Use when the task is Python itself, in any framework or none: PEP 695 generics, mypy --strict typing, dataclass/Protocol/TypedDict/Enum choices, asyncio.TaskGroup, stdlib idioms, src/ layout + pyproject.toml with uv, ruff+mypy+pytest gate. NOT a FastAPI/ASGI service (that is fastapi), NOT a deep pytest suite (that is testing-py).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Modern Python at the language level Write, review, modernize, type, and package Python that reads like a typed, flat-control-flow, stdlib-first program whose dependencies and tooling all live in one `pyproject.toml`. Types are part of the design, not decoration; the stdlib is large and you reach for it before a dependency; correctness is `ruff` + a type checker + `pytest` in one gate. Targets **Python 3.12+ (floor) / 3.14 (current**, released 7 Oct 2025): PEP 695 inline type parameters (`class Box[T]:`, `type Alias = ...`), `asyncio.TaskGroup`, and — in 3.14 — deferred annotation evaluation by default (PEP 649/749, no more `from __future__ import annotations`), PEP 750 template strings (`t"..."`), and `compression.zstd`. Tooling pins: **uv 0.11** (project + package manager), **ruff 0.15** (lint + format), **mypy 1.20 `--strict`** (or Astral's `ty`, still preview — default to mypy), **pytest 8**. ## Scope — what this skill delegates - Building a FastAPI / ASGI service (routes, Pydantic models, SQLAlchemy, uvicorn) -> [`fastapi`](../fastapi/SKILL.md). That skill owns the service shape; this one owns the language it is written in. …

How to install
mdr add ericrisco/rsc-harness/python@sha256:6938dd0d15dcd602The line at the top of this page pins the label git:20260729.3ecb845, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
