Inventory-before-rewrite: map every table/endpoint/engine/UI to a destination tag, prove zero regressions, retire only when replacement is live. Use when migrating/reframing an existing product, consolidating AI engines, or the user asks for an inventory audit / lossless migration / “don’t lose anything.” NOT for green-field apps with nothing to preserve.
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
# Lossless migration Chat: [RESPONSE.md](./RESPONSE.md). Full method: [METHODOLOGY.md](./METHODOLOGY.md). ## Operating order ### 1. Migration or skip? (§1) Green-field / toy → skip. Existing users/behaviors → continue. No constitution → hand to `constitution-first` first. ### 2. Wire the trio (§2) Constitution (why) · inventory audit (proof) · roadmap (phases). Confirm conflict rule. ### 3. Enumerate (§4.1) Data · endpoints · engines · UI · primitives · one-offs. Breadth before deep mapping. ### 4. Tag every row (§3–§4.2) One primary destination tag + one-line mapping. Escalate unknowns — no silent skips. ### 5. Verdict + GAP/RETIRE (§4.3–§4.4) Reframe % · consolidate % · GAP list · RETIRE list (supersede + phase). ### 6. Engine collapse if needed (§5) Cluster AI/functions into one registry; old callers thin then die. ### 7. Roadmap + score (§6–§9) Invisible→visible→scrub. Rubric ≥12/16, no 0 on #1–#5. Log EXAMPLES.md same day. ### 8. Hand off Phases → `linear-setup`. Agent writes → `accept-gated-ai`. Multi-platform parity → `behavior-contracts`. ## Out of scope …

How to install
mdr add tjcages/skills/lossless-migration@sha256:f47f7b9e682abeeeThe line at the top of this page pins the label v0.1.0, 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.
