Kerno

Kerno is a validation engine designed for agentic coding workflows, ensuring that AI agents do not introduce breaking backend changes or unintended side effects during each session. It continuously monitors and validates the impact of code generated or modified by agents against live or staged backend environments. The primary purpose of Kerno is to provide a safety and quality layer that preserves system integrity while enabling faster, more autonomous development with AI-driven tools.

Kerno tracks dependencies across services, APIs, and data models, detecting when a generated change could break existing contracts, workflows, or integrations. It validates assumptions made by agents against real backend behavior, surfacing discrepancies early in the development loop. The tool can automatically flag regressions, incompatible schema changes, or behavioral shifts in critical endpoints, providing developers with precise diagnostics. By embedding this validation inside every agent session, Kerno enables safer iterative experimentation without sacrificing reliability or observability.
