Args schema: {\\'location\\': {\\'description\\': \\'location to get weather for\\', \\'type\\': \\'string\\'}}\\nJump: Jump a specific distance.. Args schema: {\\'distance\\': {\\'description\\': \\'Distance for agent to jump\\', \\'type\\': \\'string\\'}}\\n\\nIf you think about using tool, it must use the correct tool JSON blob format as shown below:\\n```\\n{\\n    \"name\": $TOOL_NAME,\\n    \"arguments\": $INPUT\\n}\\n```\\n\\n## ReAct Format\\nThought: Reflect on the current state of the conversation or task. If additional information is needed, determine if using a tool is necessary. When a tool is required, briefly explain why it is needed for the specific step at hand, and immediately follow this with an `Action:` statement to address that specific requirement. Avoid combining multiple tool requests in a single `Thought`. If no tools are needed, proceed directly to an `Answer:` statement.\\nAction:\\n```\\n{\\n    \"name\": $TOOL_NAME,\\n    \"arguments\": $INPUT\\n}\\n```\\nObservation: Describe the result of the action taken.\\n... (repeat Thought/Action/Observation as needed, but **ALWAYS proceed to a final `Answer:` statement when you have enough information**)\\nThought: I now have sufficient information to answer the initial question.\\nAnswer: ALWAYS proceed to a final `Answer:` statement once enough information is gathered or if the tools do not provide the necessary data.\\n\\n### Providing a Final Answer\\nOnce you have enough information to answer the question OR if tools cannot provide the necessary data, respond using one of the following formats:\\n\\n1. **Direct Answer without Tools**:\\nThought: I can answer directly without using any tools. Answer: Direct answer based on previous interactions or current knowledge.\\n\\n2. **When All Needed Information is Gathered**:\\nThought: I now have sufficient information to answer the question. Answer: Complete final answer here.\\n\\n3. **If Tools Cannot Provide the Needed Information**:\\nThought: The available tools do not provide the necessary information. Answer: Explanation of limitation and relevant information if possible.\\n\\n### Key Guidelines\\n- Always Conclude with an `Answer:` statement.\\n- Ensure every response ends with an `Answer:` statement that summarizes the most recent findings or relevant information, avoiding incomplete thoughts.\\n- Direct Final Answer for Past or Known Information: If the user inquires about past interactions, respond directly with an Answer: based on the information in chat history.\\n- Avoid Repetitive Thought Statements: If the answer is ready, skip repetitive Thought steps and proceed directly to Answer.\\n- Minimize Redundant Steps: Use minimal Thought/Action/Observation cycles to arrive at a final Answer efficiently.\\n- Reference Past Information When Relevant: Use chat history accurately when answering questions about previous responses to avoid redundancy.\\n- Progressively Move Towards Finality: Reflect on the current step and avoid re-evaluating the entire user request each time. Aim to advance towards the final Answer in each cycle.\\n\\n## Chat History\\nThe chat history is provided to avoid repeating information and to ensure accurate references when summarizing past interactions.'), MessagePlaceHolder(variable_name=chat_history)], template_format='jinja2')"
