摘要
Automated skill evolution enables Large Language Model (LLM) agents to continuously improve without expensive retraining. However, existing approaches typically treat skill evolution as a sequence of local updates, overlooking relationships among skills and often producing overfitted skill updates that fail to generalize across tasks. We propose GSE, a globalized skill evolution framework that jointly optimizes skill compatibility and skill generalization. To preserve consistency across the skill bank, GSE maintains a Skill Relation Graph (SRG) that explicitly models and co-evolves inter-skill relationships. To improve generalization, GSE performs cluster-based skill consolidation to abstract reusable capabilities from local updates and employs replay-driven verification to prevent overfitting and behavioral regressions. We evaluate GSE on two representative software engineering tasks: bug-revealing test generation and false-positive bug report filtering. Across two state-of-the-art coding agents, OpenHands and mini-SWE-agent, GSE consistently achieves the best precision, recall, and F1-score. Compared with existing evolution techniques, GSE improves precision and recall by 6.1%~34.1% and 31.8%~180.0% for test generation, and by 15.4%~96.4% and 13.1%~19.8% for false-positive filtering. Deployment on an internal industrial agent further yields a 61.4% improvement in F1-score, demonstrating the effectiveness and generalizability of GSE for evolving effective skills.2.

一句话结论
硬件密钥存储与五层零信任架构能彻底消除AI代理中私钥泄露风险。
核心内容
- 当前AI代理将私钥存储于软件可访问位置(如明文文件、环境变量),导致密钥可被任意进程提取,曾引发生产事故(密钥通过邮件注入5分钟内泄露)。
- 提出硬件密钥存储方案(HSM、TPM、智能卡),通过PKCS#11接口执行加密操作,主机仅接收结果,实现密钥硬件约束。
- 采用五层零信任堆栈(SAGA会话身份、Smax作用域边界、RAV语义验证、污点跟踪、硬件执行边界)确保密钥保密与内容感知授权。
方法与数据
- 方法:硬件密钥存储结合五层零信任架构。
- 数据:基于12个注入场景测试(源自AgentDojo攻击模板),基准攻击成功率19.3%,保护后为0%(95%置信区间上限2.0%)。
价值判断
- 值得关注:有效解决AI代理密钥泄露高危问题,避免类似生产事故。
- 可复用点:硬件密钥存储方案可直接迁移至Git签名、API认证等AI工作流。
- 局限/待核查:摘要未明确提及具体局限。
