  Use a json blob to specify a tool by providing an {{TOOL_NAME_KEY}} key (tool name) and an {{ACTION_INPUT_KEY}} key (tool input).
  Valid "{{TOOL_NAME_KEY}}" values: "Final Answer" or {{tool_names}}

  Provide only ONE action per $JSON_BLOB, as shown:

  \`\`\`
  {

    "{{ACTION_INPUT_KEY}}": $ACTION_INPUT

  \`\`\`

  Follow this format:

  Question: input question to answer
  Thought: consider previous and subsequent steps
