Edge TTS English
Generate native-quality English audio using Microsoft Edge TTS (/root/.local/bin/edge-tts).
Workflow
- Run
scripts/speak.sh "\x3Ctext>" [voice] [output_path] - Send the resulting MP3 to the user via
messagetool withmedia=\x3Coutput_path>
bash scripts/speak.sh "Hello, world!" en-US-AriaNeural /tmp/tts_out.mp3

Notes
- Scripts path: resolve relative to this skill's directory
- edge-tts binary:
/root/.local/bin/edge-tts - Default output:
/tmp/edge_tts_output.mp3 - Always send audio via
messagetool (mediaparam), not as text
Usage Guidance
This skill appears to do what it says: call the edge-tts client to produce MP3 audio and return it. Before installing, verify that you are willing to (a) let the agent run a local binary at /root/.local/bin/edge-tts (or change the path to where you installed it), and (b) allow edge-tts to communicate with Microsoft services — any text you send for TTS may be transmitted to Microsoft endpoints by that client. Because the registry entry includes no install step, consider installing edge-tts yourself (pipx) and confirming the binary path. If you need stricter guarantees, ask the author to add an explicit install spec, or inspect/replace the script to run a vetted TTS binary. Finally, ensure sensitive text is not sent to TTS if you do not want it shared with external services.
Capability Analysis
Type: OpenClaw Skill
Name: edge-tts-english
Version: 1.0.2
The `scripts/speak.sh` file is vulnerable to shell injection. The `$TEXT`, `$VOICE`, and `$OUTPUT` arguments are directly interpolated into the `edge-tts` command without explicit sanitization. If the OpenClaw agent passes unsanitized user input to this script, an attacker could inject arbitrary shell commands (e.g., `'; rm -rf / #'`) leading to remote code execution. This is a critical vulnerability, but not evidence of intentional malicious design within the skill itself.
Capability Assessment
Purpose & Capability
Name/description (Edge TTS English) match the included script and SKILL.md. The script invokes /root/.local/bin/edge-tts to produce MP3 output — this is exactly what the skill claims to do.
Instruction Scope
SKILL.md instructs running scripts/speak.sh with text, voice, and output path then sending the MP3 via the platform message tool. The script only passes those arguments to edge-tts and writes an output file; it does not read unrelated files, environment variables, or endpoints itself.
Install Mechanism
There is no formal install spec in the registry (instruction-only), but SKILL.md states edge-tts must be installed via pipx and references /root/.local/bin/edge-tts. That mismatch is not dangerous but means the skill will fail (or behave unexpectedly) if the binary is absent or at a different path. No third-party downloads or unknown URLs are present in the skill itself.
Credentials
The skill does not request environment variables, credentials, or config paths. This is proportionate for a simple TTS wrapper. Note: the edge-tts client it relies on may perform network calls to Microsoft services; that external behavior is not controlled by the skill's declared requirements.
Persistence & Privilege
Skill is not always-enabled and uses default model invocation behavior. It does not attempt to modify other skills or system-wide configs and only writes its own output file (default /tmp/edge_tts_output.mp3).
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install edge-tts-english - After installation, invoke the skill by name or use
/edge-tts-english - Provide required inputs per the skill's parameter spec and get structured output
