Marketplace overview

The Marketplace at /org/{slug}/marketplace is Harmony's hub for things you can connect to or reuse with Companion. It includes AI Skills, agent prompts, third-party app connectors, installed integrations, and the catalog of LLM models available to the workspace.

To open it, click Companion in the sidebar, then select Marketplace.

Marketplace tabs​

The Marketplace is organized into six tabs. Discover is the default tab and shows curated CMS sections, including collections, featured Skills, agents, and connectors. Skills contains reusable Companion prompts that you can browse, copy, or download. Agents contains curated agent prompts that represent the agent behavior Harmony is building toward.

The Apps tab is the live integrations browser for workspace and personal connectors. Models shows the AI models registered for the workspace, along with capability indicators. Installed shows the workspace and personal integrations that are currently connected.

Skills​

Marketplace Skills are reusable Companion prompts, sometimes with connector expectations. Each Skill detail page shows the prompt rendered as Markdown, and that prompt is the actual text you can use. The page may also include a screenshot gallery, version details, author information, category metadata, and a Download button.

There is no in-app Install button for Marketplace Skills today. To use one, copy the prompt into a Companion thread or download the bundle for reference. If the Skill should become available to the whole workspace, copy the prompt into a workspace Protocol under Settings -> Protocols.

For more on Skills, see Skills overview. For workspace-scoped Skills, see Creating custom Protocols.

Agents​

The Agents tab lists CMS-curated agent prompts. Each detail page includes a hero card, the agent prompt in Markdown, categories, author metadata, and a Download button.

The standalone Agents sidebar entry is currently disabled and shows a Soon badge. Harmony does not yet provide a per-workspace agent registry, one-click agent installation, or installed-agent listing. To use an agent today, open its detail page, copy the prompt, and run it in a Companion thread or save it as a Skill.

Apps​

The Apps tab is the live integrations browser. Unlike Skills and Agents, it is not only a CMS catalog. It shows providers that can be connected to Harmony, including workspace-scope integrations such as HubSpot, Salesforce, and Slack, as well as personal-scope integrations such as Google Calendar, Linear, and Todoist.

The Apps page includes recommended providers, categorized provider tiles, connection status, and management actions. A provider tile shows the provider's logo, display name, description, category, and connection button. If an integration is already connected, the tile shows its connected state and a management action instead. Catalog entries that are not available yet show a Coming soon tag.

Workspace-scope integrations require integrations:read:all to view the workspace integration section and integrations:write:all to install or disconnect integrations. The provider may also request OAuth scopes during connection. Personal-scope integrations are tied to your user account and do not require workspace integration permissions.

For per-integration setup details, see Workspace integrations and Personal integrations.

Models​

The Models tab lists every AI provider registered for the workspace. Models are grouped by provider, and each card represents a specific model.

Capability indicators show what each model supports. The eye icon means the model supports vision. The wrench icon means the model supports tools or function calling. The sparkles icon means the model supports reasoning. The context window indicator shows the model's context size, such as 128K or 1M. A model can also show a Default badge when it is the workspace default.

The Models tab is informational. You can preview model details from this tab, but you cannot install a model or change the workspace default here. Default model selection and per-feature overrides are managed in Settings -> Intelligence. See Intelligence.

Installed​

The Installed tab shows connected integrations in a grid. It includes both workspace and personal integrations, but it does not include Marketplace Skills or Agents today.

Clicking an installed integration tile opens that integration's manage page. If no integrations are connected, the empty-state link points back to the Apps marketplace so you can browse available providers. Workspace integrations use the integration's providerName as the display name when it is set, which helps distinguish multi-instance integrations such as multiple Gmail accounts.

To disconnect an integration, open its manage page from the Installed tab or the Apps tab and use the Disconnect action.
