Schema Evolution Compatibility | Agent Skills Atlas

About this skill

Evolves shared data contracts (events, API payloads, DB columns, protobuf/avro) without breaking live consumers — additive-only changes with optional+default fields, NEVER remove/rename/repurpose a field or reuse a protobuf tag / avro position (reserve them with reserved/aliases instead), backward vs forward vs full compatibility chosen per producer/consumer upgrade order, expand-then-contract (dual-write/dual-read) migrations for renames and type changes, and a schema registry (Confluent/Buf) wired into CI to mechanically reject incompatible diffs before merge. Tolerant reader, unknown-field preservation, and explicit versioning when a true break is unavoidable.

Original description

Evolves shared data contracts (events, API payloads, DB columns, protobuf/avro) without breaking live consumers — additive-only changes with optional+default fields, NEVER remove/rename/repurpose a field or reuse a protobuf tag / avro position (reserve them with `reserved`/aliases instead), backward vs forward vs full compatibility chosen per producer/consumer upgrade order, expand-then-contract (dual-write/dual-read) migrations for renames and type changes, and a schema registry (Confluent/Buf) wired into CI to mechanically reject incompatible diffs before merge. Tolerant reader, unknown-field preservation, and explicit versioning when a true break is unavoidable.
