shellscript-add

Use this skill whenever the user wants to add a new installer script to the shellscript.download project. Trigger when the user says things like "add a script for X", "create a new script to install Y", "write a .sh for Z", "add <tool> to the catalog", or any request to create or write a new public/scripts/*.sh file. Also trigger when the user asks how to contribute a new script or what the pattern for a new script looks like.

Install​

Claude Code: add the catalog once, then install the skill:

/plugin marketplace add byjg/skills
/plugin install shellscript-add@byjg

Or declare it in a project's .claude/settings.json, so Claude Code offers it to everyone who opens the project:

{
  "extraKnownMarketplaces": {
    "byjg": {
      "source": {
        "source": "github",
        "repo": "byjg/skills"
      }
    }
  },
  "enabledPlugins": {
    "shellscript-add@byjg": true
  }
}
