Need help deploying python?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/harleybartles-python
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

# Python Use this skill for idiomatic Python guidance across language patterns, concurrency, testing, and type safety. ## When to Use - Writing or reviewing Python code. - Choosing between async/await, threading, or synchronous execution. - Writing tests, handling type annotations, or profiling a hot path. ## Core Pattern 1. Prefer explicit over implicit: write readable code, avoid surprise imports, and document public APIs. 2. Use `asyncio` for I/O-bound concurrency; use `concurrent.futures` or multiprocessing for CPU-bound work. 3. Structure tests with `pytest`, fixtures for shared state, and parametrization for data-driven cases. 4. Add type hints where they clarify contracts; run `mypy` or a type checker in CI. 5. Profile before optimizing; `cProfile` and `line_profiler` identify real bottlenecks. ## Common Mistakes - Mixing `async` and sync I/O in the same loop. → Await async libraries or run blocking calls in executors. - Overusing mocks and testing implementation instead of behavior. → Mock boundaries, not internals. - Ignoring type checker errors. → Treat `mypy` failures like test failures. Load `references/operational-guidance.md` for deeper coverage of asyncio, pytest, and typing patterns.
