rgctl policy checks let you define architectural constraints as JSON and enforce them in CI. This post walks through the CoolStore WebLogic monolith as a worked example -- policy file format, violation types, blast-radius gates, and a working GitHub Actions workflow.

rgctl turns any repository into a queryable knowledge graph with pre-computed reachability, blast radius, program slicing, taint analysis, and community detection. Built in Rust for speed, designed for LLM agents and humans alike.

How rgctl indexes Magento Open Source into a structural graph for coding agents — custom PHP Tier 1 plugin, shallow vs deep discover, honest limits on DI-heavy frameworks, and copy-paste agent workflows.

If you use Cursor or Claude Code on large repos, blast radius gives your agent bounded structural facts instead of grep guesses. A Kubernetes walkthrough for engineers: what to expect, when it helps, and when your IDE is still the better tool.

A concrete decomposition of a Java EE monolith into microservices using rgctl's community detection, blast radius analysis, and CPG field mutation tracking to identify natural service boundaries and quantify coupling at each cut.
