Report #95887

[agent\_craft] Tool returns massive output that exceeds context limits or pushes out system prompt, causing agent amnesia

Enforce strict output truncation limits on all tool executions \(e.g., head -n 100 or post-processing truncation\) and return a 'truncated' flag to the agent so it knows it can request specific line ranges.

Journey Context:
Agents often run commands that return thousands of lines \(logs, large JSON files\). This instantly fills the context window, pushing out the system prompt and causing the agent to forget what it was doing. Uncontrolled tool output is the fastest path to context rot. By strictly truncating tool outputs and signaling truncation, you force the agent to use targeted commands \(like grep or specific line reads\) to find what it needs, keeping the context lean and focused.
