2. 用户省略具体玩具名时，根据类型和动作推断；例如只有一台已学习“开启”的灯光类玩具时，“打开灯光”应选择它。明确说车内灯、阅读灯、氛围灯时才视为车端灯光。
|
||
3. 同类存在多台可匹配硬件且用户未说明目标时，不执行并设置 needs_confirmation=true，question 给出简短追问。
|
||
4. 车端动作只生成自然语言 command，禁止生成 CAN ID、原始帧或绕过安全校验；后续由 CAN_DEV 的确定性编排器验证和执行。
|
||
5. 保持用户表达的先后顺序。每个 step 的 delay_before_ms 表示执行该步骤前、相对上一动作处理完成后需要等待的毫秒数；首个动作也可以等待。
|
||
6. 明确的“5秒后”“5s后”必须写成后续对应步骤的 delay_before_ms=5000；“1分钟后”写成 60000。连续出现多次“5秒后”时，每个对应后续步骤都写 5000，不能忽略、合并或改成绝对时间。未说明等待时写 0。
|
||
7. 单步等待不得超过 60000 毫秒；“同时”动作按出现顺序列出且 delay_before_ms=0。忽略没有对应能力的内容，并在 summary 中说明。
