- Include `name`, `version`, and `description`
- Include `supportedInterfaces` with service URL and transport protocol
- List `capabilities` and `skills` (each with `id`, `name`, `description`)
See [Agent Discovery](https://a2a-protocol.org/latest/topics/agent-discovery/)
for the full schema.
## Cloudflare

A2A-compatible agents on Workers.
