Migrate a known, enumerated set of targets one at a time until EVERY one is done — one iteration picks the next un-migrated target from a checklist, transforms it, verifies behaviour-identical (the suite stays green), commits a checkpoint, and marks it migrated, with a hard exit that BOTH the suite is green AND a grep for the old pattern returns zero. The only loop over a fixed target set whose proof is "no legacy pattern remains," not just "tests pass." Use for a codemod across a repo, a…
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
# migration-loop > **A configuration of [`loop-controller`].** That skill supplies the loop > machinery — primitive selection, the full guardrail stack, state > externalization. This skill supplies the two things specific to "migrate a > fixed set of targets to completion": a **default-FAIL target checklist** driven > one entry per iteration, and a **proof that no legacy pattern remains** (a grep > for the old pattern returning zero), not merely "tests pass." Read > `loop-controller` for the guardrails; they're inherited, not repeated here. > > **Why `disable-model-invocation`:** this loop edits and commits code on its own > — a checkpoint commit per migrated target — until the whole set is done. You > want to *type* `/migration-loop` (or have the orchestrator dispatch it) — not > have Claude silently start rewriting every file because it noticed an old API. ## The 5-part contract | Part | This loop | |---|---| …

How to install
mdr add ivy00johns/skill-madness/migration-loop@sha256:d773cbf5992b85a0The line at the top of this page pins the label v1.1.0, 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.
