python-general

A set of coding rules for Python projects, covering language version, formatting, type hints, documentation, file paths, debugging, dependencies, and how to run the application.

In plain words
What is it for?
Use it when writing or reviewing Python 3.10+ code, adding packages with uv, running the project, defining functions, handling paths and errors, and following the repository's style rules.
Why use it?
It keeps Python code consistent and easier to maintain across the project. It also standardizes commands and practices for a stack using Docker Compose, PostgreSQL, and Loguru.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-general 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 yesterday.

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

General Guidelines

  • Use Python 3.10+ syntax.
  • Follow PEP 8 coding standards.
  • Include type hints for all function definitions.
  • Add docstrings to all public classes and functions.
  • Prefer pathlib over os.path for file system operations.
  • Utilize f-strings for string formatting.
  • Avoid using wildcard imports.
  • Use print(f"{var_name=}") or logger.debug(f"{var_name=}") for debugging.
  • Write idiomatic and readable code.
  • Do not write comments for tests
  • Do not write comments where you are describing what was changed
  • Do not wtrite try/except blocks for large blocks of code, but only for specific lines where exceptions are expected.
  • Do not use "from typing install List, Dict, Option", but use python 3.10+ syntax like list, dict, and |.
  • Use "" (double quotes) for strings and '' (single quotes) for chars only
  • Before use regexp compile them in the top of a file

Tech stack

  • docker compose
  • postgresql
  • loguru

Package management

  • Use uv add to install python packages
  • Use uv run to run the project or scripts

Run project

  • run project using docker compose (look docker-compose.yaml)

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.

python-general is a cursor rule published in the GitHub repository dmitriiweb/article-scraper-mcp (2 stars, last pushed 1y ago), licensed MIT. It adds 287 tokens to every session, about $0.0014 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
