1## Sibling skills (local only)
2 
3Sibling CloudBase skills ship beside this skill. Use local relative paths such as `../auth-tool-cloudbase/SKILL.md`.
4 
5If 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.

7## Activation Contract
8 
9### Use this first when
10 
11- 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.
12 
13### Read before writing code if
14 
15- 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.
16 
17### Then also read
18 
19- `../auth-tool-cloudbase/SKILL.md` for provider setup
20- `../web-development/SKILL.md` for Web project structure and deployment
21 
22### Do not start here first when
23 
24- The request is a Web auth flow but provider configuration has not been verified yet.
25- In that case, activate `auth-tool-cloudbase` before `auth-web-cloudbase`.
26 
27### Do NOT use for
28 
29- Mini program auth, native App auth, or server-side auth setup.
30 
31### Common mistakes / gotchas
32 
33- Skipping publishable key and provider checks.
34- Replacing built-in Web auth with cloud function login logic.
35- Reusing this flow in Flutter, React Native, or native iOS/Android code.
