用 CodeBuddy CLI 派发独立任务时如何做交叉验证

需要将工作非交互派发给 WorkBuddy / CodeBuddy CLI，或把它当作独立第二实现做交叉验证时使用。适合批量或并行独立子任务，以及从不同模型家族获取设计或评分算法的第二意见。不要用于需要当前对话上下文或敏感材料。

适用场景

解决思路

1. **Independent cross-validation** — get a second, independent implementation of a
2. Batch/parallel independent subtasks.
3. Second opinion on a design or scoring algorithm from a **different model family**
4. **One non-trivial task per dispatch.** Many tiny dispatches waste the overhead N times.
5. Parallel dispatch means each job pays the overhead separately — worth it only for
6. `total_cost_usd` reports **0** — it is not per-call billed. It burns the **user's
7. **`env: node: No such file or directory`** → invoke via the bundled node, not the
8. **Silent no-op because tools were denied** → the agent reports it in prose and exits
