To debug an Add-in Command, you must run it in Office Online. For details, see Debug add-ins in Office Online.
Apply the following best practices when you develop add-in commands:
Use commands to represent a specific action with a clear and specific outcome for users. Do not combine multiple actions in a single button.
Provide granular actions that make common tasks within your add-in more efficient to perform. Minimize the number of steps an action takes to complete.
For the placement of your commands in the Office ribbon:
- Place commands on an existing tab (Insert, Review, and so on) if the functionality provided fits there. For example, if your add-in enables users to insert media, add a group to the Insert tab. Note that not all tabs are available across all Office versions. For more information, see Office Add-ins XML manifest.
- Place commands on the Home tab if the functionality doesn't fit on another tab, and you have fewer than six top-level commands. You can also add commands to the Home tab if your add-in needs to work across Office versions (such as Office Desktop and Office Online) and a tab is not available in all versions (for example, the Design tab doesn't exist in Office Online).
- Place commands on a custom tab if you have more than six top-level commands.
- Name your group to match the name of your add-in. If you have multiple groups, name each group based on the functionality that the commands in that group provide.
- Do not add superfluous buttons to increase the real estate of your add-in.
Add-ins that take up too much space might not pass AppSource validation.
For all icons, follow the icon design guidelines.
Provide a version of your add-in that also works on hosts that do not support commands. A single add-in manifest can work in both command-aware (with commands) and non-command-aware (as a task pane) hosts.

The best way to get started using add-in commands is to take a look at the Office Add-in commands samples on GitHub.
