Introducing rgctl: A Code Knowledge Graph for Engineering Teams and Agents

rgctl is an open-source Rust tool (MIT license) that indexes a codebase once into a persistent, mmap-backed knowledge graph with pre-computed reachability bitsets, then answers structural queries like blast radius, program slicing, taint analysis, and community detection in sub-millisecond time. It exposes a Cypher-like Graph Query Language, CI policy checks, semantic search, and migration planning (including Konveyor/Kantra rule integration for Java EE to Quarkus moves). It's built specifically for LLM coding agents: JSON output, deterministic results, and an installable Claude Code/Cursor skill that lets agents query architecture facts instead of re-reading files every session. Supports ten Tier 1 languages including Rust, Python, Java, Go, TypeScript, and PHP. An end-to-end orchestrator called MigIQ builds on top of it for automated migrations.
