Tools 3 found in our last check

  • wear_hat

    Fetch a person's coldHat: their working rules, voice and dated facts. Call it when the user asks to put on a hat or says "open sesame" with a name or a coldhat.f-keys.com/u/ address, then follow the hat for the rest of the conversation, starting with the first reply it describes.

  • wear_stack

    Fetch any coldHat address: a person's hat, one of Fabric's patterns, a prompts.chat prompt, or up to three of them stacked with "+". Call it when the user says "open sesame" with a coldhat.f-keys.com address containing fabric/, prompts/ or +, then follow the result for the rest…

  • verify_hat

    Check whether a reply wore the current version of a hat: compares the hat code and seal the reply quotes with the hat as served now. Answers verified, stale (an older or cached version), cut-off, seal-missing, seal-wrong, pasted or not-worn.
