Use when developing plugins, tools, and extensions for OpenCode v1 - plugin contract, crash-prevention rules, ctx/event APIs, subagent lifecycle (abort races, compaction, orphan detection), MCP integration, testing patterns, or publishing to npm.
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.

# OpenCode Plugin Development Complete, field-tested guide for developing plugins for OpenCode (v1.18+) AI coding agent. > **Every rule, signature, and pattern below was verified against a production > plugin that went through 5 versions and 3 distinct crash classes.** The "Hard-won > rules" sections are non-negotiable — > violating them silently breaks the host. --- ## Extension Types — When to Use What | Extension Type | Best For | Example | |----------------|----------|---------| | **Plugin (Hooks)** | Event-driven automation, custom tools, recovery logic | Auto-resume stalled sessions, enforce agent selection | | **Tools** | AI-triggered actions inside a plugin | `task_complete`, `commit`, custom search | | **MCP Servers** | External service integrations | Databases, GitHub, filesystem, remote APIs | | **Skills** | Knowledge/prompt templates (this file is one) | Framework patterns, project conventions | | **Commands** | Interactive slash shortcuts | `/hello`, `/deploy` | | **Providers** | Custom LLM backends | Alternative API gateways, self-hosted models | --- ## The Plugin Contract (v1.18+) — Read This First …

How to install
mdr add codeatcode/oss-ai-skills/opencode@sha256:ff04cec2e01e38e6The line at the top of this page pins the label v3.2.0, 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.
