Report #1573

[agent\_craft] Command execution tool outputs massive logs, overwhelming the context window and degrading subsequent reasoning

Enforce strict truncation and tailing on tool outputs. Cap stdout/stderr at a fixed token limit \(e.g., 2000 tokens\). If the exit code is non-zero, prioritize the tail of stderr over stdout, as the error message is usually at the end.

Journey Context:
Agents often run commands like \`npm install\` or \`cat large\_log.txt\`. Including the full output wastes context tokens and dilutes the signal. Naive truncation from the start hides the actual error. Tailing stderr is the right tradeoff because shell errors propagate to the bottom, while successful outputs usually just need confirmation or the final few lines of progress.
