Guardrails apps

SoloKnuckle

Soloknuckle is an open source, fully local production hygiene layer that puts enforced guardrails inside AI coding agents. Secret scanning, a destructive command firewall, scope walls and a human review gate run on every agent edit, so nothing reaches main unchecked. The repository describes itself the same way: "An open source production hygiene layer built specifically for those who ship with and by agents."
