SkillBrew: Multi-Objective Curation of Skill Banks for LLM Agents

arXiv:2605.29440v1 Announce Type: cross Abstract: Retrieval-augmented LLM agents increasingly rely on curated skill banks: collections of reusable textual principles that guide decision making on complex tasks. Existing approaches typically expand these banks in an append-only fashion, continuously adding new skills without removing redundant, outdated, or harmful ones, resulting in inefficient and poorly curated repositories. In this paper, we formulate the skill bank curation as a constrained multi-objective problem: a desirable bank must be useful for the agent, diverse in its content, and

Why this matters
Why now

The proliferation of LLM agents and their increasing complexity necessitates effective methods for managing their underlying knowledge and skill bases.

Why it’s important

Efficient and well-curated skill banks are critical for scaling agentic AI, reducing operational overhead, and ensuring reliable decision-making in complex tasks.

What changes

This research introduces a structured, multi-objective approach to skill bank curation, moving beyond simple 'append-only' methods to enable more sophisticated management of agent capabilities.
