# brand-voice

Manage writing profiles to maintain consistent tone and style per brand. Selectable via `--voice` option in all content creation skills.

## Brand Profiles

### 🐧 무펭이 (Default)
- **Tone**: Friendly and casual
- **Style**: Informal, emoji usage 🐧
- **Format**: Core points only, mix in humor
- **Examples**:
  - ❌ "Hello! Today I'll introduce MUFI Photobooth's new features."
  - ✅ "Yo MUFI Photobooth new feature dropped 🐧 This is insane fr"

### 🎯 MUFI Official
- **Tone**: Professional and polite
- **Style**: Formal language, formal expressions
- **Format**: Clean and clear, for B2B/official channels
- **Examples**:
  - ✅ "MUFI Photobooth is the optimal solution for university festivals. Easy setup and intuitive UI enable anyone to use it easily."

### 👤 Hyungnim Personal
- **Tone**: Casual but insightful
- **Style**: Mix casual/formal, experience-centered
- **Format**: Flow of thought, insights worth sharing
- **Examples**:
  - ✅ "Running booths at festivals, what I realized is that people ultimately want 'fun'. No matter how good the tech, if UX is complex, they won't use it."

## Profile File Location

**Location**: `workspace/brand/profiles/`

Each profile `.md` file defines: Tone, Style, Format, Forbidden Expressions, Preferred Expressions, and Examples. See existing profiles (`mupengyi.md`, `mufi-official.md`, `hyungnim.md`) for the expected structure.

## Writing Skill Integration

These skills support `--voice` option:

- **copywriting**: Caption/copy writing
- **cardnews**: Card news text
- **social-publisher**: SNS posts
- **mail**: Email writing
- **content-recycler**: Content recycling

### Usage Examples

```
"Write Insta caption --voice mufi-official"
→ Write in MUFI official tone

"Create card news --voice mupengyi"
→ Create in 무펭이 style

"Write Threads post in Hyungnim tone"
→ Use Hyungnim personal profile
```

## Profile Switching Guide

### Platform Recommendations
- **Instagram MUFI official account** → `mufi-official`
- **Instagram personal account** → `hyungnim`
- **Threads** → `mupengyi` (casual)
- **Discord/DM** → `mupengyi`
- **Official email** → `mufi-official`
- **Blog posts** → `hyungnim` (insight-focused)

### Situation Recommendations
- **Product introduction** → `mufi-official`
- **Daily sharing** → `mupengyi` or `hyungnim`
- **Customer service** → `mufi-official`
- **Community engagement** → `mupengyi`

## Workflow

1. **Determine profile** — resolve from `--voice` flag, or use platform defaults (see Profile Switching Guide above)
2. **Load profile** — read the matching `.md` from `workspace/brand/profiles/`
3. **Write content** — apply the profile's tone, style, format, and preferred expressions
4. **Validate** — check that no forbidden expressions appear and tone matches the target profile
5. **Flag mismatches** — warn if content drifts from the selected voice before finalizing

## Integration Notes

Keep the integration contract lightweight but explicit:

- **Pre-check** — before a writing skill runs, confirm the selected profile (or default) is known
- **Post-check** — after drafting, validate forbidden/preferred expressions and overall tone fit
- **Usage logging (optional)** — if the workspace tracks writing activity, record the selected voice/profile for later review

This skill does not require a specific hook engine or event bus implementation, but any automation around it should preserve the same pre-check → write → validate flow.

## Adding New Profiles

To create a new brand profile, add a `.md` file to `workspace/brand/profiles/` following the same structure (Tone, Style, Format, Forbidden Expressions, Preferred Expressions, Examples).
