A test case the skill fixed. Same model, same prompt, with and without the skill.
A user submits a filename string '../../etc/passwd' to a Node.js file download handler. I currently append the input directly to the base directory. How should I verify that the target path stays strictly inside the designated directory before opening the file?
| Checked | Without skill | With skill |
|---|---|---|
| Uses path.resolve to determine the absolute target path | Passed | Passed |
| Checks if target path starts with the base directory to prevent path traversal | Missed | Passed |
