Skrun

Deploy any agent skill as a production REST API in one command

Skrun is an open-source tool that wraps agentic skills — the discrete, reusable capabilities you build for AI agents (web search, data extraction, file transformation, API calls) — into deployable REST APIs with a single command. The idea is that skills you build for one agent context shouldn't be locked to that agent's runtime. With Skrun, you define a skill once with a standard function signature, and get a hosted endpoint with automatic request validation, retry logic, rate limiting, and an OpenAPI spec generated automatically. The project addresses a real architectural tension in the current AI tools ecosystem: agent skills are written in a dozen different formats (LangChain tools, MCP tools, function call JSON, OpenAI tool specs) and are essentially stranded assets — they only work within their specific orchestration framework. Skrun normalizes this by wrapping any skill definition format and exposing it as a framework-agnostic HTTP endpoint that any agent or pipeline can call. This appeared on Hacker News with a small but thoughtful discussion focused on the "skills as microservices" architectural pattern. Critics noted that adding HTTP round-trips to every tool call introduces latency; proponents argued that the composability and reusability benefits outweigh the cost. The early version focuses on stateless skills; stateful/conversational skill deployment is on the roadmap.

Panel Reviews

The Builder

Developer Perspective

“The framework portability angle is the real value prop — I have dozens of custom tools built for Claude that I can't reuse in other contexts without rebuilding them. If Skrun actually normalizes this cleanly across tool formats, that's a genuine pain solver.”

The Skeptic

Reality Check

“Wrapping every agent skill in an HTTP call is a latency antipattern — a skill that takes 50ms locally becomes 120ms+ through a hosted endpoint with cold starts. For skills called hundreds of times per agent run, this adds up fast. I'd want colocation support before using this in production.”

The Futurist

Big Picture

Ship

“Skills-as-services is the right architectural direction as agent ecosystems mature. The future is marketplaces of composable agent capabilities that any orchestrator can call — Skrun is early infrastructure for that world.”

“Too deep in infrastructure for my workflow, but the auto-generated OpenAPI spec is a nice touch for anyone who needs to share custom skills with a team without writing documentation manually.”
