+- **Multi-agent workspace disambiguation.** Opening a second workspace at a path
+  that is already registered no longer overwrites the existing entry when a
+  different agent is selected. Crabby generates a unique workspace name from the
+  path and the agent binary (e.g. `payments-opencode`), so `claude` and
+  `opencode` workspaces can coexist at the same directory and are independently
+  listed on the dashboard.
+- **Per-task agent selection.** Pressing **t** to create a new task now includes
+  an agent-selection step in the creation wizard. The chosen agent is persisted
+  in `projects.json` (`agent_command` field) and used every time that task is
+  opened, independently of the workspace's default agent.
