Charm Store is the user-facing marketplace for published Charm agents.

​
What Users See

Store listings can include:
  • agent name and description,
  • author,
  • tags,
  • pricing,
  • supported inputs,
  • run history or app UI,
  • OAuth requirements,
  • install or execute actions.
Users can also access the Community Plugins Registry via the top navigation bar to discover custom runtimes, adapters, and tools built by the open-source community.

​
What Developers Publish

Developers publish an agent bundle and manifest with: 
charm push .
The Store reads metadata from charm.yaml, including:
  • persona,
  • pricing,
  • interface,
  • auth,
  • runtime.

​
Execution

When a user runs an agent, the Store sends the request to the runner. The runner validates auth, billing, runtime mode, environment variables, and bundle location before starting execution.

​
Developer Checklist

  • Use clear names and descriptions.
  • Keep input fields understandable for non-technical users.
  • Validate the manifest before publishing.
  • Test the Store page after publishing.
Continue with Publish.
