Introduces 'Agent Skills' as an open standard for equipping AI agents with domain-specific expertise. Agent Skills are organized folders containing instructions, scripts, and resources that agents can dynamically discover and load. The system utilizes progressive disclosure, with a `SKILL.md` file containing metadata and detailed instructions, and the ability to bundle additional files for deeper context. Skills can also include executable code for deterministic operations.
