ghostclaw: Skill for Claude Code

.claude/skills/add-voice-reply/SKILL.md

add-voice-reply is a skill for Claude Code from b1rdmania/ghostclaw. It costs 22 tokens per session (417 once invoked), scanned A, original, MIT.

An add-on that makes a bot answer voice notes with voice notes, using ElevenLabs text-to-speech to produce the audio.

In plain words
What is it for?
Use it to configure an ElevenLabs API key and voice, rebuild the bot, and test voice-note replies. It supports selecting a library voice or providing a custom voice ID.
Why use it?
It lets voice-message conversations stay in an audio format rather than switching from a spoken message to a written reply. Text messages continue to receive text replies.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-voice-reply scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Add Voice Replies (ElevenLabs)

When someone sends a voice note, the bot replies with a voice note instead of text. Uses ElevenLabs TTS.

Setup

1. ElevenLabs API key

Ask the user to:

  1. Sign up at elevenlabs.io
  2. Go to Settings > API Keys
  3. Copy the API key

Add to .env:

ELEVENLABS_API_KEY=<key>

2. Pick a voice

Ask: "Which voice should the bot use? You can browse voices at elevenlabs.io/voice-library, or use a custom/cloned voice."

If they have a specific voice, get the voice ID from the ElevenLabs dashboard. If not, suggest they browse the library and pick one that fits.

Add to .env:

ELEVENLABS_VOICE_ID=<voice_id>

If they skip this, the default voice will be used.

3. Rebuild and restart

npm run build
launchctl kickstart -k gui/$(id -u)/com.ghostclaw  # macOS
# systemctl --user restart ghostclaw                # Linux

4. Test

Tell the user to send a voice note to the bot. It should reply with a voice note using the selected voice. Text messages still get text replies.

How it works

The bot detects when an incoming message is a voice note (tagged [Voice: ...] after transcription). When replying to a voice message, it converts the text response to audio via ElevenLabs TTS and sends it as a voice note. Text messages always get text replies.

Disabling

Remove ELEVENLABS_API_KEY from .env and restart. The bot will fall back to text replies for everything.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
