Overview

Test adapter that returns schema-conformant placeholder values without calling any LLM API. Useful for testing flows that include LLM steps.

For clarify/detour steps with a schema, returns a hash of default values matching each field’s declared type. For describe/summarize steps, returns a placeholder string.

Examples:

adapter = Inquirex::LLM::NullAdapter.new
result = adapter.call(clarify_node, answers)
# => { industry: "", employee_count: 0, ... }
