Additional notes for reviewers

This is the official Spacefast plugin maintained by Automattic Inc. It includes seven skills: setup, build-website, spacefast (publish), edit-space, share-space, custom-domain, and fix-deployment.

The plugin uses Agent Plugins 1.0 with a hosted Streamable HTTP MCP connection at https://mcp.spacefast.com. Hosted access requires a Spacefast account and browser OAuth. The README also documents anonymous CLI publishing as a separate workflow. Interactive Apps and other host features are used only when the host supports them.

Install directly with copilot plugin install spacefast/plugins. The bundled skills cover publishing, source editing, sharing, domains, and recovery, including server approval and revision requirements. Live publishing and account mutations were not exercised for this submission.

The hosted server is published in the Official MCP Registry as io.github.spacefast/mcp, version 0.5.1. Setup and registry metadata: https://github.com/spacefast/mcp. Documentation: https://spacefast.com/docs/. Contact: fatih.akin@automattic.com.

    A note on the manifest warning: this commit includes the Agent Plugins 1.0 root plugin.json and the matching root mcp.json. The .plugin/plugin.json file is also present for compatibility; the intake check selected that file first.

    I also checked a fresh copilot plugin install spacefast/plugins with Copilot CLI 1.0.93-1 in an isolated profile. All seven skills and the Spacefast MCP connection loaded as enabled. The installed files matched the submitted commit. This check did not run OAuth or make changes through the hosted tools.
