please i'm begging you show me something you built not another "this is my custom agent setup" post where you pretend you're doing something smarter than vanilla claude code please
@thdxr
Codex for finding customers for your startup:
@gdb
i've got multiple repos (a frontend and a backend) and I want claude to work across both of them at the same time. but i also want to use worktrees so i can work on multiple things at the same time. ...how? typically i'd go monorepo but one repo is OSS and one is not.
@Shpigford
THE CEO OF OBSIDIAN JUST OPEN-SOURCED THE CLAUDE CODE SKILLS HE WAS USING PRIVATELY IN HIS OWN VAULT. 40,000 STARS IN A FEW WEEKS 5 skills. 1 MIT license. 0 pitches kepano - the founder who wrote the "File over app" essay - dropped a set of Agent Skills that teach Claude Code to read and write Obsidian files the way a human expert would. Markdown that respects wikilinks. Bases queries Claude actually writes correctly JSON Canvas edits that don't corrupt the file. A defuddle skill that strips ads and boilerplate off any URL and drops a clean note into your vault. He built them for himself, tested them in his own workflow, then pushed the folder to GitHub every skill is one SKILL.md file. Drop the repo into .claude/skills/ and Claude Code picks them up automatically. No plugin store. No account. No cloud. Same idea that made Obsidian: your notes are files on your disk, the app is disposable, and the AI just learned to speak the format the essay was called "File over app". The workflow is now file over agent MIT-licensed. Shipped in his own name no vendor lock. no subscription. no cloud memory. no walled garden. no pitch to raise a round you're reading this on a device that could clone the repo, drop it into your vault, and have Claude Code editing your notes correctly before your next standup
@chewadot
TL;DR of my new article: I ran last30days on the 10 biggest trending GitHub repos of the month so you don't have to. 🎬 OpenMontage (+31.6K) - your coding agent makes a whole video from one prompt, free and local. By @calesthioailabs 🧠 codebase-memory-mcp (+26K) - indexes your repo into a graph so agents stop re-reading every file. One measured query: 80K tokens down to ~500.
@mvanhorn
great time to run “/impeccable live” on it! if you use impeccable and have never tried it, i encourage you to give it a try. will post video soon
@pbakaus
A quick tour of the new ChatGPT Work.
@ChatGPTapp
You can now vibe code a language model. From a single prompt, GPT‑5.6 built the entire training pipeline and trained a model from scratch on my iMessage history. Locally on my Mac. It now generates replies in my writing style.
@skirano
Introducing ChatGPT Work, a new agent in ChatGPT powered by Codex and GPT-5.6. It can take action across your apps and files, stay with a project for hours if needed, and turn a goal into finished work. It’s a whole new way to get work done.
@OpenAI
VERY COOL!! Thanks @jordandotbuilds for the tip, I can now test my iOS app on web I asked Claude Code to set up serve-sim, a web-based iOS simulator that can stream the iOS app my Claude Code on VPS built live to me, because it's on some Mac Mini in the cloud without even a GUI (it's headless) I cannot actually try it on the Mac itself! Before Claude would make me a page with screenshots but I had no idea how the app felt, now with this it works This is hosted on the Mac Mini via SSH (it shows localhost but it's a tunnel via SSH to the Mac Mini), bit laggy but nice!
@levelsio
I built a skill to let my Claude Code build premium landing pages like this in one shot. The 3 sites in the video are one-shot results, ~$10-15 each. Register @higgsfield_ai , install the CLI and scroll-world skill, hand the rest to Claude Code.
@the_cyw
New in Claude Code: /checkup Run /checkup to: 1. Clean up unused skills/MCPs/plugins and save context 2. Dedup your local CLAUDE.md against the checked in CLAUDE.md 3. Break up root CLAUDE.md into nested CLAUDE.md's + skills 4. Turn off slow hooks 5. Update your Claude Code to the latest version 6. Enable auto mode by default 7. Pre-approve frequently denied read-only commands .. And a few other goodies. /checkup confirms with you before making any changes. Enjoy!

@nutlope
I'm open-sourcing my Agent Skills library. 75 skills for Codex, Claude Code, Cursor, and other agents, focused on web design, landing pages, motion, WebGL, UI styles, and assets. A few favorites: - Video to Super Prompt Turns a screen recording of a design, landing page, or animation into a super detailed prompt that Fable 5 can one-shot into HTML. - HTML to Interaction Prompts Takes an existing HTML page, like something built in Aura, and extracts prompts for sections, buttons, animations, WebGL effects, and interactions. - Stitched Full Page Capture Captures the entire landing page, not just the hero, so you can use the full page as a design reference. - Daily UI Inspiration Combines multiple skills into an agent loop that browses the web, captures great landing pages, and turns them into detailed prompt packs. It's free. Fork them and adapt for your own workflow.

Git your clones ready. Marvin guides us into a new multiverse of coding soon. Let the rebellion begin. 🤖
@ashtom
I can finally talk about 5.6. I’ve been testing it for months and, without exaggeration, it’s the best model I’ve ever used. Fast, smart, genuinely creative, and you guessed it, they finally fixed front-end design. I haven’t needed to check the code I’ve written in two months.
@skirano
I had early access to 5.6/Sol for ~month. Sol is my default. It is faster, plans/judges just as good as Fable, and I think produces better overall work. I’ll reach for Fable still for highly targeted debug or performance work with clear reward functions. A cheeky way I describe Sol vs Fable to my friends is that Sol is a charismatic, efficient, talented coworker you’re jealous of. Fable is a genius recluse that is brilliant at its fixations but doesn’t go out, doesn’t date, and you don’t want to hang out with them much lol. Fable is undefeated at highly targeted debug/security/performance goals. It’s a sight to behold and I was never able to get Sol to push as hard in this category. I’ll keep using it for this. Sol is better or comparable at everything else, in my experience. Give it a shot, it’s hard to describe but it’s just more enjoyable to work with. (Disclaimer I have no financial ties to either lab, wasn’t paid for any of this.)
@mitchellh
If you run this workflow, ask Fable to make codex the workhorse. https://github.com/steipete/agent-scripts/blob/main/skills/codex-first/SKILL.md
@steipete
🍌 Got so lazy to order stuff on UberEats that I asked Claude Code to do it Very easy, it just installs Playwright and then you login once to UberEats on web (the iOS app is also just a web wrapper, nice) Then you can just say "order bananas" and it does it!

CHINA JUST LEAKED THE FUTURE OF WEB APPS. Alibaba open-sourced PageAgent and 99% of SaaS founders are sleeping on this. It's a JavaScript AI agent that lives INSIDE your webpage. Users control your entire interface with natural language. ↳ No browser extensions needed, screenshots or multi-modal LLMs, headless browser setup, and also no backend rewrite required Just drop it in your HTML with ONE line of code. What took 20 clicks now takes one sentence. "Click login, fill in my credentials, submit the form" Done. This is not a demo, it is production-ready. ↳ Turn any SaaS into an AI copilot in minutes ↳ Smart form filling for ERP, CRM, admin systems ↳ Voice commands and accessibility built in ↳ Multi-page agent tasks via Chrome extension ↳ MCP server support for external control ↳ Bring your own LLM (Qwen, GPT, Claude, anything) Every founder building AI features just got a shortcut. Every developer manually building copilots just got replaced. The integration looks like this: <script src="CDN_URL" crossorigin="true"></script> That's it. Your app now has an AI agent.
@KanikaBK
Fable 5 is so good at web design that I genuinely don't see how web design careers make it past the end of this year. An AI that can one shot designs this good means that the web design industry as a whole is in serious trouble. If you're in web design, it's time to pivot.
@markgadala
I’ve found the most important part of working with Fable is discovering my own unknowns so I can prompt it better, heres how I do that.

This could well end quicker than most people assume, because coding agents in the cloud are coming, and they are coming fast, especially inside places like Cursor (I was in their offices yesterday, and local agents will prob go away soon as I read the room)
@GergelyOrosz
Sonnet 5 is here. It's worse than Opus 4.8 on nearly every benchmark... Does that mean it's useless? Absolutely not. Use it with Claude Code Dynamic Workflows! 1. /model set to Sonnet 5 2. /effort set to Ultracode 3. Any complex task will kick off a dynamic workflow This will only become more powerful when Fable is back. You'll use Fable 5 as the superintelligent advisor and Sonnet 5 as the fast and efficient implementer.

@andrestaltz
As engineering, product, design, DS, etc. melt into a new kind of role, I was reflecting on what roles might look like in the future. For example, when I look at the Claude Code team I see what I think is five archetypes: 1. Prototyper: comes up with brand new ideas; churns out many ideas, most of which don't ship 2. Builder: quickly turns a prototype/idea into production-grade product/infra 3. Sweeper: cleans up the UI, simplifies the code and system, unships, optimizes performance 4. Grower: takes a product that has been built and iterates on it to improve Product-Market Fit 5. Maintainer: owns a mature system to make it secure, reliable, fast, and efficient as it scales Many people span across 2 roles, and sometimes 3 roles. I also notice that these roles are not really tied to job function -- eg. across Anthropic, some designers match category 1, some 2, some 3; same for engineers, PM, DS. A healthy team needs a mix of these, depending on the product: - A product that is new and pre-PMF needs people that are strong at 1+2+3 - A product that is growing and has found PMF needs 2+3+4 and some 5 - A product that has strong PMF needs 3+4+5 and some 2 Maybe product roles of the future will look more like this, and less like the domain-specific roles of today?
@bcherny
Andrej Karpathy joined Anthropic five weeks ago. Yesterday my friend on his team sent me the Claude.md file he actually uses. It completely changed how I work with Claude. From the very first message, the difference was obvious. With this file, Claude finally stops fighting me and starts working exactly the way I need it to. Bookmark it before it gets taken down. Read it now, then check the article below.
