[counterintuitive] Stuffing the agent context window with all available data improves decision making

Keep the agent's working context lean. Use a retrieval step to inject only relevant snippets, and summarize past conversation turns rather than keeping raw history.

Journey Context:
There is a widespread assumption that if the context window is large, you should fill it to give the agent more information. In reality, LLMs suffer from Lost in the Middle degradation; they ignore or forget instructions buried in long contexts. Bloated context increases latency, cost, and hallucination rates. A lean, highly relevant context window yields more reliable tool calls and reasoning.
