Treat AI as a fuzzy wrapper around deterministic code, not a replacement for it. If a task can be solved programmatically—parsing, routing, fetching, transformation—write the code first and only invoke the model where genuine ambiguity exists. This 80/20 split (mostly code, thin AI layer) saves tokens, eliminates hallucinated branches, and dramatically improves consistency. Anthropic itself recommended replacing some MCP calls with TypeScript for the same reason.
