sdk_count: 0
note: Underdog publishes no public API and ships no first-party API client SDK in any
  registry. The one first-party package found on npm is an internal web code style
  guide, not a client library, so no `SDKs` pointer is wired in apis.yml.

  note: Predominantly forks of third-party Ruby/infra projects (flipper, quickfix,
    console1984, mock_redis, openapi_first) plus internal tooling and hiring take-home
    templates. Notable original repositories are `lifecycle` (TypeScript, turns pull
    requests into ephemeral development environments), `background-agents` (TypeScript,
    an open-source background agents coding system) and `superpowers` (an agentic skills
    framework). None of them expose or document an Underdog API.
