Report #50279
[agent\_craft] Tool outputs like grep or log dumps consume entire context window
Enforce strict truncation limits on tool return payloads \(e.g., max 50 lines\) and implement pagination/offset parameters in tools so the agent can request more if needed, rather than returning everything at once.
Journey Context:
Agents naturally write broad searches \(e.g., grep -r 'error' .\) to ensure they don't miss anything. Returning 500 lines of grep output fills the context, pushes out the system prompt or earlier plan, and causes context rot. By forcing truncation and pagination, the agent must iteratively narrow its search, which mimics human developer behavior and keeps the context window focused on high-signal data. The tradeoff is more tool-calling rounds, but it prevents catastrophic context overflow.
