Usage Guidance
This skill is coherent for HeyGen TTS usage. Before installing, ensure you trust the skill source and are comfortable providing HEYGEN_API_KEY to it (the key allows calls to your HeyGen account). Limit exposure by using a scoped or expendable API key if HeyGen supports it, rotate keys regularly, and monitor HeyGen account activity for unexpected requests.
Capability Analysis
Type: OpenClaw Skill
Name: text-to-speech-heygen
Version: 2.23.0
The skill bundle provides standard instructions and code snippets for integrating with the HeyGen Starfish Text-to-Speech API. It correctly identifies the need for the HEYGEN_API_KEY environment variable and uses legitimate endpoints (api.heygen.com). There is no evidence of data exfiltration, malicious execution, or prompt injection attempts in SKILL.md.
Capability Assessment
Purpose & Capability
Name/description match the declared requirement (HEYGEN_API_KEY) and the SKILL.md shows only HeyGen TTS API endpoints and MCP tool calls; no unrelated services, binaries, or config paths are requested.
Instruction Scope
SKILL.md contains only instructions to call HeyGen's /v3/voices and /v3/voices/speech endpoints (or preferrable MCP tools). It does not instruct reading local files, other env vars, or sending data to unexpected endpoints.
Install Mechanism
No install spec and no code files (instruction-only). Nothing is downloaded or written to disk by the skill itself.
Credentials
Requires a single credential (HEYGEN_API_KEY) which is appropriate for accessing the HeyGen API; no additional secrets or unrelated env vars are requested.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request persistent system presence or modify other skills/configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install text-to-speech-heygen - After installation, invoke the skill by name or use
/text-to-speech-heygen - Provide required inputs per the skill's parameter spec and get structured output
