Graph-Augmented
Code Intelligence Engine

A structural code intelligence engine that treats repositories as connected program structure — not flat text chunks.

The system combines semantic code units, program relationships, hybrid retrieval, graph-aware ranking, and context selection for repository-scale code understanding.

Code is more than text

Program structure itself is a retrieval signal.

Lexical search finds matching terms. Semantic retrieval finds conceptually similar code. Graph-aware retrieval also uses structural relationships — calls, references, imports, inherits, and contains — as evidence beyond text similarity alone.

Intelligence pipeline

A layered pipeline separates program analysis, retrieval, ranking, and context compilation from downstream language generation.

LLM ≠ Code Intelligence Engine — parsing, graph construction, retrieval, ranking, and evaluation remain independent of an optional downstream LLM consumer.

Engineering highlights

Design principles

Three ideas at the center of the engine's architecture. Designed so graph-aware retrieval can be evaluated against text-only baselines rather than assumed to improve results.

Highlight 01

Semantic code units

Functions, classes, methods, and meaningful symbols preserve program boundaries better than arbitrary fixed text chunks.

Highlight 02

Graph-augmented retrieval

Program relationships — calls, references, imports, and inherits — can provide retrieval evidence that textual similarity alone may miss.

Highlight 03

LLM outside the engine

The intelligence pipeline is designed around deterministic program analysis, retrieval, ranking, and context construction, with an LLM acting only as an optional downstream consumer.
