OpenCode Plugin Generator

This workflow pack enables OpenCode to generate its own TypeScript plugins. It bundles the SDK documentation, a slash command that triggers the workflow, and a required agent profile.

Installation

Add to your opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["@howaboua/create-opencode-plugin@latest"]
}

OpenCode installs plugin dependencies automatically on next launch.

For local development:

{
  "plugin": ["file:///absolute/path/to/create-opencode-plugin/dist/index.js"]
}

Usage

Use the slash command to generate a new plugin:

/create-plugin "block any bash command that contains 'rm -rf'"

The command triggers the workflow, loading the agent and skill to look up the correct SDK hooks and generate TypeScript code.

Components

• Command (/create-plugin): Triggers the workflow and passes your description to the agent.
• Skill (create-opencode-plugin): Contains the API reference, event types, and TypeScript definitions. This ensures the generated code compiles.
• Agent (Plugin Creator): Required specialized agent profile tuned for plugin development.

Skill Configuration

[!NOTE] The Plugin Creator agent has 1 skill enabled by default: create-opencode-plugin. All other skills are blocked with "*": "deny". This ensures the agent focuses on plugin development without context pollution.

The agent's YAML frontmatter controls skill access:

permission:
  skill:
    create-opencode-plugin: allow
    '*': deny
