Simon Willison reverse-engineers ChatGPT Work and calls out OpenAI for hiding the system prompts and tool descriptions
Willison's August 30 post walks through ChatGPT Work, which shipped July 9 in Cloud and Local variants for $20/month and up. The capability he flags as the real break from Chat is internet-connected code execution: it can clone GitHub repos, install dependencies and use them against the live web, plus a headless Chrome that fills forms, takes screenshots and runs JavaScript against the DOM, a persistent /workspace/scratch filesystem shared across conversations, sub-agents, scheduling, and site deployment to Cloudflare Workers. His complaint is structural, that OpenAI documents features functionally and withholds system prompts and tool definitions, so users are pushed into reverse-engineering.
