How to use /goal in Codex to ship huge features

love the video and the format (half you/half comp)

Thanks! it's an iphone app

@BenSyne Which app? Cool idea!

@BenSyne mixcam

Love the split format! Keep going

Thanks man

Same energy with Claude Code on my end. The shift is real... what used to take me a weekend to figure out now ships in one evening session. The bottleneck moved from 'can I build this' to 'should I build this.'

i've basically never used cc. cursor -> amp -> devin + codex

Can you expand on your claude design workflow. Haven't gotten mine dialed in yet.

Is the actual /goal you’re using something straightforward like “satisfy all acceptance criteria in prd.md”?

Yes

Great vid, woukd love to see u starting yt videos. Question to Claude design, do you do every single screen of your app/ new feature in Claude design or just few and let codex do the rest?

how are you liking Claude design vs figma?

i don't use figma

Did you switch to ultrawide monitor recently? Realized having more real estate for multiple agents in parallel was a huge unlock 😂

yup. dell 52 is just bliss

haha, missed these vids 😄

What effort is Codex working at for a large build like this? I’m always between hard and extra hard, but I find the latter almost overthinking sometimes.

high

cool to see your process! Thanks for sharing 🤙

thx for watching

Liked the Mermaid code callout. We use that extensively on and it’s very versatile and effective.

V interesting. Do you find the Mermaid diagrams help codex deliver the feature correctly? Do you inspect the mermaid charts yourself?

Mermaid charts definitely help me. I'm not 100% sure how much they help the model, but I think the clarity is probably always good.

So many great tips. Thanks for sharing. Did you use Figma or other design assets to build the design system that Claude Design uses? I'm wondering how well Claude Design handles starting from scratch.

So I paid a designer for the initial branding and design system, and then Claude Design is able to pretty much use it for UI. I would say it's not good enough for designing really great landing pages. I think humans still win on that.

You’re a mind reader because I’m building a landing page. Guess I’ll be spending more time in Figma after building out some design system assets. I might try giving it some design references and see how it does.

GPT5.5 is a work horse once you get it aligned. Geez. we are cooking over here. Like literally my laptop is hot.

i'm loving this model

I need to go to bed.

Do you use ai to write your prd’s too?

What display are you using? It's fire

@grok summarize this for everyone, pls and thank you.

What are you building?

I vibed my way to a private media aggregator by telling Claude Code what to do. Like very few minutes for weeks. When I learnt to say. 'heres the goal, test, measure and iterate every 5 minutes' my life changed.

This workflow is a game changer for tackling complex builds.

/goal is underrated for big feature work. giving the agent a north star vs a single task changes how it sequences steps. watched it make decisions mid-run I wouldn't have thought to specify explicitly.

Curiosity: What size is your monitor?

Super helpful, thanks for sharing. Claude design is amazing.

`/goal` is the useful primitive here: it turns a huge feature from one long prompt into a stateful contract the agent can keep checking against.

/goal is just a requirements doc that actually gets read. first time in my career that's happened.

Are you using Devin for the day-to-day type of stuff?

Learned a lot in 6 minutes. Very cool / thank you. What is that ultra-wide monitor you have? The more AI I'm using, the more screen real estate I need😅

what are you using to get the split format videos? that’s sick!

How is a good way to get to the detailed plan for the /goal feature?

Codex真的顶

Perhaps I missed that moment in the video, but where is AMP in the process? Thanks for sharing!

Can you demo a walk through?
