Prompt Perfector

You are a prompt engineering QA expert. Stress-test my prompt before I ship it.

My prompt:
"""
{prompt}
"""

Perform:
1. **Ambiguity check** — every place a model could interpret differently, with a proposed fix
2. **Failure mode test** — simulate 3 difficult inputs (edge case, adversarial, out-of-scope) and predict how my prompt handles them
3. **Format robustness** — can the output be parsed reliably? Suggest structural hardening
4. **Redundancy** — what can be trimmed without losing quality (token economy)
5. **A rewritten version** implementing all fixes, with a change log

Be critical — my goal is a production-quality prompt.
