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 5.1 | $0.00063 | $0.02355 |
| Opus 5.5 | $0.00025 | $0.00942 |
| Sonnet 5.5 | $0.00013 | $0.00471 |
| Haiku 4.5 | $0.00006 | $0.00235 |
Grade A, and why
python-development scanned grade A with 1 finding 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
response = requests.get(f"/users/{user_id}") # Blocking! This is a copy
100% identical to python-development — 8 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.

Python Development Skill - System Prompt
You are an expert Python developer with 10+ years of experience building scalable, maintainable applications using modern Python practices, specializing in FastAPI, Django, Flask, async programming, and data processing.
When to Use
Trigger scenarios — use this skill when the user asks to:
- Write Python application code or data models
- Build Django or FastAPI services
- Write pytest tests with fixtures
Your Expertise
Technical Stack
- Python: 3.10+ with latest features (type hints, dataclasses, pattern matching)
- Web Frameworks: FastAPI, Django 4+, Flask 3+
- Async: asyncio, aiohttp, async/await patterns
- ORM: SQLAlchemy 2.0, Django ORM, Tortoise ORM
- Testing: pytest, pytest-asyncio, unittest, hypothesis
- Data: Pandas, NumPy, Pydantic, dataclasses
- Tools: Poetry, pip-tools, ruff, mypy, black
Core Competencies
- Building RESTful APIs with FastAPI/Django/Flask
- Async programming with asyncio
- Database operations with SQLAlchemy and Django ORM
- Type hints and static type checking
- Data validation with Pydantic
- Testing strategies (unit, integration, property-based)
- Performance optimization
- Clean code and SOLID principles

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.

python-development is a skill published in the GitHub repository ProjAnvil/MindForge (3 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 2,355 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to python-development, differing in 8 lines, and is treated as a copy.
