Report #68361

[agent\_craft] Retriever injects semantically similar but task-irrelevant code chunks, hijacking the agent's current step

Use the agent's current step or plan as the retrieval query, not the user's original prompt. Apply a cross-encoder reranker or relevance threshold before injection.

Journey Context:
Naive RAG embeds the user's initial message. In a multi-step agent trajectory, the user's message is stale context. The agent needs chunks relevant to step 5 of its plan, not step 1. Without step-aware retrieval, you get context poisoning where the agent abandons its current sub-task to chase a tangentially related concept from the retrieved chunk.
