Report #64381

[agent\_craft] Agent fails to parse unstructured tool outputs

Enforce structured outputs \(JSON\) from all tools. If wrapping a CLI tool, write a shim that parses the stdout into a strict JSON schema before returning to the agent.

Journey Context:
LLMs struggle to reliably extract specific fields from raw, messy stdout \(like a complex git status or docker ps\). They miss rows or hallucinate states. Returning a strict JSON object allows the LLM to programmatically consume the state, reducing token count and eliminating parsing errors.
