We use Codex to build our slides. Here's how. @DABrundage, used to spend hours formatting presentations. Now he gives Codex examples of what he wants and has it work directly in Google Slides. His workflow: 1. Make a few reference slides. Create an opening slide, a section br…↗

Every time you let Opus 5.5 run a long task on its own, have it vibe-code a quick 𝗛𝗧𝗠𝗟 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱 like this first. Then give it 𝗮 𝘀𝘂𝗯𝗮𝗴𝗲𝗻𝘁 𝘁𝗵𝗮𝘁 𝗼𝗻𝗹𝘆 𝗯𝘂𝗶𝗹𝗱𝘀 𝗱𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱𝘀: → Name it dashboard-builder, set its effort to medium, and preload…↗

one Opus 5.5 prompt, and now I run around a virtual office managing agents to work on github issues and merge conflicts↗

Jigs very good for tweaking design system values with live previews of how those colours work in the context of specific components and WCAG contrast calculators on screen. So easy to say "show me every component that uses grey 400 and put it in the lab file" → tweak → commit↗

we’re thinking of killing plan mode and using the shift+tab hotkey to adjust effort levels I don’t think the models need plan mode anymore, but if you’re a plan mode diehard would love to get your feedback on why↗

i love prompting for a full walkthrough of a flow i.e here i had it show me all of the steps involved in oauth and found redundant steps, layout shift, and some weird ui state agents don't have to produce slop, they can also help you make great software↗

I asked Opus 5.5 to try a bunch of redesigns of my personal website using my MAX sub, using workflows to iterate and critique. I was really pleased with how it hit the tone I was looking for. Then I asked it to make a trailer with all of its iterations.↗

My job at @every is basically benchmarks-as-a-service now: every.to/also-true-for-…↗

how to improve GPT-6 Astra / Codex's ability to design and code websites I've been using this approach since GPT Image was released, and the results have kept improving with 2 and 2.5 the idea is to have Codex generate visual mockups of the website before building it, whether y…↗

here's how i shipped 2,500 PRs last month to production this was originally supposed to be for Cursor Compile in London. i couldn't make it since i was livestreaming for Grok @Bot Galaxy so i'm making it available for free here on X! watch it on 2x speed, i talk slowly↗

Here's how I run my software factory: 1. During the week, I collect ideas + inspo. 2. On the weekend, I give the list to an agent to rank the best ones. 3. I spin up ~5-10 parallel agents to build POCs. 4. I kill ~60%, iterate on the better ones, and end up with 2-3 solid demos.…↗

my current agents.md that made astra work well still a work in progress, i keep tweaking it try it out and see how it works for you↗

you can also use Jev to cut costs and token usage! make your agents more efficient by compacting shell and large file output before it reaches the LLM passing only necessary tokens to the model and carrying fewer tokens through the rest of the conversation↗

classic @theo being overly confident (but thats why we love you mate) there's a version of this that works remarkably well you should try it!! 1. give all tool results a description input field 2. when its time to compact, instead of summarizing history, drop all inputs and out…↗

Has anyone yet tried to get Astra and Fable to agree on the perfect styleguide? And then host it somewhere with a web mcp.↗

Prompt I use a lot: "how can I pokayoke this so this kind of error never happens again" pokayoke is using simple, low-complexity methods to make a particular kind of mistake impossible to make. classic one would be connector shape: make it impossible to insert "the wrong way".↗

On macOS and wanna see something interesting? Ask your agent: "look at ~/Library/Application Support/Knowledge/knowledgeC.db and tell me some interesting facts" I had no idea this stuff was all getting logged and it can infer a lot about your activity.↗

When you want Astra to review snapshots of your app, ask it to collage them into a contact sheet to minimize the number of image read calls it needs to do. You’ll save a ton of context usage This works for fable too!↗

My blog post about how I manage agents is finally ready. It first explains my bespoke `plans` setup, and then explains how @cursor_ai new Projects feature enabled me |o do so much more. It was the missing piece for me. Check it out: arslan.io/2026/09/11/how…↗

Agents can now automate most repetitive tasks. But running them 24/7 burns countless tokens. Introducing Routines: automated recurring work with AI. Choose an hourly, daily, or weekly schedule. Each run starts with deterministic code and invokes Agent only when reasoning is nee…↗

As promised, my 𝗖𝗵𝗮𝘁𝗚𝗣𝗧 𝗪𝗼𝗿𝗸 onboarding guide. A companion to the tips so far, with more to come! Use it to build a setup around your actual job, whether you’re starting fresh or improving how you already work work-guide.openai.chatgpt.site↗

Pro tip to structure your folders for agents: Stop re-explaining your project every time you open a chat. Give your agent a folder that teaches it how you work. Folder setup: Instructions + project knowledge + incident history + specialized skills • Put your conventions in CLA…↗

I've been trying to use AI for knowledge work (course planning). Here's what seems to work so far: 1. Give each 'deliverable' a Karpathy-style LLM-wiki (for me, a deliverable is a course, or a talk. A sizeable piece of work, more than 1 day's labour) 2. Split the deliverable i…↗

This is amazing. Copy this screenshot into Codex. It can solve most issues with Astra not following instructions. From @pvncher.↗

A few days ago, Anthropic shared this brilliant prompt. I was surprised by how it significantly improved writing with Fable 5.1. Even more surprising, it also improved writing for GPT-5.6 Sol. I have it as a rule everywhere I use AI for editing/writing.↗

I told Astra to check out the Yamauchi no.10 site and then make me something similar for not boring using portfolio companies I've written deep dives on. not bad for ~15 minutes of work!↗

Your input needed: would you use this? This is an early look at how we're thinking about making Claude Code way more extensible. It's a little crazy, and very exciting. More details here: github.com/anthropics/cla…↗

PSA if you're using Claude Code within @get_bb_app: BB uses a local proxy, so Claude Desktop's “load tools when needed” setting doesn’t carry over to BB-launched sessions and Claude loads every MCP tool schema upfront. For me, that meant 167k tokens already filling the context…↗

A prompt to stop Claude from speaking in parseltongue. “Please remove all mannered prose.”↗

I'm taking the working HTML prototype of a first-gen iPod from our last article and turning it into a 1:1 iPod app for iOS, plus a Mac app that controls your Apple Music library. Let’s see how close we can get by morning.↗
