> ## Agent Instructions
> To search or read these docs, connect the Ringg docs MCP server at https://docs.ringg.ai/mcp (no key needed; tools search_ringg_ai and query_docs_filesystem_ringg_ai) instead of browsing pages one by one. Setup for each client: https://docs.ringg.ai/resources/mcp-server/docs-mcp-server/mcp-for-ai-assistants.md
> The dashboard labels agents "Assistants"; these docs say "agent". Both mean the same object, identified by agent_id.
> API base URL: https://prod-api.ringg.ai/ca/api/v0. Send the workspace API key in the X-API-KEY header, from server-side code only.
> Placing a call dials a real phone number and spends credits. Confirm the number with the user before calling.
> To act on a Ringg workspace (place calls, edit agents, read transcripts), use the separate Ringg workspace MCP server at https://mcp.ringg.ai/mcp: https://docs.ringg.ai/resources/mcp-server/workspace-mcp-server/overview.md

> Delete a knowledge base and all of its files, URLs and FAQs permanently; agents that use it stop answering from it at once, so detach or replace it first.

# Delete Knowledge Base

export const RelatedTopics = ({items}) => <div className="not-prose mt-12">
    <div className="text-sm font-medium text-gray-500 dark:text-zinc-400 mb-3">Related topics</div>
    <div className="flex flex-col gap-2.5">
      {items.map(([title, href]) => <a key={href} href={href} className="flex items-center gap-2.5 text-sm text-gray-700 hover:text-gray-950 dark:text-zinc-300 dark:hover:text-white">
          <Icon icon="file-text" size={16} color="currentColor" />
          {title}
        </a>)}
    </div>
  </div>;

Attach a replacement first with the `attach_kb` operation of [Edit agent settings](/api-reference/agents/edit-assistant). To change only some content, use [Edit knowledge base](/api-reference/inventory/knowledge-bases/edit-knowledge-base) instead; it keeps the `kb_id` and the agents attached.
