Agent plugins

Installation

Plugins are compatible with both GitHub Copilot CLI and Claude Code. Within the coding assistants, you can run the same commands with /plugin instead of the plugin CLI command e.g.,

/plugin marketplace add heaths/plugins

GitHub Copilot CLI

To install this marketplace into GitHub Copilot CLI run:

copilot plugin marketplace add heaths/plugins

Claude Code

To install this marketplace into Claude Code run:

claude plugin marketplace add heaths/plugins

Sharing with contributors

You can recommend this marketplace and its plugins to everyone who works in a repository by committing a .claude/settings.json file to that repository. When contributors trust the project folder in Claude Code, they are prompted to install the marketplace and any enabled plugins.

Example .claude/settings.json:

{
  "extraKnownMarketplaces": {
    "heaths-plugins": {
      "source": {
        "source": "github",
        "repo": "heaths/plugins"
      }
    }
  },
  "enabledPlugins": {
    "linting@heaths-plugins": true
  }
}

Note: GitHub Copilot CLI does not currently support project-level plugin recommendations. Contributors using Copilot CLI should run the marketplace and plugin install commands above individually.
