Production Readiness Review

Fill these in and the prompt below updates as you type. Anything you leave blank stays as a placeholder.

Review this code for production readiness:

{{code}}

Context: this is {{what_it_does}} in a {{application_type}}.

Check for:
- Security vulnerabilities (injection, XSS, auth bypass, data exposure)
- Error handling gaps (what happens when things fail?)
- Edge cases that could cause crashes or data corruption
- Performance issues at scale
- Logging and observability (can we debug this in production?)
- Code maintainability (will someone understand this in 6 months?)

Rate each issue as critical/warning/suggestion. Don't flag style preferences — only things that could cause real problems.
