+# Design card: Parent letter assistant
+
+**For the AI Agents workshop · filled-in example for guide 3**  
+LeX Consultancy B.V. · 20 September 2026
+
+This is what the card looks like once filled in. Form: **Agent with knowledge base**, guide 3. Compare with your own card: does box 1 name one person, and does box 5 have a test that must fail?
+
+| 1. Who is it for | 2. What goes in |
+| --- | --- |
+| A form tutor who at 16:00 still has to send a letter about next week's school trip and has three woolly paragraphs. Wants the letter to sound like the school, not like themselves. | The draft letter or loose sentences, pasted into the chat. If the class or the requested action is missing, the agent asks for it. |
+
+| 3. What comes out | 4. What it must stick to |
+| --- | --- |
+| The rewritten letter with a subject line, in the style of the style guide (B1, formal address, structure), and below it "What I changed": at most five points with the rule for each. Missing facts as [FILL IN]. | The style guide of Example College (style-guide-example-college.pdf) in the knowledge base; invent no dates, names or appointments; no introduction or compliment from the agent itself. |
+
+**5. How you know it works**
+
+| Test | What goes in | What must come out |
+| --- | --- | --- |
+| 1 | A woolly letter about a parents' evening | A short letter with date, time, place and what the parent must do; five improvement points |
+| 2 | Two loose sentences without a class | The agent first asks which class the letter is for |
+| 3 (the hard one) | A letter without the date of the trip | [FILL IN] where the date should be, no invented date |
+
+**What this card decided**
+
+- Boxes 1 and 2 decided the input fields and the first question of the app.
+- Box 4 decided the form (Agent with knowledge base) and what had to go into the knowledge base or the files.
+- Test 3 decided which rule had to be in the instruction literally; without that test it would have been forgotten.
