PromptSign ★ 0
PromptSign verifies cryptographic signatures on Claude Code instruction files (CLAUDE.md, skills, and agent definitions) using Sigstore keyless infrastructure before they reach model context. It re-checks skill bundles at runtime and blocks tampered files, with offline verification against a pinned trust root and no telemetry.
