Report #73694

[agent\_craft] Agent generates verbose free-form reasoning that digresses from the goal or exceeds token limits in chain-of-thought

Constrain Chain-of-Thought with a strict template: 'PLAN: \[numbered steps\]\\nVERIFY: \[constraint checks\]\\nEXECUTE: \[tool call or final answer\]'. Strip any text outside these tags before parsing.

Journey Context:
Free-form CoT \('Let's think step by step...'\) often produces digressive text, repeats the problem statement, or generates 'hallucinated confirmation' where the model convinces itself of a wrong path. Structured CoT \(similar to Tree of Thoughts or ReAct with strict formatting\) forces the model to externalize planning in a verifiable, machine-readable way. The 'VERIFY' step specifically catches constraint violations before execution, preventing the 'oops, I forgot I couldn't do that' backtracking loops.
