vibe-coding-ai-rules: Instructions file for GitHub Copilot

ide-specific/github-copilot/.github/instructions/python.instructions.md

vibe-coding-ai-rules python.instructions.md is an instructions file for GitHub Copilot from obviousworks/vibe-coding-ai-rules. It costs 164 tokens per session, scanned A, original, MIT.

A set of Python coding rules covering type hints, data validation, asynchronous input and output, code style, and error handling. Python is a programming language commonly used for web services, automation, and data work.

In plain words
What is it for?
Add typed function signatures, validate data with Pydantic, run I/O asynchronously, use modern Python structures and pathlib, and define specific exceptions.
Why use it?
It provides consistent patterns for writing clearer Python code and handling invalid data and failures explicitly.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is obviousworks/vibe-coding-ai-rules's own configuration. It tells GitHub Copilot how to work on vibe-coding-ai-rules itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vibe-coding-ai-rules configures →

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

vibe-coding-ai-rules 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 2mo 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

Python Patterns

Type Hints

  • Required for all function signatures (params + return type)
  • Use Pydantic models for data validation
  • Use TypeVar and Generic for reusable types

Async

  • Use async/await for all I/O operations
  • Use asyncio.gather() for concurrent operations
  • Never mix sync and async code in hot paths

Style

  • Follow PEP 8 strictly
  • Use structural pattern matching (Python 3.10+) over complex if/else
  • Prefer dataclasses or Pydantic over plain dicts
  • Use pathlib over os.path

Error Handling

  • Use specific exception types (never bare except)
  • Create custom exceptions for domain errors
  • Use contextlib for resource management
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.
