Ponytail is a plugin that stops coding agents from over-engineering.
I wrote a deep dive on how it works, how to install it in ChatGPT, Codex, and Claude Code, and how I’d use it.

Turn your project’s visual rules into machine-readable format so AI agents ship consistent UIs without endless prompting.
This new registry makes every public DESIGN. md instantly discoverable and reusable across GitHub repos.

Google Stitch introduced a new concept: DESIGN . md
Like README . md but for design systems. A plain markdown file that LLMs read to generate consistent UI.
An awesome collection of DESIGN . md files inspired by developer-focused websites like Stripe, Vercel, Linear, Notion, Figma and more.
Drop one into your project. Your AI coding agent builds the rest.

I'm Boris and I created Claude Code. I wanted to quickly share a few tips for using Claude Code, sourced directly from the Claude Code team. The way the team uses Claude is different than how I use it. Remember: there is no one right way to use Claude Code -- everyones' setup is different. You should experiment to see what works for you!

Quem trampa com tech precisa saber lidar com a própria insuficiência
De tempos em tempos vai se sentir burro
Sempre que surgirem novos desafios, essa sensação pode fazer você achar que é incapaz. O lance é que cada vez que passar por esse processo você se torna um dev melhor
