Overview

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

For extract steps with a schema, returns a hash of default values matching each field's declared type. Fields constrained to a list of allowed values (enum/multi_enum resolved from questions) return the first allowed value, so placeholders stay valid answers for the downstream question. Without a schema, returns a placeholder string.

Examples:

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

def call(node, _answers = {})
  if node.schema
    node.schema.fields.each_with_object({}) do |(name, type), acc|
      acc[name] = placeholder_for(node.schema, name, type)
    end
  else
    "(placeholder #{node.verb} output for #{node.id})"
  end
end

#summarize(node, transcript, _answers = {}) ⇒ String

Placeholder summary, in the markdown shape a real summary takes — so a renderer wired against this adapter exercises its heading, list, and paragraph handling rather than one unbroken line.

Parameters:

  • node (LLM::Node) —

    the summarize step

  • transcript (String) —

    the session transcript

  • _answers (Hash) (defaults to: {}) —

    ignored

Returns:

  • (String) —

def summarize(node, transcript, _answers = {})
  <<~MARKDOWN.strip
    This is a placeholder summary for #{node.id}. No language model was called.

    ## What the session contained

    - A transcript of #{transcript.to_s.strip.length} characters.
    - Nothing else worth reporting, because this adapter invents nothing.
