The paper behind the U-shaped recall curve: models attend to the start and end of a long context and lose the middle.
Listed inWhat is a Context Layer?Context Engineeringon
One place in the codebase that decides what goes into every prompt. The limit that binds is the model's attention rather than the size of the context window, so the layer curates what it sends instead of filling the space available.

Wrong answer or missing context? Precision has a reference-free variant you can run today; recall always needs ground truth.

Five things make up the payload, and each is a decision with its own failure. Tool definitions are billed on every call whether used or not.

The curve is U-shaped and the middle is the weak spot, even for models trained for long context. Where to put what matters.

The context an assistant needs for warehouse data is metadata, not rows. Certification is what makes it trustworthy enough to act on.
Listed inContext IsolationContext Engineeringon
Running a sub-task in its own context window keeps its exploration out of the main conversation, which can return a short result from a long search. The same separation is a normative rule in the Model Context Protocol, and it costs the caller information the sub-task never reports.

Twenty turns into a booking, six settled facts are what the model needs and the transcript is an inefficient way to carry them. Trimming a turn per request can also cost more than sending everything, because it breaks the cache.

Docs, databases, tickets, telemetry, and the user's own session.

Short-term, episodic, and semantic memory across sessions.
