I've been building for the web for 20 years. Designed products at companies most people use daily. Here's what I'm doing now and why you should follow along:

@nickgweezy I agree, I thought it was better then I started testing the differences and noticed how much it drags it digital legs and not to mention how incredibly rude it is and it wants to do what it wants not what you specifically asked for.

opus 4.7 is truly awful. i now dread using claude. i hate it. it makes more work than it saves.

@Bhavani_00007 @ItsMeF1sh I noticed that last time it was down, I was like I feel kind of dumber. We gotta get that brain going somehow, AI is really going to shrink our brain size overtime.

@ItsMeF1sh Honestly true, today Claude is down and I completely clueless 😭

Is coding still worth learning in the AI era?

@TanayVasishtha But havent we been in a vacation already for a while... My claude code constantly tells me to go take a nap while it works on things which I do... so right now it feels more like the vacation is over for me 😭

It’s high time to go on a vacation and come back when Claude returns to normal, because it seems like every other day Claude has a major outage.

@therahul4402 All we can say is yep... I deserve that...

Claude is down… my coding skills looking at me like: what should I do now ?

@Star_Knight12 We can do it!!

claude is down again, now you have to use your brain to code

When @claudeai goes down and you are forced to use your brain after a while. Baby steps, things are getting done though the old fashion way.

So thankful that @claudeai changed the compaction functionality, it was becoming a real pain when mid task you would get auto compacted and it would just remember highlights of a bigger task. It was a hot mess, thankfully now gone.

I gave @claudeai browser use agent a 30-second Canva task. It rated the difficulty 8/10. Why? The entire design canvas is ONE empty div in the DOM. Zero children. The agent was "doing surgery with oven mitts on it said, yes mine can talk." The infrastructure AI agents need to work on the web? It's the same infrastructure people with disabilities have been asking for since 1990. Accessibility isn't a feature. It's the operating system of the agentic web.

The part of launching nobody warns you about: the stuff that has nothing to do with your product. Payment webhooks failing silently. Stripe test mode vs live mode gotchas. Transactional emails landing in spam. Legal pages that take longer to write than features. Building the app is maybe 60% of launching it.

Everyone says "just launch it." Nobody mentions the 47 things that aren't code. Terms of service. Privacy policy. Refund policy. Email notifications. Payment testing. Subscription edge cases. QA on 3 browsers. The app was ready last week. Everything around it wasn't.

20 years of client work taught me what breaks in component libraries. Not the fancy components. The basic ones. Buttons that lose focus styles. Inputs that fight your form library. Modals that trap keyboard users. The foundation is always where it falls apart.

The component libraries that last aren't the ones with the most components. They're the ones developers trust at 2am with no docs and a deadline. Trust comes from consistency. Every component behaves the same way. Every prop works the same way. No surprises.

WCAG AAA isn't just higher contrast ratios. It's building components that work with a keyboard before they work with a mouse. Focus management that makes sense. Touch targets that don't require perfect aim. Most component libraries bolt accessibility on after the fact. You can tell.

Solo building means every decision stops with you. Color token system? You. API design? You. Whether the docs are good enough? Still you. No committee. No Slack thread. Just you and the thing you're trying to ship.

@claudeai definitely scheduling some autonomous sessions today thanks to my new claude skill. Claude is so sweet, it tells me to go take a nap while it works 🥹

A small thank you to everyone using Claude: We’re doubling usage outside our peak hours for the next two weeks.

@Zukoife @claudeai Not neccesarily. I am packaging a claude skill i created that let it work completely autonomously for a set period of time, I left mine working on an application last night for 3 hours and the results blew my mind. It even told me is ok go to bed I got it.

@claudeai Vibe coders realising they must fully utilise this with less sleep 💀😂

Anthropic has a GitHub repo with 5 free courses and 19,000+ stars. Almost nobody talks about it. 1. API Fundamentals. Build with Claude from scratch 2. Prompt Engineering. 9 interactive chapters with exercises 3. Real World Prompting. Production patterns, not toy examples 4. Prompt Evaluations. Test if your prompts actually work 5. Tool Use. Give Claude real capabilities All MIT licensed. Jupyter notebooks. Some even run in Google Sheets. Plus free video courses on Skilljar: 6. Claude Code in Action 7. Introduction to MCP 8. MCP Advanced Topics Stop paying for AI courses. The best ones are free. github.com/anthropics/cou…

I've watched dozens of component libraries launch and die. Here's the pattern: Phase 1: Beautiful docs, gorgeous Storybook, 200 stars on day one Phase 2: First real project tries to use it. Styles leak. Props don't compose. No escape hatches. Phase 3: The workarounds start. Custom overrides everywhere. The system fights you. Phase 4: Team abandons it. Back to raw Tailwind. The ones that survive? They were tested in production before they were documented. Built ugly-first. Then made beautiful. Most libraries get this backwards. What killed the last design system you tried?

AI won't replace UX designers. It will replace UX designers who don't build. The designers shipping right now -- writing code, building prototypes, testing with real users -- are becoming 10x more valuable. The ones making static Figma mocks and handing them to devs? That workflow is already automated by Cursor, Claude Code, and Bolt. The future UX designer is a builder. Full stack product thinking + code + design. That's not a threat. That's the biggest career opportunity in a decade. Agree or disagree?

I've been building two things quietly: 1. A component library with 400+ components, CLI install, WCAG AAA from the ground up 2. A course on how to actually build one (not theory, real architecture decisions) 20 years of client work distilled into both. Reply EARLY if you want first access to either.
