The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Skills are therefore central to the scalability, robustness, and maintainability of modern agent systems.

C2weakest assumption

That the proposed definition of agent skills as reusable procedural artifacts and the four-stage lifecycle accurately capture the key challenges and organize the relevant literature without significant omissions.

C3one line summary

The paper surveys agent skills for LLM agents, organizing the literature into a four-stage lifecycle of representation, acquisition, retrieval, and evolution while highlighting their role in system scalability.
