It supports Claude Code and Codex; pick AutoDefense if autoDefense uses a multi-agent framework to mitigate jailbreak attacks on LLMs, installed via Python. [prismor](https://prismor.dev) reports 280 GitHub stars, 26 forks, and 12 open issues, last pushed Aug 9, 2026. [AutoDefense](https://arxiv.org/abs/2403.04783) has 68 stars, 20 forks, and 1 open issues, last pushed Jan 15, 2026.
