[agent\_craft] Dumping full tool output into context wastes tokens and drowns the signal

Pre-filter command output with head, tail, grep, or line ranges; return only the excerpt the next reasoning step actually needs.

Journey Context:
When a test log, directory listing, or search result is long, the easy move is to paste it all into the model context. But LLM reasoning degrades when important details are buried in noise, and large outputs accelerate context-window pressure. The ReAct framework treats each observation as an input to the next reasoning step, which implies observations should be concise and relevant. Alternatives like asking the model to 'ignore irrelevant lines' are unreliable because attention is not a perfect filter. The right call is to use shell primitives to extract the signal at the source, mirroring how engineers skim logs.
