Claude API Role Alternation Errors and Fixes

When interacting with Claude via the Messages API, messages must strictly alternate between user and assistant roles, always starting with a user message, or the API will return an error. Consolidate consecutive user artifacts inside a single user turn using nested XML tags.

<user_inputs> <artifact index="1" type="error_log">{{LOG}}</artifact> <artifact index="2" type="config">{{CONFIG}}</artifact> </user_inputs> Analyze both artifacts above in this single user turn and identify the configuration mismatch.
