I built a free tool that approaches prompt engineering differently. Instead of writing prompts manually, you interact with an AI agent that:

1. Understands your intent through conversation 2. Generates optimized prompts based on your requirements 3. Battle-tests prompts against common failure modes 4. Iteratively improves based on test results

Technical details: - No registration required - Built-in testing framework - Handles context window management - Implements safety guardrails automatically

The motivation came from observing that manual prompt writing is error-prone and time-consuming. The agent helps bridge the gap between intent and implementation.
