Safe migration

Name: deprecation-and-migration
Author: Hello-Lain

MIT-derived workflow from addyosmani/agent-skills. Keep this entrypoint lean; preserve upstream detail in references/upstream.md.

Use

Read references/upstream.md for staged migration plans, comms, and rollback templates.

Core Rules

Inventory consumers and compatibility constraints.
Use expand/contract, feature flags, dual-write/read, or adapters when risk warrants.
Classify docs before changing them: authoritative, working, historical, stale, duplicate, temporary, or redundant.
Merge unique decisions, verification, and user-facing guidance into the authoritative location before deleting duplicate, temporary, or agent-generated docs.
Verify references and active consumers before archiving or deleting documentation.
Define completion metrics, rollback, and cleanup criteria.

Validation

Run relevant repo tests/lint/build or targeted runtime checks.
If verification cannot run, state why and give the strongest evidence collected.
