Show HN: Skillstore – Expert skills your coding agent fetches as it works
skillstore-jk.fly.dev
Hey HN I was originally a bit frustrated with having to scour github repos for the right skill while I tried to improve an iOS app's Swift animation.
Then I got frustrated with having to force the agent to use the right skill for the right task.
So I built Skillstore: a library of engineering skills behind an MCP server. Claude Code and Codex can search it, load relevant instructions, and apply them to your task. You don’t need to know the skill’s name beforehand.
Skills are loaded on demand, so you don’t have to keep the whole library in your prompt. (ideally with help you also save tokens and preserve the context window)
ex: In our running app, a review using Paul Hudson’s SwiftUI skill caught undersized touch targets and controls that VoiceOver couldn’t meaningfully identify. We fixed those before the release. In our gym app, a Skillstore-guided review caught an onboarding layout overflowing on small iPhones at large text sizes.
You describe the work → your agent finds relevant expertise → your agent uses it.
You dont have to browse github repos and filter by stars anymore. And you dont have to invoke skills by name You can also give your team a shared library of private skills
Been using it inhouse and with friends for the past 2 months.
Favorite feature so far: Turning a tutorial into a private skill, so the agent can use that knowledge on future tasks when the time is right
You can try the public library without an account https://skillstore-jk.fly.dev/developers#try
