What’s Changed

MigraDiff v1.4.0 turns the PostgreSQL schema-diff tool into a complete AI-powered migration assistant. Four schema-aware AI flags, all optional — the core diff engine stays dependency-free.

Added

  • --explain — plain-English explanation of any migration
  • --rollback — generates a reversal migration for a given diff
  • --advise — deterministic + AI risk assessment of a migration
  • --generate — writes a migration from a plain-English description, using your real table names and column types from a live connection or schema file

Safety

  • --generate hard-refuses bulk-destructive requests (“drop all”, “wipe”, etc.) before any API call is made
  • Soft-warns and flags individual destructive operations
  • All AI output is marked as AI-generated; temperature 0 for determinism
  • --generate is combinable with --advise for immediate risk feedback

175 tests passing. AI features require an Anthropic API key:
