# Preprint reports multi-stage security gateway for coding agents

_Published Monday, August 24, 2026 at 8:07 AM EDT · Science, Security · Latest · Tier 2 — Notable_

An arXiv preprint describes ClawSentry, an open-source security supervision gateway for agent runtimes that reviews skills before use and applies progressive checks during and after tool activity. The authors report that its deterministic, semantic-review and read-only evidence-seeking layers reduced contextual attack-success rates in their SkillInject tests while retaining clean-skill task success. The system also uses session-level checks intended to recognize tool switching and rephrased retries. Those results are preprint claims, not independent validation of production protection.
