nano---Openclaw: Skill for Claude Code

Add Voice Transcription

This skill adds automatic voice message transcription to NanoClaw's WhatsApp channel using OpenAI's Whisper API. When a voice note arrives, it is downloaded, transcribed, and delivered to the agent as [Voice: <transcript>].

Phase 1: Pre-flight

Check if already applied

Check if src/transcription.ts exists. If it does, skip to Phase 3 (Configure). The code changes are already in place.

Ask the user

Use AskUserQuestion to collect information:

AskUserQuestion: Do you have an OpenAI API key for Whisper transcription?

If yes, collect it now. If no, direct them to create one at https://platform.openai.com/api-keys.

Phase 2: Apply Code Changes

Prerequisite: WhatsApp must be installed first (skill/whatsapp merged). This skill modifies WhatsApp channel files.

Ensure WhatsApp fork remote

git remote -v

If whatsapp is missing, add it:

git remote add whatsapp https://github.com/qwibitai/nanoclaw-whatsapp.git

Merge the skill branch

git fetch whatsapp skill/voice-transcription
git merge whatsapp/skill/voice-transcription || {
  git checkout --theirs package-lock.json
  git add package-lock.json
  git merge --continue
}

This merges in:

• src/transcription.ts (voice transcription module using OpenAI Whisper)
• Voice handling in src/channels/whatsapp.ts (isVoiceMessage check, transcribeAudioMessage call)
• Transcription tests in src/channels/whatsapp.test.ts
• openai npm dependency in package.json
• OPENAI_API_KEY in .env.example

If the merge reports conflicts, resolve them by reading the conflicted files and understanding the intent of both sides.

Validate code changes

npm install --legacy-peer-deps
npm run build
npx vitest run src/channels/whatsapp.test.ts

All tests must pass and build must be clean before proceeding.

Phase 3: Configure

Get OpenAI API key (if needed)

If the user doesn't have an API key:

I need you to create an OpenAI API key:

1. Go to https://platform.openai.com/api-keys
2. Click "Create new secret key"
3. Give it a name (e.g., "NanoClaw Transcription")
4. Copy the key (starts with sk-)

Cost: $0.006 per minute of audio ($0.003 per typical 30-second voice note)
