migration-review SKILL.md skillA
migration-review from cluster1900/ai-engineering-from-scratch-zh is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Review database migration files when a change adds or modifies paths under migrations/. Use it before merge to collect forward, rollback, locking, and data-safety evidence.
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 Review
Review only the migration files named in `$ARGUMENTS` and the code needed to
verify their compatibility. This Skill does not authorize applying a migration.
1. Run `python3 ${CLAUDE_SKILL_DIR}/scripts/check_scope.py $ARGUMENTS`.
2. Stop if the checker rejects any path outside `migrations/`.
3. Read [references/review-checklist.md](references/review-checklist.md).
4. Inspect each accepted file and its schema assumptions.
5. Report forward behavior, rollback limits, lock risk, data-volume risk,
verification evidence, and unresolved blockers.
Return these headings: `Scope`, `Evidence`, `Risks`, `Rollback`, `Blockers`, and
`Decision`. Use `Decision: blocked` whenever required evidence is missing.
The bundled checker is [scripts/check_scope.py](scripts/check_scope.py). The
`allowed-tools` entry pre-approves only that command for the invocation turn; it
does not remove other tools or replace project permission rules.Read the whole file at its exact version.
How to install
mdr add cluster1900/ai-engineering-from-scratch-zh/migration-review@sha256:5e5e0cb4bcd5f7a0The line at the top of this page pins the label git:20261008.c74aa9d, 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.
