    "incantation": "When your workflow needs a Browser Rendering DevTools session, use `wrangler browser create`, `close`, `list`, or `view` with the options below. Use `--json` for programmatic output; use `--no-open` to print the DevTools URL without opening it.",
    "examples": [
      "wrangler browser create [--lab] [--keepAlive <seconds>] [--open] [--json]",
      "wrangler browser close <sessionId> [--json]",
      "wrangler browser list [--json]"
    ],
    "gotchas": [
      "Version: 4.82.0",
      "`<sessionId>` (required): Session to close.",
      "`[sessionId]`: Session to view; optional when only one session exists. `view` prompts when multiple sessions are available.",
      "`--lab`: Enable a lab browser session.",
      "`--keepAlive <seconds>`: Set session keep-alive duration; the 4.82.0 changelog documents an example of 300 seconds.",
      "`--open` / `--no-open`: Control whether DevTools opens in a browser; `--no-open` prints the DevTools URL. Default is true interactively and false in CI/scripts.",
      "`--target <selector>`: Select a target for `view`.",
      "`--json`: Return programmatic JSON output.",
      "Prerequisite: `wrangler login` adds the `browser:write` OAuth scope.",
      "Prerequisite: The Cloudflare changelog says Wrangler handles authentication, so API tokens need not be passed in the commands.",
      "The default for `--open` is true in interactive mode and false in CI/scripts.",
      "When multiple sessions exist, `view` prompts for selection.",
      "Docs conflict: The current Wrangler command docs describe Browser Run and omit `--no-open`; they also document `--keepAlive` as 60–600 seconds. These docs were last updated after Wrangler 4.82.0, so those details are not applied here: https://developers.cloudflare.com/workers/wrangler/commands/browser/"
