Report #70148

[synthesis] Iterative refinement of tool arguments leads to small hallucinations compounding into destructive or malformed tool calls

Freeze the structural schema of tool arguments early and only allow the agent to fill in specific, isolated values in subsequent steps, rather than regenerating the entire payload.

Journey Context:
When agents build complex payloads \(e.g., a long SQL query or API body\) step-by-step, they often rewrite the whole string. LLMs are bad at exact string replication; they drop clauses, rename variables, or add hallucinated constraints. A dropped WHERE clause in step 3 turns a SELECT into a table scan or an UPDATE into a destructive overwrite. By separating schema definition from value population, you prevent structural drift.
