/install kokoro-tts
Description
Generate spoken audio from text using the local Kokoro TTS engine. Use when the user asks to "say" something, requests a voice message, or wants text converted to speech.
Usage Guidance
Install this if you trust the Kokoro endpoint you will use. Prefer the localhost default, avoid sending secrets or sensitive private text to an untrusted remote server, and expect generated audio files to accumulate in the local media directory.
Capability Analysis
Type: OpenClaw Skill
Name: kokoro-tts
Version: 0.1.0
The skill is designed to generate speech using a configurable Kokoro TTS API. It makes a network POST request to the API_URL (defaulting to localhost) with user-provided text, voice, and speed, then saves the resulting audio to a local 'media' directory. There is no evidence of prompt injection in SKILL.md, malicious execution (user input is JSON-encoded, not executed), data exfiltration beyond sending the requested text to the configured TTS endpoint, or persistence mechanisms. All file and network operations are directly aligned with the stated purpose of a text-to-speech skill.
Capability Assessment
Purpose & Capability
The stated purpose, instructions, and script behavior align: it takes text, optional voice and speed settings, posts them to a Kokoro TTS endpoint, and writes a generated MP3.
Instruction Scope
The trigger wording includes broad requests to "say" something, which could be ambiguous in an agent, but the documented action is still limited to user-requested speech generation and contains no hidden control instructions.
Install Mechanism
The skill has no installer or package mutation behavior, but it assumes Node.js and uses an optional KOKORO_API_URL environment variable that are documented in SKILL.md rather than explicit install metadata.
Credentials
Network transfer of the input text is necessary for TTS and defaults to localhost; if the user configures a remote endpoint, the spoken text will be sent to that server.
Persistence & Privilege
The script creates a local media directory and writes timestamped MP3 outputs only; it does not request credentials, read local profiles, install persistence, or perform destructive actions.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install kokoro-tts - After installation, invoke the skill by name or use
/kokoro-tts - Provide required inputs per the skill's parameter spec and get structured output
