OpenCode

OpenCode is an open source AI coding agent.

Configuration

Copy the config examples from ./config into ~/.config/opencode/.

• Copy config/opencode.json to ~/.config/opencode/opencode.json
• Copy config/tui.json to ~/.config/opencode/tui.json

opencode.json contains runtime, provider, and MCP settings.

tui.json contains TUI-only settings like theme and keybinds.

The runtime config example includes:

• Settings for using local models through llama.cpp and LM Studio
• Playwright MCP configuration for local server using @playwright/mcp@latest

Relevant documentation:

• llama.cpp provider docs
• LM Studio provider docs

Local llama.cpp Note

If you want to use OpenCode with local models, start with the guide in ../llama-cpp.

For coding-agent use, OpenCode should connect to a running llama-server instance.

Coding tools usually need more prompt space than normal chat, so context size can matter more here than it does for casual terminal use.

Commands

Copy the commands folder to /Users/[your-username]/.config/opencode/commands/

Available commands:

Command	Path	Description
/git-commit	commands/git-commit.md	Stage and commit changes with safety checks and a generated message.
/git-push	commands/git-push.md	Push the current branch with safety checks and optionally create a PR.

Custom agents/modes

You can define project-specific custom agents by adding an .opencode/agent/ folder inside your project.

This makes the custom mode available only for that project.

Copy the .opencode folder into your project to try it.

Name	Scope	Path	Description
FunMode	Project-specific	.opencode/agent/funmode.md	Example custom mode with a playful, high-personality response style.

Once copied, init OpenCode and press Tab to switch modes, you should see a new FunMode available.
