Agentmemory Launcher for OpenCode

OpenCode plugin that auto-starts the agentmemory backend with health-check supervision.

Requirements

• Node.js ≥ 18.0.0
• OpenCode with plugin support
• agentmemory backend (auto-installed via npx @agentmemory/agentmemory if not present)

What It Does

This plugin automatically starts the agentmemory backend (REST API + iii-engine) when OpenCode loads its configuration. It runs once per OpenCode process and health-checks the backend every 60 seconds, restarting it if the process dies.

Installation

From npm (recommended)

Add to your OpenCode config:

// opencode.json
{
  "plugin": ["opencode-agentmemory-launcher@latest"]
}

OpenCode will automatically install the package at startup. See the OpenCode Plugins documentation for more details.

From local file

Place the plugin file in .opencode/plugins/:

.opencode/plugins/
└── agentmemory-launcher.ts

Files in this directory are automatically loaded at startup.

Manual Installation (from GitHub Releases)

1. Download agentmemory-launcher.ts from the latest GitHub Release
2. Place it in .opencode/plugins/:

.opencode/plugins/
└── agentmemory-launcher.ts

OpenCode loads .ts files from .opencode/plugins/ automatically at startup.

Usage

This launcher starts the agentmemory backend. To use agentmemory with OpenCode, also install the agentmemory plugin and refer to the OpenCode agentmemory plugin usage guide for setup instructions, available tools, and configuration options.

How It Works

1. On first config load: The plugin starts a health-check interval (60s)
2. Health check: Pings GET /agentmemory/livez on the backend (public, no auth)
3. Auto-restart: If the health check fails, spawns npx @agentmemory/agentmemory in a detached process
4. Debug mode: Set OPENCODE_AGENTMEMORY_DEBUG=1 for verbose logging

Environment Variables

Variable	Default	Description
AGENTMEMORY_URL	http://localhost:3111	Backend API URL
OPENCODE_AGENTMEMORY_DEBUG	unset	Set to 1 for debug logging

API

The plugin exports a single object conforming to the @opencode-ai/plugin interface:

import type { Plugin } from "@opencode-ai/plugin";

export const AgentmemoryLauncherPlugin: Plugin;

This plugin implements the config lifecycle hook, which is called each time OpenCode loads its configuration.
