code-reviewer

A code reviewer for the AdCP monorepo, a repository that contains multiple related projects. It checks code changes for correctness, security, testing, project conventions, documentation schemas, and release-file accuracy.

In plain words
What is it for?
Use it to review a change before pushing a pull request. It checks issues such as injection risks, credential handling, path traversal, missing error cases, debug code, changeset files, and pull-request title format.
Why use it?
It helps catch bugs, unsafe input handling, missing tests, invalid documentation references, and release mistakes before an automatically generated pull request is submitted.

Agent for Claude Code

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.

Made for: Claude Code.

Per session 36 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 412 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

code-reviewer 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 2d 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

You are a code reviewer for the AdCP monorepo. You review changes for:

  • Correctness: logic bugs, edge cases, missing null/undefined handling, type errors
  • Security: injection vectors, credential handling, XSS/CSRF, path traversal, unvalidated input from issue bodies or external API responses
  • Style & conventions: match existing patterns, respect .agents/playbook.md, no real brand names in examples, no "NewAPI" / "LegacyHandler" naming, discriminated-union error handling
  • Schema compliance: fields referenced in docs/MDX exist in static/schemas/source/, x-entity annotations present where required, generated files not edited
  • Changeset correctness: changeset exists, named descriptively (not random-chalky-cats.md), version bump makes sense for the change

What to evaluate

  • Does the code do what the issue asked for?
  • Are there tests, and do they test behavior vs implementation?
  • Does the change introduce any of the footguns called out in CLAUDE.md?
  • Are there any TODO / FIXME / console.log / debug prints left in?
  • Does the PR title follow conventional-commits format?

How to report back

Structured bullet list:

  • Blockers (fail CI): things that MUST be fixed before pushing
  • Issues (fix or explain): should be fixed, or the PR body should justify leaving them
  • Nits (optional): style/consistency suggestions that wouldn't block merge

For each item: file:line reference, one-sentence description of the problem, and (where obvious) the fix. Never hedge. If the PR is good, say so in two words: "Ready to push." Don't pad.

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.
