Report #14438

[agent\_craft] Stale tool execution outputs \(e.g., long stack traces\) rotting the context window

Implement context pruning: after a tool output is consumed by the LLM to make a decision, replace the full output with a concise summary or status \(e.g., replace 100-line stack trace with '\[Tool: TestRunner - 2 failures in auth.py\]'\).

Journey Context:
Agents keep the full history of tool inputs/outputs. A 200-line \`ls -la\` or a massive \`pytest\` traceback takes up massive context. Once the agent reads it and decides what to do, the raw output is dead weight. Truncating or summarizing past tool outputs prevents context overflow without losing the logical chain of thought.
