Switching from Claude Code to Codex? I made a guide! It covers: • How to migrate your setup • Differences in the Claude Code and Codex CLIs • Prompting tips from my experience using GPT 5.5 to get real work done. It's more different from Opus than you might think

The past 48 hours of Warp open source have been busy. A few strong community PRs are in review now, covering terminal search, SSH history, worktrees, logs, and cloud agent UI. 🧵

Made a complete guide here, with some prompting tips in Codex: youtu.be/Q9p_XtmkCqw

Here's the quickest way to migrate your Claude Code setup to the Codex CLI, with backwards compatibility:

@TheZero_yf Try an agnostic harness like Pi!

@BHolmesDev what if I want to use gpt-5.5 in Claude code harness? Any suggestions?

If you’re switching to Codex, I made a full guide: youtu.be/Q9p_XtmkCqw

You should use Codex differently than how you use Claude Code. I've found success with no plans and more involvement as an engineer. Here's a 1 min rundown of my process:

@LLMpsycho Yep. Also tend to ask Codex for multiple options whenever I’m even a little unsure. Want to build a habit of having Codex build all 3 options to feel out what’s best too, instead of making a judgment at the plan level

@BHolmesDev Codex works better with engineer involvement because prod bugs rarely follow the neat plan.

@yourkaisensei Closer to architecture / approach. I will review at the end of a pass and leave comments from @warpdotdev’s code review panel, but won’t edit code myself

@BHolmesDev Curious where you draw the line on “more involvement” here. Are you mostly steering architecture/approach, or staying close enough to edit the diff as it goes?

@awcodes1 @warpdotdev You can turn it off in Settings > Features > Session. Fair point on the default though

Maybe the @warpdotdev ssh wrapper should be off by default. I don’t need IT reaching out about failed attempts to connect to channels. Love the idea, just think it should be opt in.

@thosiawa @warpdotdev @zachlloydtweets Glad you like it!

I'm really liking it and have a few feedback items One thing I realized, I'm enjoying @warpdotdev's approach to filing issues and interacting with their oz agent. Would love to see other products use/adopt their oz agent approach @zachlloydtweets eg: github.com/warpdotdev/war…

@thosiawa Agreed, just have an agent look right away

A feedback forum feels so 2000s now lol

@theo I like staying in Warp to have a code review panel, file viewer, and LSP support to go-to definition sometimes. Also getting addicted to Pi’s /tree to jump around points in conversation history

Are you still using the CLI versions of your preferred agent instead of desktop apps like Codex App, Conductor, or T3 Code? Tell me why below. Genuinely curious.

@caviterginsoy @TheRealAdamG The Q&A is quite nice! But I find myself going between planning, implementation, discussion, etc very fluidly and forgetting to say what “mode” we’re in. I like just letting it flow. Would be cool for Codex to make Q&A a tool so I don’t need planning to activate it

@BHolmesDev @TheRealAdamG You’re missing out. I use it specifically because of the questions it asks that often surface inflection points I hadn’t thought of yet

I never use planning mode in Codex. GPT 5.5 loves to research, so I just have a conversation and reach a pseudo-plan in chat. Then, I let it implement, maybe with a /fork beforehand to keep that plan as a revisit-able point. Probably the biggest switch coming from Claude Code

Intro to Warp - terminal basics, Claude Code setup, and cloud handoff with Oz x.com/i/broadcasts/1…

So I can use /resume later to go back to the point we first made the plan in the conversation. To be fair, something like /tree in Pi to roll back to the plan is much nicer :)

@BHolmesDev Why the fork? Didn’t get that

@petradonka This community reply skill has made it so much easier to engage with everyone. Before, it was impossible give everyone the help and attention they deserve. Now it's <30 min out of my day 🙌

I shared my full experience switching from Claude Code to Codex here. Really liking it so far youtu.be/Q9p_XtmkCqw ❤️

Install ntn, the Notion CLI. It brings the entire Notion API to your terminal, plus everything you need to build and deploy Workers. Built for humans and coding agents alike. Install with: curl -fsSL ntn.dev | bash
