Reusable Agent Skills Need Pre-Call Runtime Checks

OpenAI’s recent Codex research includes one detail that matters for developers building agents:26.6% of users use skills to share instructions for complex workflows, and more than 10% manage three or more concurrent Codex agents at some point each week.That means agent usage is moving from one-off prompts toward reusable workflows.That is good.It also means failures can become reusable.The problemA bad prompt can waste one model call.A bad agent skill can waste many runs.A skill might encode:how

ConnectNow: A Full-Stack Social Media App from Scratch

A journey from React basics to production deployment — lessons learned building a real-world social networking platform The ProblemI wanted to learn full-stack development, but most tutorials felt disconnected from reality. Todo apps and weather widgets don't teach you about real-world challenges like:Managing complex database relationships (users, posts, comments, messages)Handling authentication securely at scaleDealing with Render's ephemeral filesystem destroying uploadsBuilding respons

useOptimistic + useActionState: React 19 Killed 50 Lines of My Boilerplate

Every form submission in React used to look like this:const [data, setData] = useState(null)const [loading, setLoading] = useState(false)const [error, setError] = useState(null)async function handleSubmit(e) { e.preventDefault() setLoading(true) try { const result = await submitToServer(formData) setData(result) } catch (err) { setError(err.message) } finally { setLoading(false) }}Three useState calls. A try/catch/finally. Manual loading and error flags. And that's without opti

How I Built GitPulse: A Cinematic Developer Storyteller (and why standard GitHub profiles are boring)

Let's be honest — standard GitHub profiles are a bit... static.As a Full Stack Developer & AI/ML Specialist, I wanted a way to showcase my contributions that actually felt alive.

I built a free UAE calculator platform that runs on live government data

Living in the UAE means constantly Googling numbers: what is the visa fee now, how much zakat do I owe, what is today's fuel price, how is my gratuity calculated. The answers online are usually outdated.So I built Adad, a free set of 15 calculators that pull from official UAE government sources and refresh every 24 hours. No sign-up, works in 8 languages.A few that people use most:Visa fees: real GDRFA and ICA ratesZakat: gold, silver, savingsDEWA bills: estimate before the bill landsGratuity: U

How I Built a Free Twitch Emote Resizer Tool

How I Built a Free Twitch Emote Resizer ToolAs a Twitch streamer, I always struggled with getting my emotes sized correctly for upload. Twitch requires specific pixel dimensions: 28×28, 56×56, and 112×112 pixels. Even being one pixel off causes the upload to fail.I decided to build a free tool to solve this problem once and for all. The ProblemEvery time I created a new emote, I had to:Open an image editorResize to three different dimensionsExport each version separatelyHope I got the

The Zod trap: Why your AI agent is breaking MCPFusion architecture

I was reviewing an agent's recent output for a new MCP server implementation, and at first glance, it looked perfect. The TypeScript was clean, the types were explicit, and the logic followed the requirement to list users from a database.Then I actually looked at how it defined the schema. It used z.object().If you're using MCPFusion, that's an immediate failure. It doesn't matter if the code 'works' in a vacuum; it violates the entire architectural contract we built to make these agents product

Building a Type-Safe API Layer in Next.js App Router With Zod and Server Actions

Server Actions in Next.js App Router look deceptively simple — write an async function, mark it with 'use server', call it from a Client Component. The surface area is small.The problems surface when you start thinking about validation, error handling, and type safety across the client-server boundary. Without a deliberate approach, you end up with untyped form data on the server, error handling that varies across actions, and client code that can't trust the shape of what comes back.Here's the

I Built a Browser-Only JSON Schema Validator — Draft-07, $ref, allOf/anyOf/oneOf, if/then/else, 173 Tests

I Built a Browser-Only JSON Schema Validator — Draft-07, $ref, allOf/anyOf/oneOf, if/then/else, 173 TestsJSON Schema validation usually means pulling in ajv or a similar library. That's entirely reasonable for production code — but for quick schema checking, debugging, or learning how Draft-07 keywords work, you don't want to spin up a Node project just to paste in some JSON.So I built a zero-dependency browser tool that implements the Draft-07 spec from scratch.Live tool → json-schema-val

Custom e-commerce on Firebase: catalog, atomic orders and admin panel

I Built a Visual SVG Wave Generator in Pure Vanilla JS — 5 Wave Types, Download SVG/PNG, 162 TestsWave dividers are one of those design details that look effortless in a finished layout but are surprisingly fiddly to produce by hand. Getting the Bézier control points right for a smooth sine wave, stacking multiple layers with the right opacity offsets, tuning amplitude and period until it "feels" right — it's the kind of thing you want a tool for.So I built one.

Signed token between two PWAs: HMAC-SHA256 with no backend

The problem: two Firebase projects, no shared statePanelControl is an internal PWA that manages operators, calendar and chat for a commercial team. From the panel, team members need to open a separate site — let’s call it Orders — running on a completely different Fireba

How I Rotate PDFs in the Browser with Vue 3 and pdf-lib

Rotating a PDF sounds like the simplest operation imaginable. Yet building it client-side has a few nuances worth documenting. Users expect to upload a file, pick an angle, and get a fixed PDF back — all without uploading their document to a server.I built en.sotool.top/rotate/ to do exactly that. Here's how it works with Vue 3 and pdf-lib. Why Client-Side Rotation?PDFs often contain sensitive information. Scanned contracts, handwritten notes, receipts. Rotating a file on a server means tru
