The System Skill Pattern
Hello HN! I’ve been playing with Claude Skills and stumbled on a simple pattern for tiny, durable personal data systems: * CLI: a small, self-contained executable * SKILL.md: the operator guide (what to run, how to parse output, how to think about the system) * SQLite: a local DB for persistent state It’s nothing mind-blowing, but the ergonomics of this combo feel great. If you define a process/flow, Claude can "turn the crank" by running the CLI, accumulating context, and animating the system to life over time. They’re also easy to share: you can distribute System Skills via Claude…
In plain words
The System Skill Pattern is a framework for building personal data systems that combine a command-line tool, a markdown guide, and a SQLite database. Designed for developers and individuals wanting to automate workflows, it works with Claude Skills to execute processes over time while maintaining local state. The pattern emphasizes simplicity and shareability, allowing users to distribute their systems through Claude's plugin marketplace. A reference Pomodoro implementation demonstrates the approach.

Hello HN! I’ve been playing with Claude Skills and stumbled on a simple pattern for tiny, durable personal data systems: * CLI: a small, self-contained executable * SKILL.md: the operator guide (what to run, how to parse output, how to think about the system) * SQLite: a local DB for persistent state It’s nothing mind-blowing, but the ergonomics of this combo feel great. If you define a process/flow, Claude can "turn the crank" by running the CLI, accumulating context, and animating the system to life over time. They’re also easy to share: you can distribute System Skills via Claude Code’s `/plugin marketplace add <repo>`. More details in the blog post and the toy Pomodoro System Skill reference implementation here: Blog: https://www.shruggingface.com/blog/the-system-skill-pattern Repo: https://github.com/jakedahn/pomodoro -- Curious whether any of this resonates. Also excited to hear any interesting System Skill ideas worth exploring!

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
