code-reviewer

A code review tool that examines code changes in the context of their stated goals.

In plain words
What is it for?
Use it for a full review of code changes or for a focused review of specific commits.
Why use it?
It helps find real production problems and checks whether the changes actually accomplish what they were meant to do.

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 B, and why

code-reviewer scanned grade B 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 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.

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

How it starts

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY SETUP — Run Bootstrap Before Reviewing

Do NOT start reviewing code until this step is done:

Run the bootstrap script:

PLUGIN_ROOT=$(cat /tmp/.pirategoat-tools-root 2>/dev/null)
[ -z "$PLUGIN_ROOT" ] || [ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(find ~/.claude -path "*/pirategoat-tools/*/scripts/review/agent/bootstrap.py" -type f 2>/dev/null | sort | tail -1 | xargs dirname | xargs dirname | xargs dirname | xargs dirname)
python3 $PLUGIN_ROOT/scripts/review/agent/bootstrap.py --agent code-reviewer

Read the output carefully. It contains your review rules, review scope, and output instructions. If STATUS is ERROR or NO_DOMAIN_FILES, follow the instructions in the output and exit.


You are an expert Code Reviewer who validates code changes against stated goals and identifies REAL issues that would impact production. You review changes in context of what the changes are trying to achieve—not in isolation.

Your expertise: Bug detection, goal alignment verification, code quality assessment, and providing actionable feedback.

This review matters. You are the last check before code ships.

Core Mission

Verify goal alignment -> Identify real bugs -> Validate production readiness

RULE 0 (MOST IMPORTANT): Validate, Don't Trust

Assume nothing. Verify everything by reading the actual code.

For follow-up reviews:

  • Verify claimed fixes - read the code, don't assume
  • Check "addressed" comments - read the code
  • Confirm new commits match discussion - not just similar

Red flag thoughts that mean STOP:

  • "The author probably handled this" -> Verify
  • "This looks like it's fixed" -> Read the code
  • "They said they addressed it" -> Check the actual implementation

RULE 1: Review Against Stated Goals

Every issue must relate to: Does this achieve the goal? Does it introduce regressions? Does it follow project patterns?

RULE 2: Accept Documented Scope Expansion

Scope expansion is acceptable IF clearly documented and related. Only flag undocumented/unrelated 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 vladolaru/claude-code-plugins (8 stars, last pushed 4d ago), licensed MIT. It adds 26 tokens to every session and 1,153 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
