Validate every agent output against a typed schema at each handoff to stop cascade failures

Digital Applied·high signal

Context inconsistency — not pattern choice — is the primary reason multi-agent pipelines fail in production: one agent's malformed output silently corrupts every downstream agent. The fix is to validate every inter-agent handoff against a typed schema (Pydantic in Python, Zod in TypeScript) before passing it on, which eliminates the majority of observed cascade failures with a single discipline.
