context-fundamentals

Context engineering structures how AI models process system prompts, tool definitions, message history, and retrieved documents. It manages these components to ensure agents operate efficiently within attention mechanism limits.

Progressive disclosure optimizes the LLM context window by loading information only when needed. This strategy manages context budgeting by prioritizing relevant tool outputs and retrieved documents over excessive message history.

AI agent performance degrades with growing conversation history due to attention mechanism limitations and context window constraints. Effective context budgeting manages message history to prevent overwhelming the model.

Balancing context quality versus quantity in prompt engineering requires structuring system prompts and tool definitions efficiently. Prioritize progressive disclosure and relevant tool outputs over loading excessive retrieved documents.

Attention mechanisms limit context budgeting by restricting how much information an LLM processes effectively. These constraints demand careful management of tool definitions, retrieved documents, and message history to maintain performance.
