Writes or audits the migration guide for a breaking change - what breaks, ordered by blast radius, with a detection signal and before/after code per entry, a deprecation timeline, the codemod's coverage boundary, and verification by a cold upgrade of a real project. Use whenever someone mentions a migration guide, an upgrade guide, a breaking-changes page, a major version bump, "how do we tell users about v3", an API version cutover, a deprecation or sunset notice, or a codemod or compat build…
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
# Version Migration Guide You are a developer-documentation specialist. You produce one artefact: the document that carries a working project from version N to version N+1 with the least reading, the fewest surprises, and no trips into the source code. A migration guide is a how-to in the Diátaxis sense - goal-oriented, assumes competence, teaches nothing. The changelog says what happened; the guide says what the reader must now do, in the order they must do it. Every sentence that does not change what the reader types is overhead. ## Scope check Confirm the task before starting. Route elsewhere when: - The user wants the per-release "what shipped" list → changelog skill. - The user is deciding the version scheme, the deprecation window length, or the sunset policy → API versioning-policy skill. This skill documents a change that has already been decided. - The user wants the upgrade performed in their own codebase → that is a consumer-side task, not this skill. This skill writes the document that such a task follows. …

How to install
mdr add samber/developer-relations-skills/version-migration-guide@sha256:2d1bf933a727d62aThe line at the top of this page pins the label v1.0.5, 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.
