## What is this?

This project bridges [Daniel Miessler's Fabric](https://github.com/danielmiessler/fabric) prompt library with [Claude's skill system](https://docs.anthropic.com/). Instead of memorizing 250+ individual patterns, you get 7 intelligent skills that route to the right pattern based on what you actually ask.

**Before:** "Should I use `analyze_paper`, `summarize_paper`, `extract_references`, or `extract_wisdom`?"

**After:** "Help me understand this paper" → The skill figures it out.

---

## Quick Start

### Installation

1. Download the skills you need from the [Releases](https://github.com/spitoglou/fabric-claude-skills/tree/HEAD/../../releases) page
2. Extract to your Claude skills directory:
   ```bash
   # Example for a single skill
   unzip research-intelligence.skill -d ~/.claude/skills/
   ```
3. The skill is now available in Claude

### Or clone the entire repository:

```bash
git clone https://github.com/spitoglou/fabric-claude-skills.git
cd fabric-claude-skills

# Copy all skills to Claude's skill directory
cp -r skills/* ~/.claude/skills/
```

## Architecture

Each skill follows a consistent structure optimized for Claude's context window:

```
skill-name/
├── SKILL.md           # Routing logic + pattern selection (always loaded)
└── references/
    ├── pattern_1.md   # Full pattern (loaded on-demand)
    ├── pattern_2.md
    └── pattern_n.md
```

### Design Principles

1. **Progressive Disclosure** - SKILL.md contains routing logic; full patterns load only when needed
2. **Intent-Based Routing** - Patterns grouped by user goal, not output format
3. **Decision Trees** - Smart routing based on request context, not just keywords
4. **Steelman First** - Critical analysis patterns present strongest arguments before critiquing
5. **Chaining Support** - Skills suggest logical follow-up patterns

### SKILL.md Structure

```markdown
---
name: skill-name
description: What this skill does. Trigger phrases and use cases.
---

# Skill Name

## Pattern Selection
| Intent | Pattern | When to Use |
|--------|---------|-------------|
| [goal] | `pattern_name` | [context] |

## Decision Flow
[Routing logic as text or diagram]

## Pattern References
[Links to reference patterns]

## Output Guidelines
[Consistency requirements]

## Chaining Suggestions
[Logical follow-ups]
```

---

## Creating New Skills

Want to add patterns or create new skills? Follow these steps:

### 1. Identify Pattern Clusters

Group Fabric patterns by **user intent**, not output format. Ask: "What goal do these patterns serve?"

### 2. Create the Skill Structure

```bash
mkdir -p skills/my-skill/references
```

### 3. Write SKILL.md

Keep it under 500 lines. Include:
- YAML frontmatter with name, description, triggers
- Pattern selection table
- Decision flow logic
- Output guidelines

### 4. Adapt Patterns

Don't copy Fabric patterns directly. Adapt them:
- Add structured OUTPUT INSTRUCTIONS
- Include example outputs
- Ensure consistent formatting

### 5. Test Routing

Verify the skill routes correctly for various phrasings of the same intent.

### Contributing

1. Fork the repository
2. Create a feature branch (`git checkout -b skill/my-new-skill`)
3. Add your skill following the structure above
4. Submit a pull request with:
   - Description of the skill's purpose
   - List of patterns included
   - Example use cases
