# 18. Your assistant job and model decision

Use [the owner-assistant walkthrough](https://cowanworks.com/aicourse/learn/course-3/lesson-13). Ordinary chat can complete this practice without an ongoing agent.

**Job:** prepare a short owner brief from supplied calendar and messages. **Finished result:** fixed commitments, time-sensitive decisions and draft next steps, each tied to the supplied source. **Limits:** no sending, booking, purchasing or private individual records. **Mode:** start with a model that can accurately read and organize the supplied text; use deeper reasoning for conflicting constraints. Current external facts require verified source access.

```
Interview me about one responsibility I want help with. Ask one
question at a time until the result, sources, limits, timing and
success check are clear. Read the brief back before doing the job.
Do not connect accounts or create a recurring task during this setup.
```

Record product/workspace, model/mode if shown, included usage, separately billed connections and the person who manages payment. An API connection may incur charges outside a chat subscription. Inspect the actual account terms before enabling extra usage.
