Automate copy-paste and backend wiring work with Codex
A commenter says they use Codex for work that used to involve lots of copy-pasting and backend wiring.
Done withCodex
- What they did
- The commenter uses Codex app and CLI, after setting it up through MCP and signing into ChatGPT, to automate mobile-game asset creation and the backend hookup work that used to require lots of copying and pasting. They give Codex instructions like generating and downloading sprite sheets from a theme file and saving them into a hierarchical assets folder, then leave it to run and check back later.
- How it went
- They say an hour later the folder is filled with the sprites they need and that this removes a tedious part of the job so they can focus on more important work. They do not give output counts or describe failures in their own workflow.
- Worth knowing
- Their practical catch is setup: they mention installing it via MCP and signing into ChatGPT before they could use those Codex CLI workflows.
Try it yourself with Codex
In [repo path], I need to [task, e.g. connect the [frontend form] to the [backend endpoint] / move data between [file A] and [file B]]. I've been doing this by hand with a lot of copy-pasting. Do the repetitive wiring for me, add tests or a quick check that it works, and run them. Finish with a summary of the files you changed, and ask me before deleting any files or changing config outside [scope].
