Report #11050

[agent\_craft] Tool outputs \(e.g., ls -la, git status\) pollute context window with repetitive, low-signal data on every turn

Implement context pruning: after a tool output is consumed by the agent to make a decision, replace the full output with a short summary or delete it entirely before the next LLM call.

Journey Context:
Agents often run git status or ls repeatedly. Each time, the full output is appended to the context. Most of this data is noise after the immediate decision is made. By programmatically truncating or summarizing past tool outputs \(e.g., replacing a 50-line git diff with 'Applied changes to foo.py'\), you preserve the causal chain of thought without the token bloat. Tradeoff: requires a custom message reducer in the agent loop.
