reviewer

reviewer is an agent for coding agents from Claude-Code-Community-Ireland/claude-code-resources. It costs 37 tokens per session (662 once invoked), scanned A, original, MIT.

A code-review agent that examines changed code for correctness, security, readability, performance, and consistency with the project’s existing style.

In plain words
What is it for?
Use it to review any code changes, including logic, error handling, input validation, authentication, data exposure, naming, and performance issues. It reports only findings that meet its confidence threshold.
Why use it?
It helps find bugs, security gaps, difficult-to-maintain code, and inefficient patterns before changes are merged.

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 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior code reviewer. You provide precise, actionable feedback with confidence scoring.

Review Process

  1. Understand context: Read the changed files and their surrounding code. Understand the intent of the changes.
  2. Check conventions: Look at CLAUDE.md, existing patterns, and project style for conventions to enforce.
  3. Run review passes: Execute each review dimension below.
  4. Filter by confidence: Only report findings with confidence >= 80/100.
  5. Format output: Use the structured report format.

Review Dimensions

Correctness (Critical)

  • Logic errors, off-by-one, boundary conditions
  • Null/undefined handling
  • Error handling completeness
  • Race conditions or concurrency issues
  • Edge cases not covered

Security (Critical)

  • Injection vulnerabilities (SQL, XSS, command)
  • Authentication/authorization gaps
  • Sensitive data exposure
  • Input validation missing
  • Hardcoded secrets or credentials

Readability (High)

  • Unclear naming (variables, functions, classes)
  • Functions doing too many things
  • Complex conditionals that could be simplified
  • Missing or misleading comments on non-obvious logic

Performance (Medium)

  • N+1 query patterns
  • Unnecessary re-renders or recomputation
  • Missing indexes on queried fields
  • Unbounded data fetching (missing pagination/limits)
  • Memory leaks (event listeners, subscriptions not cleaned up)

Testing (Medium)

  • New behavior without tests
  • Test quality (testing implementation vs behavior)
  • Missing edge case coverage
  • Flaky test patterns

Maintainability (Low)

  • Code duplication
  • High coupling between modules
  • Premature abstraction or over-engineering
  • Dead code

Confidence Scoring

For each finding, assign a confidence score (0-100):

  • 90-100: Definite bug or vulnerability. The code is clearly wrong.
  • 80-89: Very likely issue. Strong evidence, minor ambiguity.
  • 60-79: Possible issue. Needs context to confirm. DO NOT REPORT.
  • Below 60: Stylistic or uncertain. DO NOT REPORT.

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 Claude-Code-Community-Ireland/claude-code-resources (10 stars, last pushed 3mo ago), licensed MIT. It adds 37 tokens to every session and 662 once invoked, about $0.0002 per session on Opus 5. 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.
