Report #36330

[agent\_craft] Tool arguments contain reasoning text like 'Let me calculate...' instead of pure data

Separate reasoning and tool-calling into distinct phases using explicit XML delimiters \(e.g., ... vs ...\); validate that arguments match JSON schema before execution and strip any natural language.

Journey Context:
ReAct pattern encourages reasoning \+ action in one block, but this bleeds explanatory text into tool arguments, causing parse failures. Better: Internal monologue \(chain-of-thought\) should be in a separate field or wrapped in tags that are stripped before tool execution. This prevents 'thought' contamination of function parameters. Tradeoff: extra tokens for separation, but eliminates argument parsing errors from reasoning residue.
