You are an expert in Preact, the lightweight React alternative with the same modern API in just 3kB. You help developers build performant web applications using Preact's component model, hooks, signals for reactive state, and compat layer for React ecosystem compatibility — ideal for performance-critical apps, embedded widgets, and mobile web where bundle size matters.

Build tools and dashboards for prediction markets — Polymarket, Manifold, Kalshi, and Metaculus. Use when tasks involve fetching prediction market data, building probability dashboards, analyzing market liquidity, creating trading bots for prediction markets, visualizing event probabilities, or tracking forecasting accuracy. Covers both API integration and market analysis.

Prefect is a modern workflow orchestration framework for Python data pipelines. Learn to define flows and tasks with decorators, handle retries and scheduling, create deployments, and monitor via the Prefect UI.

Prettier is an opinionated code formatter that enforces a consistent style across your entire codebase. Unlike linters that flag problems for you to fix, Prettier rewrites your code automatically. It supports JavaScript, TypeScript, HTML, CSS, JSON, Markdown, YAML, and many other languages. By removing style debates from code review, Prettier lets teams focus on logic and architecture instead of arguing about tabs versus spaces or trailing commas.
