## Description

Complete guide for CloudBase cloud storage using Web SDK (@cloudbase/js-sdk) - upload, download, temporary URLs, file management, and best practices.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

## 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.

# Cloud Storage Web SDK

## Activation Contract

### Use this first when

- A browser or Web app must upload, download, or manage CloudBase storage objects through `@cloudbase/js-sdk`.
- The request mentions `uploadFile`, `getTempFileURL`, `deleteFile`, or `downloadFile` in frontend code.

### Read before writing code if

- The task is browser-side storage work but you still need to separate it from Mini Program storage, backend storage management, or static hosting deployment.
- The request may be blocked by security domains or frontend auth.

### Then also read

- Web login and identity -> `../auth-web-cloudbase/SKILL.md`
- General Web app setup -> `../web-development/SKILL.md`
- Direct storage management through MCP tools -> `../cloudbase-platform/SKILL.md`

### Do NOT use for

- Mini Program file APIs.
- Backend or agent-side direct storage management through MCP.
- Static website hosting deployment via `manageHosting(action="upload")`.
- Database operations.
