What are you all doing to test agentic workflows? It's overwhelming because there are many paths an agent could take. I'm thinking maybe a starting point is verifying that it called expected tools and returned an expected format for critical tasks. #ai #agents #artificialintelligence #agentic

I like seeing passkeys showing up in more places because they're much easier to manage than passwords. It inspired me to do a deep dive on how they work. #nextjs #webauthn #passkeys rebeccamdeprey.com/blog/passkey...

The badges at GitHub universe this year are nuts! Color screen, wifi, Bluetooth. Powered by a raspberry pi 2350 / @pimoroni.com I tried my hand at building an app on the way home.

There’s something magical about physics-based animation. When we use springs instead of Bézier curves, we tend to get way smoother motion. Up until recently, we’ve needed to use JS libraries for this, but a modern feature lets us emulate springs in native CSS. ✨ Just published a new post:

You want to ship a Linear-like experience, so you install some CRDT libraries and expect things to Just Work™. @hausdorff.bsky.social of moment.dev digs into why this isn't that simple. www.youtube.com/watch?v=OGJx... Subscribe to get notified when we ship more videos from #CascadiaJS 2025! 📺

Pretty impressed with the Cursor + Playwright MCP. Within a few minutes, it solved some tedious responsive fixed position updates that would have taken me a while. 🤯 #typescript #playwright #ai #mcp #artificialintelligence #frontend github.com/microsoft/pl...

View Transitions are now in all browsers! They also landed in React! developer.chrome.com/blog/view-tr...

My prototype servers always worked fine, but I wasn’t asking the right questions about security. This time I built one I’d actually trust: a secure MCP server in #TypeScript. For anyone else tired of saying “I’ll handle auth later”: rebeccamdeprey.com/blog/secure-... #mcp #mcpserver #ai

`field-sizing: content` will be so helpful in sizing dynamic text areas. I hope we don't have to wait much longer for it to become widely supported. #css developer.mozilla.org/en-US/docs/W...

Disclaimer: the following is Chromium-only and more than cutting edge, but it's kinda wild that we can implement custom functions like "light-dark()" ourselves eventually. Here's @bram.us looking into the future. 👇 www.bram.us/2025/09/30/c...

Found a bug in a JS dependency and can't wait for the owners to fix it? Download the repo and use Cursor or another AI agent to help you generate a patch with pnpm or patch-package. #javascript #ai #cursor #artificialintelligence

Odyc.js is a small JS library that can be used for narrative games. You can build your game entirely in a single file. Perfect for quick dev or learning. I can't wait to test it out. Read on it here: odyc.dev #OdycJS #JavaScript #GameDev #DevTools

Just got my ticket for @vercel.community Ship - claim yours! vercel.com/ship/ticket/...

Found a "Magnitude" on this week, it looks interesting. That is a Playwright where you write a declarative AI prompts in test files instead of selectors and expected states assertions. There are some problems, but that approach could replace manual QA on small projects. #programming #frontend

Trying to get critical feedback on a piece of writing out an LLM? Tell it someone else wrote it www.seangoedecke.com/lying-to-llms/ #llm #ai #artificialintelligence #promptengineering

Anyone else noticed that LLMs really like the word "keen"? #llm #ai #artificialintelligence

I've taken to following Anthropic's proposed definitions, where they distinguish between a workflow and an agent (and recommend starting as simply as possible). www.anthropic.com/engineering/...

I've been thinking a lot recently about the differences between #AI agents and workflows. This Latent Space post does a good deep dive on the topic, www.latent.space/p/agent. A key takeaway for me is that agents determine their own workflows. #artificialintelligence #agentengineering #agents

Can you believe this demo uses NO JavaScript!? I'm trying out 2 new web platform features: 1. popover=hint prevents other popovers from closing when opened (landed in Chrome 133) 2. interesttarget to open the comment details on hover/focus (WIP, origin trial, needs work for touchscreen behavior)

This is really clever and fun! @paulbutler.org found a way to hide text 'in' an emoji by hacking the way unicode works. paulbutler.org/2025/smuggli...

AI model randomly returning partial responses? You might need to increase the max tokens when calling it #ai #artificialintelligence #aiengineering #llm

Do multi-agent systems parallelize the work an #LLM does, or is it more for managing different types of tasks (or both)? Google's new Agent Development Kit looks neat #ai #artificialintelligence #aiengineering

Microsoft just introduced a new external knowledge architecture for LLMs. Beats RAG in performance, less hallucinations. Also apparently the knowledge base can be updated at inference time, which is huge. #AI #artificialintelligence #machineLearning #AIResearch #ML www.microsoft.com/en-us/resear...

Anthropic's "AI microscope" approach to see inside how AI models "think" is fascinating. Are there any UIs that help visualize each step an AI takes as its "thinking" of a response? www.anthropic.com/research/tra... #ai #artificialintelligence #anthropic #llm #largelanguagemodels #aiengineering

Nice to see that Google and OpenAI are onboard with supporting Anthropic's MCP (Model Context Protocol). Early adoption of standards will make it easier to interconnect models with other systems. #ai #artificialintelligence #openai #anthropic #gemini #mcp #modelcontextprotocol

You probably aren't using PropertyKey enough. It represents any valid key in JavaScript: string, number or symbol. And it's globally available in every TS project. #typescript #javascript #buildinpublic

@yubico.com Any plans for a yubikey ring in the future? That form factor seems like it would be nice

I'm finding that Codellama is better than Starcoder for consistently generating React components as output. #react #javascript #ai #programmingwithai #generativeui

@turbo.build Loving turborepo's generator feature so far! It's convenient to have a built-in way for people to spin up new packages with standard defaults.
