 ### Breaking Changes
 
+ - [[#9045]](https://github.com/Azure/azure-dev/pull/9045) The `--host` skill flag on `azd tool install`, `azd tool upgrade`, and `azd tool uninstall` has been renamed to `--agent`. Installed skills in `azd tool list --output json` and `azd tool check --output json` now expand into one row per agent and include the `agent` field. Update scripts and JSON consumers accordingly.
