Rails LLM Integration

Production-grade LLM integration patterns for Ruby on Rails applications. USE THIS SKILL when the user needs to: integrate OpenAI, Claude, or any LLM API into a Rails app; use ruby_llm gem or langchain-rb gem in Rails; build AI-powered features in Rails; manage prompts as templates; route between LLM models for cost optimization; run LLM calls as background jobs; set up Braintrust evals; use LiteLLM or Portkey as a proxy; track LLM costs; test AI features; audit LLM usage patterns; build RAG pipelines in Rails with langchain-rb; add classification, summarization, extraction, or generation feat

# Rails LLM Integration Skill

## What This Skill Does

Teaches Claude to write LLM integrations the Rails Way -- treating LLM calls like
first-class Rails citizens alongside ActionMailer (email), ActiveJob (background work),
and ActionController (HTTP). Instead of scattered API calls, you get conventions.

## When to Use

- Adding any AI/LLM feature to a Rails application
- Using ruby_llm gem, langchain-rb gem, ruby-openai, or anthropic-rb in Rails
- Setting up prompt management, model routing, or cost tracking
- Building eval pipelines with Braintrust
- Building RAG pipelines with langchain-rb and pgvector
- Auditing existing LLM usage for anti-patterns
- Testing AI-powered features
