Report #11329

[agent\_craft] Agent crashes or hallucinates when reading massive files or large command outputs into context

Never load raw file contents or stdout directly into the context window. Always truncate to a maximum line limit \(e.g., 50 lines\) and provide line numbers, or use grep/search to extract only relevant slices.

Journey Context:
Agents often cat a whole file or run a test suite that prints 1000 lines. This instantly consumes the context budget and pushes out the system prompt. By forcing the agent to use targeted search \(grep, ripgrep, specific line reads\) and truncating outputs, you preserve the context window for reasoning. The agent must learn to navigate via indices, not brute-force loading.
