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 | $0.00068 | $0.03551 |
| Opus 5 | $0.00034 | $0.01775 |
| Sonnet 5 | $0.00014 | $0.00710 |
| Haiku 4.5 | $0.00007 | $0.00355 |
Grade A, and why
python-programming-expert 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.

The opening of the file, as written. The whole thing — 409 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Python Programming Expert (3.14 Edition)
English
Orchestration & Integration
Connects and orchestrates with relevant domain skills like brainstorming, zero-to-prod-orchestrator, and project-context-mapper to ensure cohesive execution.
Description
Expert-level Python development guidance for Python 3.13 / 3.14+ covering JIT compilation, free-threaded (no-GIL) mode, modern type safety patterns, async architecture, and the full production stack: FastAPI 0.115+, Pydantic v2, SQLAlchemy 2.x / SQLModel, uv, Ruff, and pytest-asyncio.
Trigger Conditions
- Writing Python 3.13+ / 3.14+ applications or services.
- Building FastAPI 0.115+ REST APIs, Django 5.x, or Litestar web services.
- Managing Python projects with the
uvpackage manager. - Implementing async/await patterns with
asyncio.TaskGroupor structured concurrency. - Writing type-safe Python with Pydantic v2 and modern generics (PEP 695/696).
- Setting up Ruff for linting + formatting; pytest with
pytest-asynciofor testing. - Building AI backends integrating with LLM APIs (OpenAI, Anthropic, Google GenAI).
Python Version Matrix (2026)
| Version | Status | Key Feature |
|---|---|---|
| Python 3.14 | Latest (Oct 2025) | PEP 696 defaults, improved JIT, @ on types |
| Python 3.13 | Stable LTS | JIT compiler, free-threaded mode (no GIL) |
| Python 3.12 | Supported | PEP 695 generics, type alias statement |
| Python 3.11 | Security only | asyncio.TaskGroup, ExceptionGroup |
Modern Python Toolchain (2026)
uv — The Standard Package Manager
Replace pip, pip-tools, virtualenv, pyenv, and poetry entirely with uv (written in Rust — 10-100x faster):
# Create project
uv init my-api
cd my-api
# Add runtime dependencies
uv add fastapi pydantic httpx sqlalchemy[asyncio]
# Add dev dependencies
uv add --dev pytest pytest-asyncio ruff mypy httpx
# Run scripts (no activation needed)
uv run python main.py
uv run pytest
uv run fastapi dev main.py # Hot reload dev server
# Pin exact Python version
uv python pin 3.13
# Sync all environments
uv sync
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-programming-expert is a skill published in the GitHub repository roedyrustam/vibes-plug (49 stars, last pushed 2d ago), licensed MIT. It adds 68 tokens to every session and 3,551 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 2026-09-03.

Keep TypeScript and Python SDK behavior, generated client usage, public API naming, and docs examples aligned. Use when a change affects both SDKs, when generated client pins move, when comparing TS/Python behavior, or when a backend API contract changed. Do not use for single-language internal-only changes.
