audit

audit is a skill for Claude Code from rvdbreemen/adr-kit. It costs 26 tokens per session (269 once invoked), scanned A, original, MIT.

A read-only checker that reviews both Architecture Decision Records (ADRs) and code for rule violations.

In plain words
What is it for?
Use it to audit the whole codebase or a code diff, checking whether code follows accepted ADRs and whether the ADRs pass their own checks.
Why use it?
It separates problems in the code from problems in the decision documents, so each can be addressed by the right owner.

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

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 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.

What it actually says

Audit ADRs and code

Invoke explicitly with $adr-kit:audit when needed. Resolve <plugin-root> from this installed skill. Use only bundled, local ADR Kit tools and follow this canonical workflow:

  1. Run python <plugin-root>/bin/adr-audit --whole-codebase --adr-dir docs/adr --repo-root ., or --diff - with a piped unified diff for the hook and pull-request case.
  2. Read the exit code before the output: 0 clean, 1 the code violates an Accepted ADR, 3 the ADR set fails its own gates, 4 both, 2 the audit could not run.
  3. Report the two failures separately and name their owners; never collapse a code violation and an ADR-quality failure into one verdict, and never present exit 2 as a pass.
  4. Add --llm only with explicit user confirmation, because it spends money per opted-in ADR.

Do not contact another model or mutate user-owned instructions.

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.
