tmb_swe-checklist

A self-review checklist for a software engineer before marking a coding task complete.

In plain words
What is it for?
Use it to compare the final diff with the specification, confirm every requested file and criterion is covered, and report verification results.
Why use it?
It catches missing requirements, out-of-scope edits, and absent verification that automated checks may not notice.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

tmb_swe-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.

What it actually says

SWE Self-Review

Before task_update_status(completed), confirm these by reading the diff. Mechanical patterns (bare except, mutable defaults, etc.) are caught by scripts/hooks/code-quality-lint.sh on every Edit/Write. You check the things only a human reader would see.

  • Spec fidelity. Every path in the typed files[], every bullet under ## Success Criteria, and every error/edge case named in ## Description has a concrete change in the diff. Quote the item, point to the diff line.
  • Scope discipline. Nothing changed outside the typed files[] except trivial imports. No "while I was there" cleanups. No new TODOs.
  • Verification output. Paste the verification output in your close report.

Escalate (not guess) when:

  • The spec contradicts itself — quote the contradiction.
  • A required fact is missing from the spec — quote what's missing.
  • 3 attempts at the same approach failed — show what you tried.
Changes

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.

tmb_swe-checklist is a skill published in the GitHub repository trustmybot/plugin (6 stars, last pushed 3d ago), licensed MIT. It adds 60 tokens to every session and 278 once invoked, about $0.0003 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.
