Use when changing how a v3 public API maps to v4, editing migration annotations, or regenerating migration/v3-to-v4.md.
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
Update guidance when a v3 public module or API is renamed, moved, removed, replaced, or gains a materially different v4 contract. A v4-only API without a v3 counterpart does not automatically need an annotation. 1. Account for every affected v3 symbol. 2. Read [annotations.md](annotations.md) before adding or changing annotation YAML. Verify every suggested replacement against implementation and tests. 3. When checking or regenerating the reference, or when the API change exists in a committed ref, read [generation.md](generation.md). Otherwise report that generation is deferred. 4. When output was generated, inspect it for unrelated movement and stale refs. The task is complete when every affected v3 symbol is accounted for, annotation replacements are verified, checks and generation succeed when the change is in a committed ref, and every generated difference is explained. Report deferred checks explicitly for uncommitted API changes.

How to install
mdr add scriptedalchemy/agent-bundle/migration-guidance@sha256:90976b6b5b39271dThe line at the top of this page pins the label git:20260901.b4afb74, 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.
