Example fix prompt
Generic prompt (your report adds the evidence)
Please fix this production issue in my app.
Issue PERF-003: Text compression is not enabled
Site: https://your-app.example
First confirm the issue in the code or live config. If it is not present, say so and change nothing.
Task: Enable Brotli or gzip compression for HTML, CSS, JavaScript and JSON responses at the server or CDN level (most hosts have a setting; for a custom Node server add compression middleware).
Constraints: make the smallest change that fixes this, keep the current design and behaviour, never paste secret values into code or chat, and tell me which files you changed.
Done when: Check the response headers for Content-Encoding: br or gzip.
