# Grow the Knowledge Base

> Capture a lesson, decision, or resource so future grounding is richer.

How your brand gets smarter over time. The knowledge base is most valuable when it grows as you work.

<Steps>
  <Step title="Notice the moment">
    After a decision, a result, or a shared resource, your agent offers to remember it.
  </Step>

  <Step title="Add it">
    `add_brand_knowledge` with the right source: `text` for a lesson or decision, `url` or `youtube` for a resource, `file` or `fileUrl` for a document or media. Confirm first, and give it a clear title.
  </Step>

  <Step title="Confirm">
    Your agent tells you it is now searchable. Future Ground steps surface it via `search_brand_knowledge`.
  </Step>
</Steps>

Good moments to capture: a brand decision ("we learned short hooks outperform for us"), a competitor teardown (a URL), or a brand guidelines document (a file). Adding needs `brandkit:write`. Remove an item with `remove_brand_knowledge` on request. See [Brand](/guides/brand).
