## Standalone Install Note If this environment only installed the current skill, start from the CloudBase main entry and use the published `cloudbase/references/...` paths for sibling skills. - CloudBase main entry: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/SKILL.md` - Current skill raw source: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/auth-nodejs/SKILL.md` Keep local `references/...` paths for files that ship with the current skill directory. When this file points to a sibling skill such as `auth-tool` or `web-development`, use the standalone fallback URL shown next to that reference. ## Activation Contract ### Use this first when - Node.js code in cloud functions or backend services must read caller identity, look up users, or issue custom login tickets. - The backend responsibility is auth / identity, not provider setup or frontend login UI. ### Read before writing code if - The task mentions `@cloudbase/node-sdk`, server-side auth, custom login tickets, or "who is calling". - The request mixes frontend login with backend identity logic; split the flow and route client-side work elsewhere. ### Then also read - Provider setup / publishable key -> `../auth-tool/SKILL.md` (standalone fallback: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/auth-tool/SKILL.md`) - Web login UI that consumes custom tickets -...
