Report #82659

[agent\_craft] Summarizing past agent steps loses critical execution details like exact variable names or error strings

Use structured compaction instead of generic prose summarization. Extract exact code identifiers, error strings, and state transitions into a structured scratchpad or JSON state object.

Journey Context:
Generic LLM summarization is lossy and tends to abstract away the exact strings needed for code execution \(like my\_variable\_name or Error: ENOENT\). Agents need exactness. Structured state extraction preserves the tokens that matter for code generation while discarding conversational fluff, preventing hallucinated identifiers.
