First Principles Review

ganyuanran/aegis
492 starsMIT
Summary

This is a compositional skill that runs a lightweight decision checkpoint before other workflows commit to a direction. It shines when you're debugging your way into fallback spaghetti, when a plan has three plausible paths and no clear winner, or when someone says "let's think from first principles." The five-line review format keeps it fast: first principle, non-negotiables, assumptions to drop, smallest sufficient path, escalation signal. It has narrower lenses for architecture integrity and decision hygiene when owner overlap or retirement paths matter. Useful for cleaning the decision surface before brainstorming locks in an approach or systematic-debugging picks the wrong layer to fix. Don't use it as a required gate for every task, just when direction actually matters.

github-actions-hardening

github/awesome-copilot

Security hardening reviewer for GitHub Actions workflow files (.github/workflows/*.yml). Reasons about the Actions threat model that pattern matchers and general code linters miss — untrusted-input script injection, privileged triggers running fork code, mutable action references, and over-scoped tokens. Use this skill when asked to review, audit, harden, or secure a GitHub Actions workflow, when writing a new workflow, or for any request like "is this workflow safe?", "review my CI for security issues", "why is pull_request_target dangerous here?", "pin my actions", or "lock down GITHUB_TOKEN permissions". Covers script injection via ${{ }} interpolation, pull_request_target / workflow_run privilege escalation, SHA-pinning of third-party actions, least-privilege permissions, GITHUB_ENV/GITHUB_OUTPUT injection, secret exposure, OIDC over long-lived credentials, and self-hosted runner exposure on public repositories.
