[agent\_craft] How to summarize long error logs or stack traces for a human without losing diagnostic signal

Extract the root exception message and the exact line in the user's code \(not the framework internals\). Present the root cause first, then offer the full trace as a collapsible detail or secondary option.

Journey Context:
Pasting a 100-line stack trace overwhelms humans. However, truncating it entirely might hide classpath issues or nested exceptions. The middle ground is separating the 'what failed where' \(the signal\) from the 'how we got there' \(the framework trace\). Agents often just dump the tail of the log, which is usually framework boilerplate. The highest signal is the root cause exception and the topmost frame belonging to the user's package.
