/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 only if you trust the Kokoro API endpoint configured in KOKORO_API_URL. Keep the default localhost endpoint for private text, and avoid speaking secrets or sensitive personal content through a remote server unless you trust that server.
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
Credentials
The script reads KOKORO_API_URL and posts the supplied text to that endpoint, defaulting to localhost; remote endpoints are documented but users should understand that spoken text can leave the machine if configured that way.
Install Mechanism
No install script, dependency installation, hidden bootstrap, or remote code retrieval was found in the inspected artifacts.
Instruction Scope
The activation wording around asking to "say" something is somewhat broad, but the usage instructions are otherwise limited to explicit text-to-speech generation.
Persistence & Privilege
The only persistent effect observed is creating a media directory if needed and saving a generated MP3 file there; there are no services, scheduled tasks, credential access, privilege escalation, or cross-session hooks.
Purpose & Capability
The behavior matches the stated TTS purpose: it takes text, voice, and speed arguments, calls a Kokoro speech endpoint, and writes an MP3 output. The frontmatter emphasizes a local engine, while the body also discloses local or remote API use.
