Report #6214

[architecture] Agent runs out of context or loses track of instructions because it stuffs all available context into the prompt instead of using external memory

Use the context window strictly for the current task, active instructions, and recent trajectory. Move long-term knowledge and historical logs to a vector store or relational DB, retrieving only what is semantically relevant to the current step.

Journey Context:
Developers often treat the LLM context window as a database, dumping entire codebases or chat histories into it. This leads to attention dilution \(the 'lost in the middle' phenomenon where LLMs ignore middle context\) and token limit crashes. The context window is working memory: fast but volatile and limited. Vector stores are long-term memory: they scale but require explicit retrieval. The right call is a two-tier memory system: working context for 'what I am doing now', and external retrieval for 'what I might need to know'.
