Report #9087

[agent\_craft] Verbose tool outputs \(e.g., shell errors, directory listings\) consume context budget and obscure the actual signal

Post-process tool outputs before injecting them back into the context. Truncate to N lines, filter for errors, or use structured output flags \(e.g., ls -1 instead of ls -la, git diff --stat instead of git diff\).

Journey Context:
A common mistake is to dump raw stdout/stderr into the LLM context. A massive stack trace or a directory listing of 1000 files pushes out useful context and degrades the agent's reasoning. Agents should be equipped with tools that return concise, structured data, or an intermediate step must compress the output. For example, reading a huge CSV should return schema \+ 5 rows, not the whole file.
