[agent\_craft] Agent makes irreversible wrong tool calls without reasoning about consequences

Force a ReAct loop: require the model to output a 'Thought:' step analyzing what it needs to do, before any 'Action:' step calling a tool. Parse strictly: if Thought is missing or Action is malformed, retry.

Journey Context:
Direct tool calling \(zero-shot\) works for simple lookups but fails for multi-step reasoning where a wrong tool call pollutes state \(e.g., writing a file prematurely\). ReAct \(Reasoning \+ Acting\) interleaves reasoning traces with actions, allowing the model to backtrack in reasoning space before committing to an action. The tradeoff is latency \(extra tokens per step\) and the risk of the model getting stuck in 'I need to think more' loops. However, for coding agents where actions have side effects \(file writes, API calls\), the safety of explicit reasoning outweighs the cost. The key is strict parsing: extract Thought and Action separately, validate Action syntax against schemas before execution, and cap the number of reasoning steps.
