OpenCode plugin for Obsidian

Give your notes AI capability by embedding Opencode OpenCode AI assistant directly in Obsidian:

Use cases:

• Summarize and distill long-form content
• Draft, edit, and refine your writing
• Query and explore your knowledge base
• Generate outlines and structured notes

This plugin uses OpenCode's web view that can be embedded directly into Obsidian window. Usually similar plugins would use the ACP protocol, but I want to see how how much is possible without having to implement (and manage) a custom chat UI - I want the full power of OpenCode in my Obsidian.

Note: plugin author is not afiliated with OpenCode or Obsidian - this is a 3rd party software.

Requirements

• Desktop only (uses Node.js child processes)
• OpenCode CLI installed
• Bun installed

Installation

1. Clone to .obsidian/plugins/obsidian-opencode subdirectory under your vault's root
2. Run bun install && bun run build
3. Enable in Obsidian Settings > Community plugins
4. Add AGENTS.md to the workspace root, use it to explain the structure

Usage

• Click the terminal icon in the ribbon, or
• Cmd/Ctrl+Shift+O to toggle the panel
• Server starts automatically when you open the panel

Context injection (experimental)

This plugin can automatically inject context to the running OC instance: list of open notes and currently selected text.

It can be configured form the plugin settings.

Currently, this is work-in-progress feature with some limitations:

• It won't work when creating new session from OC interface.
