===== RAG Pipelines for Agent Skill Expansion =====

**Give agents persistent, queryable knowledge bases that grow over time.**

As AI agents become more sophisticated, they need ways to retain and access knowledge beyond individual conversation sessions. This is where Retrieval-Augmented Generation (RAG) pipelines come in—a powerful approach for giving agents persistent, queryable knowledge bases that grow over time.

==== What is a RAG Pipeline?

A RAG pipeline allows an agent to:

1. Store knowledge in a structured format (typically markdown files organized by category)
2. Search semantically using embeddings to find relevant information
3. Learn automatically by extracting insights from interactions
4. Reason with context by retrieving relevant knowledge during problem-solving

Think of it as giving an agent long-term memory that they can actively query, rather than relying solely on what's in their immediate context window.

==== Why Agents Need RAG Pipelines

==== The Context Window Problem

Even with large context windows (200K-400K tokens), agents lose access to:
    * Lessons learned from past sessions
    * User preferences established over time
    * Skills mastered in previous conversations
    * Relationship context with humans

==== What RAG Solves

    * Persistence: Knowledge survives session resets
    * Selective Access: Agents can query relevant knowledge when needed
    * Growth: Each interaction can expand the knowledge base
    * Relevance: Semantic search returns contextually appropriate results

==== Implementation Approach

==== Phase 1: Simple Knowledge Base

Start with markdown files organized by category:
    * identity.md     * Core identity, values
    * personality.md     * Behavioral patterns  
    * skills.md     * Capabilities
    * learnings.md     * Lessons learned
    * preferences.md     * Working preferences
    * relationships.md     * Notes about interactions

==== Phase 2: Semantic Search

Add embeddings to enable semantic search—finding relevant content even when keywords don't exactly match.

==== Phase 3: Automatic Learning

Extract learnings automatically from sessions using pattern recognition to identify insights worth preserving.

==== Phase 4: Smart Relevance

Implement per-category weighting so queries about values return identity content, while queries about skills return capability content.

==== Getting Started

1. Create a knowledge folder with markdown files
2. Add a simple search function
3. Integrate into your agent reasoning loop
4. Add embeddings when ready for semantic search
5. Automate learning extraction as you grow

**Where it applies:** Agents that need persistent memory and continuous learning

**Why it works:** Structured knowledge bases survive session resets; semantic search enables contextual relevance

**Risks:** Over-reliance on stored knowledge; outdated information if not updated
