+### Bind mounts (security quick check)
+
+- `docker.binds` *pierces* the sandbox filesystem: whatever you mount is visible inside the container with the mode you set (`:ro` or `:rw`).
+- Default is read-write if you omit the mode; prefer `:ro` for source/secrets.
+- `scope: "shared"` ignores per-agent binds (only global binds apply).
+- Binding `/var/run/docker.sock` effectively hands host control to the sandbox; only do this intentionally.
+- Workspace access (`workspaceAccess: "ro"`/`"rw"`) is independent of bind modes.

 ## Tool policy: which tools exist/are callable
 
 Two layers matter:

 Global and per-agent binds are **merged** (not replaced). Under `scope: "shared"`, per-agent binds are ignored.
 
+Example (read-only source + docker socket):
+
+```json5
+{
+  agents: {
+    defaults: {
+      sandbox: {
+        docker: {

+        }
+      }
+    ]
+  }
+}
+```
+
+Security notes:
+- Binds bypass the sandbox filesystem: they expose host paths with whatever mode you set (`:ro` or `:rw`).
+- Sensitive mounts (e.g., `docker.sock`, secrets, SSH keys) should be `:ro` unless absolutely required.
+- Combine with `workspaceAccess: "ro"` if you only need read access to the workspace; bind modes stay independent.
+- See [Sandbox vs Tool Policy vs Elevated](/gateway/sandbox-vs-tool-policy-vs-elevated) for how binds interact with tool policy and elevated exec.

 Yes. See [Sandboxing](/gateway/sandboxing). For Docker-specific setup (full gateway in Docker or sandbox images), see [Docker](/install/docker).
 
+### How do I bind a host folder into the sandbox?
+
+Set `agents.defaults.sandbox.docker.binds` to `["host:path:mode"]` (e.g., `"/home/user/src:/src:ro"`). Global + per-agent binds merge; per-agent binds are ignored when `scope: "shared"`. Use `:ro` for anything sensitive and remember binds bypass the sandbox filesystem walls. See [Sandboxing](/gateway/sandboxing#custom-bind-mounts) and [Sandbox vs Tool Policy vs Elevated](/gateway/sandbox-vs-tool-policy-vs-elevated#bind-mounts-security-quick-check) for examples and safety notes.
