Agent Skills
Agent Skills are a simple, open format for giving agents new
capabilities and expertise.
Skills are folders of instructions, scripts, and resources that
agents can discover and use to perform better at specific
tasks. Write once, use everywhere.

What are skills?
Agent Skills are a lightweight, open format for extending AI agent capabilities with
specialized knowledge and workflows.
At its core, a skill is a folder containing a SKILL.md file. This file includes metadata (name
and description, at minimum) and instructions that tell an agent how to perform a specific
task. Skills can also bundle scripts, templates, and reference materials.

# Required: instructions + metadata
# Optional: executable code
# Optional: documentation
# Optional: templates, resources
How skills work
Skills use progressive disclosure.
1. Discovery: At startup, agents discover and load the most relevant
just enough to know what it can do.
2. Activation: When a user asks an agent to perform a task, the agent loads the full SKILL.md
instructions into context.
3. Execution: At runtime, the agent executes the instructions, potentially using bundled files or
executing bundled scripts.
This approach allows agents to be more capable and adaptable on demand.
