Report #13203

[agent\_craft] Agent misses critical details or instructions in long context window

Place critical instructions and target code at the very beginning or end of the context window. Avoid relying on the model to extract specific facts from the middle of large text dumps.

Journey Context:
LLMs exhibit a 'U-shaped' performance curve over long contexts \(Lost in the Middle\). When an agent dumps a 10k-line file into the context and asks to modify a function in the middle, it often hallucinates or misses constraints. Instead, structure context so the most important instructions and the specific code to edit are at the edges, or chunk the retrieval to only inject the necessary 500 lines.
