Design card: Transcription tool
For the AI Agents workshop · filled-in example for guide 5
LeX Consultancy B.V. · 20 September 2026
This is what the card looks like once filled in. Form: Workflow with tool, guide 5. 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 |
|---|---|
| The minute-taker of a department meeting whose minutes are always two weeks late. Has a 45-minute mp3 and fifteen minutes of time. | One audio file (mp3, m4a or wav, at most 5 MB) through a file field. For the prototype only a fictional recording read out by a computer voice. |
| 3. What comes out | 4. What it must stick to |
|---|---|
| Minutes with five headings (Meeting, Summary, Decisions, Action points with owner and date, Deferred) and below them the full transcript. Uncertain names with a question mark. | No real recordings in Dify cloud (privacy frame); delete audio after transcription; someone reads the minutes. Tool: Speech To Text with your own OpenAI key. |
5. How you know it works
| Test | What goes in | What must come out |
|---|---|---|
| 1 | The fictional three-minute recording | Minutes with five headings, three action points with an owner |
| 2 | The same recording at 128 kbps (too big) | An error about the file size; shrink to 32 kbps |
| 3 (the hard one) | A photo instead of audio | The input field refuses the file; only Audio is enabled |
What this card decided
- Boxes 1 and 2 decided the input fields and the first question of the app.
- Box 4 decided the form (Workflow with tool) 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.
