Can't be undone 1Claude Code: ask
  • take_screenshotCapture a screenshot of a public web page (http/https).1 finding

    Why it is in this group

    • The name "take_screenshot" says "screenshot": a word for reading.
    • The description's first verb is "capture": a word that usually means money moves, which cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
