+# Milestone 2 Sub-plan: Basic CLI Management
+
+## 1. Objective
+
+Enable developers to manage their remote workspaces directly from the local
+`gemini-cli`.
+
+## 2. Tasks
+
+### Task 2.1: CLI Command Infrastructure
+
+Add the base `workspace` command and its sub-commands to the CLI.
+
+- [x] Save post-mortem of "Command Registration & UI Bypass" failure to global
+      memory.
+- [x] Investigate why `workspace` command is shadowed by positional `query..` in
+      `yargs`.
+- [x] Ensure `workspace` commands correctly bypass the interactive UI.
+- [x] Define the `workspace` command group logic in
+      `packages/core/src/commands/`.
+- [x] Implement `wsr list`: Fetch and display workspaces from the Hub.
+- [x] Implement `wsr create <name>`: Call the Hub API to provision a new
+      workspace.
+- [x] Implement `wsr delete <id>`: Call the Hub API to terminate a workspace.
+
+### Task 2.2: Hub Configuration & Discovery
+
+Allow the CLI to know where the Workspace Hub is located.
+
+- [ ] Add `workspaces` configuration section to `packages/core/src/config/`.
+- [ ] Support multiple Hub profiles in `settings.json`.
+
+### Task 2.3: Basic Hub Client & Auth
+
+Implement the communication layer between the CLI and the Hub.
+
+- [ ] Create `packages/core/src/services/workspaceHubClient.ts`.
+- [ ] Implement Google OAuth/IAP token injection for API requests.
+- [ ] Handle API errors and provide user-friendly feedback in the CLI.
+
+## 3. Verification & Success Criteria
+
+- **List:** `gemini workspace list` shows workspaces currently tracked in
+  Firestore.
+- **Create:** `gemini workspace create my-task` returns a success message and
+  the new workspace ID.
+- **Delete:** `gemini workspace delete [ID]` removes the entry from the list.
+- **Auth:** Commands fail with a clear message if the user is not authenticated
+  or the Hub is unreachable.
+
+## 4. Next Steps
+
+- Implement Task 2.1: Add the `workspace` command group to the CLI.

 ### Milestone 2: Basic CLI Management (Phase 2)
 
-Enable developers to manage their remote fleet from the local CLI.
+Enable developers to manage their remote fleet from the local CLI. See
+[Milestone 2 Sub-plan](./milestone-2-cli-management.md) for details.
 
 - [ ] Add `gemini workspace create/list/delete` commands.

 - [ ] Implement Hub authentication (Google OAuth/IAP).
 - [ ] Add local configuration for Hub discovery (`settings.json`).
