Additional notes for reviewers
Submitted by the SuperMailOS team (affiliated with the service; SuperMailOS is a paid email host with a free trial).
- Agent Plugins layout at the repo root:
plugin.json+mcp.json(onestreamable-httpserver,https://supermailos.com/mcp) and five skills underskills/. It installs withcopilot plugin marketplace add SuperMailOS/pluginandcopilot plugin install supermailos@supermailos. - Auth: OAuth 2.1 sign-in discovered from the server's
401(RFC 9728 metadata, dynamic client registration). No secrets in the repo. - Safety: the skills default to drafts, send only on an explicit request, never mark mail read unless asked, and treat email content as untrusted (never as instructions).
- Checked before submitting:
@microsoft/vallylint passes for all five skills, and the Copilot CLI install works from a local copy of this commit.
