Customization

Before executing, check for user customizations at: ~/.claude/skills/PAI/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:

   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...

Workflow Routing

Workflow	Trigger	File
ExecutePattern	"use fabric", "run pattern", "apply pattern", "extract wisdom", "summarize", "analyze with fabric"	Workflows/ExecutePattern.md
UpdatePatterns	"update fabric", "update patterns", "sync fabric", "pull patterns"	Workflows/UpdatePatterns.md

---

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
