Can I use this for models other than Claude?

Yes, while it includes Claude-specific techniques like XML tags, it also optimizes prompts for general LLM performance across GPT and Gemini models.

What triggers the prompt improvement workflow?

You can activate the skill by asking Claude to 'improve this prompt', 'refine prompt', or 'optimize prompt' during your development session.

How does the Improve Prompt skill work?

It evaluates your existing prompt against quality gates like clarity and structure, then rewrites it using best practices such as XML tags, few-shot examples, and explicit constraints.

Does it handle complex output formats?

Absolutely. One of the primary functions is to specify and structure the expected output format to ensure consistent results in production environments.
