{"description": "A special tool to indicate you have completed all tasks and are about to enter idle state.\n\nUnless user
explicitly requests to stop, this tool can only be used when all three conditions are met:\n1. All tasks are perfectly
completed, tested, and verified\n2. All results and deliverables have been sent to user via message tools\n3. No further
actions are needed, ready to enter idle state until user provides new instructions\n\nYou must use this tool as your final
action.", "name": "idle", "parameters": {"type": "object"}}
{"description": "Send a message to user.\n\nRecommended scenarios:\n- Immediately acknowledge receipt of any user message\n-
When achieving milestone progress or significant changes in task planning\n- Before executing complex tasks, inform user of
expected duration\n- When changing methods or strategies, explain reasons to user\n- When attachments need to be shown to
user\n- When all tasks are completed\n\nBest practices:\n- Use this tool for user communication instead of direct text
output\n- Files in attachments must use absolute paths within the sandbox\n- Messages must be informative (no need for user
response), avoid questions\n- Must provide all relevant files as attachments since user may not have direct access to local
filesystem\n- When reporting task completion, include important deliverables or URLs as attachments\n- Before entering idle
state, confirm task completion results are communicated using this tool", "name": "message_notify_user", "parameters":
{"properties": {"attachments": {"anyOf": [{"type": "string"}, {"items": {"type": "string"}, "type": "array"}], "description":
"(Optional) List of attachments to show to user, must include all files mentioned in message text.\nCan be absolute path of
single file or URL, e.g., \"/home/example/report.pdf\" or \"http://example.com/webpage\".\nCan also be list of multiple
absolute file paths or URLs, e.g., [\"/home/example/part_1.md\", \"/home/example/part_2.md\"].\nWhen providing multiple
attachments, the most important one must be placed first, with the rest arranged in the recommended reading order for the
user."}, "text": {"description": "Message text to display to user. e.g. \"I will help you search for news and comments about
hydrogen fuel cell vehicles. This may take a few minutes.\"", "type": "string"}}, "required": ["text"], "type": "object"}}
{"description": "Ask user a question and wait for response.\n\nRecommended scenarios:\n- When user presents complex
requirements, clarify your understanding and request confirmation to ensure accuracy\n- When user confirmation is needed for
an operation\n- When user input is required at critical decision points\n- When suggesting temporary browser takeover to
user\n\nBest practices:\n- Use this tool to request user responses instead of direct text output\n- Request user responses
only when necessary to minimize user disruption and avoid blocking progress\n- Questions must be clear and unambiguous; if
options exist, clearly list all available choices\n- Must provide all relevant files as attachments since user may not have
direct access to local filesystem\n- When necessary, suggest user to temporarily take over browser for sensitive operations
or operations with side effects (e.g., account login, payment completion)\n- When suggesting takeover, also indicate that the
user can choose to provide necessary information via messages", "name": "message_ask_user", "parameters": {"properties":
