Change a Sidekick avatar
Change a Sidekick avatar in Cortex Chat: practical steps, setting explanations, result checks and troubleshooting.
A custom avatar helps distinguish assistants, especially when several have similar roles. The default artwork can change with runtime state, so replacing it is an identity choice rather than a repair for an activity problem.
Before you start
The Sidekick identity, role description, runtime and tool policy describe different things. Name and artwork identify the assistant. Skills and job tell it how to approach work. Sessions determines whether its runtime is available, and saved tool settings determine the operations it can use. An assistant can therefore have a clear job but still be offline or lack a required app permission. Diagnose the specific layer before restarting or replacing it. In particular, removal is not a harmless refresh: the confirmation explains that the transcript is permanently deleted. Preserve the work you need through an appropriate authorised artifact before a destructive action.
Step-by-step
- Open the Sidekick avatar control in Manage Sidekicks or the selected conversation.
- Choose a supported image through the upload control and read any size or format validation.
- Confirm the saved image appears on the intended assistant in the list and conversation.
What the settings mean
| Control or state | Meaning |
|---|---|
| Role | Instructions and specialisation, not automatic credentials. |
| Runtime | Starting, working, restarting and other current availability signals. |
| Default | An account preference used for an implicit assistant selection. |
| Tool policy | Saved allowed operations for the relevant context. |
Check the result
The selected Sidekick uses the intended image without exposing a private face, customer logo or document in a public example.
If it does not work
If the preview fails, use the exact validation message and retry with a suitable image. Do not assume a local file preview means the upload was saved.
Continue with the right context
