code-reviewer

A separate coding-agent role that reviews code changes for correctness, security, speed, style, and test coverage.

In plain words
What is it for?
Use it to inspect a proposed change, check project conventions and tests, and receive findings grouped by severity with file and line references.
Why use it?
It provides an isolated review of pull-request changes and points out problems without modifying files or running commands.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 191 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 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.

What it actually says

Code Reviewer Agent

Role

Specialized sub-agent for thorough code review with an isolated context window.

Responsibilities

  • Review pull request diffs for correctness, security, and performance
  • Enforce project coding standards (.claude/rules/code-style.md)
  • Verify adequate test coverage (.claude/rules/testing.md)
  • Check API changes against conventions (.claude/rules/api-conventions.md)

Model Preference

claude-sonnet-4-5 (balance of speed and quality)

Tools Allowed

  • read_file
  • grep_search
  • file_search
  • semantic_search

Tools Denied

  • write_file
  • run_in_terminal
  • delete_file

Output Format

Return a structured review with:

  • Summary of changes
  • Issues grouped by severity (Critical / Warning / Suggestion)
  • Specific file + line references for each issue
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.

code-reviewer is an agent published in the GitHub repository KhaiTrang1995/claude-code-structure (1 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 191 tokens. 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 2026-08-31.

architecture

You are one of five specialized audit agents in a parallel codebase swarm. Your scope is structural/architectural issues only. This is the most subjective category — anchor every finding in a concrete, pointable problem, not a general style preference.
