Plugin Creator

Use this skill when a user wants a local Codewhale plugin bundle. Trusted and enabled bundles may add declarative Skills, commands, agents, hooks, and MCP servers (stdio and remote) through the existing engines. LSP, filesystem roots, and lifecycle mutation are inventory-only. Native extensions (host code) are inventory-only unless the user has turned on the experimental [features] extension_host flag.

Workflow

1. Pick a Codewhale-owned location:
   • User bundle: ~/.codewhale/plugins/<plugin-name>/
   • Workspace bundle: <workspace>/.codewhale/plugins/<plugin-name>/
2. Normalize the bundle name to lowercase hyphen-case.
3. Create plugin.json (Agent Plugins v1.0.0; a legacy plugin.toml stays readable, but new bundles use plugin.json):

{
  "$schema": "https://agent-plugins.org/schemas/plugin.json",
  "name": "my-plugin",
  "version": "0.1.0",
  "description": "What this bundle provides"
}
