Report #30598

[agent\_craft] Tool outputs like ls -R or git log flooding the context window with noise

Enforce strict output formatting and truncation in tool definitions \(e.g., git log --oneline, ls -1\), and pipe large outputs to head or write a parsing script instead of returning raw stdout.

Journey Context:
Agents often run commands that return thousands of lines. If the tool returns all of it, the context window fills up instantly, causing context rot and high cost. The tool definition itself must mandate concise outputs, or the agent must be prompted to use flags that reduce verbosity. Better yet, write specialized tools that inherently return structured, bounded data.
