def self.build(system_instruction:, tools:)
  tool_text = tools.empty? ? "None" : tools.map { |tool| tool_instruction(tool) }.join("\n")
  <<~PROMPT
    #{system_instruction}

    You may either answer the task directly or request exactly one tool.
    For a tool request, return one JSON object in a fenced json block:
    {"action":"tool_name","args":{"key":"value"}}
    Available tools:
    #{tool_text}
    Never request an unavailable tool. Do not return more than one action.
