    "incantation": "When resuming work across browser restarts, use `--session-name` to persist cookies and localStorage; set an encryption key to encrypt saved state. When a click should open its link in a separate tab, add `--new-tab`.",

      "Version: v0.10.0",
      "--session-name <name>: Name for automatic saved-state persistence. Current docs mark this as legacy; they document `--restore` with a stable `--session` for automatic persistence.",
      "AGENT_BROWSER_ENCRYPTION_KEY: 64-character hexadecimal key; when set, encrypts saved state with AES-256-GCM. Generate with `openssl rand -hex 32`.",
      "click <selector> --new-tab: `<selector>` identifies the element to click; `--new-tab` opens the link in a new tab.",
      "state show <file> (required): File to show a saved-state summary for.",
      "state rename <old-name> <new-name> (required): Existing state name and replacement name.",
      "state clear <name>: Session name whose saved states to clear; `--all` clears all saved states.",
      "state clean --older-than <days> (required): Delete saved states older than the specified number of days.",
      "Docs conflict: The current sessions documentation describes `--session-name` as legacy and recommends `--restore` with a stable `--session` for persistence; this differs from the v0.10.0 release note."
