I had a bunch of Skills sitting in a folder. None of them were callable as APIs

So I built a runtime to fix that. The problem If you use Claude Code, Copilot, or Codex, you've probably created Agent Skills, those SKILL.md files that tell the AI what to do. I had a bunch of them. But they were stuck. I couldn't plug them into a product, trigger them from a webhook, or let any service call them with a POST request. Each skill was trapped inside the tool that created it. What I wanted take a SKILL.md → get a POST /run endpoint No new framework to learn. No infrastructure to set up. Just point at a skill, configure the model, and deploy. What I built Skrun, an open-source runtime that takes Agent Skills and turns them into callable APIs. skrun init --from-skill ./my-existing-skill # reads SKILL.md, generates agent.yaml skrun deploy # validates, builds, pushes # → POST http://localhost:4000/api/agents/dev/my-skill/run Then you call it: curl -X POST http://localhost:4000/api/agents/dev/code-review/run \ -H "Authorization: Bearer dev-token" \ -H "Content-Type: applicatio
