A pattern: a proof-of-human for un-quarantining feedback text.

· Bits and Bobs 8/10/26
  • A pattern: a proof-of-human for un-quarantining feedback text.
    • My little Floored Fitness app has a feature to allow users to add feedback.
    • I use it to give directives to my agents to add features, "programming" mostly by adding feedback.
    • Feedback from me (the admin) is safe, but feedback from anonymous third parties could be dangerous.
      • It could, for example, contain prompt injection.
    • That's why non-admin feedback goes into a quarantine, that a human has to drain and approve, after verifying there's no prompt injection in the input.
    • My agents were so eager to get at the 3rd party feedback that they looked at it themselves to verify it didn't have prompt injection, potentially tainting themselves.
      • D'oh!
    • I added a feature to the feedback tool: the human has to authenticate with TouchID before being able to see the quarantined feedback.
    • That helps prove that you're a human before seeing the potentially prompt injected input.
