+### Configure custom instructions
+
+The Dev Agent ingests custom instruction files from your repository, including:
+
+- `.cursorrules`
+- `.windsurfrules`
+- `copilot-instructions.md`
+- `CLAUDE.md`
+- `AGENTS.md`
+- `agent.md`

 ### Configure internet access
 
-To configure which external domains agents can reach during agent execution, navigate to **Bits AI Dev** > [**Settings**][12] > **General**, and find the **Internet Access** section. Choose from the following access policies: **No Internet Access**, **Default Allowlist**, **Custom + Default Allowlist**, or **Custom Allowlist**.
+By default, the Dev Agent has **no internet access** during agent execution.
