-Using the `.quickAction()` method requires setting your Worker's compatibility date to `2026-03-24` or later in your `wrangler.json`:
+The `.quickAction()` method has two requirements:
+
+- **Compatibility date:** Your Worker must use a compatibility date of `2026-03-24` or later.
+- **Remote mode for local development:** The `.quickAction()` method is not yet supported in local development mode. When developing locally with `wrangler dev`, you must use `npx wrangler dev --remote` or set `"remote": true` in your browser binding configuration. Without remote mode, you will receive the error: `The RPC receiver does not implement the method "quickAction"`.

+
+The `.quickAction()` method is not yet supported in local development mode. When using `wrangler dev`, you must run with `--remote` or set `"remote": true` in your browser binding configuration:
+
+```jsonc
+{
+  "browser": {
+    "binding": "MYBROWSER",

+
+Without remote mode, calls to `.quickAction()` will fail with: `The RPC receiver does not implement the method "quickAction"`.

+
+For Puppeteer, Playwright, or CDP-based Workers, run `npx wrangler dev` to test locally. For Quick Actions via `.quickAction()`, use `npx wrangler dev --remote` as noted above.
