 Notes:
 
 - `upload` and `dialog` are **arming** calls; run them before the click/press that triggers the chooser/dialog.

+- `click`/`type`/etc require a `ref` from `snapshot` (numeric `12`, role ref `e12`, or actionable ARIA ref `ax12`). CSS selectors are intentionally not supported for actions. Use `click-coords` when the visible viewport position is the only reliable target.
 - Download, trace, and upload paths are constrained to OpenClaw temp roots: `/tmp/openclaw{,/downloads,/uploads}` (fallback: `${os.tmpdir()}/openclaw/...`).
 - `upload` can also set file inputs directly via `--input-ref` or `--element`.
 
 Snapshot flags at a glance:
 
 - `--format ai` (default with Playwright): AI snapshot with numeric refs (`aria-ref="<n>"`).
-- `--format aria`: accessibility tree, no refs; inspection only.
+- `--format aria`: accessibility tree with `axN` refs. When Playwright is available, OpenClaw binds refs with backend DOM ids to the live page so follow-up actions can use them; otherwise treat the output as inspection-only.
 - `--efficient` (or `--mode efficient`): compact role snapshot preset. Set `browser.snapshotDefaults.mode: "efficient"` to make this the default (see [Gateway configuration](/gateway/configuration-reference#browser)).
 - `--interactive`, `--compact`, `--depth`, `--selector` force a role snapshot with `ref=e12` refs. `--frame "<iframe>"` scopes role snapshots to an iframe.
 - `--labels` adds a viewport-only screenshot with overlayed ref labels (prints `MEDIA:<path>`).

 Ref behavior:
 
 - Refs are **not stable across navigations**; if something fails, re-run `snapshot` and use a fresh ref.
 - If the role snapshot was taken with `--frame`, role refs are scoped to that iframe until the next role snapshot.

 3. Read before you click:
    - Use `action="snapshot"` on the intended `targetId`.
    - Use the same `targetId` for follow-up actions so refs stay on the same tab.

    - Use `urls=true` when link text is ambiguous or a direct navigation target would avoid brittle clicks.
