Overview

AI summary

PromptSign.ai provides a way to sign and verify the integrity of skills, agents, and associated files used by AI systems. It emphasizes the provenance of these files by ensuring that they have not changed since being signed, allowing users to revoke trust in compromised publishers.

Sources behind this listingSee source links, recorded dates and owner corrections.

Observed facts come from public pages. Founder-edited facts are supplied by the verified owner. AI-inferred facts are model interpretations; derived facts are calculated from other data. A source link lets you check the current page. It does not guarantee the fact is still current.

Dates show when a record was saved. Some older records use the listing’s update date; they are not proof of a fresh check. Missing source records are shown explicitly.
