A knowledge worker notices that a Claude output may have repeated a confidential financial figure...

Option A is the appropriate containment and reporting response. The appearance of restricted information in a generated output indicates a possible data-handling or access-control failure. The user should stop the output from progressing, preserve enough information to investigate what occurred, and follow the organization’s established governance or security incident procedure. Relevant evidence normally includes the prompt, generated response, implicated source, users or systems involved, and whether any further distribution occurred.

Deleting the figure from the visible output, as suggested in Option B, does not address how the restricted information entered the workflow or whether it remains present in conversation history, logs, connected sources, or other generated material. A personal log is not a substitute for the approved reporting mechanism. Starting a new chat under Option C may prevent additional use of that conversation but does not remediate or report the original incident. Option D incorrectly assumes that an internal exposure is harmless. Organizational confidentiality requirements can be violated even before information is distributed externally.

Claude users remain accountable for applying data classifications, limiting sensitive inputs, reviewing generated outputs, and escalating suspected exposure through authorized channels. Early reporting enables containment and corrective action.
