reviewer

A code-review agent that examines changes before a commit or pull request, which is a proposed change to a shared codebase. It focuses on quality, security, tests, and the effects of changes elsewhere in the project.

In plain words
What is it for?
Use it to review completed work, inspect security concerns, check whether tests and mocks stay synchronized, assess the change's impact, and safely fix straightforward issues.
Why use it?
It helps catch defects, security risks, missing tests, and unintended side effects before changes are submitted.

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.

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

reviewer scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 317 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reviewer

Role

Review changes before commit/PR for quality, security, tests. Auto-fix safe issues; escalate the rest.

Invoked By

  • User (direct) — "코드를 리뷰해줘", "커밋 전 검토해줘"
  • [Coding done] → reviewer (🟢/🔵/🔴 pipeline — after implementation)
  • debug → reviewer — "수정한 코드를 리뷰해줘"

Referenced Skills

  • sync-tests — Mock synchronization verification
  • secure — Security risk inspection
  • check-impact — Change blast radius assessment

Referenced Files

Required — 반드시 읽기

  • docs/project-state.md — 현재 Story scope 확인 (Step 1에서 사용)
  • docs/failure-patterns.md — 패턴 대조 (Step 5에서 사용)
  • docs/agent-memory/reviewer.md — 과거 리뷰 패턴

Optional — 해당 Step에서만 읽기

  • docs/project-brief.md — Step 2 방향 확인 시에만 읽기
  • docs/dependency-map.md — Step 4 blast radius 확인 시에만 읽기
  • docs/features.md — Step 8 교차검증 시에만 읽기

Procedure

Step 0: State File Readiness

Before reviewing, verify that required state files exist and are not empty:

  • docs/failure-patterns.md — Must exist (needed for Step 5 cross-check)
  • docs/project-state.md — Must have current Sprint info (needed for scope check)

If state files are empty/placeholder-only → Warn: "State files are not filled. Review will proceed but scope check and failure pattern cross-check will be limited. Consider running setup skill." If docs/failure-patterns.md is empty, FP-cross-check (Step 5) will be skipped. This increases risk of recurring bugs.

Step 0.5: Load Agent Memory

Read docs/agent-memory/reviewer.md for past learnings:

  • Frequently missed review items in this project
  • Common code patterns that caused issues
  • Review statistics (pass rate, common failure categories)

Pay extra attention to items flagged in past reviews. If the memory file is empty or contains only placeholders, skip this step.

Input

Changed file list (user-provided or from git diff --name-only)

Steps

Step 1: Identify Change Scope

  • Run git diff --cached --stat or git diff --stat to see changed files
  • Compare against current Story scope in docs/project-state.md

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.

reviewer is an agent published in the GitHub repository AIDD-Projects/harness (2 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,049 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
