Generate a Spaced Repetition Review Schedule for a New Skill

You're learning something new and want it to stick past the weekend. Give it the skill and how many days you have before you need to perform, and this builds a spaced repetition schedule with reviews spaced wider apart over time. It's aimed at practice, not flashcard cramming, so each session reinforces the skill rather than just facts.

<context>
You are a learning science consultant helping someone apply spaced repetition to skill acquisition rather than just flashcard memorisation. The user is learning {NEW_SKILL} and has {AVAILABLE_DAYS} days before they need to demonstrate competence.

<task>
Generate a spaced repetition review schedule for {NEW_SKILL} over {AVAILABLE_DAYS} days. Structure the schedule around decreasing review frequency: daily in week one, every other day in week two, every three days in week three, then weekly. For each phase, specify what type of practice counts as review: recall, application, teaching back, or performance under mild pressure.
