OpenCode
OpenCode contacts run the opencode installed on your computer, with the same providers, opencode.json, AGENTS.md, custom commands and MCP servers.
Set it up. Install opencode and sign in to a provider:
npm install -g opencode-ai
opencode auth login
It isn't bundled. The app finds opencode on your PATH; set BUDDYLIST_OPENCODE_CLI to use a different one.
Add a contact. Pick OpenCode as the Service in Add a Contact. Models are named provider/model; opencode models lists yours.
You get the same windows as with Claude:
- streamed replies
- a line for each command, file read, file change, search and tool call
- Accept / Always allow / Decline invitations
- Nudge to stop
- conversations that pick up where they left off
- your opencode commands and skills in Activities
OpenCode's Mode menu has its two built-in agents:
| Mode | What it does |
|---|---|
| Build | works on the project, asking only where your opencode settings say so |
| Plan | looks and suggests, without changing anything |
Out of the box, Build doesn't ask before changing files or running commands. To be asked, add this to opencode.json:
{ "permission": { "edit": "ask", "bash": "ask" } }
Good to know:
- A new mode or model applies from your next message.
- Always allow lasts until you quit the app or start a new chat.
- A message sent while OpenCode is busy waits for its turn.
- Agents you defined yourself aren't in the Mode menu.
/undoand/redodon't work here.- It reports what each reply cost.
In a contact's worktree OpenCode uses your main checkout's opencode.json and .opencode/ folder, not the branch's. A worktree's branch can be someone else's pull request, and OpenCode runs the plugins and MCP servers a folder sets up without asking. It still reads the worktree's AGENTS.md. Relative paths in instructions aren't found there; use AGENTS.md or full paths.
