Turn the work you figured out with Codex into a method you can run and improve.

​
Two actions

  1. Paste your prompt. Open the dashboard and paste the prompt that already does the job. Method reads it as steps. Each step has its inputs, outputs, and checks. Read the steps and the source review.
  2. Copy one command. The method page shows one command. Run it in a terminal and watch the method run on your laptop:
The open-source SDK runs every step in a fresh Codex session with the tools you already have. It saves the result of each step and checks it before a later step can use it. When a check fails, the run stops and names the step and the check. The quickstart shows both actions and the expert path: convert locally, resume, and recover.

​
What the file holds

A screen recording, reference files, and an example result can also explain the task. Method builds one reusable .method file. Instructions and judgment criteria use plain English. Inputs, outputs, conditions, and checks give the runtime a clear structure. See the method format, checks, and run guide for the details. To create methods from an agent or another application, use the MCP integration.
