• Agent Tool Contract Evolution in Production: Preventing Tool Upgrade Failures with Schema Fingerprint, Compatibility Matrix, and Shadow Replay

  Tool upgrades in Agent systems fail not on interface errors but when models keep calling old contracts after parameter and semantic changes. This guide covers Schema fingerprints, compatibility matrices, shadow replay, canary gates, and fast rollback for MCP-based systems.
