Agent Skills Index

Agent Skills Index
An agent skills index is a machine-readable list of reusable capabilities. The open Agent Skills specification defines a portable skill as a folder with a required SKILL.md file containing at least name and description, plus optional instructions, scripts, references, and assets.
Compatible agent runtimes discover and load skills from their package directories. A website can document or link to its published skill collection, but a generic website-wide discovery URL is not part of the Agent Skills specification. Do not invent one unless the consuming client documents support for it.
Common Skills
- Search products or docs
- Compare products
- Check price or availability
- Create a support ticket
- Retrieve account data after authentication
- Run a site audit
- Export reports or structured data
SEO Guidance
For Agent SEO, a skills index should be:
- Short enough for agents to parse quickly
- Linked from HTML and Link headers
- Consistent with your actual product capabilities
- Clear about authentication and user consent
- Kept separate from private or admin-only actions
