## Limitations

Source and npm release metadata for webmarker-js 0.7.0 are public. The documented mark/unmark API supports screenshot prompts and Playwright interaction, but this utility is not itself a language model or autonomous agent. The WebVoyager/Set-of-Mark references are usage inspiration and are not asserted as papers introducing this library. No package was installed or executed.
