Pronunciation Coach

Security checks across malware telemetry and agentic risk

Overview

This appears to be a legitimate pronunciation coach, but it deserves review because it sends voice recordings to SenseAudio, stores detailed progress locally, and uses shell examples that can mishandle user-supplied practice text.

Install only if you are comfortable using a SenseAudio API key and sending practice text and voice recordings to SenseAudio. Use non-sensitive phrases, run it in a private folder, delete pronunciation_progress.json when no longer needed, and have the agent build request JSON safely instead of pasting raw user text into shell commands.

Context-Inappropriate Capability

Low
Confidence
90% confidence
Finding
The skill instructs saving detailed pronunciation session history, including practice text, accuracy, and error patterns, to a local file. While useful for coaching, this creates persistent user profiling without any explicit consent, retention limit, or access control guidance, which increases privacy risk if the host environment is shared, synced, or later inspected.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill directs the agent to save user practice data locally without warning the user or requesting consent. Because the stored data includes behavioral performance information across sessions, this can silently create a longitudinal record of the user's speech practice and weaknesses, which is a privacy issue beyond the immediate session purpose.

External Transmission

When the user uploads their recording:

```bash
curl -s -X POST https://api.senseaudio.cn/v1/audio/transcriptions \
  -H "Authorization: Bearer $SENSEAUDIO_API_KEY" \
  -F "file=@<USER_RECORDING>" \
  -F "model=sense-asr-pro" \
