- AI reviews miss things: treat this as a second pair of eyes, not a sign-off.
- Ask it to write a test that shows each bug before you fix it.
An example, filled in
Review this JavaScript code as a careful senior developer would. What it does, and where it runs: a form on our website that saves sign-ups to a database. What matters most here: security. List the problems in order of seriousness, each with where it is, why it’s a problem and a suggested fix as a short code snippet. Look especially for bugs, security problems (such as injection or exposed secrets), missing error handling and unclear names. Tell me what’s good, too, and keep the tone constructive. If you’re unsure whether something is a bug, say so and explain what would confirm it. The code: app.post('/signup', async (req, res) => { const email = req.body.email; await db.query("INSERT INTO signups (email) VALUES ('" + email + "')"); res.send('Thanks!'); });
