# SKILL.md - Contextual Enrichment in LLMs (RAG Evolution)

## Paper Reference
- **arXiv:** 2604.03174
- **Title:** Beyond the Parameters: A Technical Survey of Contextual Enrichment in Large Language Models
- **Utility Score:** 0.85
- **Authors:** Shivangi Agarwal et al.
- **Date:** April 2026

## Core Insights

### Problem Addressed
LLMs limited by:
- Static knowledge
- Finite context windows
- Weakly structured causal reasoning

### Augmentation Spectrum
Ranked by degree of structured context:

1. **In-Context Learning & Prompt Engineering**
   - Minimal structure
   - Ad-hoc prompting

2. **Retrieval-Augmented Generation (RAG)**
   - Document retrieval
   - Unstructured context injection

3. **GraphRAG**
   - Graph-structured retrieval
   - Entity relationship preservation

4. **CausalRAG**
   - Causal structure in retrieval
   - Reasoning-aware augmentation

## Practical Applications

### Deployment Decision Framework
```markdown
Assess needs:
1. Knowledge freshness → RAG needed
2. Entity relationships → GraphRAG
3. Causal reasoning → CausalRAG
4. Context limits → Determine augmentation level

Choose augmentation based on:
- Task complexity
- Reasoning requirements
- Domain structure
- Latency constraints
```

### Literature Screening Protocol
- Transparent filtering methodology
- Cross-paper evidence synthesis
- Higher-confidence vs. emerging results distinction

## Key Takeaways
- Contextual enrichment is a spectrum, not a single technique
- More structure → better reasoning, higher cost
- RAG evolution: documents → graphs → causal
- Decision framework for deployment choices

## Related Work
- Classic RAG implementations
- Graph-based knowledge systems
- Causal reasoning in NLP
