Defined in:
lib/pikuri/agent.rb

Overview

A blank turn was requested against a conversation holding nothing but the assembled system prompt, on a provider that would render that as messages: [] (see SEPARATE_SYSTEM_FIELD_PROVIDERS):

agent.run_loop(user_message: nil)   # fresh chat, backend Anthropic
# => EmptyTurnError; the host catches it and prompts for a real message

Narrow by construction: every injected block lands as role: :user (#append_reference_block), so a skill-only or memory-only bare load has a message to complete against and never reaches here. What remains is a genuinely empty conversation.

Content-neutral: #provider is all it carries — the host owns any user-facing wording.
