What you'll learn
Turn a recurring mistake into a testable skill

Compare your agent with and without the skill
Build a small evaluation using realistic tasks and executable checks
Decide which changes are worth keeping
Understand the effectiveness of your skills and different models using metrics such as: task success, time, and cost
Why this topic matters
You add a skill. Rewrite your project instructions. Try a different model. However You can't tell if your coding agent is actually producing bette results.
In this lesson, we'll work through a coding example, turn an observed failure into a focused skill, and compare versions using a simple evaluation. You'll get the tools to decide whether your change actually made your agent better as agents models and skills constantly change and evolve.
