Twelve Codex Tricks Power Users Quietly Share

Desktop Codex plus a ChatGPT sub is only half the setup. The rest is harness technique from daily use.

1. Plan credit via ChatGPT MCP — research and plan against the local repo in ChatGPT; execute in Codex on separate quota.
2. Multi-account API pool — round-robin accounts behind a gateway for quota isolation.
3. Excalidraw in the in-app browser — arrows beat a hundred lines when intent is spatial.
4. Parallel imagegen subagents — overnight content factories need fan-out, not serial clicks.
5. Local → remote handoff — start on a laptop, continue on VPS or Mac mini.
6. Design + record/replay plugins — denser UI and reusable procedure memory.
7. Grill-me → PRD — interview requirements before code.
8. Agent kanban — backlog through done with proof of work.
9. Trim the harness — delete ceremony that only burns tokens.
10. Skill warehouse links — one source, many projects.
11. Status surfaces — menu bar so long runs do not own your focus.
12. Multi-tool control center — specialists for search/media; Codex conducts.

Growth now favors people who manage AI systems, not only prompt them.
