What problem does it solve? When working with WeCom (Enterprise WeChat) workflows, media files are referenced by opaque media_id values that cannot be used directly as local files. This Skill bridges that gap by downloading media_id-referenced files to local paths and uploading local files to obtain media_id values for use by other business skills like email and WeDrive. ## Core Features & Use Cases - Media Download: Download any media file to a local file path by providing its media_id, returned by other skills such as email attachments or embedded images. - Media Upload: Upload a local file to obtain a media_id, media type, and creation timestamp for downstream use, such as supplying file_content_media to WeDrive uploads. - Use Case: An email skill returns a media_id for an attachment. Use this Skill to download it to a local file_path, then read the file content directly from that path. ## Quick Start Ask the assistant to download the WeCom media file with a given media_id to a local path, or upload a local file to get its media_id.
