What is UCloud US3 Storage Skill?
The UCloud US3 Storage skill is designed to provide AI agents with a direct interface to UCloud's object storage infrastructure. By leveraging this skill within the Openclaw Skills ecosystem, developers can automate the lifecycle of digital assets, moving them from local environments to the cloud with minimal configuration. It handles the complexities of API authentication and content-type detection, making it an essential bridge for cloud-native workflows.
This skill is particularly valuable for scenarios where local data needs to be transformed into persistent, web-accessible resources. Whether you are dealing with automated reports, media assets, or system logs, this integration ensures your Openclaw Skills can store and share data reliably across the globe.

- Automating the archival of processed files after FFmpeg or OCR operations.
- Managing cloud asset organization using custom key paths and automated batch uploads.
How UCloud US3 Storage Skill Works
- The skill authenticates with the UCloud US3 API using provided public and private keys.
- It identifies the local file specified in the command arguments and validates its existence.
