tmb_audit

tmb_audit is a skill for Claude Code from trustmybot/plugin. It costs 63 tokens per session (368 once invoked), scanned A, original, MIT.

A procedure for auditing software components or architectures by checking their outputs against stated rules and live data. It starts with required output shape and boundaries, then records evidence for each pass or violation.

In plain words
What is it for?
Use it to inspect scrapers, data-producing components, or system designs; define invariants, test them against live data, and report architecture-level failures with evidence.
Why use it?
It discourages accepting an architecture as correct based only on reading its code. Live queries, samples, counts, and reproducible commands make findings easier to 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

tmb_audit 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 15d 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

Audit

When the Human asks you to audit, verify, check or review an architecture, assume the design is flawed until live data shows otherwise. Start from what the component produces, then work back to the code.

  1. Name the component and its invariants. Say which component you are auditing and list what its outputs must satisfy: their shape, the fields that must be present (null floors), the closed sets their enums draw from, and the boundaries they must respect — for a scraper, "the job post alone, with the sidebar left out".
  2. Test each invariant against live data first. Query the rows, take samples, count the violations, or run a dry run — before you read the code. Record every result with the query or command that produced it, so the Human can re-run it.
  3. Report architecture-first. Lead with the design flaw a violation exposes, then the violation itself, each with its evidence: the rows, the samples, the counts.
  4. Prove a clean result too. "Nothing is wrong" is a claim like any other; back it with the same queries, samples and counts that would have caught a violation.
  5. Keep every finding checked. Each failed invariant becomes a verification[] assertion in the fix task's spec, so the invariant stays tested after the fix lands.

Read the code once the evidence points somewhere: it explains a violation you have already measured.

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_audit is a skill published in the GitHub repository trustmybot/plugin (6 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 368 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-13.
