Signetry is live 🪪 — what it is, install, and how to contribute

Signetry is live. 🪪

Signetry is a change-control plane for coding agents — it decides how much authority an agent's change earned, and seals the verdict in an Ed25519-signed receipt. A signet is the seal that authenticates a document; Signetry seals a verified change.

Any agent (Claude Code, Codex, Cursor, Copilot — or a human) may propose a change. Only Signetry decides whether it's admitted, running one deterministic pipeline: executable contract → untrusted-text quarantine → required checks → independent verifier → earned authority → signed receipt. auto_merge is always false — a human merges.
