These loadouts tell your agent to manage Python with uv: uv add instead of pip install, uv run for every command, and inline or pinned dependencies so a script or test runs the same on any machine. The verifier runs each example with uv, so the commands in the rules are known to work.
Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
discord.py 2 rules for agents: slash commands in cogs, range-limited options, 3-second responses, manual syncing, default intents and offline tests of the payload.
Django rules and a safe-migration skill: migrations checked in CI, two-step destructive changes, N+1 caught with query-count tests, settings from the environment.
DRF rules for agents: explicit serializer fields, querysets scoped to the user, owner set on the server, pagination, and six tests for every endpoint.
Build LLM and agent evals the practitioner way: read real traces first, tally failure categories, then turn each into code-checked regression cases.
Rules and an endpoint skill for FastAPI with uv and Pydantic v2: Annotated dependencies, typed responses, async only when awaited, lifespan, tested routes.
FastAPI on async SQLAlchemy 2.1: per-request AsyncSession, lazy="raise" with eager loads, async Alembic with alembic check, and tests that count queries.
Notebook rules for agents: edit Jupytext-paired .py files instead of JSON, run top to bottom in a fresh kernel, keep outputs out of git with nbstripout, check data first.
Build MCP servers on the official Python SDK v2: MCPServer, Annotated schemas, structured output, ToolError for fixable failures and in-memory Client tests.
Rules for reproducible, single-file Python data scripts with uv and inline dependencies, plus a skill that sanity-checks a dataset before anyone trusts the numbers.
Rules and a command skill for Telegram bots on python-telegram-bot v22: token from the environment, async-safe handlers, testable logic, escaped output, webhook secrets.
