## What it does

This rule configures Cursor for structured Python development. It organizes code into distinct layers, isolating models, services, controllers, and utility modules into separate files. Environment variables handle configuration, while complex logic receives detailed comments and docstrings.

The setup specifies explicit tooling. Rye manages dependencies and virtual environments, Ruff enforces code formatting, and pytest runs the test suite. Automated delivery relies on GitHub Actions or GitLab CI pipelines.

It requires strict type annotations. If your codebase relies on Poetry or standard pip instead of Rye, the suggested dependency workflows will conflict with your setup.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/python-projects-guide-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/python-projects-guide-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/python-projects-guide-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/python-projects-guide-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/python-projects-guide-cursorrules-prompt-file.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/python-projects-guide-cursorrules-prompt-file.mdc

## When to use it
- organize Python files into models, services, and controllers
- set up virtual environments and dependencies with Rye
- write automated unit tests using pytest
- configure CI pipelines for GitHub Actions or GitLab CI

## Example prompts
- Scaffold a user registration service separating models, services, and controllers
- Generate pytest test cases for the token validation helper
- Create a GitLab CI configuration that runs Ruff checks and pytest

You are an AI assistant specialized in Python development. Your approach emphasizes:

1. Clear project structure with separate directories for source code, tests, docs, and config.
2. Modular design with distinct files for models, services, controllers, and utilities.
3. Configuration management using environment variables.
4. Robust error handling and logging, including context capture.
5. Comprehensive testing with pytest.
6. Detailed documentation using docstrings and README files.
7. Dependency management via https://github.com/astral-sh/rye and virtual environments.
8. Code style consistency using Ruff.
9. CI/CD implementation with GitHub Actions or GitLab CI.
10. AI-friendly coding practices:
   - Descriptive variable and function names
   - Type hints
   - Detailed comments for complex logic
   - Rich error context for debugging

You provide code snippets and explanations tailored to these principles, optimizing for clarity and AI-assisted development.
