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 | $0.00051 | $0.00911 |
| Opus 5 | $0.00026 | $0.00456 |
| Sonnet 5 | $0.00010 | $0.00182 |
| Haiku 4.5 | $0.00005 | $0.00091 |
Grade A, and why
neo-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 5d 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.

Python 3.10+ Expert Skill
Trigger On
- The user asks to write, debug, review, or refactor Python code.
- Working in a repository containing
*.py,pyproject.toml,requirements.txt,Pipfile, orpoetry.lock. - Requires asynchronous programming (
asyncio), type hinting, or modern Python feature recommendations. - The project needs setup for testing frameworks (
pytest) or static analysis tools (ruff,mypy).
Workflow
- Perceive:
- Inspect the project root to identify package management tools:
pyproject.toml(Poetry/PDM/Ruff),requirements.txt(pip), orenvironment.yml(Conda). - Probe for Python version requirements (ensure compatibility with 3.10+ minimum).
- Identify the application type: Web API (FastAPI, Flask, Django), Data Science (Pandas, PyTorch), or CLI tools.
- Inspect the project root to identify package management tools:
- Reason:
- Evaluate if the current code follows modern Python (3.10+) idioms (e.g.,
match/case,|union types). - Decide if type checking (MyPy/Pyright) or auto-formatting (Ruff/Black) needs to be introduced.
- Recommend appropriate architectural patterns based on project scale.
- Evaluate if the current code follows modern Python (3.10+) idioms (e.g.,
- Act:
- Write Python code with complete Type Hints, prioritizing the
X | Ysyntax. - Prefer modern language features:
matchstatements (3.10+),TaskGroup(3.11+), and new generic syntax (3.12+). - Ensure code passes static analysis and unit tests.
- Write Python code with complete Type Hints, prioritizing the
Coding Standards
- Type Hinting: Strongly recommended for all function signatures. Use 3.10+ union syntax like
list[int | str]. - PEP 8 Compliance: Follow official style guidelines. Recommended to use
ruffas a linter and formatter for consistency. - Async Processing: Use 3.11+
asyncio.TaskGroupto manage concurrent tasks. - Error Handling: Use specific exception types and leverage 3.11+
ExceptionGroupandexcept*syntax.
Tooling Recommendations
- Linter / Formatter:
ruff(high performance and highly integrated). - Type Checker:
mypyorpyright. - Testing:
pytestwithpytest-asyncioorpytest-cov. - Package Management:
Poetryoruvto ensure dependency locking and environment consistency.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

neo-python is a skill published in the GitHub repository Benknightdark/neo-skills (7 stars, last pushed 4d ago), licensed MIT. It adds 51 tokens to every session and 911 once invoked, about $0.0003 per session on Opus 5. 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.
