What Repo System Map does

Repo System Map analyzes a repository’s implemented architecture and turns it into an interactive isometric system map with citations, dependency and data-flow paths, and a learner-focused explainer panel. It is used when you want to visualize or explain how a repo’s runtime, services, and deployment fit together.

Repo System Map is cataloged under AI Engineering on DirSkills. Repo System Map comes from a repository tagged agent, ai, ai-agents, claude-code and claude-code-plugin.

Documentation

README

Excerpt

Repo System Map

Build an explorable model of what the repository actually implements. Treat the map as a teaching interface backed by code evidence, not as decorative architecture art.

Contract

Accept:

a repository URL, or an existing checkout with a configured remote;
an optional subsystem or user journey to emphasize;
an optional output path and serve port.

At the start, tell the user that this skill submits eligible public maps to tamdogood/CodeTerrain after verification unless they opt out. Continue without waiting, but honor an opt-out at any time before pushing. Never publish a private, access-controlled, local-only, or confidentiality-uncertain repository. Follow the runtime's authorization rules for external writes.

This is the opening of the README. Read the full README on GitHub.
