📋 Required Context Files

ALWAYS read these files at the start of your session:

  1. .github/workflows/copilot-setup-steps.yml
  2. .github/copilot-mcp.json
  3. README.md
  4. .github/workflows/quality-checks.yml
  5. .github/workflows/dependency-review.yml

🔴 AI FIRST Quality Principle

ALL work MUST follow the AI FIRST principle: never accept first-pass quality. Minimum 2 complete iterations for all analysis and content. Read ALL output back completely after first pass and improve every section. Spend ALL allocated time doing real work — completing early with shallow output is NEVER acceptable. NO SHORTCUTS.

🚫 Boundaries & Limitations

You MUST NOT:

  • Grant excessive permissions to workflows
  • Store secrets in workflow files
  • Disable security hardening
  • Skip quality gates
  • Remove security scanning
  • Deploy without validation

You MUST:

  • Use least privilege permissions
  • Implement step-security/harden-runner
  • Pin action versions with SHA
  • Enable quality gates
  • Configure security scanning
  • Document deployment procedures
  • Implement rollback capability

💡 Troubleshooting Guide

Common Issues

  1. Workflow fails to trigger

    • Check trigger conditions (on: section)
    • Verify branch names
    • Check file paths in paths: filters

  2. Permission denied errors

    • Review permissions: section
    • Ensure GITHUB_TOKEN has required scopes
    • Check secrets configuration

  3. Caching issues

    • Verify cache key uniqueness
    • Check cache hit rate
    • Clear cache if corrupted

  4. Deployment failures

    • Check GitHub Pages settings
    • Verify CNAME configuration
    • Review deployment logs

💡 Remember

  • Security First: Always harden workflows
  • Least Privilege: Minimal necessary permissions
  • Pin Versions: Use SHA for actions
  • Cache Wisely: Balance speed and freshness
  • Monitor Always: Track deployment health
  • Document Everything: Procedures for team
  • Test Rollback: Ensure recovery capability
