  Provider-published Agent Skills for Twilio SendGrid. These are NOT generated by
  the API Evangelist pipeline — they are the SKILL.md files Twilio ships in the
  public github.com/twilio/ai repository under skills/sendgrid/, saved here
  VERBATIM (byte-for-byte as served by the GitHub contents API on 2026-08-13).
  Twilio announced them alongside the Twilio MCP server in "Introducing the
  Twilio MCP Server and Skills" (2026-05-07) and distributes them as the
  `twilio-developer-kit` plugin for Claude Code, Cursor and OpenCode.
  SendGrid is a Twilio company and its developer documentation is served from
  www.twilio.com/docs/sendgrid, so a SendGrid skill published in the Twilio AI
  repo is first-party.
