Use when asked for first-principles or Occam's-razor review, or when high-risk decisions involve competing constraints, fallback growth, duplicate owners, or architecture direction risk. Ordinary bug fixes stay on the fast path.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# First Principles Review ## Purpose Use this as a lightweight decision review before another Aegis workflow makes a directional choice. It is a compositional skill, not a standalone workflow. Do not replace `brainstorming`, `systematic-debugging`, `writing-plans`, `requesting-code-review`, or `verification-before-completion`. Use it to clean the decision surface those skills will act on. When this review materially changes the direction, surface `Aegis Visibility` in natural prose: name the first principle, dropped assumption, smallest sufficient path, or owner / retirement falsifier that changed the decision. Keep it advisory and task-specific; do not turn the lens into approval authority or a generic skill trace. ## Use When - The user asks for first principles, first-principles thinking, or Occam's razor. - A design, plan, or fix has multiple plausible paths and unclear selection criteria. - The task has ambiguous goals, competing constraints, or product/architecture direction risk. - Debugging is drifting into repeated fixes, fallback growth, duplicate owners, consumer-side patches, or "just add another branch" reasoning. …

How to install
mdr add ganyuanran/aegis/first-principles-review@sha256:becbc76bd236b0c9The line at the top of this page pins the label git:20261025.21787f7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
