Report #4797

[agent\_craft] Context window filled with irrelevant files and stale conversation, causing the model to miss the actual bug

Curate the working set: read only files directly relevant to the current change, summarize long outputs, and reset or narrow the goal when the session drifts.

Journey Context:
LLM attention is finite. Every extra file competes with the bug. Agents often follow import chains too deep or paste whole stack traces. Instead, start at the entry point, read one or two layers, and expand only when blocked. Parallel reads help only if the set is small; ten unrelated files are worse than two focused ones.
