skills

skills for coding agents. every skill lives under skills/ as a plain SKILL.md, so any agent that speaks the skill format can use this repo. claude code and codex each get a native plugin on top of that.

install

any agent

npx -y skills add hubermjonathan/skills

this is the main path. it copies the skills into whichever agent you point it at and works for agents with no plugin system of their own.

claude code

as a marketplace, which picks up every skill in the repo and keeps them updated together:

claude plugin marketplace add hubermjonathan/skills
claude plugin install skills@hubermjonathan

or from inside a session:

/plugin marketplace add hubermjonathan/skills

to declare it in ~/.claude/settings.json instead, user scope, since project and local scope cannot vouch for a marketplace:

{
  "extraKnownMarketplaces": {
    "hubermjonathan": {
      "source": { "source": "github", "repo": "hubermjonathan/skills" }
    }
  },
  "enabledPlugins": { "skills@hubermjonathan": true }
}

codex

codex plugin marketplace add hubermjonathan/skills
codex plugin install skills

the repo carries a portable plugin.json and a codex marketplace manifest at .agents/plugins/marketplace.json. each skill also ships an agents/openai.yaml so it gets a proper display name in codex.
