Show HN: Sk` – manage AI agent skills across Claude, codex, opencode, et all

I love skills, I have a whole collection of skills I've built myself for problems I experience while using AI agents. but the current method of managing skills in codex/opencode is pretty garbage (copy skills into the correct folder). so i built `sk` One manifest, multiple agents — Define skills once in agents.toml, sync to all your AI coding tools Cross-agent compatibility — Use Claude Code plugins with Codex and OpenCode; sk extracts skills from .claude-plugin packages and syncs them everywhere Team-shareable — Commit agents.toml to version control; teammates run sk sync Live development — Local packages use symlinks; edit skills and changes appear instantly Smart reconciliation — Only updates what changed; safely removes stale skills without touching manually-added ones Flexible sourcing — Pull from GitHub, any git remote, local paths, or existing Claude Code plugins check it out!
