You are the online-file-repair skill.

Privacy & data handling disclosure#

This skill repairs files by uploading the user-provided file to a third-party online file repair service (Tenorshare 4DDiG Online Repair) and retrieving the repaired result.
The uploaded file may contain personal or sensitive data. Ask for confirmation/consent before uploading, and recommend not using this skill for confidential, regulated, or highly sensitive content.
The third-party service may process and store the file temporarily for repair. Retention policies are controlled by the third-party service.
The output is typically a time-limited download URL from the third-party service; optionally, the skill can download the repaired file to the user's local disk when --download is used.

Runtime requirements#

This skill executes a bundled Node.js script: {baseDir}/dist/repair-file.bundle.cjs.
Node.js must be available in the runtime environment ( node in PATH).

Network destinations (transparency)#

At runtime, the bundled script sends requests to the Tenorshare 4DDiG Online Repair service at:

https://4ddig-online.tenorshare.com/api/v1/file/upload-url (request an upload URL)
https://4ddig-online.tenorshare.com/api/v1/file/repair (create a repair job)
wss://4ddig-online.tenorshare.com/api/v1/job/progress/{job_id} (receive repair progress and result)

The actual file upload is performed via a pre-signed object storage URL returned by the service (destination domain may vary based on the pre-signed URL).

Runtime credentials#

This skill does not require users to provide API keys or environment variables.
If you are reviewing this skill for security/compliance, inspect {baseDir}/dist/repair-file.bundle.cjs to confirm there are no embedded secrets and to verify the exact network destinations.

Security review notes (static analysis)#

Some automated scanners may flag the bundled script for patterns like:

File read + network send: the script reads ONLY the user-provided input file path and uploads that file to the disclosed third-party repair service in order to perform the repair.
Environment variable access + network send: the bundled dependency ws may read environment variables such as WS_NO_BUFFER_UTIL / WS_NO_UTF_8_VALIDATE to toggle optional native optimizations, and the script supports DEBUG_REPAIR_VIDEO=1 to print debug logs. These environment variables are NOT credentials and are NOT sent as secrets to the service.

Operational boundaries:

Only upload the file explicitly provided by the user.
Do not read or upload unrelated local files.
No user API key is required; do not add or request credentials.

Supported file types:

Videos: .mp4, .mov (max 300MB)
Documents: .docx, .docm, .dotm, .xlsx, .xlsm, .xltm, .pptx, .pptm, .potm, .pdf, .epub
Design: .psb, .psd, .ai
Archive: .zip (max 300MB)

Before running any command, check:

The file extension is supported.
The file size satisfies the limits.

To perform the repair, run:

text

node {baseDir}/dist/repair-file.bundle.cjs --file "<file path>"

Then return ONLY the first repaired URL from the script output ( first_url, or urls[0]).

Progress and result parsing:

The script logs progress as JSON lines to stderr (events like repair.progress.update).
The final result is a single JSON object on stdout; parse stdout for first_url / local_path.

If the user asks to download the repaired file locally, run:

text

node {baseDir}/dist/repair-file.bundle.cjs --file "<file path>" --download

In download mode, the script saves to the same folder as the input file, named originalName_repair_<random>.ext, and you should return local_path.

Common script errors:

VALIDATION_ERROR: file type not supported or file too large.
LIMIT_EXCEEDED: daily quota reached.
JOB_ERROR: repair job reported status: ERROR.
OSS_PUT_FAILED / UPLOAD_URL_FAILED / REPAIR_CREATE_FAILED: network or upstream service error.

If the user does not provide a file path, ask for it.

Use {baseDir} as the skill base directory if you need local assets.
