labor.fun: Skill for Claude Code

.claude/skills/use-local-whisper/SKILL.md

use-local-whisper is a skill for Claude Code from BreadchainCoop/labor.fun. It costs 46 tokens per session (1,289 once invoked), scanned A, a copy of use-local-whisper, MIT.

A setup skill that changes WhatsApp voice transcription from OpenAI’s Whisper service to whisper.cpp running on an Apple Silicon Mac. The audio is transcribed on the device instead of being sent to an online API.

In plain words
What is it for?
Use it to configure local WhatsApp voice transcription when the voice-transcription skill is already installed, whisper.cpp and ffmpeg are available, and a compatible model is stored locally.
Why use it?
It removes the need for an API key, network access, and per-use transcription costs, while keeping audio processing local.

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

use-local-whisper 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use Local Whisper

Switches voice transcription from OpenAI's Whisper API to local whisper.cpp. Runs entirely on-device — no API key, no network, no cost.

Channel support: Currently WhatsApp only. The transcription module (src/transcription.ts) uses Baileys types for audio download. Other channels (Telegram, Discord, etc.) would need their own audio-download logic before this skill can serve them.

Note: The Homebrew package is whisper-cpp, but the CLI binary it installs is whisper-cli.

Prerequisites

  • voice-transcription skill must be applied first (WhatsApp channel)
  • macOS with Apple Silicon (M1+) recommended
  • whisper-cpp installed: brew install whisper-cpp (provides the whisper-cli binary)
  • ffmpeg installed: brew install ffmpeg
  • A GGML model file downloaded to data/models/

Phase 1: Pre-flight

Check if already applied

Check if src/transcription.ts already uses whisper-cli:

grep 'whisper-cli' src/transcription.ts && echo "Already applied" || echo "Not applied"

If already applied, skip to Phase 3 (Verify).

Check dependencies are installed

whisper-cli --help >/dev/null 2>&1 && echo "WHISPER_OK" || echo "WHISPER_MISSING"
ffmpeg -version >/dev/null 2>&1 && echo "FFMPEG_OK" || echo "FFMPEG_MISSING"

If missing, install via Homebrew:

brew install whisper-cpp ffmpeg

Check for model file

ls data/models/ggml-*.bin 2>/dev/null || echo "NO_MODEL"

If no model exists, download the base model (148MB, good balance of speed and accuracy):

mkdir -p data/models
curl -L -o data/models/ggml-base.bin "https://huggingface.co/ggerganov/whisper.cpp/resolve/main/ggml-base.bin"

For better accuracy at the cost of speed, use ggml-small.bin (466MB) or ggml-medium.bin (1.5GB).

Phase 2: Apply Code Changes

Ensure WhatsApp fork remote

git remote -v

If whatsapp is missing, add it:

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

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.
