What your agent gets

Every item links to the release note, guide or advisory it came from. Matching runs on your machine: no code leaves it, and there is no telemetry. If nothing upstream matters to your code, your agent hears nothing. Works with npm and PyPI projects.

Replayed on 15 real Next.js, Prisma and NestJS upgrades, the catalog held 92% of the required changes that upstream sources document. Method and results.
