Report #98302

[agent\_craft] Context window fills with irrelevant files and the agent loses the thread

Pack context in this order: user request, files already read/edited, then candidate files ranked by semantic similarity to the query; truncate each file to the relevant functions plus 5 lines of surrounding context, not whole files.

Journey Context:
Dumping whole files is the default failure mode. It pushes out earlier conversation turns and causes the model to miss the actual bug. Semantic ranking \(embedding similarity to the query\) beats filename matching because the relevant fix often lives in an unexpectedly named utility. Truncating to relevant symbols plus a small window preserves line-number accuracy for edits while staying under budget. Keep the original full content retrievable via a second tool call if needed.
