## Why Included

Graph-shaped context can expose relationships and document structure that vector search or Text-to-SQL misses. Treat it as an additional retrieval surface, then benchmark it against your own data.

## Source Summary

The workshop builds graph representations over lakehouse tables and documents, letting an agent inspect metadata, traverse linked document hierarchies, and detect document communities. Tool calls are exposed through **MCP history** in the demonstrated setup.

## Practical Implication

Give data agents several context shapes rather than one universal query path. Use a metadata graph to plan SQL, linked views for document neighborhoods, and **community detection** when thematic grouping helps investigation.

## Agent-Ready Context

The workshop builds graph representations over lakehouse tables and documents, letting an agent inspect metadata, traverse linked document hierarchies, and detect document communities. Tool calls are exposed through **MCP history** in the demonstrated setup.

Give data agents several context shapes rather than one universal query path. Use a metadata graph to plan SQL, linked views for document neighborhoods, and **community detection** when thematic grouping helps investigation.

The workshop reports **no accuracy benchmark** for the demonstrated system. Its structured and unstructured graphs are also unlinked, leaving the agent to join extracted identifiers at runtime unless builders add deterministic connections.

## Context Map

- Layer: context
- Domains: data
- Topics: context-engineering, retrieval, mcp

## Uncertainty

- The workshop reports **no accuracy benchmark** for the demonstrated system. Its structured and unstructured graphs are also unlinked, leaving the agent to join extracted identifiers at runtime unless builders add deterministic connections.
