The Gate is the Boss: Building Trustworthy AI Coding Agents Through Systematic Oversight

Today's AI coding agents can produce syntactically correct code that introduces subtle architectural flaws—junior developer behavior with infinite confidence. O MASTO proposes a paradigm shift: instead of trusting agents or relying on fatigued human reviewers, implement multi-stage validation starting from read-only access through semantic gates, PR review, and test verification before code reaches main. As AI automation becomes ubiquitous, this safety-first architecture—where the gate, not the agent or reviewer, holds ultimate authority—may determine which teams ship resilient systems and which expose themselves to silent cascading failures.
