Package and MCP availability

Default npm commands select stable through latest. The next channel is opt-in preview. Check the live agent context for the served release and current npm publication, or follow agent updates.

Our GitHub marketplace is self-published, not an Anthropic directory listing. Follow the Claude plugin installation walkthrough or update an existing plugin. The @extrovert suffix names the marketplace, not an npm tag. Claude plugins install the published GitHub plugin files and use hosted MCP, not npm @next or @latest. Choose one plugin per host session to avoid duplicate registrations. Assistant does not include account administration or commerce. See Email Assistant for its boundary and connection steps.

The eleven standalone full-capability skills are grouped by task:

• Design and integrate: agent-email-architecture, extrovert-sdk
• Connect: extrovert-connect
• Read and verify: extrovert-read-inbox, wait-for-otp
• Reviewed outbound mail: extrovert-send-email, extrovert-writing-rules
• Explicit full administration: extrovert-admin
• Feedback and support: extrovert-support

Preview access

Use @next only when deliberately choosing a preview feature or fix. For a reproducible installation, select an exact published version. See preview access and returning to stable.

The repository manifest is the source of truth for the skill list and tool authorization rows. Third-party indexing can lag publication and is not a release or integrity signal.

Check live signup availability with agent_context or GET /v1/signup-status; it is independent of package availability. Existing agent keys, enrollment keys and existing accounts continue to work. Older hosted OAuth connections must reconnect through explicit consent. Choose identity, reach, actions, and duration using Connections and access; existing inbox ownership is preserved.
