## What it does

This skill transcribes audio files locally using `coli asr` with zero cloud API dependencies. By default, it runs the `sensevoice` model, which handles Chinese, English, Japanese, Korean, and Cantonese while detecting audio events and tone. For English-only workflows, you can switch the configuration to `whisper-tiny.en`.

The workflow is guided: the skill validates the environment, asks for the audio path if missing, requests confirmation, and runs the CLI tool. When the `polish` option is active, Claude cleans up punctuation and removes filler words without summarizing the original speech. The final text appears directly in the conversation, with an optional step to save a Markdown file in your current working directory.

Execution blocks immediately if the `@marswave/coli` package is missing from your global npm tools. You also need `ffmpeg` for compressed audio containers, though uncompressed WAV files work without it. On the first run, the tool downloads roughly 60MB of model weights into `~/.coli/models/`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add marswaveai/skills --skill asr -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/asr/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/asr/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add marswaveai/skills --skill asr -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/asr/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add marswaveai/skills --skill asr -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/asr/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install marswaveai/skills asr
```

2. **Manually: put the files in place**
- File: `.github/skills/asr/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add marswaveai/skills --skill asr -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/marswaveai/skills --path asr
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/asr/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add marswaveai/skills --skill asr -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/marswaveai/skills/tree/HEAD/asr/SKILL.md

## When to use it
- transcribe local audio recordings without third-party cloud APIs
- clean up filler words and punctuation in raw speech transcripts
- export meeting transcriptions to Markdown files with metadata

## Example prompts
- transcribe meeting.m4a
- transcribe interview.wav, no polish
- transcribe this recording and save the transcript to markdown

  Transcribe audio files to text using local speech recognition. Triggers on:
  "转录", "transcribe", "语音转文字", "ASR", "识别音频", "把这段音频转成文字".
---

## When to Use

- User wants to transcribe an audio file to text
- User provides an audio file path and asks for transcription
- User says "转录", "识别", "transcribe", "语音转文字"

## When NOT to Use

- User wants to synthesize speech from text (use `/tts`)
- User wants to create a podcast or explainer (use `/podcast` or `/explainer`)

## Purpose

Transcribe audio files to text using `coli asr`, which runs fully offline via local
speech recognition models. No API key required. Supports Chinese, English, Japanese,
Korean, and Cantonese (sensevoice model) or English-only (whisper model).

Run `coli asr --help` for current CLI options and supported flags.

## Hard Constraints

- No shell scripts. Use direct commands only.
- Always read config following `shared/config-pattern.md` before any interaction
- Follow `shared/cli-patterns.md` for interaction patterns
- Never ask more than one question at a time

<HARD-GATE>
Use the AskUserQuestion tool for every multiple-choice step — do NOT print options as
plain text. Ask one question at a time. Wait for the user's answer before proceeding.
After all parameters are collected, summarize and ask the user to confirm before
running any transcription.

</HARD-GATE>

## Interaction Flow

### Step 0: Prerequisites Check

Before config setup, silently check the environment:

```bash
COLI_OK=$(which coli 2>/dev/null && echo yes || echo no)
FFMPEG_OK=$(which ffmpeg 2>/dev/null && echo yes || echo no)
MODELS_DIR="$HOME/.coli/models"
MODELS_OK=$([ -d "$MODELS_DIR" ] && ls "$MODELS_DIR" | grep -q sherpa && echo yes || echo no)
```

| Issue | Action |
|-------|--------|
| `coli` not found | Block. Tell user to run `npm install -g @marswave/coli` first |
| `ffmpeg` not found | Warn (WAV files still work). Suggest `brew install ffmpeg` / `sudo apt install ffmpeg` |
| Models not downloaded | Inform user: first transcription will auto-download models (~60MB) to `~/.coli/models/` |

If `coli` is missing, stop here and do not proceed.

### Step 0: Config Setup

Follow `shared/config-pattern.md` Step 0 (Zero-Question Boot).

**If file doesn't exist** — silently create with defaults and proceed:
```bash
mkdir -p ".listenhub/asr"
echo '{"model":"sensevoice","polish":true}' > ".listenhub/asr/config.json"
CONFIG_PATH=".listenhub/asr/config.json"
CONFIG=$(cat "$CONFIG_PATH")
```
**Do NOT ask any setup questions.** Proceed directly to the Interaction Flow with sensible defaults (sensevoice model, polish enabled).

**If file exists** — read config silently and proceed:
```bash
CONFIG_PATH=".listenhub/asr/config.json"
[ ! -f "$CONFIG_PATH" ] && CONFIG_PATH="$HOME/.listenhub/asr/config.json"
CONFIG=$(cat "$CONFIG_PATH")
```

### Setup Flow (user-initiated reconfigure only)

Only run when the user explicitly asks to reconfigure. Display current settings:
````
