Report #80142

[agent\_craft] Agent produces verbose chain-of-thought that leaks into final output or exhausts context window

Use "inner monologue" pattern: wrap reasoning in tags that are stripped before execution, or use separate reasoning and answer prompts with stop sequences. Never allow raw CoT to reach the tool executor.

Journey Context:
CoT helps for complex logic but agents often concatenate reasoning with code, causing syntax errors. The tag approach \(used by Claude Code and OpenAI's research\) isolates reasoning. Alternative is two-pass: first generate plan, then code. But that doubles latency. Tag-based separation is optimal for agents that need speed and correctness. Common mistake: forgetting to actually strip the tags before passing to interpreter.
