Codebase knowledge graphs for AI assistants

What is a codebase knowledge graph?

A codebase knowledge graph is a connected representation of code symbols, files, dependencies, documentation, and design notes. Instead of treating a repository as isolated text chunks, Graphify models how implementation parts relate to each other.

• Connect imports, calls, classes, functions, docs, and rationale comments.
• Keep graph structure separate from any single prompt or chat session.
• Make architectural relationships visible through graph.html and reusable through graph.json.

Why does a graph help AI coding assistants?

AI coding assistants perform better when they can follow explicit relationships. A graph gives the assistant paths, communities, and dependency context that plain keyword search or chunk retrieval may not expose.

• Path lookups show how files and subsystems influence each other.
• Community clustering helps assistants reason about subsystem boundaries.
• Structured reports give reviewers and assistants the same shared context.

When should a team build a repository graph?

Build a graph before onboarding, architecture review, refactoring, migration planning, or incident handoff. These workflows need durable relationships between code and context, not just one-time retrieval.

• Create a baseline before a large refactor or migration.
• Refresh graph artifacts after major architectural changes.
• Use the graph as a handoff artifact for new engineers and AI assistants.
