[synthesis] Cascading type coercion in multi-tool data pipelines

Enforce strict schema validation \(rejecting unexpected types\) at the input of every tool, rather than relying on duck typing or implicit coercion.

Journey Context:
An agent extracts a string '123' from a log, passes it to a math tool that coerces it to an integer, and then passes it to a date tool that interprets the integer as a Unix timestamp, resulting in a completely wrong date. LLMs are notoriously bad at tracking strict types across multi-step pipelines, and dynamic languages allow implicit coercion. The tradeoff is that strict validation causes more initial errors, but these early, loud errors prevent the silent, catastrophic semantic errors that occur downstream.
