OpenAI tells users: stop micromanaging prompts, start with the result

OpenAI just dropped a new prompting guide that reads less like a developer manual and more like advice from a colleague who’s tired of watching you overcomplicate things. The core message? Lead with the outcome you want, not a step-by-step script for getting there. The company consolidated its guidance into a single document aimed at everyday users, stripping away the API parameters and reasoning-effort schemas that dominated its recent GPT-5 and GPT-5.5 developer docs.

The framework rests on four optional building blocks: goal, context, output format, and boundaries. But OpenAI is adamant that a short prompt often works fine. Filling in all four only makes sense for larger tasks. What actually shapes output is specifying a target audience or format. The guide’s own words are blunt: “Describe a process when the process itself matters. Otherwise, leave ChatGPT room to search, compare information, and adjust its approach.” That’s a shift away from the elaborate prompt engineering that’s become a cottage industry.

Constraints, not scripts. That’s the philosophy. The guide recommends one or two hard rules to block unwanted behavior — things like “Keep the approved dates and budget figures unchanged” or “Prepare the message as a draft. Don’t send it.” The same minimalism applies to context: only attach files that will genuinely change the answer. For high-stakes work, OpenAI suggests asking ChatGPT to verify its own output, checking whether every action item has an owner and deadline. The guide also draws a sharp line between Chat for quick tasks and the new “Work” feature — built on Codex and GPT-5.6 — which handles multi-source projects that produce finished Excel or Word documents.

Codex itself gets some interesting new controls. Users can “steer” a task mid-run by adding a message that redirects the current operation, or queue one for the next run. Two slash commands stand out: “/plan” tells Codex to analyze code and propose an approach before touching anything, while “/goal” sets a higher-level objective it follows across multiple steps. Everything runs in a sandbox that restricts file and network access unless the user approves otherwise. For reviews, “/review” works locally or via GitHub comment with optional focus areas like security vulnerabilities. The whole package reflects a product convergence — Chat and Codex are becoming one thing, and the advice for using them is finally catching up.
