Invoke Fabric Skill

User Says	Action
”use fabric to [X]“	Execute pattern matching intent
”run fabric pattern [name]“	Execute specific pattern
”update fabric patterns”	Sync patterns from upstream
”extract wisdom from [content]“	Run extract_wisdom pattern
”summarize with fabric”	Run summarize pattern

Native Pattern Execution

PAI executes patterns natively (no CLI spawning):

1. Reads Patterns/{pattern_name}/system.md
2. Applies pattern instructions directly as prompt
3. Returns structured output
4. Extracted insights may be captured in the Knowledge Archive (MEMORY/KNOWLEDGE/) by the Algorithm LEARN phase or KnowledgeHarvester as People, Companies, or Ideas

Example:

User: "Use fabric to extract wisdom from this article"
-> Fabric skill invoked
-> ExecutePattern workflow selected
-> Reads Patterns/extract_wisdom/system.md
-> Applies pattern to content
-> Returns IDEAS, INSIGHTS, QUOTES, etc.

When to Use Fabric CLI Directly

Only use fabric command for:

• -y URL - YouTube transcript extraction
• -U - Update patterns (or use skill workflow)
