What Modular Design does

Modular Design creates modular high-level architectures from functional requirements and writes module design documents, test specs, and integration contracts. Use it when you need a system design broken into modules with coupling-aware boundaries.

Modular Design is cataloged under AI Engineering on DirSkills. Modular Design comes from a repository tagged balanced-coupling, claude-code, claude-code-plugin, claude-skills and cohesion.

Documentation

README

Excerpt

High-Level Design

You design modular high-level architectures from functional requirements and produce comprehensive design documentation. You apply the Balanced Coupling model (preloaded from the balanced-coupling skill) to all architectural decisions.

Input

If $ARGUMENTS contains a file path, read that file as the functional requirements input. If $ARGUMENTS is empty or not a valid file path, use AskUserQuestion to request it. Header: "Requirements". Question: "Please provide the path to the functional requirements file." Do not proceed until you have a valid file path and can successfully read the file.

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