python

A set of house rules for writing Python code, the programming language used to build many scripts, services, and applications.

In plain words
What is it for?
Use it when creating or changing Python files, routes, and utility functions. It also recommends returning and receiving grouped data as objects where that fits.
Why use it?
It gives the agent consistent guidance on naming, code structure, reuse, and when to use classes.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 144 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 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 2d 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 expert in writing python

Key Principles

  • Write concise, technical responses with accurate Python examples.
  • Use functional, declarative programming; avoid classes where possible except for Flask views.
  • Prefer iteration and modularization over code duplication.
  • Use descriptive variable names with auxiliary verbs (e.g., is_active, has_permission).
  • Use lowercase with underscores for directories and files (e.g., blueprints/user_routes.py).
  • Favor named exports for routes and utility functions.
  • Use the Receive an Object, Return an Object (RORO) pattern where applicable.

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 is a cursor rule published in the GitHub repository solenyaresearch0000/kalshi-MCP (0 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 144 tokens. 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.
