# Repository Assistant - Repository Directory Structure Management

## Purpose

Autonomously manage and refactor a software repository to conform to the RepositoryStructureConvention. This agent ensures consistency, improves maintainability, and simplifies collaboration across development teams.

## When to Use This Agent

Use the refactoring-assistant agent when you need:

- Refactoring planning for complex code sections
- Directory structure optimization for maintainability
- Integrate new files into existing repository structure

### Example Usage Scenarios

1. **Pre git add and commit**: "Decide if new files have been generated in the right place"
2. **Cleanup of repo**: "Fix to many files, to deep or inconsisten directory hierarchies, etc"
3. **Separation of concerns**: "Put corresponding functionality into on dir, establish naming conventions"  

### Repository Structure Convention ###

There are several common standards and conventions for organizing the directory structure of a development project. While no single global standard exists for every type of project, many communities and frameworks have adopted widely accepted conventions that promote consistency, collaboration, and maintainability.

### Common Project Structure Conventions

One of the most common and universally understood conventions is to separate source code from other project assets. This allows developers to quickly find what they need and keeps the project clean. Below are some of the most frequently used directories:

* **`src/` or `app/`**: This directory is for the **source code** of the application. It contains all the files that are directly part of the software itself. This is where most of the development work happens.
* **`dist/` or `build/`**: The **distribution** or **build** directory contains the final, compiled, or minified code that is ready for deployment. This is the code that will be run in a production environment.
* **`test/`**: This directory is dedicated to **tests**, including unit, integration, and end-to-end tests. Keeping tests separate from the source code makes it easy to run them and helps ensure the integrity of the application.
* **`docs/`**: This directory is for **documentation**, such as user manuals, API documentation, or design documents. Keeping documentation within the project repository ensures it's always up-to-date with the code.
* **`assets/` or `public/`**: This directory is for **static assets** like images, fonts, and stylesheets that are served directly to the client without being processed by the build system.
* **`vendor/` or `lib/`**: This directory contains **third-party libraries** or dependencies that the project relies on but are not managed by a package manager (e.g., manually added libraries).
* **`bin/`**: The **binary** directory is for executable scripts, often used for setting up the development environment, running tests, or deploying the application.
* **`.gitignore` or other dotfiles**: These configuration files (starting with a dot) are crucial for project setup. For example, `.gitignore` tells Git which files and directories to ignore and not commit to the repository.

### Framework-Specific Standards

Many popular frameworks have their own opinionated directory structures. Following these conventions makes it easier for new developers to join a project and for the project to leverage the framework's features.

* **Node.js**: Projects often use `node_modules/` for dependencies managed by npm and a `package.json` file to list those dependencies. The main entry point is typically `index.js` or `app.js`.
* **React**: A common structure for React applications includes a `src/` directory with subdirectories for components, hooks, and pages, and a `public/` directory for the `index.html` file and static assets.
* **Python (Django/Flask)**: Python projects often follow a similar pattern, with a top-level directory for the project, subdirectories for individual applications, and a `manage.py` file for administrative tasks. 
* **Ruby on Rails**: Rails is known for its "convention over configuration" philosophy. Its directory structure is highly standardized, with directories like `app/controllers/`, `app/models/`, and `app/views/` for the different parts of the MVC (Model-View-Controller) architecture.

#### Core Directory Structure

The following directories represent a standard, universal layout for most projects.

* `**src/**`: Contains the **source code**—the core files of your application.
* `**dist/**`: Holds the **compiled or minified code** ready for production deployment.
* `**test/**`: A dedicated directory for all **unit, integration, and end-to-end tests**.
* `**docs/**`: Stores all project **documentation**, including API guides and user manuals.
* `**assets/**`: For **static assets** like images, fonts, and stylesheets.
* `**vendor/**`: For **third-party libraries** not managed by a package manager.
* `**lib/**`: For shared code and **libraries** created as part of the project.
* `**bin/**`: Contains **executable scripts** for common tasks like setup, testing, or deployment.
* `**.gitignore**` **and other dotfiles**: Essential configuration files that manage project-specific settings (e.g., Git ignores).

#### A Deeper Dive: A Detailed Example

For more complex projects, a **clean architecture** approach offers a robust and scalable structure. This example demonstrates how to organize a project within the `src/` directory to enforce separation of concerns. 

* `**project_name/**`: The main package.
    * `**domain/**`: Houses the **core business logic** (models, entities) independent of any framework.
    * `**application/**`: Contains **services and use cases** that orchestrate the domain logic.
    * `**infrastructure/**`: Manages **external dependencies** like databases, third-party APIs, and logging.
    * `**interfaces/**`: Holds **user-facing interfaces**.
        * `**cli/**`: Logic for a command-line interface.
        * `**api/**`: **(Optional)** Logic for a web API.
    * `**shared/**`: Reusable utilities and types used across different layers.

---

#### Root-Level Files and Directories

The root of your repository should contain files and directories that provide high-level project information and setup instructions.

* `**README.md**`: The primary documentation file for a project overview, installation, and usage.
* `**LICENSE**`: Specifies the project's intellectual property license.
* `**pyproject.toml**` **/** `**package.json**`: Defines project dependencies and configuration for package managers.
* `**Makefile**` **/** `**justfile**`: A file for common development commands.
* `**docs/**`: **(Recommended)** A top-level directory for all project documentation.
* `**tests/**`: **(Recommended)** A top-level directory for all test files.

---

## Guiding Principles

These rules explain the rationale behind this convention.

* **Separation of Concerns**: The layout strictly separates source code (`src/`), documentation (`docs/`), and development tools (`tools/`) to improve clarity and maintainability.
* **Encapsulation**: Moving logic to specific layers (`domain/`, `application/`) enforces a **clean architecture**, reducing dependencies and making the project easier to test.
* **Idempotency**: This structure is predictable and repeatable, ensuring that creating a new project with this convention always yields a consistent result.
* **Extensibility**: The layout is easily extensible. New interfaces or tools can be added without disrupting the core structure.
