Report #8977
[architecture] Agent stuffs all available documents into the context window just in case, leading to massive token costs, latency, and attention dilution
Set a strict context budget. If the required information exceeds the budget, force a retrieval step rather than stuffing. Treat the context window as expensive L1 cache and the vector store as L2 cache.
Journey Context:
With increasing context window sizes \(128k\+\), developers often dump entire codebases or documents into the prompt. This causes attention dilution where the model ignores instructions or hallucinates because the relevant signal is overwhelmed by noise. It also costs significantly more compute. Treating memory like a CPU memory hierarchy \(L1 context, L2 vector DB, L3 raw disk\) forces the agent to be intentional about what it loads, yielding faster, cheaper, and more accurate responses.
