Build a Developer Knowledge Graph from Claude Code Sessions (create-context-graph.dev)

A new tutorial has been released, demonstrating how to create a Developer Knowledge Graph using session history from Claude Code, imported into a Neo4j database. This full-stack application compiles all interactions from a developer's past Claude Code sessions—such as files edited, decisions made, and errors resolved—into a connected and queryable knowledge graph. By the end of the setup, users can leverage an AI agent that responds to complex queries about their coding history and preferences, enhancing productivity and insight into past projects. This development is significant for the AI/ML community as it integrates coding practices with machine learning capabilities, allowing developers to analyze and reflect on their decision-making processes, preferred coding styles, and common errors. The application facilitates eight session intelligence tools that include full-text search, decision history tracking, file modification timelines, and error pattern analysis, all while ensuring sensitive information like API keys is automatically redacted. The ease of setup, requiring only standard dependencies like Python and Node.js, broadens accessibility for developers looking to enhance their coding efficiency through intelligent data management and retrospective analysis.
