Create a signing key with constraints. Your agent can only act within the boundaries you set.

Git commits, SAFE agreements, NDAs, any payload. Your agent signs through sshsign with every action logged to an immutable audit trail.

For high-stakes actions, require human co-sign. Review the terms and approve with a handwritten signature in your browser.

Every signature is cryptographically verifiable. Every approval is sealed in a tamper-evident evidence envelope. Every negotiation round is chain-linked and immutable.
