Absolutely agree. A lot of LLM-driven work is just inflated busywork with little real output. High token usage doesn’t equal genuine productivity, just unnecessary repetitive verification and paperwork.

This seems quite interesting... I'll give it a try

  I've always found it a bit overkill to open heavy software just to generate a quick normal map. Most online tools either have clunky UIs or upload your files to their backend.
I built this using Three.js and client-side canvas processing (Sobel/Scharr filters). Everything happens locally on your machine, so it's fast and private. Features: - Generate Normal, Displacement, AO, and Specular maps. - Real-time 3D PBR preview with shape selection (Plane, Cube, Sphere). - Fine-grained control over strength, blur, and axis inversion. Would love to get some technical feedback on the processing performance!

Hi HN,

I'm the maker of MCPxel (https://mcpxel.com).

The Problem: As an active user of Claude/MCP, I found the ecosystem fragmented. Searching GitHub for "agent skills" returns thousands of results, but many are broken, outdated, or just simple wrappers. Stars often don't correlate with reliability.

The Solution: I built MCPxel to curate and rate these skills.

How it works:

LLM-as-a-Judge: We use an automated pipeline to evaluate skills on 5 dimensions (Clarity, Utility, Quality, Maintainability, Novelty). S-Tier Filtering: We assign grades (S/A/B/C). S-Tier skills are verified to work out of the box. Role-Based Search: Instead of keyword guessing, you can find tools tailored for specific workflows (e.g., "frontend dev"). Tech Stack: Built with Next.js. We used TRAE (AI IDE) and DeepSeek-V3 heavily during development to accelerate the process.

Try it out: Check out the LLM-judged ratings (S/A/B/C). I'd love to know if the scores match your experience with these tools!

Hey everyone,

I remember struggling with Calculus back in the day, specifically with knowing which rule to apply and when.

I decided to build a tool to help with that. It's a Derivative Calculator that focuses on explaining the solution, not just giving the result.

Why I made it: Most calculators are either paid or just dump the final LaTeX string. I wanted something that visualizes the graph and walks you through the Chain Rule, Product Rule, etc., just like a tutor would.

How we built it We built this project using a modern, performance-focused stack: - Framework: Next.js 15 (App Router) for a blazing-fast, server-rendered experience. - Math Engine: We integrated nerdamer for symbolic computation to handle the heavy lifting of differentiation logic. - Visualization: We used function-plot to build a custom interactive graphing engine that renders functions and their derivatives in real-time. - UI/UX: TailwindCSS and Shadcn/UI ensured the interface remained clean, accessible, and distraction-free.

It's completely free and doesn't require any login.

I'm looking for feedback on the "Steps" generation—does the logic follow how you'd solve it manually?

Thanks for checking it out!
