Deterministic checks before AI

Local grading only

Tests decide pass/fail first using simple deterministic rules. Ada can explain failures later, but AI does not decide your score.

Mission Brief

Build a small PlayerCard that takes data through props and shows it.

Checklist

  • Create a PlayerCard component
  • Accept a name prop
  • Accept a level prop
  • Show the name on the card
  • Show the level on the card

Hint Ladder

Each hint costs a little XP — try without first.

A component receives props inside its parentheses, like ({ name, level }).

function PlayerCard({ name, level }) {
  return (
    <div className="card">
      <h3>{name}</h3>
      <p>Level {level}</p>
    </div>
  )
}

Mission submission is mock-only for now. The Code Lab uses deterministic checks before any AI help.
