name: Fabric
description: Intelligent prompt pattern system with 240+ specialized patterns for content analysis, extraction, and transformation. USE WHEN user says 'use fabric', 'fabric pattern', 'run fabric', 'update fabric', 'update patterns', 'sync fabric', 'extract wisdom', 'summarize with fabric', 'create threat model', 'analyze with fabric', OR any request to apply Fabric patterns to content.
---

## Customization

**Before executing, check for user customizations at:**
`~/.claude/skills/CORE/USER/SKILLCUSTOMIZATIONS/Fabric/`

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.

## Voice Notification

**When executing a workflow, do BOTH:**

1. **Send voice notification**:
   ```bash
   curl -s -X POST http://localhost:8888/notify \
     -H "Content-Type: application/json" \
     -d '{"message": "Running the WORKFLOWNAME workflow in the Fabric skill to ACTION"}' \
     > /dev/null 2>&1 &
   ```

2. **Output text notification**:
   ```
   Running the **WorkflowName** workflow in the **Fabric** skill to ACTION...
   ```

# Fabric

Intelligent prompt pattern system providing 240+ specialized patterns for content analysis, extraction, summarization, threat modeling, and transformation.

**Patterns Location:** `~/.claude/skills/Fabric/Patterns/`

## Workflow Routing

| Workflow | Trigger | File |
|----------|---------|------|
| **ExecutePattern** | "use fabric", "run pattern", "apply pattern", "extract wisdom", "summarize", "analyze with fabric" | `Workflows/ExecutePattern.md` |

**Note:** To update patterns locally, run `fabric -U` to pull from the upstream fabric repo.

---

## Examples

**Example 1: Extract wisdom from content**
```
User: "Use fabric to extract wisdom from this article"
-> Invokes ExecutePattern workflow
-> Selects extract_wisdom pattern
-> Reads Patterns/extract_wisdom/system.md
-> Applies pattern to content
-> Returns structured IDEAS, INSIGHTS, QUOTES, etc.
```

**Example 2: Update patterns**
```
User: "Update fabric patterns"
-> Invokes UpdatePatterns workflow
-> Runs git pull from upstream fabric repository
-> Syncs patterns to local Patterns/ directory
-> Reports pattern count
```

**Example 3: Create threat model**
```
User: "Use fabric to create a threat model for this API"
-> Invokes ExecutePattern workflow
-> Selects create_threat_model pattern
-> Applies STRIDE methodology
-> Returns structured threat analysis
```

## Quick Reference

### Pattern Execution (Native - No CLI Required)

Instead of calling `fabric -p pattern_name`, PAI executes patterns natively:
1. Reads `Patterns/{pattern_name}/system.md`
2. Applies pattern instructions directly as prompt
3. Returns results without external CLI calls

### When to Use Fabric CLI Directly

Only use `fabric` command for:
- **`-y URL`** - YouTube transcript extraction
- **`-u URL`** - URL content fetching (when native fetch fails)

### Most Common Patterns

| Intent | Pattern | Description |
|--------|---------|-------------|
| Extract insights | `extract_wisdom` | IDEAS, INSIGHTS, QUOTES, HABITS |
| Summarize | `summarize` | General summary |
| 5-sentence summary | `create_5_sentence_summary` | Ultra-concise |
| Threat model | `create_threat_model` | Security threat analysis |
| Analyze claims | `analyze_claims` | Fact-check claims |
| Improve writing | `improve_writing` | Writing enhancement |
| Code review | `review_code` | Code analysis |
| Main idea | `extract_main_idea` | Core message extraction |

### Full Pattern Catalog

See `PatternCatalog.md` for complete list of 240+ patterns organized by category.

## Native Pattern Execution

**How it works:**

```
User Request → Pattern Selection → Read system.md → Apply → Return Results
```

**Pattern Structure:**
```
Patterns/
├── extract_wisdom/
│   └── system.md       # The prompt instructions
├── summarize/
│   └── system.md
├── create_threat_model/
│   └── system.md
└── ...240+ patterns
```

Each pattern's `system.md` contains the full prompt that defines:
- IDENTITY (who the AI should be)
- PURPOSE (what to accomplish)
- STEPS (how to process input)
- OUTPUT (structured format)

---

## Pattern Categories

| Category | Count | Examples |
|----------|-------|----------|
| **Extraction** | 30+ | extract_wisdom, extract_insights, extract_main_idea |
| **Summarization** | 20+ | summarize, create_5_sentence_summary, youtube_summary |
| **Analysis** | 35+ | analyze_claims, analyze_code, analyze_threat_report |
| **Creation** | 50+ | create_threat_model, create_prd, create_mermaid_visualization |
| **Improvement** | 10+ | improve_writing, improve_prompt, review_code |
| **Security** | 15 | create_stride_threat_model, create_sigma_rules, analyze_malware |
| **Rating** | 8 | rate_content, judge_output, rate_ai_response |

## Integration

### Feeds Into
- **Research** - Fabric patterns enhance research analysis
- **Blogging** - Content summarization and improvement
- **Security** - Threat modeling and analysis

### Uses
- **fabric CLI** - For YouTube transcripts (`-y`) and URL fetching (`-u`)
- **Native execution** - Direct pattern application (preferred)
