Show HN: KatmerCode – Claude Code in Obsidian with academic research skills
I built an Obsidian plugin for my wife (academic researcher). It embeds Claude Code as a sidebar chat using the Agent SDK, and ships with 7 slash-command skills: - /peer-review — 8-criteria manuscript evaluation with radar chart
- /cite-verify — checks references against CrossRef, Semantic Scholar, OpenAlex
Show HN: Neurotrace – The extension I built but never used
I’ve been working in ML software for 4 years, and I quickly ran into a recurring problem: I kept asking myself, "Why did I write this function this way?" or "Why is this block here?"I tried to organize my thoughts with Obsidian and other note-taking apps, but let’s be honest, documenting for yourself feels like a chore. Documentation always feels like it's meant for "someone else."So, I decided to build a VS Code extension to save my reasoning and contextual me
Skills are quietly becoming the unit of agent knowledge
In the last few months agent skills went from a niche Claude Code feature to something every major runtime supports. Anthropic has an official skills repo. OpenAI shipped skills in Codex with a built-in skill-creator. Karpathy talks about "everything is skill issue" and describes writing skills as curricula for agents [1]. The format is converging: a folder with a SKILL.md, optional scripts, optional reference files.What changed is that the models got good enough to follow written inst

We launched a lead magnet and got 300 people interested in 24 hours
We launched a simple lead magnet a couple days ago for Leadpoet.Honestly thought we’d get maybe 50–100 people.We ended up getting 300+ comments in the first 24 hours, and around 150 people booked calls, which we definitely didn’t expect.We didn’t do anything fancy. Just tried to make something actually useful.Shared it on X and that was basically it.What stood out most was how quickly people went from seeing it -> booking a call.Still early so not sure if this is repeatable or just timing, bu
Show HN: Lukan – An open-source agentic workstation in a single Rust binary
Hi HN,
I've been building Lukan, an open-source (MIT) agentic workstation that runs entirely as a single Rust binary with zero runtime dependencies.
I started this because I wanted a unified workstation optimized for my own productivity. My goal was to build an environment where I could securely remote into my machine from anywhere, seamlessly view and modify local files, and run AI agents or drop into a terminal side-by-side, all integrated with a rich set of built-in tools.
Here is what m
