java-mastery

Run an oral-style technical interview on a Java/Spring/system-design/DSA topic — ask questions one at a time, react to the answers, probe deeper, then give a debrief. Use when the user wants to practice answering interview questions out loud.

Generate a fresh Java coding exercise (stub + failing JUnit tests) on a given topic for the user to solve on their own, TDD-style. Use when the user asks for a new challenge, exercise, or technical test on any Java/Spring/DSA/design topic.

Unlock the next module in the java-mastery curriculum — write the theory README and create its starter exercises with failing tests. Use when the user finished a module and wants to progress, or asks to start a specific module.

Review the user's solution to a java-mastery exercise like a senior engineer / interviewer — run the tests, grade correctness, style, complexity, and idiomatic Java, then suggest improvements. Use after the user says they finished an exercise or module.
