Principles
1. Concise is Key
The context window is a shared resource. Only add context the agent doesn't already have. Challenge each piece of information: "Does the agent really need this explanation?"
2. Progressive Disclosure
Structure skills for efficient context use:
- Metadata (~100 tokens):
nameanddescriptionloaded at startup - Instructions (.md`
