reviewing-code

reviewing-code is a skill for Claude Code from qte77/claude-code-plugins. It costs 33 tokens per session (610 once invoked), scanned A, original, Apache-2.0.

A focused code-review guide for checking changed files against the task, project rules, security requirements, and coding standards.

In plain words
What is it for?
Use it to review implementation quality, security, compliance, requirements coverage, and validation results.
Why use it?
It keeps reviews proportional to the size of the change and produces specific feedback instead of over-analysis.

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

reviewing-code 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 1mo 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Context

  • Changed files: !git diff --name-only HEAD~1 2>/dev/null || echo "No recent commits"
  • Staged files: !git diff --staged --name-only

Code Review

Scope: $ARGUMENTS

Delivers focused, streamlined code reviews matching stated task requirements exactly. No over-analysis.

Python Standards

See references/python-best-practices.md for comprehensive Python guidelines.

Workflow

  1. Read task requirements to understand expected scope
  2. Check make validate passes before detailed review
  3. Match review depth to task complexity (simple vs complex)
  4. Validate requirements - does implementation match task scope exactly?
  5. Issue focused feedback with specific file paths and line numbers

Review Strategy

Simple Tasks (100-200 lines): Security, compliance, requirements match, basic quality

Complex Tasks (500+ lines): Above plus architecture, performance, comprehensive testing

Always: Use existing project patterns, immediate use after implementation

Review Checklist

Security & Compliance:

  • No security vulnerabilities (injection, XSS, etc.)
  • Follows @AGENTS.md mandatory requirements
  • Passes make validate

Requirements Match:

  • Implements exactly what was requested
  • No over-engineering or scope creep
  • Appropriate complexity level

Code Quality:

  • Follows project patterns in src/
  • Proper type hints and docstrings
  • Tests cover stated functionality

Structural Health:

  • No function exceeds cognitive complexity threshold (suggested default: 15 per function, overridable per-project)
  • No copy-paste duplication across methods (watch for repeated dispatch chains)
  • File aggregate complexity — flag if trending above project norms (suggested default: 50 per file, overridable per-project)

Output Standards

Simple Tasks: CRITICAL issues only, clear approval when requirements met Complex Tasks: CRITICAL/WARNINGS/SUGGESTIONS with specific fixes All reviews: Concise, streamlined, no unnecessary complexity analysis

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.
