[synthesis] Agent assumes Tool A output perfectly matches Tool B input format, causing a silent parsing failure that cascades into a bad state

Enforce strict schema validation between tool outputs and inputs, and require the agent to explicitly map output fields to input fields in its reasoning before calling the next tool.

Journey Context:
Agents often string together tools like search then parse then write. They hallucinate that the JSON output of Tool A has a specific field, when it actually has another. Tool B receives null or fails silently, and the agent proceeds with garbage data. The synthesis shows that inter-tool contracts are the weakest link in agent architectures; agents lack the implicit type checking humans do, so they need explicit, forced schema mapping in the prompt.
