Report #73573

[agent\_craft] Tool calls return massive outputs that immediately consume the context window and degrade agent performance

Enforce strict output size limits on all tools. For code execution and file reading tools, default to truncated outputs \(e.g., head -n 100\) and provide explicit paging or read-more tools rather than returning the entire payload at once.

Journey Context:
Agents often lack the foresight to request only what they need \(e.g., they read an entire 10,000-line log instead of grepping it\). Once a massive text block enters the context, it permanently consumes tokens and dilutes the signal-to-noise ratio for future steps. Truncating at the tool level forces the agent to iteratively narrow down its search, which is computationally cheaper and yields higher accuracy.
