Embabel Agent RAG Core - Improved Tile

This is an improved version of the RAG Core tile documentation, optimized for coding agent efficiency through progressive disclosure and task-oriented organization.

What's Different?

This improved tile reorganizes the original 13-file flat structure into a 4-level hierarchy with 17 files, providing:

• Progressive Disclosure: Start simple, add complexity as needed
• Task-Oriented Guides: Jump directly to "how to" accomplish specific tasks
• Better Navigation: Clear hierarchy from basics to advanced topics
• Optimal File Sizing: Right-sized content for specific purposes
• 100% Content Preservation: All original APIs and details maintained

Quick Start for Coding Agents

I want to... (Use Cases)

Set up a basic RAG pipeline → Start with docs/index.md (Task 1) → Details in docs/quickstart/basic-rag-pipeline.md

Implement vector search with filters → Start with docs/index.md (Task 2) → Details in docs/quickstart/vector-search.md

Manage entities and relationships → Start with docs/index.md (Task 3) → Details in docs/quickstart/entity-management.md

Integrate RAG with LLM tools → Details in docs/quickstart/llm-integration.md

Understand a specific API → Browse docs/api-reference/

Implement custom behavior → See docs/advanced/architecture.md for extensibility points → Check specific advanced guides for patterns

Test my implementation → Use docs/utilities/support-utilities.md for in-memory implementations

Reading Paths

Path 1: Quick Start (5-10 minutes)

1. Read docs/index.md sections:
   • Package Information
   • Core Concepts
   • Quick Start Tasks (pick relevant task)
2. Copy/adapt example code
3. ✅ Working implementation

Path 2: Comprehensive Understanding (30-45 minutes)

1. Read docs/index.md completely
2. Read relevant quickstart guides:
   • basic-rag-pipeline.md
   • vector-search.md
   • entity-management.md
3. Scan API reference for capabilities:
   • data-models.md
   • search-operations.md
4. ✅ Full understanding of capabilities

Path 3: Advanced/Custom Implementation (1-2 hours)

1. Complete Path 2 first
2. Read docs/advanced/architecture.md for design principles
3. Study relevant advanced topics:
   • custom-transformers.md
   • content-refresh-policies.md
   • spring-ai-integration.md
4. Reference detailed API docs as needed
5. ✅ Custom implementation with production patterns

Key Features for Agents

Progressive Disclosure

• Level 1 (Index): Overview + essential APIs + common tasks (444 lines)
• Level 2 (Quickstart): Task-oriented guides with working examples (300-500 lines each)
• Level 3 (API Reference): Comprehensive API documentation (500-1000 lines each)
• Level 4 (Advanced): Edge cases, extensibility, architecture (800-1000 lines each)

Task-Oriented Organization

Every common task has a dedicated guide:

• Basic RAG Pipeline: Parse → Chunk → Store → Search
• Vector Search: Semantic similarity with filtering
• Entity Management: CRUD + relationships + navigation
• LLM Integration: Expose RAG as tool for LLMs

Optimal Context Loading

• Small tasks: Load 400-700 lines (index + quickstart)
• Medium tasks: Load 1,000-1,500 lines (index + quickstart + API ref)
• Complex tasks: Load 2,000-2,500 lines (index + multiple guides)
• 60-70% reduction vs. original tile

Complete API Coverage

• All API blocks marked with { .api } for easy identification
• ~150 API code blocks across all documents
• 25+ essential APIs in index.md for quick reference
• Comprehensive API reference for deep dives

File Size Guide

Comparison to Original

All API Blocks Marked

Every API code block includes the { .api } marker:

// Example API block
interface Example {
    fun method(): ReturnType
}

This enables easy identification and extraction of API definitions.

Content Completeness

✅ All content from original tile preserved ✅ All APIs documented ✅ All examples included ✅ Additional patterns and edge cases added ✅ Expanded architecture documentation ✅ Testing patterns included ✅ Production deployment patterns added

Usage Tips for Coding Agents

For Maximum Efficiency:

1. Start with index.md - Get oriented in <5 minutes
2. Use quickstart guides - Get working code in <10 minutes
3. Reference API docs - Get comprehensive details as needed
4. Explore advanced topics - When building custom implementations

For Best Results:

• Don't read everything: Progressive disclosure means you only need what's relevant
• Follow cross-references: Documents link to related content
• Use task-based navigation: Know what you want to do? Go directly to that quickstart
• Check examples first: Most guides include multiple working examples

For Testing:

• Use InMemoryNamedEntityDataRepository from utilities for unit tests
• See testing patterns in each quickstart guide
• Production patterns in advanced docs include error handling and resilience

Installation

Add to your Maven project:

<dependency>
    <groupId>com.embabel.agent</groupId>
    <artifactId>embabel-agent-rag-core</artifactId>
    <version>0.3.3</version>
</dependency>

See docs/index.md for complete setup instructions.

Feedback

This improved tile was created to optimize documentation for coding agent consumption through progressive disclosure and task-oriented organization. The goal is to enable agents to find relevant information quickly and efficiently while maintaining comprehensive coverage of all features.
