One of 2 test cases the skill fixed. Same model, same prompt, with and without the skill.
In an old PHP file processing script, the code uses `$contents = @file_get_contents($filePath);` to prevent warnings if the file is missing, followed by checking if `$contents` is false. Refactor this code to remove error suppression and handle failure correctly.
| Checked | Without skill | With skill |
|---|---|---|
| The refactored code removes the @ error suppression operator. | Passed | Passed |
| The refactored code throws a RuntimeException when file_get_contents returns false. | Missed | Passed |

// ❌ Manual accumulation
$result = [];
foreach ($items as $item) {
if ($item->isActive()) {
$result[] = strtoupper($item->getName());
}
}
// ✅
$result = array_map(
fn($i) => strtoupper($i->getName()),
array_filter($items, fn($i) => $i->isActive())
);
// ❌ Manual key-value grouping
$grouped = [];
foreach ($items as $item) {
$grouped[$item->getCategory()][] = $item;
}
