Agent catalog identity
The public agent catalog returns discoverable agents. A catalog item is not runnable by itself. It becomes a runnable project agent when you install it into a project or fork a template project into project source. Use these fields for catalog behavior:| Field | Meaning |
|---|---|
kind | The catalog identity kind. template_agent items are forkable project-agent templates. installable_agent items can be installed before use. |
actions | The actions available to the current caller. Current project flows use fork for template agents and install for installable agents. |
template_project | Present for template_agent items. Contains the project reference and source path used by the fork flow. |
installability | Present when install state is project-contextual. Use it to show whether an installable agent can be installed, is already installed, or is unavailable. |
card for rendering discovery surfaces. Treat the card as metadata only: provider, version, availability, runtime mode, runtime service key, modes, skills, and tools.
Project agent lists return runnable project agents. Use kind: "source_project_agent" or kind: "installed_project_agent" plus can_run for behavior. Project agent lists also include runtime_readiness so clients can show whether an installed runtime-backed agent is ready, offline, unknown, or not applicable.
Runtime readiness does not replace authorization. Installed catalog agents still run through project access grants and run-scoped service-account tokens.
Agent run responses include run_snapshot, a durable projection of the selected project-agent identity, source/catalog provenance, runtime target, and requester.
Steps
- Define the agent and its purpose.
- Attach prompts, tools, and skills.
- Connect the agent to conversation flows when it needs chat state.
- Expose project actions through MCP when assistants need tool access.
