SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Compute the precise blast radius of a monorepo change, including affected packages, CI jobs, and CODEOWNERS.

Core Features & Use Cases

  • Live-tool guided blast-radius analysis across Nx, Turborepo, Bazel, pnpm workspaces, and other mono layouts.
  • Cross-language graph support (TypeScript, Python, Go, proto, Docker) with reverse-dependency tracing.
  • CODEOWNERS-driven ownership and CI impact surface to help plan reviews and releases.
  • Use Case: When changing a shared utility, determine downstream impacts to plan PR scope and notify teams.

Quick Start

Run the monorepo-impact-radius skill on your PR to surface affected packages, owners, and CI impact.

FAQPage Schema
How do I determine the blast radius of a change in a monorepo?

To determine monorepo blast radius, you traverse direct and transitive dependencies to surface affected packages, CI jobs, and CODEOWNERS. This analysis reads existing docs and maps downstream impacts without building or editing configuration.

How do I find affected packages and CI jobs when modifying a shared utility in a monorepo?

Finding affected packages and CI jobs involves tracing reverse dependencies across your monorepo graph. This surfaces the precise downstream impact of changing a shared utility, helping you plan PR scope and notify relevant teams.

Can I analyze cross-language dependency graphs for TypeScript, Python, and Go in the same monorepo?

Yes, you can analyze cross-language dependency graphs spanning TypeScript, Python, Go, proto, and Docker. The blast radius analysis applies reverse-dependency tracing across these mixed-language graphs to identify all affected packages.

Does monorepo blast radius analysis work with Nx, Turborepo, and Bazel toolchains?

Yes, blast radius analysis works with Nx, Turborepo, Bazel, and pnpm workspaces. It uses these live toolchain guided graphs to compute the precise impact of your changes, including affected packages and CI surfaces.

What is the best way to identify CODEOWNERS for a monorepo change without editing configuration files?

The best way to identify CODEOWNERS for a monorepo change is using a blast radius analysis that surfaces ownership driven by the dependency graph. It reads existing docs and traverses dependencies to map ownership without editing configuration.
