LLM Patterns Skill

LLM Patterns Skill

For AI-first applications where LLMs handle logical operations.

Core Principle

LLM for logic, code for plumbing.

Use LLMs for:

• Classification, extraction, summarization
• Decision-making with natural language reasoning
• Content generation and transformation
• Complex conditional logic that would be brittle in code

Use traditional code for:

• Data validation (Zod/Pydantic)
• API routing and HTTP handling
• Database operations
• Authentication/authorization
• Orchestration and error handling
