# Capture & sessions

> Trace agent work; capture durable knowledge as drafts.

<Warning>
  **Early access** — Treat captures as drafts until you commit per governance. [**Join the Product Brain Community**](https://community.productbrain.io).
</Warning>

**You:** “Start a session,” “capture this decision,” “close the session.” **Your agent:** `pb session start`, `pb capture "…"`, `pb session close` or MCP session tools.

See [MCP Session tools](/docs/mcp/session-tools) and [The Loop](/docs/method/overview).
