Develop, install, troubleshoot, and integrate OpenCode plugins for the opencode CLI. Use when: writing new OpenCode plugins, porting Pi SDK extensions to OpenCode, registering custom tools via the plugin API, fixing plugin load failures, resolving module dependency issues in plugins, installing plugins globally or per-project, understanding the plugin hook system, or any task involving @opencode-ai/plugin, opencode plugin command, or opencode.json plugin config. Covers: plugin format, Hooks…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OpenCode Plugin Development Guide
Complete guide for developing, installing, and troubleshooting plugins for the OpenCode CLI (`opencode`). Validated against OpenCode v1.14.20 and `@opencode-ai/plugin` v1.14.19.
## Plugin Architecture
OpenCode plugins are **ESM JavaScript modules** that export an async function. The function receives a `PluginInput` and returns `Promise<Hooks>`. Plugins register custom tools, hook into the agent lifecycle, and modify behavior at runtime.
```
Plugin function called once at load time
-> returns Hooks object
-> hooks are called per-event during the session
```
### Plugin File Structure
```
my-plugin/
├── package.json # Must have "type": "module", "main": "index.js"
└── index.js # The plugin code (ESM)
```
Minimal `package.json`:
```json
{
"name": "my-opencode-plugin",
"version": "1.0.0",
"type": "module",
"main": "index.js",
"peerDependencies": {
"@opencode-ai/plugin": ">=1.14.0"
}
}
```
### Minimal Plugin
```javascript
export default async function MyPlugin(input) {
return {
// hooks go here
};
}
```
This is a valid plugin that does nothing. Every hook is optional.
## The Plugin Function

How to install
mdr add valtterimelkko/agent-workflow-skills/opencode-plugin@sha256:1e891f8ba1429d9fThe line at the top of this page pins the label git:20260611.b2584e4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
