notes: >-
  OpenSpec ships a single first-party npm package that installs the `openspec`
  CLI binary; there is no client SDK because OpenSpec has no HTTP/REST API
  (the docs state "no API keys, no MCP required"). The legacy unscoped `openspec`
  npm package (last published 2022, owner openspecio) is unrelated to this project.
