Report #54496

[agent\_craft] Agent loads a massive project context or repo map into the system prompt, pushing the actual user query out of the LLM's immediate attention window

Keep the system prompt minimal and skeletal. Inject project context dynamically as a tool result or user message only when the agent actively queries for it.

Journey Context:
System prompts are processed on every single turn. If it is 50k tokens of repo map, you waste tokens and degrade attention \(recency bias favors the end of the context\). Dynamic injection \(RAG\) ensures only relevant context occupies the window, and it naturally sits closer to the agent's current reasoning step.
