# Skill Factory - High-Quality Skill Creation System

## Skill Metadata

| Field | Value |
| ----- | ----- |
| Version | 2.1.0 |
| Tier | Special |
| Auto-load | Proactively when building Skills |
| Purpose | Interactive discovery → Web research → Skill generation |

---

## What It Does

Interactive discovery, web research, continuous updates를 통한 고품질 Claude Code Skill 생성 및 유지관리 시스템을 제공합니다.

**Core capabilities**:
- ✅ Interactive user surveys via `moai-alfred-interactive-questions`
- ✅ Web research for latest information (WebFetch/WebSearch)
- ✅ Skill analysis and update recommendations
- ✅ Official documentation validation
- ✅ Progressive Disclosure pattern
- ✅ Multi-model compatibility testing

---

## When to Use

- 새로운 Skill 패키지를 생성할 때
- 최신 best practices와 공식 문서를 조사할 때
- 기존 Skill을 분석하고 업데이트할 때
- Skill generation workflow를 orchestrate할 때

---

## Core Principles

### 1. Conciseness Over Completeness
- SKILL.md should stay **under 500 words**
- Trust that Claude is already intelligent—provide guidance, not lectures
- Reference patterns, provide decision trees, link to supporting files

### 2. Appropriate Freedom Levels

| Freedom Level | When to Use | Content Style |
| ------------- | ----------- | ------------- |
| **High** | Flexible, creative work | Principles, trade-offs, considerations |
| **Medium** | Standard patterns exist | Pseudocode, flowcharts, annotated code |
| **Low** | Deterministic, error-prone | Specific scripts with error handling |

### 3. Three-Level Progressive Disclosure

```
Level 1: Metadata (Always Active)
├── name, description, allowed-tools
└── ~100 tokens total
    ↓
Level 2: Instructions (On Demand)
├── SKILL.md main body
└── Loads when Claude recognizes relevance
    ↓
Level 3: Resources (As Needed)
├── reference.md, examples.md
└── Consumed when explicitly referenced
```

---

## Quick Start: Creating a Skill

### 5-Step Process (Total: ~2 hours)

1. **Define Problem** (10 min): What gap does this Skill fill?
2. **Design Metadata** (10 min): Name (gerund + domain), description, allowed-tools
3. **Structure Content** (30 min): High (20%) + Medium (50%) + Low (30%) freedom
4. **Add Examples & References** (30 min): 3-4 examples, detailed reference
5. **Validate & Test** (20 min): CHECKLIST.md, multi-model testing

---

## YAML Metadata Requirements

### Frontmatter Structure

```yaml
---
name: "Skill Name"
description: "What it does and when to use it"
allowed-tools: "Tool1, Tool2, Tool3"
---
```

### Field Specifications

**`name`** (Required):
- Max 64 characters
- Format: Gerund (action verb) + domain
- Example: "Processing CSV Files with Python"

**`description`** (Required):
- Max 1024 characters
- Format: Third person, action-oriented
- Must include: capabilities + trigger scenarios + 3+ keywords

**`allowed-tools`** (Recommended):
- Minimal principle: Only tools actually used
- Format: Comma-separated list
- Example: `"Read, Write, Edit, Bash(git:*)"`

> **Detailed metadata guide**: See [METADATA.md](METADATA.md)

---

## File Organization

### Recommended Structure

```
skill-name/
├── SKILL.md                    # Main instructions (~500 words)
├── reference.md                # Detailed specs, API docs
├── examples.md                 # 3-4 real-world examples
├── CHECKLIST.md                # Quality validation (optional)
├── scripts/                    # Utility scripts
└── templates/                  # Reusable templates
```

### Rules

| Rule | Rationale |
|------|-----------|
| One level deep | Avoids nested discovery |
| Relative paths | Cross-platform compatibility |
| Forward slashes | Unix convention |
| <500 lines per file | Manageable context |

> **Detailed organization guide**: See [STRUCTURE.md](STRUCTURE.md)

## Quality Validation

Before publishing, audit your Skill:

### Metadata Completeness
- [ ] `name` ≤ 64 characters, gerund format
- [ ] `description` ≤ 1024 chars, includes 3+ triggers
- [ ] `allowed-tools` is minimal and justified

### Content Quality
- [ ] SKILL.md ≤ 500 words
- [ ] All major concepts have examples
- [ ] Terminology is consistent
- [ ] Progressive Disclosure applied

### Multi-Model Compatibility
- [ ] Haiku can understand concise examples
- [ ] Sonnet exploits full Skill capabilities
- [ ] Opus can extend patterns beyond examples

> **Complete validation checklist**: See [CHECKLIST.md](CHECKLIST.md)

---

## Advanced Features

### Interactive Discovery
Use TUI surveys to clarify vague requirements and capture all user needs.

> **Detailed guide**: [INTERACTIVE-DISCOVERY.md](INTERACTIVE-DISCOVERY.md)

### Web Research
Gather latest information, best practices, and official documentation.

> **Detailed guide**: [WEB-RESEARCH.md](WEB-RESEARCH.md)

### Skill Update Advisor
Analyze existing Skills and propose updates based on latest information.

> **Detailed guide**: [SKILL-UPDATE-ADVISOR.md](SKILL-UPDATE-ADVISOR.md)

## Common Failure Modes

| Issue | Root Cause | Fix |
|-------|------------|-----|
| **Not activating** | Description too generic | Add 5+ specific keywords |
| **Haiku ignores it** | Examples too complex | Simplify pseudocode |
| **Over-specifying** | Too much low-freedom content | Increase principles |
| **Scope creep** | Covers too many domains | Split into 2-3 focused Skills |
| **File too large** | SKILL.md > 500 words | Move content to reference.md |
