arbor

Overview

Arbor is a code intelligence tool that builds a semantic dependency graph for codebases, replacing embedding-based RAG with deterministic program understanding. It offers 10 MCP tools for surgical graph traversal and architectural analysis, allowing developers to understand the blast radius of changes before making them. The tool supports multiple programming languages and integrates with various interfaces including CLI, GUI, and MCP for AI models.

FAQ

What programming languages does Arbor support?

Arbor supports production parsing and graph analysis across major ecosystems including Rust, TypeScript/JavaScript, Python, Go, Java, C/C++, C#, Dart, Kotlin, Swift, Ruby, PHP, and Shell.

How does Arbor differ from traditional RAG-based code analysis?

Arbor uses a semantic dependency graph and deterministic program understanding instead of embedding-based RAG, providing exact answers to questions like 'What breaks if I change this symbol?' instead of approximate keyword matches.

Can Arbor be used in CI/CD pipelines?

Yes, Arbor provides Git-aware risk gating with GitHub Actions and CLI commands like `arbor check --max-blast-radius` to automatically block PRs with dangerously high architectural impact.
