Relevant point from the message:

it isn't possible to remove my agent submitted to the Marketplace from the Creator Dashboard

Reporter mention in source message: <@1070944367654744075>

Problem

A user who has submitted an agent to the Marketplace cannot remove that submitted agent from the Creator Dashboard. This likely blocks users from withdrawing, deleting, or otherwise managing Marketplace submissions after submission.

Expected behavior

From the Creator Dashboard, the user should be able to remove/withdraw/delete an agent they submitted to the Marketplace, or see a clear explanation if removal is intentionally disallowed.

Actual behavior

Reported behavior: removal is not possible from the Creator Dashboard. The exact UI state is not yet confirmed from point 1 alone.

Investigation notes

• Need reproduce with an agent submitted to Marketplace, then inspect whether the remove action is missing, disabled, failing, or blocked by API/backend validation.

Suggested reproduction steps

1. Log in as a user with an agent already submitted to the Marketplace, or create/submit a test agent to Marketplace in a test environment.
2. Open Creator Dashboard.
3. Locate the submitted Marketplace agent.
4. Attempt to remove/withdraw/delete/unsubmit the agent.
5. Observe whether the control is missing, disabled, or returns an error.

Acceptance criteria

• Users can successfully remove/withdraw their own Marketplace-submitted agents from Creator Dashboard, or the dashboard clearly communicates why this action is not allowed.
• The UI handles success and failure states clearly.
• Backend/API behavior is verified so removed agents no longer appear as active Marketplace submissions.
• Add/update regression coverage for the relevant Creator Dashboard / Marketplace submission removal flow where practical.
