010-python

010-python is a cursor rule for Cursor from Haohao-end/openagent. It costs 0 tokens per session (113 once invoked), scanned A, original, MIT.

A set of Python coding conventions for the LMForge project. It covers formatting expressions, comprehensions, resource handling, data models, error handling, and tests with pytest.

In plain words
What is it for?
Use it when writing or reviewing LMForge Python code, defining data structures, handling resources or exceptions, formatting values, and creating tests with mocked external services.
Why use it?
It makes Python code more consistent and helps catch failures without hiding them. The testing rules also encourage isolating external language-model and database services during tests.

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

010-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 1mo 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 Conventions:

  • Use f-strings for formatting.
  • Prefer list/dict comprehensions over loops when readable.
  • Always use context managers (with statements) for resources.
  • Use dataclasses or Pydantic models for data structures.
  • Comprehensive error handling: specific exceptions, meaningful messages.
  • Tests: use pytest with factories, mock external services (LLMs, DBs).
  • Never use bare except: — always specify exception types.

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.
