Six-axis Feature Inventory (routes / models / jobs / tests / UI / docs) — a "what we must preserve" spec for greenfield rewrites.
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
Writing: read docs/skills/shared/writing-rule.md before you write a durable artifact. # /extract-features — Feature Inventory for Greenfield Rewrites Walks the target project's codebase across **six discovery axes** and writes a consolidated Feature Inventory. The artefact is the "what we must preserve" specification for a greenfield rewrite (different language, framework, or architecture) — instead of reverse-engineering features one route at a time, hand the inventory to the rewrite team. This skill complements `/handover`: - `/handover` produces a **high-level project assessment** — origin, current health, integration plan, applicable roles. The output is the bridge between "we just inherited this codebase" and "this codebase is now governed by our normal SDLC". - `/extract-features` produces a **granular feature catalogue** — every route, model, job, test name, UI screen, and documented capability the existing system exposes. The output is the input to a greenfield-rewrite spec. Run `/handover` first when adopting an unfamiliar repo; run `/extract-features` second when you've decided to rewrite it. …

How to install
mdr add me2resh/apexyard/extract-features@sha256:42cde68a0fd54366The line at the top of this page pins the label git:20261015.37f5689, 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.
