What is skill library?
Skill library: A growing collection of reusable code or instruction packages an agent has learned or been given, which it can retrieve and apply to new tasks. It lets an agent build on earlier successes instead of solving every problem from scratch.
Skill library: an example
An agent stores a tested function 'export_to_csv' and reuses it in later tasks.
