安全使用建议
This skill appears to do exactly what it claims: run the included Python script which opens a WebSocket to UniSound's TTS service and saves audio to results/. Before installing/running: (1) verify you trust the UNISOUND_APPKEY/UNISOUND_SECRET you supply (do not use credentials you don't control), (2) inspect scripts/tts.py (it is short and readable) if you have privacy concerns about sending text to an external API, and (3) be aware the script will open outbound network connections to wss://ws-stts.hivoice.cn and write files to a local results/ folder. Also note the README contains example/demo credentials—do not reuse those for production.
功能分析
Type: OpenClaw Skill
Name: u2-tts
Version: 1.0.5
The u2-tts skill is a legitimate implementation of a text-to-speech client for the UniSound WebSocket API. The core logic in `scripts/tts.py` handles authentication via SHA256 signatures and manages binary audio streams as expected for this service. While `SKILL.md` contains highly restrictive instructions for the AI agent (e.g., 'MANDATORY RESTRICTIONS' forbidding fallback methods) and provides hardcoded test credentials, these are accompanied by explicit security warnings regarding data privacy and the intended use of test keys. No evidence of malicious data exfiltration, unauthorized execution, or obfuscation was found.
能力评估
Purpose & Capability
The name/description, required env vars (UNISOUND_APPKEY, UNISOUND_SECRET), required binary (python), and included script all align with a UniSound TTS client. There are no unrelated credentials or binaries requested.
Instruction Scope
SKILL.md instructs the agent to only run the included Python script and not to perform local synthesis or fallbacks. That is restrictive but consistent with a remote-API-only design. SKILL.md also contains example/demo credentials embedded in the docs—these are likely test keys and should not be treated as production secrets.
Install Mechanism
This is an instruction-only skill with a bundled Python script and a requirements.txt. No external arbitrary downloads or install hooks are present. Dependencies are standard (websocket-client, optional gevent).
Credentials
Only two env vars are required (appkey and secret), which matches the TTS API's needs. The script reads only those env vars (and respects CLI overrides). The primary credential is the UNISOUND_SECRET as declared.
Persistence & Privilege
always is false and the skill does not request elevated or persistent system privileges. It writes output files to a local results/ directory and has a .claude settings file granting Bash/python execution permissions (expected for running the script). It does not modify other skills or system configs.
