## What it does

The skill reads the pet profile from the `companion` field in `~/.claude.json`, then derives a vocal identity from its name and personality. It stores that identity in `~/.claude/skills/buddy-sings/voices/<name>.json`, so later requests use the same voice. A changed personality or a request to change the voice creates a new version.

For songs about your day, work, or shared history, it checks the current conversation, memory files, and recent Git commits. It skips that collection for a standalone song idea. Lyrics default to the user's language.

Music generation requires `mmx CLI` and a MiniMax API key. Playback needs at least one player: `mpv`, `ffplay`, or `afplay`. Check the key and local player before relying on playback.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MiniMax-AI/skills --skill buddy-sings -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MiniMax-AI/skills --skill buddy-sings -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MiniMax-AI/skills --skill buddy-sings -a cursor
```

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

### GitHub Copilot

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MiniMax-AI/skills --path skills/buddy-sings
```

### Windsurf (Devin Desktop)

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

### OpenCode

```bash
npx skills add MiniMax-AI/skills --skill buddy-sings -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/MiniMax-AI/skills/tree/HEAD/skills/buddy-sings/SKILL.md

## When to use it
- turn a `/buddy` pet into a song performer
- keep a consistent voice for one pet
- write a song about recent project work
- regenerate a pet voice on request
- play generated music locally

## Example prompts
- Have my `/buddy` pet sing about the work I did today.

# Buddy Sings — Let Your Claude Code Pet Sing

Turn your Claude Code pet into a singer. Each pet gets a unique vocal identity
based on its name and personality — the same pet always sounds the same.

## Prerequisites

- **mmx CLI** (required for music generation):

  **Install:**
  ```bash
  npm install -g mmx-cli
  ```

  **Authenticate (first time only):**
  ```bash
  mmx auth login --api-key <your-minimax-api-key>
  ```
  Get your API key from [MiniMax Platform](https://platform.minimaxi.com/).

- **Audio player** (for playback — at least one of):
  - `mpv` (recommended — interactive controls: space = pause, q = quit)
  - `ffplay` (from FFmpeg)
  - `afplay` (macOS built-in)

---

## Workflow Overview

```
Check pet → Build vocal identity → Gather context → Generate music → Play & feedback
```

---

## Language & Interaction

Detect the user's language from their first message. Respond in the same language
throughout the entire session. All examples below are in English — translate them
naturally when responding in other languages.

**User-facing text localization rule**:
- ALL text shown to the user — including pet info, voice description, lyrics preview,
  prompt preview, playback info, and feedback prompts — MUST be fully translated into
  the user's language.
- The **API prompt** sent to the model should always be written in English for best
  generation quality. However, when previewing the prompt to the user, show a localized
  description in the user's language instead of the raw English prompt. The English prompt
  is an internal implementation detail — the user does not need to see it.
- The templates below are written in English as reference. At runtime, translate every
  label and message into the user's detected language.

The pet sings in the user's language by default. Embed the singing language
naturally in the vocal description (e.g., "singing in Japanese" or "singing in
Mandarin Chinese") rather than appending a separate language tag. If the user
explicitly requests a different language for the lyrics, honor that request.

---

## Step 1: Check for Pet

Read `~/.claude.json` and look for the `companion` field.

If no companion is found or the field is empty, tell the user:

```
You don't have a pet yet! Type /buddy to adopt one, then come back to let it sing.
```

Stop here and wait for the user to adopt a pet. Do not proceed without a pet.

If a companion exists, extract its profile:
- `name` — the pet's name
- `personality` — the pet's personality description

Present the pet to the user:

```
Found your pet!
   Name: <name>
   Personality: <personality>
```

---

## Step 2: Build Vocal Identity

Based on the pet's **name** and **personality** text, creatively design a unique
vocal identity. No template lookups — interpret the personality freely.
