python-projects-guide-cursorrules-prompt-file is a cursor rule for Cursor from PatrickJS/awesome-cursorrules. It costs 211 tokens per session, scanned A, original, CC0-1.0.

A set of Cursor instructions for organizing Python projects with separate source, test, documentation, and configuration areas. It also specifies tools for dependencies, formatting, testing, CI, and writing code that is easier for an AI assistant to understand.

In plain words
What is it for?
Use it when building Python projects with pytest, Ruff, type hints, environment variables, virtual environments, and automated checks through GitHub Actions or GitLab CI.
Why use it?
It reduces inconsistency in project structure and makes Python code easier to test, document, review, and maintain.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

python-projects-guide-cursorrules-prompt-file scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
