FAQPage Schema
What is context engineering for AI agents?

Context engineering for AI agents involves managing system prompts, tool definitions, and message history within the context window to optimize decision-making and agent performance.

How does progressive disclosure work in AI agent systems?

Progressive disclosure in AI agent systems works by loading information into the context window only as needed, conserving the attention budget and preventing context overflow during complex tasks.

How do I manage the context window when designing an AI agent?

Manage the context window by budgeting attention, structuring system prompts, and controlling message history length to ensure the agent processes retrieved documents and tool outputs effectively.

What is an attention budget in prompt engineering?

An attention budget in prompt engineering represents the finite capacity of the model's attention mechanism, requiring careful context budgeting to prioritize system prompts and tool definitions over less critical history.

Why does my AI agent ignore instructions in the system prompt?

An AI agent may ignore system prompt instructions due to context budgeting issues, where excessive message history or tool outputs overwhelm the attention mechanism and push critical directives out of focus.
