# Code Review Helper A comprehensive code review assistant that generates review checklists tailored to the file types in your pull request, with built-in checks for security, performance, style, and testing best practices. ## Overview Code Review Helper automates the tedious parts of code review by scanning changed files and producing: - **File-type-specific checklists** (JavaScript, Python, Go, Rust, SQL, etc.) - **Security audit items** (injection, auth, secrets, input validation) - **Performance review points** (N+1 queries, memory leaks, complexity) - **Style consistency checks** (naming, formatting, import ordering) - **Test coverage reminders** (missing tests, edge cases, mocks) - **PR review templates** ready to paste into GitHub, GitLab, or Bitbucket This skill helps reviewers be thorough and consistent, reducing the chance of overlooked issues reaching production. ## Installation ### Via ClawHub ```bash openclaw install code-review-helper ``` ### Manual Installation 1. Copy the skill to your OpenClaw skills directory: ```bash mkdir -p ~/.openclaw/skills/ cp -r code-review-helper/ ~/.openclaw/skills/ ``` 2. Make the script executable: ```bash chmod +x ~/.openclaw/skills/code-review-helper/scripts/review.sh ``` 3. Verify the installation: ```bash openclaw list --installed ``` ## Requirements - **git** (version 2.0 or higher) - **bash** (version 4.0 or higher) - Standard Unix utilities: **awk**, **grep**, **sed**, **sort**, **wc** Compatible with Linux, macOS, and Windows (via Git Bash, WSL, or MSYS2). ## Usage ### Basic Usage Run inside a git repository with staged or committed changes: ```bash openclaw run code-review-helper ``` By default, this analyzes the diff between your current branch and `main`. ### Command-Line Options ```bash openclaw run code-review-helper [OPTIONS] Options: --base <branch> Base branch for comparison (default: main) --head <branch> Head branch/ref to review (default: HEAD) --pr <number> Pull request number (fetches diff from remote) --files <pattern> Glob pattern to filter files (e.g., "src/**/*.py") --security Run security checks only --performance Run performance checks only --style Run style checks only --tests Run test coverage checks only --all Run all check categories (default) --severity <level> Minimum severity: critical, warning, info (default: info) --output <format> Output format: markdown, json, text (default: markdown) --output-file <path> Write checklist to a file instead of stdout --template Generate a blank PR review template --template-style <s> Template style: minimal, standard, thorough (default: standard) ``` ### Direct Script Execution ```bash ./scripts/review.sh --base develop --head feature/auth-refactor ``` ## Configuration ### skill.json Settings ```json { "config": { "check_security": true, "check_performance": true, "check_style": true, "check_tests": true, "severity_levels": ["critical", "warning", "info"], "output_format": "markdown" } } ``` | Setting | Type | Default | Description | |----------------------|---------|------------|-----------------------------------------| | `check_security` | boolean | true | Enable security-related checks | | `check_performance` | boolean | true | Enable performance-related checks | | `check_style` | boolean | true | Enable style and formatting checks | | `check_tests` | boolean | true | Enable test coverage checks | | `severity_levels` | array | all three | Which severity levels to include | | `output_format` | string | "markdown" | Default output format | ### Environment Variables ```bash export CRH_BASE_BRANCH=develop export CRH_SEVERITY=warning export CRH_OUTPUT=json export CRH_CHECKS=security,performance ``` ## Check Categories ### Security Checks The security module scans for common vulnerabilities and risky patterns: | Check | Languages | Severity | |---------------------------|------------------|----------| | Hardcoded secrets/tokens | All | Critical | | SQL injection patterns | Python, JS, Go | Critical | | Command injection | Python, JS, Bash | Critical | | Insecure deserialization | Python, Java | Critical | | Missing input validation | All | Warning | | Unsafe regex patterns | All | Warning | | HTTP instead of HTTPS | All | Warning | | Disabled security headers | JS, Python | Warning | | Eval/exec usage | Python, JS | Warning | | Weak cryptography | All | Warning | | Missing CSRF protection | Python, JS | Info | | Verbose error messages | All | Info | ### Performance Checks The performance module identifies potential bottlenecks: | Check | Languages | Severity | |------------------------------|----------------|----------| | N+1 query patterns | Python, JS | Critical | | Missing database indexes | SQL | Warning | | Unbounded list operations | All | Warning | | Synchronous I/O in async | Python, JS | Warning | | Large object in memory | All | Warning | | Missing pagination | Python, JS, Go | Warning | | Redundant re-computation | All | Info | | Unoptimized imports | Python, JS | Info | | String concatenation in loop | Python, Go | Info | ### Style Checks The style module enforces consistency: | Check | Languages | Severity | |---------------------------|-----------|----------| | Inconsistent naming | All | Warning | | Mixed tabs and spaces | All | Warning | | Import ordering | Python, JS| Info | | Line length violations | All | Info | | Missing docstrings | Python | Info | | Dead code / unused vars | All | Info | | TODO/FIXME/HACK comments | All | Info | | Magic numbers | All | Info | ### Test Checks The test module verifies adequate coverage: | Check | Languages | Severity | |------------------------------|------------|----------| | No tests for new functions | All | Warning | | Missing edge case tests | All | Warning | | Mocking external services | All | Info | | Assert count per test | All | Info | | Test naming conventions | All | Info | | Integration test present | All | Info | ## PR Review Templates Generate a ready-to-use review template: ```bash openclaw run code-review-helper --template --template-style thorough ``` ### Template Styles **Minimal** -- Quick reviews for small changes: ```markdown ## Review - [ ] Changes look correct - [ ] No obvious security issues - [ ] Tests pass ``` **Standard** -- Balanced review for typical PRs: ```markdown ## Review Summary **Reviewer**: ___ **Date**: ___ ### Correctness - [ ] Logic is correct and handles edge cases - [ ] Error handling is appropriate ### Security - [ ] No hardcoded secrets - [ ] Input is validated and sanitized ### Performance - [ ] No obvious performance regressions - [ ] Database queries are optimized ### Tests - [ ] New code has test coverage - [ ] Existing tests still pass ### Notes _Additional comments here_ ``` **Thorough** -- Deep review for critical changes (includes all sections from the Standard template plus architecture, documentation, deployment, and rollback considerations). ## Examples ### Review changes between branches ```bash openclaw run code-review-helper --base main --head feature/payments ``` ### Security-only review ```bash openclaw run code-review-helper --security --severity critical ``` ### Review specific files ```bash openclaw run code-review-helper --files "src/auth/**/*.py" ``` ### Generate JSON report for automation ```bash openclaw run code-review-helper --output json --output-file review.json ``` ### Review a specific PR by number ```bash openclaw run code-review-helper --pr 142 ``` ### Generate a thorough review template ```bash openclaw run code-review-helper --template --template-style thorough ``` ## Integration with CI/CD Add automated review checks to your pipeline: ```yaml - name: Code Review Checks run: | openclaw run code-review-helper \ --base ${{ github.event.pull_request.base.ref }} \ --head ${{ github.event.pull_request.head.sha }} \ --severity warning \ --output json \ --output-file review-results.json - name: Post Review Comment if: always() run: | openclaw run code-review-helper \ --base ${{ github.event.pull_request.base.ref }} \ --output markdown \ --output-file review-comment.md gh pr comment ${{ github.event.pull_request.number }} \ --body-file review-comment.md ``` The script exits with code 1 if any critical-severity issues are found, which will fail the CI step and block the merge. ## Language Support | Language | Security | Performance | Style | Tests | |------------|----------|-------------|-------|-------| | Python | Full | Full | Full | Full | | JavaScript | Full | Full | Full | Full | | TypeScript | Full | Full | Full | Full | | Go | Full | Partial | Full | Full | | Rust | Partial | Partial | Full | Full | | Java | Partial | Partial | Full | Full | | SQL | Full | Full | N/A | N/A | | Bash/Shell | Partial | N/A | Full | N/A | | Ruby | Partial | Partial | Full | Full | ## Troubleshooting ### "No changes found" message Ensure there are actual differences between the base and head branches: ```bash git diff main...HEAD --stat ``` ### Script takes too long For large diffs (1000+ files), filter to specific directories: ```bash openclaw run code-review-helper --files "src/**" ``` ### False positives in security checks Some patterns may trigger false positives. You can suppress specific checks by adding a `.crh-ignore` file to your repository root: ``` # .crh-ignore # Ignore specific check IDs SEC-001 # Hardcoded secrets (we use test fixtures) PERF-003 # Unbounded list (known safe in this context) ``` ## License MIT License.
