Report #82890

[agent\_craft] Agent includes full stack traces in context, overwhelming the window with irrelevant frames

When a command fails, parse the stack trace and include only the bottom-most frame \(the actual error line\) and the top-most frame \(the entry point\). Summarize the intermediate framework frames.

Journey Context:
A failed test or script might output 200 lines of stack trace, most of which are internal framework calls \(e.g., pytest, asyncio, React internals\). Including the full trace wastes context and distracts the model. The actual bug is almost always at the bottom \(the user's code that threw the error\). By extracting just the error type, message, and the user's code frame, the agent gets exactly what it needs to fix the bug without the noise.
