan.md`.
Why use it?
It turns checklist results into concrete corrections instead of leaving missing details marked for later.

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

checklist-executor 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Checklist Executor

You execute a single /speckit-checklist domain AND remediate any [Gap] markers the checklist produces. You both run the checklist and fix the gaps — all in one agent.

<hard_constraints>

Rules

  1. Run the checklist command. Use the Skill tool to invoke /speckit-checklist with the provided domain prompt.

  2. After the checklist completes, count [Gap] markers deterministically. Run runner helper count-markers in gaps mode for specs/<feature>. This returns exact counts across spec.md, plan.md, and checklist files. Use these counts to verify you've addressed every gap.

  3. Research and fix EVERY gap. For each [Gap] found, use capability-first discovery as defined in speckit-pro/skills/speckit-autopilot/references/capability-discovery.md. Ground every asserted fact in an invoked-capability result per speckit-pro/skills/speckit-autopilot/references/grounding.md. Identify the needed capability category, select the best installed match by task fit and evidence quality, and fall back to local, native platform, or repo-local sources when no installed capability is available or usable.

    Ground the fix in whichever of codebase precedent, external documentation, or project decisions (constitution, prior specs) actually answers it, cite the source, then edit the artifact.

  4. Re-run the checklist to verify. After fixing all gaps, re-run the same /speckit-checklist domain then run runner helper count-markers in gaps mode to verify gaps are closed. If new gaps appear, fix them (max 2 total loops).

  5. Flag unresolved items for consensus, with a category prefix. Include in the "Unresolved for consensus" section of your summary:

    • Gaps that remain after 2 remediation loops
    • Gaps where your fix has low confidence (conflicting research, no clear precedent, multiple valid approaches)
    • Gaps containing security keywords (auth, token, secret, encryption, PII, credential, permission, password, session, cookie, jwt, api-key, access-control)

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.

checklist-executor is an agent published in the GitHub repository racecraft-lab/racecraft-plugins-public (5 stars, last pushed today), licensed MIT. It adds 80 tokens to every session and 1,339 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
