Zero False Green Verify
Claude connectorCommunityVerify ZFG signed receipts and check whether a git commit has a signed GREEN, right inside Claude.
Zero False Green (ZFG) gives AI-built software proof, not claims: a GREEN only counts when real checks ran and passed for the exact code. This connector lets Claude verify ZFG evidence in conversation.
Tools (all read-only):
- verify_receipt: confirms a ZFG signed receipt is genuine and unchanged, and shows what it attests (verdict, project, git commit, signing time, CI source, test or live mode).
- check_merge_gate: says whether a receipt is a valid live-mode signed GREEN for an exact 40-character commit SHA, the same rule as the ZFG GitHub merge gate.
- list_signing_keys: lists ZFG's public Ed25519 signing keys so anyone can verify signatures independently.
- about_zfg: explains the verdicts (GREEN, RED, BLOCKED) and exactly what a signature does and does not prove.
No sign-in and no account needed. It returns only what a public ZFG verification link already shows, never account, billing or key details, and it cannot change anything. A valid signature proves origin and integrity; it is not a security audit or release approval.
