dy-caption

Security checks across malware telemetry and agentic risk

Overview

This skill transparently sends Douyin share content and a dy-caption API key to an external transcription service, which matches its stated purpose.

Install only if you trust dy-caption and api.dycaption.cn with the Douyin share text and your API key. Use a dedicated or revocable key if possible, avoid submitting private or sensitive videos, and verify the GitHub repository before cloning it.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The README explicitly states that user-provided share links/share text and the API key are sent to a third-party remote service, yet it does not disclose privacy, retention, logging, or handling expectations. This creates a real data exposure risk because users may submit sensitive content or credentials without informed consent, and agent operators may unknowingly route private data off-platform.
