Windows Setup for Agent Mode

Use this guide to connect OpenCode, Claude Code, or Codex to Copilot Agent Mode on Windows.

OpenCode (Recommended)

Open Agent Mode from the left ribbon or run Open Copilot Agent Chat Window. Choose OpenCode, then select Download OpenCode to let Copilot install and manage it for you.

If you already installed OpenCode, choose I already have it and let Copilot find the binary or enter its path. You can change the source later under Settings → Copilot → Basic → Agents → OpenCode → Configure.

Claude Code

Run this in PowerShell:

irm https://gist.githubusercontent.com/logancyang/7a87eb38d91015eac567521f8cc9c729/raw/install-claude-agent-mode-windows.ps1 | iex

When Claude asks you to sign in, finish the browser login. The installer copies the claude.exe path to your clipboard.

In Obsidian: Settings -> Copilot -> Basic -> Agents -> Claude -> Configure -> Auto-detect. If it doesn't find Claude, paste the copied path into the binary path field, then save.

Run Open Copilot Agent Chat Window, pick Claude, and send a message.

A "not in your PATH" warning is normal and does not matter: Copilot finds Claude by file path, not PATH.

Codex

Run this in PowerShell:

irm https://gist.githubusercontent.com/logancyang/380ef4dbf9f98900771da76eca3d21e6/raw/install-codex-agent-mode-windows.ps1 | iex

When Codex asks you to sign in, finish the login. The installer copies the codex-acp.exe path to your clipboard.

In Obsidian: Settings -> Copilot -> Basic -> Agents -> Codex -> Configure. Paste the copied path into the binary path field, leave Environment variables empty, then save.

Run Open Copilot Agent Chat Window, pick Codex, and send a message.

Use the copied codex-acp.exe path only. Do not use codex.exe, codex.cmd, or codex-acp.cmd.
