code-reviewer

code-reviewer is a skill for Claude Code, Codex from yezannnnn/agentGroup. It costs 65 tokens per session (1,085 once invoked), scanned A, original, MIT.

A code-review toolset for JavaScript, TypeScript, Python, Go, Swift, and Kotlin. It examines changes, source structure, complexity, security risks, and common code-quality problems.

In plain words
What is it for?
Use it to compare branches or review a pull request, detect issues such as exposed secrets, SQL-injection patterns, debug code, and unsafe typing, and generate a review report.
Why use it?
It helps reviewers find risky or hard-to-maintain code before changes are accepted. It also prioritizes files and groups findings by severity.

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 5d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/code_quality_checker.py, scripts/pr_analyzer.py, scripts/review_report_generator.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Code Reviewer

Automated code review tools for analyzing pull requests, detecting code quality issues, and generating review reports.


Table of Contents


Tools

PR Analyzer

Analyzes git diff between branches to assess review complexity and identify risks.

# Analyze current branch against main
python scripts/pr_analyzer.py /path/to/repo

# Compare specific branches
python scripts/pr_analyzer.py . --base main --head feature-branch

# JSON output for integration
python scripts/pr_analyzer.py /path/to/repo --json

What it detects:

  • Hardcoded secrets (passwords, API keys, tokens)
  • SQL injection patterns (string concatenation in queries)
  • Debug statements (debugger, console.log)
  • ESLint rule disabling
  • TypeScript any types
  • TODO/FIXME comments

Output includes:

  • Complexity score (1-10)
  • Risk categorization (critical, high, medium, low)
  • File prioritization for review order
  • Commit message validation

Code Quality Checker

Analyzes source code for structural issues, code smells, and SOLID violations.

# Analyze a directory
python scripts/code_quality_checker.py /path/to/code

# Analyze specific language
python scripts/code_quality_checker.py . --language python

# JSON output
python scripts/code_quality_checker.py /path/to/code --json

What it detects:

  • Long functions (>50 lines)
  • Large files (>500 lines)
  • God classes (>20 methods)
  • Deep nesting (>4 levels)
  • Too many parameters (>5)
  • High cyclomatic complexity
  • Missing error handling
  • Unused imports
  • Magic numbers

Thresholds:

Issue Threshold
Long function >50 lines
Large file >500 lines
God class >20 methods
Too many params >5
Deep nesting >4 levels
High complexity >10 branches

Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
