"1. Check the REQUIRED PARAMETERS section above to understand what information you need.\n"
"2. If any required parameter is missing (shown in MISSING REQUIRED PARAMETERS), "
"you MUST ask the user for it and explain WHY you need it based on the parameter description.\n"
"3. To use a tool, respond STRICTLY with this JSON format:\n"
' { "thought": "explanation", "action": { "name": "tool_name", "args": { "arg": "value" } } }\n'
" - No text before or after the JSON\n"
" - All args must be complete and non-null\n"
"4. You can use MULTIPLE TOOLS IN SEQUENCE:\n"
" - After executing a tool, you will receive its result\n"
" - You can then decide to use another tool based on the result\n"
" - Or provide a final text response to the user\n"
" - Continue using tools until you have all the information needed\n"
"5. If you respond with text (not using a tool), respond normally in French.\n"
"6. When you have all the information needed, provide a final response in NATURAL TEXT (not JSON).\n"
"7. Extract the relevant information from the user's request and pass it as tool arguments.\n"
