[agent\_craft] Summarizing conversation history loses critical technical details like exact error messages and variable names

Use structured summarization templates that explicitly preserve verbatim: \(1\) exact variable and function names, \(2\) error messages and stack traces, \(3\) constraints and requirements, \(4\) current file paths and line numbers. Never compress code-specific facts into generic prose.

Journey Context:
When context fills up, agents summarize earlier conversation to free space. The common and costly mistake is using generic summarization that converts specific technical details into vague prose—'the user mentioned some error' instead of 'TypeError: Cannot read property map of undefined at line 42 in UserList.tsx.' This destroys the precise signal needed for accurate code generation and debugging. The tradeoff is between compression ratio and information preservation. Structured templates sacrifice some compression but preserve the facts that actually matter for coding. Unstructured summarization might achieve 10x compression but at the cost of repeatedly re-asking the user or making wrong assumptions about names and values.
