Short answer: the dashboard won’t let you delete a document if any agent still depends on it. To remove it anyway, use the API’s force delete.
What to do
In the dashboard, open the document and check the “Agents” tab to confirm there are no dependent agents. If any are listed, remove the document from those agents first. (elevenlabs.io)
If you want to delete it regardless of dependencies, call:
DELETE /v1/convai/knowledge-base/:documentation_id?force=true
This removes the document and detaches it from all dependent agents. (elevenlabs.io)
If you’re unsure which agent still references it, query:
GET /v1/convai/knowledge-base/:documentation_id/dependent-agents
to list any remaining dependencies. (elevenlabs.io)
