COBRA-Skills: Contextual Bandit-Guided Evolution for Agent Skill Optimization

Pingchen Lu, Xiangyi Wang, Xiang Li, Jie Mao, Zikun Qu

OBRA-Skills optimizes LLM agent skills by treating it as a budgeted sequential optimization problem. It uses a contextual bandit to guide the selection of skills for evaluation, prioritizing promising or informative candidates. This approach efficiently refines the skill population using execution feedback, significantly reducing optimization costs and data requirements while achieving superior performance across diverse benchmarks.

Overview of COBRA-Skills. At each round, skills in 𝒫 t \( \mathcal{P}_{t} \) are prioritized using a neural reward predictor and LinearUCB bonus based on ℋ t − 1 \( \mathcal{H}_{t-1} \) (\( \scriptsize \)1⃝), and the highest-priority skill is evaluated by the target agent (\( \scriptsize \)2⃝). The resulting reward and trajectories update the optimization history and scoring model (\( \scriptsize \)3⃝). At scheduled population updates (performed periodically rather than after every round), new skills are evolved from accumulated evidence (\( \scriptsize \)4⃝), and the updated priority scores from \( \scriptsize \)1⃝ identify low-priority skills, which are replaced by the newly evolved skills to form 𝒫 t + 1 \( \mathcal{P}_{t+1} \) (\( \scriptsize \)5⃝). Dashed borders and arrows indicate scheduled-only operations.

Functional architecture of the artificial id. Current language models provide the general reasoning associated here with the ego. The experiment isolates a minimal adaptive drive whose behavior is shaped through differential persistence in an environment. In the proposed coupled architecture, the id influences what the system continues to pursue, the ego translates that state into task-specific reasoning and action, and the resulting changes to the system and its environment become new input to the id. The right panel situates this loop within a persistent alignment boundary. Across the proposed architecture, that boundary comprises trusted observations, consequence channels, persistent state, authority, identity, provenance and hard constraints. Variation and differential persistence are the learning mechanism used in the experiment to produce adaptive drive; they are not required components of the proposed deployed id. The integrated architecture is proposed and is not tested here.

Artificial Id: Drive and Persistent Alignment in Agentic AI

Yakov Pyotr Shkolnikov

This paper introduces an "artificial id" as an internal, adaptive drive for agentic AI systems. This mechanism allows agents to autonomously decide when to continue, stop, or change their behavior, moving beyond externally defined control. The core contributio…
