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.
