Install [Git for Windows] (https://git-scm.com/download/win)
then open PowerShell as admin:
install NodeJS:
winget install OpenJS.NodeJS.LTS
update your system's execution policy to allow locally written scripts to run:
Set-ExecutionPolicy RemoteSigned -Scope LocalMachine
then install codex:
npm install -g @openai/codex
and the codex acp:
npm install -g @agentclientprotocol/codex-acp
then install Claude:
npm install -g @anthropic-ai/claude-code
then the claude acp:
npm install -g @agentclientprotocol/claude-agent-acp
re open the Buzz app and it should now find it

WORKAROUND: Manually install
npm install -g @agentclientprotocol/claude-agent-acp --verboseNOTE: This took 45 minutes to complete. I'm wondering if Buzz was simply timing out when it tries to install the Claude Code ACP itself. ...just an idea?

Possibly, maybe a path isolation issue within the setup environment?

+1
Installation failed for both codex and claude.
I really hope we can see hermes agent in future too
