Optional Add-Ons
Two things that make Codex noticeably more useful for ads work. Neither is required — the setup above is complete without them.Let Codex use your computer
With Computer use on, Codex can work inside your other apps, not just call Adspirer’s tools: open Ads Manager or Merchant Center in Chrome to check something the API doesn’t expose, read a budget sheet in Excel, or drop a report into one. Codex asks before it touches an app, and you can set Always allow per app once you trust it.Turn on Computer use

Settings → Computer use — Any App, Google Chrome, and Microsoft Excel switched on
Turn on Computer history (macOS)

Settings → Computer history, with Permissions for including or excluding apps and websites
Install your Expert Kit
The Prompt Engineering Playbook generates an Expert Kit from one of your ad accounts: an agent with account-specific instructions, a skill, a prompt book graded Beginner → Expert, and reference files on the account and on working with Adspirer. It’s a paid add-on (included on annual plans) — pricing and what’s inside are on that page. On Codex Desktop you don’t copy files anywhere: you hand the folder to Codex.Download the kit
google-ads-expert-<brand>/, containing:Hand it to Codex
AGENTS.md inside the skill rather than at the project root, so it doesn’t override instructions you already have. Your Adspirer sign-in is untouched.Start a new task with the expert
