What the publisher says
From the VouchSpec Agent Skill Evidence repository's README, as published. We do not edit it. Read it on GitHub
VouchSpec
VouchSpec is the provisional public-beta name for an independent evidence index for exact Agent Skill versions. The name passed a $0 obvious-conflict screen; it has not received formal legal or trademark clearance.
The current Stage A catalog contains 25 deliberately selected public Agent Skills across 12 GitHub repository owners. Every entry is pinned to a full Git commit and exact directory digest, statically inspected without executing artifact code, wrapped in a DSSE v1.0.2 envelope, and signed with Ed25519. A separate root key signs the machine-readable lifecycle feed.
This is evidence, not a safety certification. Six of the 25 real-world skills fail at least one current structural rule; they remain indexed with the failure evidence and are not labeled STRUCTURE_VALIDATED.

- Out-of-band root/issuer key publication:
The static distribution returns the exact checked-in signed bytes with CORS enabled and rejects writes. Download the signed index, filter it locally, then retrieve a receipt by ID from catalog/public/receipts/. For immutable retrieval, replace main with catalog snapshot 4404b7a9a2d3dc45b621ea694d2ca7ad666b9898. The out-of-band Gist is separate from the repository but shares its GitHub account, so an account-level compromise still requires a new trusted channel.
