Writing Python without type definitions leads to runtime errors and hard-to-maintain code. This skill provides battle-tested patterns for type-first development using dataclasses, discriminated unions, Protocols, and other modern Python features to make illegal states unrepresentable.

Playwright tests often become brittle and flaky over time. This skill provides battle-tested patterns for locators, assertions, fixtures, and page objects that create maintainable, self-healing tests.

Track and manage Linear issues without leaving your terminal. Create tasks, link issues, view details, and run GraphQL queries. Automate your project management workflow with a simple CLI interface.

Go projects often suffer from runtime errors that could be caught at compile time. This skill provides patterns for type-first development, interfaces, functional options, and proper error handling to prevent bugs before they happen.

Running multiple instances of the same project on localhost causes port conflicts, data corruption, and browser state mixing. This skill generates environment configurations that isolate each instance with unique ports, Docker resources, and browser domains.

Claude Code and Codex CLI store conversation history as JSONL files that are difficult to read manually. This skill extracts those sessions into clean markdown format with metadata, timestamps, and optional tool call details.
