Speech-to-text transcription via OpenAI Whisper. An agent skill from coco-research/coco.

  • The user needs to transcribe audio files
  • SKILL.md covers Mode 1: Local CLI, Mode 2: Cloud API and Choosing Between Modes
  • Calls whisper and curl; reaches api.openai.com; needs OPENAI_API_KEY
  • Translate speech

What it does

Openai Whisper is an agent skill from coco-research/coco. Speech-to-text transcription via OpenAI Whisper. Supports two modes — Local CLI (no API key, runs on-device) and Cloud API (fast, scalable, requires OPENAIAPIKEY). Use when the user needs to transcribe audio files, translate speech, or convert audio to text.

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Transcription, Speech recognition and synthesis and LLM API integration. It works with Whisper and OpenAI. The repository describes itself as: CoCo Super Intelligence is the orchestration layer that turns Claude Code, Cursor, or Codex into an engineering department: a routed advisory board, 226 skills, 386 commands…

When your agent uses it

  • The user needs to transcribe audio files
  • Translate speech
  • Convert audio to text

Example prompts

  • “/openai-whisper”

Requirements

  • A credential in OPENAI_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 1a642ae. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • whisper
    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.openai.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Openai Whisper loads about 964 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 244 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~964

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 244 words (~964 tokens).
