This appears to be a legitimate browser automation skill, but it gives an agent broad control over logged-in browsing data and saved session artifacts without enough safety boundaries.
Install only if you need agent-driven browser automation. Use isolated browser profiles or test accounts when possible, verify or pin the external npm package, and require explicit approval before reading cookies/storage, saving or loading auth state, exporting screenshots/traces/recordings/PDFs, uploading files, submitting forms, or using this on sensitive logged-in accounts. Delete saved auth files and captured artifacts when finished.
