What is copilot-kit python.instructions.md?

A set of rules for writing Python code, including formatting, naming, type hints, imports, and safer handling of inputs and secrets. It also requires reading the project’s Python-pattern guidance before changing Python code.

Use it when creating, editing, or reviewing Python files, especially code that handles external input, database queries, tokens, or application services.

It gives the coding agent consistent project standards to follow instead of making style and security decisions from scratch. This reduces inconsistent code and common unsafe practices.

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.

Model	Per session	Once invoked
Fable 5	$0.00351	$0.00351
Opus 5	$0.00176	$0.00176
Sonnet 5	$0.00070	$0.00070
Haiku 4.5	$0.00035	$0.00035

Security

Grade A, and why

copilot-kit python.instructions.md 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

Python Standards

🎯 Before Any Python Work

READ: .github/skills/python-patterns/SKILL.md

📋 Code Style (PEP 8)

4 spaces for indentation (NOT tabs)
Maximum line length: 88 characters (Black formatter)
Two blank lines before top-level definitions
One blank line between methods

🔧 Naming Conventions

Type	Convention	Example
Variables	snake_case	`user_count`
Functions	snake_case	`get_user_by_id()`
Classes	PascalCase	`UserService`
Constants	SCREAMING_SNAKE	`MAX_RETRIES`
Private	_prefix	`_internal_method()`

📝 Type Hints (Always Use)

def get_user(user_id: int) -> User | None:
    """Get user by ID."""
    ...

🔐 Security Rules

Never use eval() or exec() with user input
Use parameterized queries for SQL
Validate all external inputs
Use secrets module for tokens, not random

📦 Import Order

Standard library (os, sys, typing)
Third-party (fastapi, pydantic)
Local application imports

⚡ Best Practices

Use context managers (with statements)
Prefer list comprehensions over loops
Use pathlib for file paths
Use dataclasses or Pydantic for data structures

Changes

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.
