Create OpenCode plugins using the opencode-ai/plugin SDK. Use when user wants to build a plugin, extend OpenCode, intercept tool execution, add custom tools, react to events, create a hook, block commands, add custom auth, or add automation to OpenCode. Also use for 'opencode plugin', 'custom tool', 'tool hook', 'plugin hook', 'logging for all tool calls', 'restrict what commands the AI can run', 'lifecycle hooks', 'middleware', 'tool.execute.before', 'tool.execute.after', 'auth hook'…
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
# Creating OpenCode Plugins
## Quick Start
Plugins live in `.opencode/plugins/<name>/index.ts` (project) or `~/.config/opencode/plugins/<name>/index.ts` (global).
```typescript
import type { Plugin } from "@opencode-ai/plugin"
export const MyPlugin: Plugin = async ({ project, client, $, directory, worktree }) => {
return {
// Add hooks here — see references/hooks.md for available hooks
}
}
```
Register in `opencode.json`:
```jsonc
{ "plugin": ["file:///.opencode/plugins/my-plugin/index.ts"] }
```
Optional — document plugin purpose in a companion agent file:
```markdown
---
description: Plugin guard — intercepts tool calls, validates bash commands, blocks dangerous deletions, logs audit trail, hooks session events
---
```
Then test: `opencode run hi`
## Mindset
Plugins are **async factory functions** returning hook implementations. They run once on load. Hooks fire at lifecycle points (tool execution, events, config load). Think of them as middleware layers.

How to install
mdr add pantheon-org/tekhne/opencode-build-plugins@sha256:5ad5fa9b46a670faThe line at the top of this page pins the label git:20260314.95ea1b2, 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.
