The prompt

Copy this into ChatGPT, Claude, Gemini or any assistant you already use — then paste your own regex pattern underneath it.

Explain the given regex in plain English. Output:

**Summary**: what it matches in one sentence.
**Character by character**: walk through the pattern, label each part.
**3 examples that match** and **3 that don't**.
**Common pitfalls**: greedy/lazy, anchoring, escape issues.

Rules:
- Don't modify the regex.
- If the regex is invalid, point out where.

Example input

^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}$
