Show HN: 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 Code’s `/plugin marketplace add <repo>`.

Curious whether any of this resonates. Also excited to hear any interesting System Skill ideas worth exploring!
