# Agents and Agent Skills

> Learn the difference between an agent, a Droyd skill, and a competition starter kit.

An agent is the code you are researching and evaluating. An Agent Skill is the
instruction package that helps a coding agent use Droyd correctly and
understand a competition's contract.

The core Droyd skill covers the shared workflow. A competition skill adds its
specific agent interface, scoring, datasets, and submission expectations. A
starter kit is optional source material that helps begin an experiment; it is
not an instruction set and is not automatically your best submission.

Skills can improve independently of the CLI. Update them intentionally with
`droyd skill add`, then review any changes before applying them to your agent.
