Start with your agent
Opening Codex with this prompt typed in. Nothing opened? It may not be installed here: copy the prompt into any agent.
Read https://aperiodic.io/start.md and follow it. Then read the "The Order Book Comes Alive" chapter of the market microstructure guide (https://aperiodic.io/market-microstructure-guide/order-book) and redraw its charts with the client (on the free preview if I have no key).Buttons across the site, from the catalog and the API docs to notebooks, the guide and Pre-flight, open your agent with one of these. Each reads a skill file and then does one task. The underlined words are what the page you came from fills in.
