OpenClaw OSS Artifact

Use this skill after creating a file, directory, or set of files that the user needs to download from an OSS signed URL.

Requirements

Credentials and defaults come from environment variables:

• OSS_ACCESS_KEY_ID (required)
• OSS_ACCESS_KEY_SECRET (required)
• OSS_BUCKET (required)
• OSS_ENDPOINT (required, for example https://oss-cn-hangzhou.aliyuncs.com)
• OSS_STS_TOKEN (optional, for temporary credentials)
• OSS_PREFIX (optional, object key prefix; default openclaw-artifacts)
• OSS_EXPIRES (optional, signed URL lifetime in seconds; default 3600)
• OSS_PUBLIC_ENDPOINT (optional, endpoint used in the returned URL if it differs from upload endpoint)
• OSS_IS_CNAME (optional, set to 1 when the endpoint is a custom OSS CNAME)

The access key must have permission to put objects into the configured bucket and read them through signed URLs. The uploader uses the Alibaba Cloud oss2 Python SDK. If it is not installed, install it with python3 -m pip install oss2.

Workflow

1. Finish generating the artifact locally.
2. Confirm the local artifact path exists.
3. Run the bundled uploader:

python3 skills/openclaw-oss-skills/scripts/upload_to_oss.py /absolute/path/to/artifact

For multiple files or a directory, pass each path. The script automatically creates a zip archive before upload:

python3 skills/openclaw-oss-skills/scripts/upload_to_oss.py /path/to/file-a.pdf /path/to/output-dir

If the skill folder is the current directory, run the script directly:

python3 scripts/upload_to_oss.py /absolute/path/to/artifact

1. Return the download_url shown by the script to the user as a Markdown link. Mention the expiration time if the user may need to know it.

Options

• --object-key <key>: upload with an explicit OSS object key. Use only for a single file.
• --prefix <prefix>: override OSS_PREFIX.
• --bucket <bucket>: override OSS_BUCKET.
• --endpoint <endpoint>: override OSS_ENDPOINT.
• --public-endpoint <endpoint>: override OSS_PUBLIC_ENDPOINT.
• --expires <seconds>: override OSS_EXPIRES.
• --json: print machine-readable JSON only.

Output Contract

The script prints:

• object_key: object path inside the bucket
• download_url: signed URL for direct download
• expires_at: ISO-8601 UTC expiration time
• source: uploaded local file or temporary zip path

In the final answer, include the signed link and keep the local path available for debugging if upload fails.
