Report #16425

[agent\_craft] Agent retrieves too many code snippets, diluting the useful context with noise, leading to worse generation than no context at all

Apply a strict relevance threshold and limit retrieval to top-k \(where k is small, e.g., 3-5\). If no chunk passes the threshold, return nothing rather than forcing a low-signal retrieval.

Journey Context:
The 'more context is better' fallacy. Adding 10 marginally related files to the context window degrades the LLM's attention on the 1 highly relevant file \(context dilution\). It is better for the agent to ask for clarification or use a different search tool than to pollute its window with low-signal code. Setting a high similarity threshold ensures precision over recall for in-context learning.
