Codex Goals: A 6-Component Framework for Autonomous Agent Tasks
Summary
Claire Vo (ChatPRD) walks through Codex /goal in depth with real examples: a 5h45m autonomous run eliminating hundreds of Sentry errors, and a 4-hour job that cleaned 3,900 emails down to 68. The six-component framework for writing Goals that work: (1) outcome — what should be true when done, (2) verification — how to test it, (3) constraints — what can't regress, (4) boundaries — what tools/files to use, (5) iteration policy — how to decide what to try next, (6) stopping conditions — when to ask for help. Goals differ from prompts fundamentally: a prompt says what to do; a Goal describes what a good outcome looks like and how to verify it.
Why this signal
Liftable 6-part framework directly usable for structuring agent prompts on Thomas Engineering projects. The Sentry example maps well to any codebase quality initiative. Cost data (6M tokens for email cleanup) is useful for AI budget conversations.
