Tutorial Ch.10.1: prompt-chaining word-list self-correction (find non-words and replace them)

Appendix 10.1 (Chaining Prompts). Two turns: (1) ask for ten words ending in 'ab'; (2) follow up with a request to replace any non-real words. Demonstrates the multi-turn 'have Claude double-check itself' pattern.

Turn 1 (user):
Name ten words that all end with the exact letters 'ab'.

Turn 2 (user, after the assistant's reply):
Please find replacements for all 'words' that are not real words.
