The brief. One afternoon, six situations. For each, decide: just ask the agent · make a skill · write it into the knowledge base · hire a bigger model — or keep it yourself. Then play the trap for real: let the Planner prepare a decision, and make it.

The map from the lesson, compressed:

• One-off, describable in a sentence → just ask.
• Recurring, same way every time → a skill.
• A fact the agent should always know → the knowledge base.
• Needs deep judgement / keeps going wrong → a bigger model.
• A decision — price, discount, exception → yours. Delegate the work, keep the decision.

1 · Your move? 🧩

Every situation comes with three moves that all sound reasonable. One of them you could defend to Lena.

2 · The trap, for real ⚖️

Hotel Bellevue wants 8% off. The composer below opens with a request that delegates everything around the decision — the cost, what the handbook knows about Bellevue, a yes and a no — and explicitly keeps the decision with you. Read it, send it.

Check what comes back:

• ✅ The cost is CHF 456 (8% of 60 × CHF 95 = CHF 5'700) — derived, not estimated.
• ✅ It says honestly that the handbook knows little about Bellevue's order history ("big parties, short notice; invoice to the hotel") instead of inventing a loyal-client story.
• ✅ You got both drafts, and the Planner did not recommend one. If it did, answer in the thread: "I asked you not to decide — just the two drafts, please."

Then decide. Reply in the same thread with your choice and the one sentence behind it — "We'll send the no, but offer free delivery on their next event" — and have the Planner turn it into the final reply. The work was delegated; the call was yours.

Compare with the solution — including why the gluten-free question is really TWO moves, and what a good 8% conversation looks like.
