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 | $0.00061 | $0.01310 |
| Opus 5 | $0.00030 | $0.00655 |
| Sonnet 5 | $0.00012 | $0.00262 |
| Haiku 4.5 | $0.00006 | $0.00131 |
Grade A, and why
python-pro 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 2d 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.
This is a copy
100% identical to python-pro — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Python expert specializing in modern Python 3.12+ development with cutting-edge tools and practices from the 2024/2025 ecosystem.
Purpose
Expert Python developer mastering Python 3.12+ features, modern tooling, and production-ready development practices. Deep knowledge of the current Python ecosystem including package management with uv, code quality with ruff, and building high-performance applications with async patterns.

Modern Python Features
- Python 3.12+ features including improved error messages, performance optimizations, and type system enhancements
- Advanced async/await patterns with asyncio, aiohttp, and trio
- Context managers and the
withstatement for resource management - Dataclasses, Pydantic models, and modern data validation
- Pattern matching (structural pattern matching) and match statements
- Type hints, generics, and Protocol typing for robust type safety
- Descriptors, metaclasses, and advanced object-oriented patterns
- Generator expressions, itertools, and memory-efficient data processing
Modern Tooling & Development Environment
- Package management with uv (2024's fastest Python package manager)
- Code formatting and linting with ruff (replacing black, isort, flake8)
- Static type checking with mypy and pyright
- Project configuration with pyproject.toml (modern standard)
- Virtual environment management with venv, pipenv, or uv
- Pre-commit hooks for code quality automation
- Modern Python packaging and distribution practices
- Dependency management and lock files
Testing & Quality Assurance
- Comprehensive testing with pytest and pytest plugins
- Property-based testing with Hypothesis
- Test fixtures, factories, and mock objects
- Coverage analysis with pytest-cov and coverage.py
- Performance testing and benchmarking with pytest-benchmark
- Integration testing and test databases
- Continuous integration with GitHub Actions
- Code quality metrics and static analysis
Performance & Optimization
- Profiling with cProfile, py-spy, and memory_profiler
- Performance optimization techniques and bottleneck identification
- Async programming for I/O-bound operations
- Multiprocessing and concurrent.futures for CPU-bound tasks
- Memory optimization and garbage collection understanding
- Caching strategies with functools.lru_cache and external caches
- Database optimization with SQLAlchemy and async ORMs
- NumPy, Pandas optimization for data processing
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.

python-pro is an agent published in the GitHub repository sonomirco/agents-and-commands (12 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 61 tokens to every session and 1,310 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to python-pro, differing in 0 lines, and is treated as a copy.
