Report #28789

[counterintuitive] Dumping the entire codebase or massive files into the prompt assuming 'more context is better'

Use targeted retrieval \(RAG\) and only include the exact signatures, types, and relevant snippets needed for the task.

Journey Context:
When context windows expanded from 4k to 128k\+, the instinct was to stuff everything. However, models suffer from the 'lost in the middle' phenomenon where they ignore information buried in long contexts. Over-stuffing also dilutes the instruction signal. A coding agent should act like a developer: read the relevant module interfaces, search for specific implementations, and keep the active context lean and highly relevant.
