## 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.

# CloudBase Document Database WeChat Mini Program SDK

## Activation Contract

### Use this first when

- A WeChat Mini Program must access CloudBase document database through `wx.cloud.database()`.
- The request mentions Mini Program collection CRUD, pagination, aggregation, or geolocation queries.

### Read before writing code if

- The task is Mini Program database work but you still need to separate it from Web SDK, cloud functions, or SQL tasks.
- The request depends on built-in user identity, `_openid`, or Mini Program-side permissions.

### Then also read

- Mini Program project rules and CloudBase integration -> `../miniprogram-development/SKILL.md`
- Mini Program auth and identity flow -> `../auth-wechat-miniprogram/SKILL.md`
- Browser-side document database code -> `../cloudbase-document-database-web-sdk/SKILL.md`

### Do NOT use for

- Browser/Web code using `@cloudbase/js-sdk`.
- Server-side or cloud-function database access.
- MySQL / relational database work.

### Common mistakes / gotchas

- Copying Web SDK code into Mini Program pages.
- Manually writing `_openid` during create or update operations.
- Assuming built-in Mini Program identity means security rules can be ignored.
- Mixing collection CRUD and backend-wide admin workflows in the same client path.

### Minimal checklist

- Confirm the caller is a Mini Program page/component or Mini Program-side logic.
- Initialize `wx.cloud` correctly before database calls.
- Verify whether the collection rules rely on `auth.openid` / `_openid`.
- Read the specific companion reference file for the operation you need.
