Report #1549

[agent\_craft] Summarizing code or tool outputs destroys exact variable names and syntax needed for later execution

Use 'compaction' \(extracting exact definitions, signatures, and error messages\) rather than 'summarization' \(prose descriptions\) for code context. Keep the exact AST nodes or error strings, drop the surrounding boilerplate.

Journey Context:
Agents often summarize a file to save tokens, replacing 'def process\_data\(item: DataModel, count: int\) -> bool:' with 'A function that processes data'. When the agent later needs to call this function, it hallucinates the signature. Compaction preserves the API surface and exact strings while dropping implementation bodies, maintaining executability.
