opencode-multi-copilot

OpenCode plugin for multi-account GitHub Copilot workflows.

Features

• Store multiple Copilot OAuth accounts in multi-copilot.json
• Switch the global default account (syncs into auth.json)
• Bind a different account per session (parallel multi-account usage)
• Preserve core behavior: session switch does not overwrite global active auth
• Support both GitHub.com and GitHub Enterprise Copilot

Architecture

This plugin extends OpenCode’s auth model with three layers:

1. Multi-account state in ~/.local/share/opencode/multi-copilot.json
2. Global active sync into ~/.local/share/opencode/auth.json
3. Session-level binding via sessionID headers and provider fetch routing

Installation

Local plugin development

OpenCode reads:

• .opencode/plugins/multi-copilot.js
• .opencode/commands/*.md

Build once before first use:

npm install
npm run build

multi-copilot.js loads from dist/src/index.js.

npm package usage

After publishing, install and register the plugin in opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["opencode-multi-copilot"]
}

Login flow

Use the native OpenCode command:

opencode auth login -p github-copilot

The plugin intercepts provider auth and will:

• complete device flow polling
• normalize enterprise domains
• persist/update the account in multi-copilot.json
• set that account as global active
• sync auth.json for immediate provider use

Better account switching UX

Guided picker flow (Quick Pick style fallback)

/copilot-pick

Shows an indexed list and lets you switch by:

• index (1 or #1)
• alias (case-insensitive)
• full account ID

Direct switching

/copilot-switch work
/copilot-switch #2
/copilot-global personal

If /copilot-switch is run without arguments, it now returns guided pick instructions instead of a raw error.

Status and management

• /copilot-accounts
• /copilot-status
• /copilot-unbind
• /copilot-import [alias]
• /copilot-rename <account> <new-alias>
• /copilot-remove <account>
• /copilot-sync

Tool API

The plugin exposes copilot_accounts with actions:

• list
• pick
• status
• switch
• unbind
• remove
• rename
• import-current
• sync

switch.account accepts id, alias, or indexed references (1, #1).
