fix: drop assistant prefill from structured output tutorial - #44
Merged
Conversation
Claude 4.6 removed support for assistant-message prefill — the conversation must end with a user message. Method B now demonstrates XML scaffolding alone, which remains a valid Anthropic-specific prompting technique and works across current models. README updated with a note linking to the 4.6 breaking-changes docs. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
