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:

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:

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.
