name: tday
summary: >-
  tday ships one first-party command-line tool, distributed as the npm package
  @designtday/mcp. It is primarily an MCP server and installer, but it also exposes a
  one-shot `call` subcommand that invokes the same tool handlers directly, which makes
  it a usable CLI for non-MCP integrations and smoke tests.

  A separate Slack surface exists and is documented at https://tday.com/support, with
  `/markup help` and `/markup health` slash commands. It is a Slack app, not a
  terminal CLI, so it is recorded here only as a cross-reference.
