Context Budget
Domain: Memory & Context
Motivation
The total context space available. The agent must budget it across system prompt, memory, conversation, and files. Running out means compression or loss.
Concrete Example
Budget: 128K tokens. System prompt: 2K, memory: 5K, conversation: 100K, files: 21K. Total: 128K. If conversation grows, something else must shrink (compression).
Analogy
A monthly allowance - you budget across food, transport, and fun. If one grows, another shrinks. Context budget allocates tokens across all context sources.
