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.

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 | $0.00000 | $0.00218 |
| Opus 5 | $0.00000 | $0.00109 |
| Sonnet 5 | $0.00000 | $0.00044 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
2-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 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
Type Annotations:
- Type every function arguments with type hints
- Avoid using Any
- Use
Type | Nonefor nullable types, instead ofOptional - Use
dictandlistfor type hints, instead oftyping.Listortyping.Dict
Error Handling:
- Use specific exceptions for error handling
- Avoid catching broad exceptions like Exception
Code Structure:
- Use dataclasses for simple data structures
- Prefer NamedTuple for immutable data structures
- Put classes, error and enums in their own standalone files
- Put non-public functions and methods at the bottom of the file
- Prefix non-public functions and methods by an underscore (
_)
Enumerations:
- Use Enum for enumerations
- Define enum values explicitly
Linting and Formatting:
- Follow PEP 8 for code style
- Use Ruff with
uvfor formatting and linting
Generics:
- Use TypeVar for generic types
- Use descriptive type parameter names
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.

2-python is a cursor rule published in the GitHub repository cmnemoi/cursor-rules (2 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 218 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.
