[agent\_craft] Dumped a huge file into context and the model missed the key detail in the middle

Keep retrieved context focused; put the most relevant facts near the end of the prompt and avoid dumping entire files.

Journey Context:
LLM retrieval is not uniform over the context window. The 'Lost in the Middle' study shows that performance degrades when relevant information sits in the middle of long inputs, even for models with large context windows. Agents commonly paste whole files 'just in case,' but this actively hides the needle. The fix is deliberate curation: grep to find the right region, read only the relevant block, and summarize long histories before passing them forward. For coding agents, prefer targeted Read ranges over whole-file dumps, and surface conclusions \(e.g., 'the bug is on line 47'\) rather than raw transcripts.
