* [Harnesses](/docs/resources/harnesses): agent runtime, model, and authentication.
* [Sandboxes](/docs/resources/sandboxes): compute and setup.
* [Secrets](/docs/resources/secrets): organization-scoped credentials.

Harnesses and sandboxes live in the factory file. Triggers refer to their local `key`.
Secrets live in the active organization; configuration uses names, never values.
