Nordlicht Reisen GmbH wants to turn a request for a group trip into a checked draft quote that a trip planner approves (M-01, M-02). A single prompt agent would have all the tools, all the rights and one instruction that would have to know accommodations, ferries, prices and travel terms at the same time. This lesson decomposes the goal into steps, agents with a clear role, tools with a level and the places where a person decides. The result is the design on which all further lessons build.
Prior knowledge. "AI track, lesson T7.1" separates agent, workflow and function; "T7.3" and "T7.4" show approvals and workflows with fixed steps; "T7.6" shows the five patterns and calculates that cost, errors and waiting time grow with every agent. "T6.4" puts hard rules into code, "T1.4" names Microsoft's principles of responsible AI and the notices under the AI Act. "AI-103, lesson 1.5" introduces oversight modes for tools. Here begins what the exam demands beyond that: designing a whole goal, not building an example.
New in this lesson. The case gets fixed responsibilities and tool names. The MCP tools are called buchungen/buchung_lesen (from AI-103), lieferanten/verfuegbarkeit_lesen, lieferanten/vorreservieren and rechner/preis_berechnen (made up). Saving a draft is not an MCP tool but a function of the application, app/entwurf_speichern; M-04 thus keeps three MCP servers. recht reads knowledge from the index (M-06) and has no tools. The flow and the levels are in the tables below; the revision between texter and pruefer happens at most once (this is how lesson 0.2 calculates).
The requirement
All numbers are assumptions of the task.
| No. | Requirement | Type | Measure | Weight | Source |
|---|---|---|---|---|---|
| 1.1-01 | Every step from the request to the draft has exactly one responsible party: an agent, the code or a person. | F | 0 steps without a responsible party | Must | M-02 |
| 1.1-02 | No agent has level A3; changing calls (A2) go only with a person's approval. | R | 0 agents with A3 | Must | M-05 |
| 1.1-03 | No agent has a tool above its level. | R | 0 violations in the check code | Must | M-05 |
| 1.1-04 | Legal questions leave the team to a person. | R | 100 % of legal questions | Must | M-03 |
| 1.1-05 | For every statement in the draft the planner sees the source and can correct it. | Q | 100 % of the numbers with a source | Should | HAX |
| 1.1-06 | The control loop between texter and pruefer is limited. |
R | at most 1 revision | Must | Costs |
