zorya: Skill for Claude Code

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

add-voice-transcription is a skill for Claude Code from mihaipora/zorya. It costs 38 tokens per session (1,064 once invoked), scanned A, a copy of add-voice-transcription, MIT.

A NanoClaw add-on that turns WhatsApp voice notes into text using OpenAI's Whisper speech-to-text service, so the agent can read them.

In plain words
What is it for?
It downloads incoming WhatsApp voice notes, transcribes them, and passes the text to NanoClaw as a message.
Why use it?
It removes the need to listen to voice messages before the agent can understand and answer them. An OpenAI API key is required.

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-transcription scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (add/src/transcription.ts, modify/src/channels/whatsapp.test.ts, modify/src/channels/whatsapp.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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

Read .nanoclaw/state.yaml. If voice-transcription is in applied_skills, 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

Run the skills engine to apply this skill's code package.

Initialize skills system (if needed)

If .nanoclaw/ directory doesn't exist yet:

npx tsx scripts/apply-skill.ts --init

Apply the skill

npx tsx scripts/apply-skill.ts .claude/skills/add-voice-transcription

This deterministically:

  • Adds src/transcription.ts (voice transcription module using OpenAI Whisper)
  • Three-way merges voice handling into src/channels/whatsapp.ts (isVoiceMessage check, transcribeAudioMessage call)
  • Three-way merges transcription tests into src/channels/whatsapp.test.ts (mock + 3 test cases)
  • Installs the openai npm dependency
  • Updates .env.example with OPENAI_API_KEY
  • Records the application in .nanoclaw/state.yaml

If the apply reports merge conflicts, read the intent files:

  • modify/src/channels/whatsapp.ts.intent.md — what changed and invariants for whatsapp.ts
  • modify/src/channels/whatsapp.test.ts.intent.md — what changed for whatsapp.test.ts

Validate code changes

npm test
npm run build

All tests must pass (including the 3 new voice transcription tests) 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:

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
