+## New Command Checklist for YBM CLI
+
+This document serves as a checklist to guide the process of adding a new command/subcommand to the YBM CLI tool. 
+Follow each step to ensure the command is implemented, tested, and documented consistently with YBM CLI standards.
+
+### 1. Command Implementation
+
+The following for each command should work(of course including the intended functionality):
+- [ ] **Output Format Support**:
+  - [ ] Ensure support for output formats: **table**, **JSON**, and **pretty**. Ideally, this will be taken care automatically when you implement your formatter using `internal/formatter` package.
+    - **Table**: Display data in a structured table format, suitable for terminal viewing. Refer commands like `$ ybm cluster list`. THis is default output format.
+    - **JSON**: Provide output in raw JSON format for easy parsing.
+    - **Pretty JSON**: Format JSON output in a human-readable way, with indentation.
+  - [ ] Test output in each format to verify correct display and structure.
+- [ ] **Async Operation Support**:
+  - [ ] For commands with asynchronous operations (e.g. `cluster pause` or `resume` etc), implement support for the `--wait` flag.
+    - When `--wait` is specified, the command should wait until the operation completes and display the final status. This flag is globally added to all commands, to implement it you need to call [this](https://github.com/yugabyte/ybm-cli/blob/c24aca2700307de5d8f91735e9e75659f1c25847/internal/client/client.go#L1327) i.e. `authApi.WaitForTaskCompletion(...)`. Refer [this](https://github.com/yugabyte/ybm-cli/blob/c24aca2700307de5d8f91735e9e75659f1c25847/cmd/cluster/log-exporter/query_log_exporter.go#L251) for example.
+
+### 2. Testing
+
+- **Unit Tests**: Write unit tests for the command including but not limited to:
+  - [ ] A test case for required params not provided. 
+  - [ ] A test to assert Table output format. 
+  - [ ] A test to assert Json output format. 
+  - [ ] When mocking an API call, verify that the call was actually made. For example, use `Expect(server.ReceivedRequests()).Should(HaveLen(1))`. For `POST`, `PUT`, or `PATCH` requests, you can also assert the request body content as follows:
+    ```shell
+    server.AppendHandlers(
+      ghttp.CombineHandlers(
+        ghttp.VerifyRequest(http.MethodPut, "/some/path"),
+        # Here we are asserting on the expected Request Body
+        ghttp.VerifyJSON(`{"expectedField1":"val1",...}`),
+        ghttp.RespondWithJSONEncodedPtr(&statusCode, resp),
+      )
+    )
+    ```
+    This approach is useful for confirming that all necessary fields were included when building the request model, helping catch any omissions in the request structure.
+
+- **Run Tests**: Execute the test suite and verify all tests pass.
+
+### 3. Documentation
+To generate doc, run:
+```shell
+cd ~/code/ybm-cli/
+make doc
+```
+It will automatically generate document for each subcommand.
