Report #101538

[agent\_craft] Long contexts cause the agent to miss the needle-in-a-haystack detail needed for the fix

Run a retrieval/summarization step before the main prompt. Extract only the files, symbols, and snippets relevant to the query, and surface them explicitly in the agent's working context.

Journey Context:
LLM attention decays over long contexts; critical details in the middle are easily lost. The 'lost in the middle' effect means position matters as much as presence. Passive inclusion of entire files is inferior to active retrieval. When full files are unavoidable, place the most relevant sections at the start and end of the context window, not buried in the middle.
