# Feishu Task Tools

Tools:
- `feishu_task_create`
- `feishu_task_subtask_create`
- `feishu_task_get`
- `feishu_task_update`
- `feishu_task_delete`
- `feishu_task_comment_create`
- `feishu_task_comment_list`
- `feishu_task_comment_get`
- `feishu_task_comment_update`
- `feishu_task_comment_delete`
- `feishu_task_attachment_upload`
- `feishu_task_attachment_list`
- `feishu_task_attachment_get`
- `feishu_task_attachment_delete`
- `feishu_task_add_tasklist`
- `feishu_task_remove_tasklist`
- `feishu_tasklist_create`
- `feishu_tasklist_get`
- `feishu_tasklist_list`
- `feishu_tasklist_update`
- `feishu_tasklist_delete`
- `feishu_tasklist_add_members`
- `feishu_tasklist_remove_members`

## Notes

- `task_guid` can be taken from a task URL (guid query param) or from `feishu_task_get` output.
- `comment_id` can be obtained from `feishu_task_comment_list` output.
- `attachment_guid` can be obtained from `feishu_task_attachment_list` output.
- `user_id_type` controls returned/accepted user identity type (`open_id`, `user_id`, `union_id`).
- If no assignee is specified, set the assignee to the requesting user. Avoid creating unassigned tasks because the user may not be able to view them.
- Task visibility: users can only view tasks when they are included as assignee.
- Current limitation: the bot can only create subtasks for tasks created by itself.
- Attachment upload supports local `file_path` and remote `file_url`. Remote URLs are fetched with runtime media safety checks and size limit (`mediaMaxMb`).
- Keep tasklist owner as the bot. Add users as members to avoid losing bot access.
- Use tasklist tools for tasklist membership changes; do not use `feishu_task_update` to move tasks between tasklists.
