Report #36849

[agent\_craft] Summarized error messages lose critical exact strings like variable names or line numbers needed for debugging

Never summarize tracebacks or exact logs. Extract the tail \(last 10-20 lines\) verbatim and pass it alongside the high-level summary.

Journey Context:
A summary like 'File not found error in auth module' is useless for debugging compared to 'FileNotFoundError: /etc/keys.pem'. Verbatim extraction of the terminal error ensures deterministic debugging steps can still be taken while the summary provides context.
