Quiz Me Skill — Development skill for Claude Code

That's it. That's the plugin.

Claude keeps the boring half — reading, searching, typing. You keep the half that can't be outsourced: **knowing why.** Nothing gets written until you convince it you do.

🎯 Pop quiz. And it's for you, not Claude.

Real bug. The support ticket says: *"the import claims 500 users imported, 0 failed — but only about 30 are actually in the database."*

Claude goes digging and surfaces this beauty:

async function importUsers(rows) {
  const failed = [];

  rows.forEach(async (row) => {
    try {
      await db.insertUser(row);
    } catch (err) {
      failed.push(row);
    }
  });

  return { imported: rows.length - failed.length, failed };
}

And then, instead of a diff, it hands you this:
