description: CloudBase platform overview and routing guide. This skill should be used when users need high-level capability selection, platform concepts, console navigation, or cross-platform best practices before choosing a more specific implementation skill.

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.

**Cross-cutting protocols** (required before code changes or deployments):

• Change Safety Protocol: `references/protocols/change-safety-protocol.md`
• Deployment Gate: `references/protocols/deployment-gate.md`
• Sensitive Runtime Data Protection: `references/protocols/sensitive-runtime-data-protection.md`

**Post-deployment (optional, non-intrusive)**: after a deployment is verified successful, you may offer at most once to generate anonymized shareables (Deployment Share) — see `references/protocols/deployment-share.md`. Never follow up if declined; never publish on the user's behalf.

Activation Contract

Use this first when

• The user asks which CloudBase capability, service, or tool to use, or needs a high-level understanding of hosting, storage, authentication, cloud functions, or database options.
• The task is about console navigation, cross-platform differences, permission models, or platform-level best practices before implementation.

Read before writing code if

• It is still unclear whether the task belongs to Web, mini program, cloud functions, storage, MySQL / NoSQL, or auth.
• The response needs platform selection, conceptual explanation, or control-plane navigation more than direct implementation steps.

Then also read

• Minimal Web + database demo (BaaS-first, no cloud functions by default) -> `../minimal-web-baas-demo/SKILL.md`
• **Stack order for 最小前后端 / Lovable-like demos:** Web SDK CRUD > MCP schema > template warmup during credential wait > cloud functions (default count = 0). Capability sniff: connector ready → `envQuery` → lock one DB plane → MCP schema → `@cloudbase/js-sdk` CRUD → preview.
• Web app implementation -> `../web-development/SKILL.md`
• Web auth and provider setup -> `../auth-tool-cloudbase/SKILL.md`, `../auth-web-cloudbase/SKILL.md`
• Mini program development -> `../miniprogram-development/SKILL.md`
• WeChat Pay, Official Account OAuth, JSAPI Pay, or Native QR-code Pay through CloudBase Integration Center -> `../cloudbase-wechat-integration/SKILL.md` (official docs: `https://docs.cloudbase.net/integration/introduce.md`)
• Cloud functions -> `../cloud-functions/SKILL.md`
• Official HTTP API clients -> `../http-api-cloudbase/SKILL.md`
• Document database -> `../cloudbase-document-database-web-sdk/SKILL.md` or `../cloudbase-document-database-in-wechat-miniprogram/SKILL.md`
• CloudBase PostgreSQL / PG -> `../postgresql-development-cloudbase/SKILL.md`
• MySQL relational database / data modeling -> `../relational-database-mcp-cloudbase/SKILL.md` or `../data-model-creation/SKILL.md`
• Cloud storage -> `../cloud-storage-web/SKILL.md`

Do NOT use for

• Direct implementation of web pages, auth flows, functions, or database operations when a more specific skill already fits.
• Low-level API parameter references or SDK recipes that belong in specialized skills.

Common mistakes / gotchas

• Treating this general skill as the default entry point for all CloudBase development.
• Staying here after the correct implementation skill is already clear.
• Mixing platform overview with platform-specific API shapes or SDK details.
• Using this overview skill as a detour in an existing application where the active auth, storage, and data files are already obvious.
• Making code or configuration changes without first following the Change Safety Protocol (`cloudbase-platform/references/protocols/change-safety-protocol.md`).
• Starting any deployment, publish, custom domain, or CloudRun work without first completing the checks in `cloudbase-platform/references/protocols/deployment-gate.md`.
• Echoing `x-cloudbase-context`, full `req.headers`, or `process.env` from Cloud Functions / CloudRun (including httpbin-style debug images) — follow `references/protocols/sensitive-runtime-data-protection.md`.
• **Confusing security domains with custom domains**: these are two different tools for different purposes. See the "Domain Management Tools" table below for the authoritative split.

When to use this skill

Use this skill for **CloudBase platform knowledge** when you need to:

• Understand CloudBase storage and hosting concepts
• Compare platform capabilities before implementation
• Understand cross-platform auth differences (Web vs Mini Program)
• Understand database permissions and access control
• Access CloudBase console management pages

**This skill provides foundational knowledge** that applies to all CloudBase projects, regardless of whether they are Web, Mini Program, or backend services.

How to use this skill (for a coding agent)

1. **Understand platform differences**

• Web and Mini Program have completely different authentication approaches
• Must strictly distinguish between platforms
• Never mix authentication methods across platforms
• If the workspace is already an application with TODOs or prebuilt handlers, do not stay in platform overview mode. Move quickly to the concrete implementation skill and the existing files that own the flow.

2. **Follow best practices**

• Use SDK built-in authentication features (Web)
• Understand natural login-free feature (Mini Program)
• Configure appropriate database permissions
• Prefer `@cloudbase/js-sdk` direct DB access for browser CRUD; use cloud functions only for secrets
