Structural graph technology identifies the inherent mathematical properties and forbidden configurations of complex networks to design optimal algorithms.

Structural graph theory moves beyond simple node-and-edge visualization to characterize the fundamental architecture of a network. By utilizing concepts like treewidth, graph minors, and modular decomposition, this technology allows engineers to determine if a specific graph belongs to a family with known efficient solutions. This precision is critical for solving NP-hard problems in logistics, where identifying a planar or bounded-degree structure can reduce exponential computation times to linear or polynomial scales. Whether it is optimizing the layout of a 5nm semiconductor or managing millions of concurrent connections in a social network, structural graph analysis provides the formal framework to prove algorithm reliability and performance limits.

keel is a pure Rust CLI tool that builds a fast, incrementally-updated structural graph of your codebase and enforces architectural contracts at generation time — not at review time, not at build time. When an LLM coding agent modifies your code, keel immediately validates that the change doesn't break callers, violate type contracts, or introduce structural drift. Think of it as a structural linter purpose-built for the age of AI-generated code.
