## What Agents Can Do

- Explain what Yellowstone Sound Atlas is and when it is useful.
- Fetch the route JSON and enumerate specimens by title, theme, zone label, description, credit, and source audio path.
- Link users to the playable atlas or to a specimen share page under `/atlas/share/{id}/`.
- Cite the project as a static, unofficial listening atlas built from public Yellowstone sound library materials.

## Truth Boundary

- YSL has no account system, OAuth flow, private user data, payment flow, write API, webhook system, MCP server, A2A agent endpoint, or autonomous action surface.
- The OpenAPI file documents only public, read-only static resources served by the website.
- This is not an official National Park Service product. Source labels state the files are public domain, but downstream users should verify rights for their own use.
