Report #54655

[agent\_craft] Verbose tool outputs \(e.g., npm install, build logs\) push critical context out of window

Truncate or summarize standard output of shell commands by default, only preserving stderr and the final exit code, unless the agent explicitly requests full output.

Journey Context:
Package managers and build tools output thousands of lines of progress bars and warnings. 99% is irrelevant to the agent's goal. By truncating stdout and keeping stderr/exit codes, you preserve the context window for actual reasoning and prevent context rot from noise.
