audio-transcribe

audio-transcribe is a skill for Claude Code, Codex from AtomicBot-ai/atomic-agent. It costs 58 tokens per session (803 once invoked), scanned A, original, MIT.

A local command-line tool that turns spoken audio files into written text. It supports common formats such as MP3, M4A, WAV, OGG, FLAC, and WebM, without an API key.

In plain words
What is it for?
Use it to transcribe meetings, interviews, voice notes, or other audio when the spoken content is needed for an answer or task.
Why use it?
It lets an agent work from an audio attachment by converting speech into a readable transcript instead of relying on the chat model to hear the recording.

About the project

Atomic Agent is a local-first AI agent that runs its control loop and state on a user's machine while using local or cloud models. It drives browsers, edits files, runs approved commands, remembers context, schedules follow-ups, and connects to external tools, with the catalogue providing skills for its use.

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

audio-transcribe 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

audio-transcribe

Turn spoken audio into text locally with whisper. Whisper writes a plain-text transcript next to the audio; you then read that file and answer from its content. The chat model never "hears" the audio — whisper does the listening as a separate process, so this works regardless of model size.

Setup health check (run first, every session)

Verify with one solo step:

[{ "tool": "os.shell.run", "args": { "cmd": "whisper", "args": ["--help"] } }]

Outcome map:

  • exit 0 + usage text → ready, proceed.
  • command not found: whisper → enter Setup playbook → "whisper missing".

Setup playbook (when prerequisites are missing)

whisper missing

Reply (solo reply step):

"whisper is not installed. I can install it: brew install openai-whisper (also needs ffmpeg). Install it?"

On yes:

[{ "tool": "os.shell.run", "args": { "cmd": "brew", "args": ["install", "openai-whisper", "ffmpeg"] } }]

On Linux: pipx install openai-whisper (or pip install openai-whisper) plus apt-get install ffmpeg. The first transcription downloads the model weights to ~/.cache/whisper.

When to use

  • The task references an audio attachment (.mp3, .m4a, .wav, .ogg, .flac, .webm) and the answer depends on what is said in it.
  • "What does the speaker say…", "list the ingredients mentioned…", "which page numbers are read aloud…".

When NOT to use

  • The audio only needs format conversion / trimming — that's the ffmpeg skill.
  • The attachment is an image / document — use vision or fs.read_document.

How to transcribe

  1. Transcribe to a .txt next to the audio (one solo step). Pick the model by need: small is a good speed/accuracy default; use medium when accuracy matters and the clip is short.
[{ "tool": "os.shell.run", "args": { "cmd": "whisper", "args": ["audio.mp3", "--model", "small", "--output_format", "txt", "--output_dir", ".", "--language", "en"] } }]

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.
