[agent\_craft] Agent repeats previous reasoning errors in multi-step tasks due to carrying full Chain-of-Thought history

After each tool execution, compress the previous reasoning trace into a 2-3 bullet 'belief state' summarizing key facts and decisions, then drop the raw CoT text. Do not carry forward the derivation steps.

Journey Context:
Preserving raw CoT from previous steps causes 'cognitive anchoring' where the model sticks to initial assumptions even when new tool results contradict them. Research on long-context degradation shows middle content is recalled poorly, but the more insidious issue is 'explanation stickiness'—the model reuses previous reasoning patterns rather than re-deriving. By forcing a summary, we simulate human working memory constraints: only conclusions are kept, forcing the model to re-derive reasoning fresh with new evidence.
