A development workflow for building HTML/JS web games with Codex. It pairs small incremental code changes with a Playwright-based test loop that sends input bursts, captures screenshots, and reads game state through a required `window.render_game_to_text` function. Progress is tracked across agent sessions via a `progress.md` file. Manual browser testing of game logic is slow and hard to reproduce, while this skill gives Codex a repeatable, screenshot-verified loop that catches regressions frame by frame.
