What Prompt Engineering Coach does
As described by Serviceplan Group, the maker of this listing.
Description
Get expert feedback on your AI prompts. Paste an existing prompt, select the target model family (OpenAI, Anthropic, or Google), and receive a scored evaluation with specific improvements and an enhanced version.
Good Query Examples
- "Review this prompt and suggest improvements: [prompt text]" (model: anthropic)
- "Optimize this prompt for GPT-4: [prompt text]" (model: openai)
Bad Query Examples
- "Write me a prompt from scratch" → This agent coaches on existing prompts, it doesn't generate new ones.
- "Run this prompt and show me the results" → This agent evaluates prompts, it doesn't execute them. Use the AI model directly.
Limitations
- Requires an existing prompt to evaluate
- Cannot test or execute prompts
- Model-specific advice limited to OpenAI, Anthropic, and Google families

- prompt (required): The prompt text to evaluate
