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:

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 &

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:

• Reads Patterns/{pattern_name}/system.md

• Applies pattern instructions directly as prompt

• 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)
