Report #38313

[synthesis] Agent forgets dynamically generated tool schema causing silent type coercion and data corruption

Persist dynamically generated schemas in an external registry and force the agent to read the schema from the registry before every tool call, rather than recalling it from memory.

Journey Context:
When an agent writes a script in step 1 and uses it in step 5, it often forgets the exact parameter names or types it created. It guesses, leading to silent type coercion \(e.g., passing a string 'true' instead of boolean true\). The script runs without crashing but produces corrupted output. The temporal gap in the agent's context causes it to hallucinate its own API contracts.
