Replicate its body instead (below). +* `aaz-dev command-model generate-from-swagger` builds a **brand-new default tree** + (`Commands/event-hub/`) and edits `Commands/readme.md` - it ignores your curated + `Commands/eventhubs/`. Revert and use `WorkspaceManager` directly. +* The package is **not** importable as `aaz_dev.*`.

Merge them before saving, or the CLI gets a second top-level command group: + +```python +ws.rename_command_tree_node(*old_names, new_node_names=["eventhubs", ...]) +ws.delete_command_tree_node("event-hub") +``` + +**Always dry-run first** (`folder=WorkspaceManager.IN_MEMORY`) and print the resulting leaf names; +confirm every leaf starts with the real service name and nothing was renamed. + +**Step 2 - generate the CLI module** by replicating `cli.api._cmds.generate_by_swagger_tag`: + +```python +from cli.api._cmds import _build_profile +from cli.controller.az_module_manager import AzMainManager # NOT cli.controller.az_main_manager +commands_map = {} # {(cmd, names, tuple): version} +for rid, vmap in rp.get_resource_map_by_tag(TAG).items(): + reader = aaz.load_resource_cfg_reader(Config.DEFAULT_PLANE, rid, list(vmap)[0]) + for names, command in reader.iter_commands(): + commands_map[tuple(names)] = command.version +profile = _build_profile(Config.CLI_DEFAULT_PROFILE, commands_map) +mgr = AzMainManager(); module = mgr.load_module(service) +module.profiles[profile.name] = profile +mgr.update_module(service, module.profiles) +``` + +**Step 3 - filter the command surface (MANDATORY).** `_build_profile` emits **every** command in +the tag, including ones the module has never shipped. Some will **shadow hand-written custom +commands** (`namespace identity assign/remove/show` collide with `commands.py`). Before generating: + +```powershell +# commands the tag would add that are not currently shipped +git -C $CLI ls-files "*//aaz/latest/*" # compare against the generated command list +grep -n "custom_command" $CLI\src\...\\commands.py +``` +Build an `EXCLUDE` set of those command-name tuples and skip them in the loop. Adding a brand-new +command group is fine and expected; **silently replacing a custom command is not** - `EXCLUDE` it +and say so in the report. That is a section 8.2 decision you make yourself, not a question. + +To patch a model by hand, edit the **`.json`** (`load_resource_cfg_reader` uses it; the `.xml` is a +byproduct) then persist through the manager so `.xml` and `.md` stay consistent: +`CMDConfiguration(data)` -> `AAZSpecsManager.update_resource_cfg(cfg)` -> `.save()`. +Never hand-edit the `.xml`; it can contain unescaped `<` (e.g. `type="array"`) that breaks +`lxml`. + +--- + +## 6. FROZEN: `_failover.py` (api-version bump ONLY) + +Files: `/aaz/latest//namespace/_failover.py` for **both** servicebus and eventhubs. + +**Only the API version string may change.** Class name, `@register_command`, `AZ_SUPPORT_NO_WAIT`, +the arg schema (`--namespace-name`, `--resource-group`, `--force`, `--primary-location`), arg +groups, help text, LRO config (`final-state-via: azure-async-operation`), status codes +(`[202]` and `[200, 201]`), content builder and response schema stay **byte-identical**. +*Why:* failover is hand-tuned; swagger emits a wrong LRO shape/status set and drops `--force` / +`--primary-location`, breaking `az namespace failover` in the field. + +**Procedure:** snapshot (section 4) -> generate -> `Copy-Item` the `.bak` back over the generated +file -> replace exactly **3** version literals per file: + +| # | Location | Change | +|---|---|---| +| 1 | `_aaz_info["version"]` | `"version": ""` -> `""` | +| 2 | `_aaz_info["resources"]` tuple | trailing `""` -> `""` | +| 3 | `serialize_query_param("api-version", ...)` | `""` -> `""` | + +Use `multi_replace_string_in_file`; never a whole-file rewrite; preserve line endings. + +**Verify:** `git -C $CLI --no-pager diff -- "*/namespace/_failover.py"` must show **at most 3 +`-`/`+` pairs per file**. Anything else => restore the `.bak` and redo. + +Never remove `--force`/`--primary-location`. Never add new failover args even if `` declares +them - **silently dropping them is the correct default**; mention it in the report and only +`ask_user` if the user has said they want the failover surface extended. In the aaz model +(`Commands//namespace/_failover.md`) the only change is a **new version entry appended** +to `## Versions`; existing entries are never edited or removed. + +--- + +## 7. Reconcile the hand-written custom layer + +Generated code is only half the command.

Never +stop at the generated layer. + +### 7.2 House-style precedents + +**`operations/namespace_custom.py`** - build `command_args_dict`, call the generated class: +```python +from azure.cli.command_modules.servicebus.aaz.latest.servicebus.namespace import Create +command_args_dict = {"resource_group": resource_group_name, "namespace_name": namespace_name, + ..., "ip_address_type": ip_address_type} # new scalars here +return Create(cli_ctx=cmd.cli_ctx)(command_args=command_args_dict) +``` +Nested blocks (`identity`, `encryption`, `geo_data_replication`) are added via +`command_args_dict.update({...})` **only when supplied** - keep that conditional shape so `None` +never wipes server state. The merge helpers (`cli_add_encryption`, `cli_remove_encryption`, +`cli_add_identity`, `cli_remove_identity`, `cli_add_location`, `cli_remove_location`) `Show()` -> +merge -> `Update()`; a new sub-property must also be carried in `create_keyvault_object` / +`create_replica_location_object`, or every add/remove silently drops it. + +**`_params.py`** - registers args **per command scope** (create-only under +`'servicebus namespace create'`; shared under the parent `'servicebus namespace'`). Enums use +`get_enum_type()`, booleans `get_three_state_flag()`, tags `tags_type`. Keep short aliases - +customers script against them: +```python +c.argument('premium_messaging_partitions', is_preview=True, type=int, + options_list=['--premium-messaging-partitions', '--premium-partitions'], help='...') +c.argument('geo_data_replication_config', action=AlertAddlocation, nargs='+', + options_list=['--geo-data-replication-config', '--replica-config'], help='...') +``` + +**`action.py`** - structured args use `_AppendAction` subclasses that parse `k=v`, snake_case the +keys, enforce mandatory keys and default the optional ones (`AlertAddEncryption`, +`AlertAddVirtualNetwork`, `AlertAddIpRule`, `AlertAddlocation`). A new sub-property needs: +(1) a new `elif k == '':` branch, (2) the `InvalidArgumentValueError` allowed-keys +message updated (commonly forgotten), (3) a mandatory (`CLIError`) or default decision. + +**`commands.py`** - only custom commands are registered; AAZ commands auto-load. Preserve +`supports_no_wait=True`, `confirmation=True`, `validator=` exactly, and point the +`CliCommandType` `operations_tmpl` at the right `operations/*.py`. + +### 7.3 SB <-> EH parity + +The modules mirror each other (`create_servicebus_namespace` <-> `create_eventhub_namespace`, +same keyvault/replica helpers, identity, encryption, network rule sets, private endpoint +connections, georecovery aliases).
