code-review-assistant

code-review-assistant is a skill for Claude Code, Codex from d-o-hub/github-template-ai-agents. It costs 78 tokens per session (1,747 once invoked), scanned A, original, MIT.

An automated assistant for reviewing code changes, such as a pull request, which is a proposed update to a shared codebase. It examines the changes, summarises them, checks quality, and points out possible problems.

In plain words
What is it for?
Use it to review pull requests, create change summaries, check style and best practices, assess risk, detect code smells, check accompanying tests, and suggest focused refactoring.
Why use it?
It reduces the manual work of inspecting every changed file and helps reviewers notice style issues, security risks, missing tests, and code that may be difficult to maintain.

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-review-assistant 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 4d 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.

Code Review Assistant

Automated code review with intelligent analysis of changes, quality checks, and actionable feedback generation.

When to Use

  • Reviewing pull requests - Analyze diffs and provide feedback
  • Change summarization - Generate PR descriptions from code changes
  • Quality checks - Style guide compliance, best practices
  • Security review - Detect potential security issues in changes
  • Code smell detection - Identify bloaters, dispensables, and couplers
  • Refactoring guidance - Suggest targeted improvements
  • Review automation - Auto-approve simple changes, flag complex ones
  • Learning tool - Explain changes for knowledge sharing

Core Workflow

Phase 1: Change Analysis

  1. Identify modified files - Categorize by type and risk level
  2. Calculate metrics - Lines changed, complexity delta, test coverage
  3. Detect patterns - New features, bug fixes, refactoring, dependencies
  4. Assess risk - Critical paths, public APIs, security-sensitive areas

Phase 2: Quality Assessment

  1. Style compliance - Check against project style guide
  2. Best practices - Design patterns, code organization
  3. Test coverage - Verify tests accompany changes
  4. Documentation - Check for necessary doc updates
  5. Security scan - Identify potential vulnerabilities

Phase 3: Feedback Generation

  1. Summarize changes - High-level description of what changed
  2. Identify issues - Bugs, anti-patterns, performance concerns
  3. Suggest improvements - Refactoring opportunities, optimizations
  4. Highlight positives - Good practices to reinforce
  5. Generate review comments - Specific, actionable feedback

Code Smells Detection

Bloaters

  • Long Method (>30 lines of logic)
  • Large Class (>300 lines)
  • Long Parameter List (>4 params)

Object-Orientation Abusers

  • Switch Statements (replace with polymorphism)
  • Temporary Field
  • Refused Bequest

What ships with it

4 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.
