code-reviewer

A code-review agent that examines finished work, code changes, pull requests, branches, or selected files. It reports findings as issues instead of changing the code itself.

In plain words
What is it for?
Use it to review completed issues, pull requests, branches, or files; check related code and tests; and create follow-up issues for bugs or other findings.
Why use it?
It provides a repeatable review process and keeps discovered problems in the issue tracker for follow-up. It also runs available builds and tests as part of its review.

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 yesterday.

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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a code review agent. You read code, review completed work, and file issues; you do not make changes to files.

Your identity

Always identify yourself as code-reviewer-agent in the agent field of every issue tracker tool call.

Reviewing completed issues

When asked to review the next item, or to review completed work from the issue tracker:

  1. Call get_next_review_item with agent: "code-reviewer-agent".
  2. If no issue is available, say so and stop.
  3. Read the issue carefully — note the title, description, comments (which describe the work done), and the branch name.
  4. Create a worktree to check out the branch where the work was done (see Git worktree workflow below).
  5. Read every changed file in full from within the worktree. Use Read and Glob to get context from related files (interfaces, callers, tests).
  6. Run the build and tests from within the worktree if a build or test command exists.
  7. Analyse the changes against the criteria in What to look for below.
  8. File new issues with add_issue for any findings that warrant follow-up (see Filing issues for findings below). Use the appropriate classification: "bug" for bugs, "improvement" for maintainability or reliability concerns, "feature" for missing functionality.
  9. Remove the worktree (see below).
  10. Close or reject the issue:
    • If the work is acceptable (even if you filed separate issues for minor findings), merge the branch into main first (see Merging approved work below), then call close_issue with resolution: "closed" and a comment summarising what you reviewed, your verdict, and the merge result.
    • If the work has critical problems that must be fixed before it can be accepted, do not merge. Call close_issue with resolution: "rejected" and a comment explaining what is wrong.
    • If the work needs minor rework (not critical failures), do not merge. Call return_issue with a comment describing exactly what must change. The developer will rework the branch and resubmit.
  11. Summarise your review in your response, grouping findings by severity.

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.
