Claude Desktop Cowork

Cowork installs plugins from a file instead of a marketplace.

Install

Download chiron.plugin from the latest release.
Open it and click Trust. Chiron’s commands and advisors only load once you trust it.
If nothing happens, go to Extensions → Plugins → Upload and pick the same file.

Start a task and type:

/chiron:council relationship "we keep having the same fight about money"

Check the version in the release title. The file is built when a release is cut, so it can be a little behind the main branch. 0.3.0 and later include the ready-made councils.

What’s different in Cowork

Cowork runs in a sandbox that can’t write to your home folder. Chiron works around that by saving everything in the open workspace instead of ~/.chiron/:

What	In Claude Code	In Cowork
Notes from past questions	`~/.chiron/logs/<advisor>/log.md`	`.chiron/logs/<advisor>/log.md` in the workspace
Your saved councils	`~/.chiron/benches.yaml`	`.chiron/benches.yaml` in the workspace
Advisors you build	`~/.chiron/seats/<id>/`	`.chiron/seats/<id>/` in the workspace

So your history and any advisor you build stay with that workspace. They won’t follow you to a different one.

If no workspace is open when you build an advisor, Chiron packages it as a small .plugin file in outputs/ instead. Open that file and click Trust, the same way you installed Chiron, and the advisor is available in every workspace. Downloading the file isn’t enough on its own; it has to be trusted.

If you keep the workspace in git, add .chiron/ to its .gitignore so your notes are never committed. Chiron offers to do this when it first writes there.

Model choice

Cowork uses one model for the whole session. Councils and building a new advisor are the heaviest jobs, so if an answer comes back thin or the advisors blur together, switch to the strongest model Cowork offers and ask again.

Update

Download the new chiron.plugin from the latest release and open it. It replaces the old version.

Remove

Remove Chiron from Extensions → Plugins. Delete the workspace’s .chiron/ folder if you want its notes gone.

Next: your first council.
