## Sibling skills (local only) Sibling CloudBase skills ship beside this skill. Use local relative paths such as `../auth-tool-cloudbase/SKILL.md`. If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do **not** HTTP-fetch remote skill or protocol markdown into the agent context. ## Activation Contract ### Use this first when - The task is a CloudBase Web login, registration, session, or user profile flow built with `@cloudbase/js-sdk` and the auth provider setup has already been checked. ### Read before writing code if - The user needs a login page, auth modal, session handling, or protected Web route. Read `auth-tool-cloudbase` first to ensure providers are enabled, then return here for frontend integration. ### Then also read - `../auth-tool-cloudbase/SKILL.md` for provider setup - `../web-development/SKILL.md` for Web project structure and deployment ### Do not start here first when - The request is a Web auth flow but provider configuration has not been verified yet. - In that case, activate `auth-tool-cloudbase` before `auth-web-cloudbase`. ### Do NOT use for - Mini program auth, native App auth, or server-side auth setup. ### Common mistakes / gotchas - Skipping publishable key and provider checks. - Replacing built-in Web auth with cloud function login logic. - Reusing this flow in Flutter, React Native, or native iOS/Android code. - Creating a detached helper file...
