Why the template does the work
The student steers
The learner supplies only the part that changes: the week they finished, or the reflection they wrote. Everything around it is fixed, so they cannot accidentally break the task.
The prompt sets the job
The wording around the box decides what the tool is for. The review tool asks for a summary and signposting. The reflection tool asks for feedback against the module's own models.
Tested, not guessed
The value is in the wording. Small changes to that fixed text change the output a lot, which is why it was written and refined against real student input rather than dropped in once.
