What problem does it solve? Local images cannot be referenced in WeChat article previews or public web pages. This Skill uploads local image files to a configured Upyun S3-compatible bucket and returns a public HTTPS URL and object key, so images become accessible online without manual console operations. ## Core Features & Use Cases - Authorized external upload: Runs only after the user explicitly requests an upload, public image, or copy-page preview; credentials are injected by the workbench tool runtime and never read from .env files or echoed in logs. - Structured JSON output: Returns {"success":true,"data":{"url":"https://...","key":"..."}} on success and a credential-free error message on failure, so callers can safely update documents only on verified success. - Batch-safe behavior: Uploads images one by one, records the local-path-to-URL mapping, keeps original references on failure, and never deletes local files afterward. - Use Case: While typesetting a WeChat article, you need a local cover image to be publicly accessible for preview. Invoke the upload, receive the HTTPS URL, and insert it into the article HTML. ## Quick Start Ask the assistant to upload a specific local image file to the configured Upyun storage and return its public HTTPS URL.
