Awesome! My experience is that for opinionated rules, its still better to mostly include the rules and fine tune them for better results. Might be short, models understand.
Here is my own take on evals (focusing on opinionated Vue rules and Claude Code).
vue-nuxt-rules.lttr.cz/rule-evals
The AI-assisted dev terminology is finally settling:
→ Vibe coding = prompt, accept, ship, pray
→ Agentic engineering = AI agents implement, you own architecture + quality

Test your knowledge based on how much you laugh while watching this:

And how confident are you that your coding agent knows all of this?
Luca: "Vim, Ryan, are you kidding me? Vim inside of VS Code?"
Ryan: "As God intended."

Great show.
Create a custom command or skill that tells you what you were working on, the relevant state, and how you'd likely want to continue. What matters is getting back into unfinished work quickly and without friction.
We assemble context for AI, but our brain needs onboarding too. The reverse context management move: instead of preparing context for the AI, have the AI prepare context for you.
Claude Code is just an automated copy paste machine. But considering it can copy from almost anything and paste almost anywhere - its quite good 😀
Tell more pls. Do you have your setup online? I am currently using a custom skill, and some commands, but still not satisfied with the workflow which would steer Claude for doing Nuxt and Vue just right.
Evan You just casually announced that @vite.dev implemented the best ideas from Biome, Turborepo and Deno tooling www.youtube.com/watch?v=x7Js...
What a great future for JavaScript!
Today I learned: AX stands for Agent eXperience. Well it actually make some sense. As a developer I want my AI agent to have great experience using my tools on my behalf...
I'll be talking about Tailwind vs. CSS at the FrontKon conference in a couple of weeks. Controversy or harmony? 👀

Counting rows on an unusual chessboard seems simple since you sense there's a trick. But I couldn't get any major LLM to answer correctly without big hints. Do you have similar examples?
Custom CSS framework, but basically plain CSS.
One of the reasons I like using Gemini 2.5 Pro for tech specs is that it can defend its decisions. If I ask, "why didn't you X?" it will give me the rationale and let me debate back and forth. Compare that to Claude: "You're absolutely right! I should have done X." Much less helpful.
Have you tried the Playwright MCP from MS? I have tried that but it has a little bit too many tools maybe and while it works it feels more manual then it needs to be. Do you have any setup with Puppeteer?
Great! Is it something on GitHub that we can take inspiration from?
Great!
Because this is on another level. Check the whole thing @voidzero.dev is cooking.
I have totally missed, that Temporal (built in dates and calendars library) is already implemented in first browser - Firefox. This is great! spidermonkey.dev/blog/2025/04...
One focus on one problem at a time and deal with tasks sequentially. When one wants to check the output of an agent and interact with it, parallelism is not helpful. What is helpful is to get the results fast, so you can focus on the next task and not on another coffee break. 2/2
What is all the rage about parallel AI agents? And how is it great to let the agent work for hours?
I get that it solves the current problems, but overall it feels wierd.
Why? Because humans can't really think in parallel. 1/2
I'm using Instapaper, even on Android e-ink tablet to read articles. Works great.
Take on Claude Code
Question: Why did you build a cli tool instead of an IDE?
Boris from Anthropic: There is good change that by the end of the year people aren't using IDEs anymore.

This is incredible Google WTF!
I have dropped a couple of lines about an exceptional opportunity I had recently at a conference in Amsterodam... lukastrumm.com/blog/the-che...
Awesome time, awesome people in Amsterodam #vuejsamsterdam #jsworld
Unbelievable
