Skillly
Your AI agents' skills, kept up to date. Every Day.
Skillly finds the skills installed on your Mac, checks once a day which ones have a newer version, and updates them only after you confirm, with a backup and one-click Undo.
Hey Product Hunt 👋
I’m Elias, and I build web and mobile apps with Claude Code, Codex and Cursor every day.
Over the last months my skills folders kept growing. I’d add skills from marketplaces, plugins and copy-paste, and then forget about them. When an author shipped a better version, nothing told me. When I did update by hand, I was overwriting folders my agents depend on, with no backup and no way back.
So I built Skillly, a small Mac app that:
🔍 finds the skills Claude Code, Codex and Cursor use on your Mac
🕐 checks once a day which ones have a newer version (it only contacts github.com)
✅ shows you exactly which folders will change, from which version to which, before touching anything
↩️ backs everything up first, verifies each update, and gives you one-click Undo
Under the hood it runs on a Rust engine I’ve been working on for a while. If Skillly can’t prove which version a skill came from, it won’t update it. I’d rather skip a skill than silently overwrite someone’s local changes.
It’s $5, lifetime, per Mac. No subscription.
You can try the real app right on the homepage: skillly.app (the demo runs on fake data).
I’d love your feedback, especially:
which other agents or skill sources I should support next
what would make you trust a tool that writes to your agents’ folders
Thanks for checking it out 🙏
