Preferred managed route
Publish the open-source Corvio Agent Plugin to Cursor Marketplace. It carries the two reviewed Skills and the standard Streamable HTTP MCP definition; Cursor performs manual review before listing.
Work mode is not Code mode
Grok Build can load Claude-compatible skills, plugins, MCP configuration, and AGENTS.md locally. Grok Bot instead runs as a hosted teammate with its own cloud computer, connected apps, skills, routines, and memory. Passing in Grok Build does not prove the same package is visible to Grok Bot.
Acceptance after listing
Install Corvio from Cursor Marketplace into a test Bot, complete OAuth, verify list_workspaces and one recognized document, then perform and read back one reversible write. Until that evidence exists, report the source as marketplace-ready but external-pending, and do not expose the Bot as an @-mention listener.
