Self Check

Pre-Commit Self-Check

Validate your changes before committing to ensure code quality and security standards are met.

Purpose

This skill performs a comprehensive self-check on staged changes to catch issues before they are committed. It combines code quality checks with security validation.

What It Checks

1. Code Quality

• Syntax errors in changed files
• Linting issues (if linter available)
• Type errors (if type checker available)
• Test coverage for new code

2. Security

• Hardcoded credentials
• Injection vulnerabilities
• Insecure dependencies
• Debug code and TODO comments

3. Git Hygiene

• Commit message format
• No large binary files
• No merge conflict markers
• No unresolved TODOs marked as blockers

Usage

/self-check

Run this skill before git commit to validate your changes.

Process

1. Identify Changes: Get list of staged files
2. Syntax Check: Ensure code parses correctly
3. Security Scan: Check for common vulnerabilities
4. Quality Check: Run available linters
5. Report: Summarize findings with actionable items

Output Format

=== Self-Check Results ===

Staged Files: 5
  - src/handler.py
  - src/utils.py
  - tests/test_handler.py
  - package.json
  - README.md

[PASS] Syntax Check: All files parse correctly
[FAIL] Security Check: 2 issues found
  - src/handler.py:25 - Potential SQL injection
  - src/utils.py:10 - Hardcoded password

[PASS] Quality Check: No linting errors
[WARN] Coverage: New code in handler.py not covered by tests

Recommendation: Fix security issues before committing

Exit Codes

• 0: All checks passed
• 1: Security issues found (blocking)
• 2: Quality issues found (warning)

Integration

This skill should be run:

1. Before every commit
2. As part of the remediation loop
3. When requested by the orchestrator
