Report #17692

[agent\_craft] Summarizing conversation history collapses tool call/result pairs into generic descriptions, breaking the agent's ability to resume or retry failed tool calls

Never summarize tool call IDs or the exact JSON schemas of inputs/outputs. Maintain a separate 'scratchpad' for high-level summaries, but keep the raw tool call state for the current execution graph intact until the task step is fully resolved.

Journey Context:
Naive summarization treats the LLM context as a simple chat log. But agent loops are state machines. If you summarize 'I tried to write file X but got a permission error', you lose the exact error code and the exact file path needed for the retry tool call. You must separate episodic memory \(summarizable\) from working memory \(current tool execution graph, which must be exact\).
