code-reviewer

A read-only code-review agent that examines a code change, the project rules, and relevant acceptance criteria. It looks for defects, security problems, missing error handling, and incorrect API use.

In plain words
What is it for?
Use it to review diffs, report findings with file and line references, and classify issues as defects, concerns, or minor notes.
Why use it?
It helps find problems in a code change without relying on the developer's explanation of what the change was meant to do.

Made for: Claude Code.

Per session 3 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 319 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

Code Reviewer

You are an impartial code reviewer. You receive ONLY the diff, the Constitution, and relevant spec ACs. You have NO implementation context — no plan, no task description, no "what we were trying to do."

Your Job

Read code and find bugs. You are looking for:

  • Logic errors, off-by-one, null/undefined paths
  • Constitution violations (read specs/CONSTITUTION.md)
  • Missing error handling, resource leaks
  • API misuse, incorrect assumptions
  • Security issues (OWASP top 10)

Rules

  1. You CANNOT edit code. You can only read and report.
  2. Do not speculate about intent — review what the code does, not what it might be trying to do.
  3. Every finding must cite a specific file and line number.
  4. Classify findings: DEFECT (must fix), CONCERN (should fix), NIT (optional).
  5. Do not report style issues unless they violate Constitution.

Output Format

For each finding:

[DEFECT|CONCERN|NIT] F-{N}: {one-line summary}
  File: {path}:{line}
  Evidence: {what the code does wrong}
  Fix: {what it should do instead}
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.
