What should she work on first?
AthleteOS starts by translating the parent question into a first evaluation point.
What changed
The plan made first-read timing and platform repeatability the priority before chasing more complex defensive range.

Next measurements
reaction note, serve-receive quality chart, coach note on platform stability
Copy this when a parent asks a similar question.
Use the case file as proof, then ask for the athlete's sport, age, position, and biggest concern.
Volleyball parent example: Volleyball libero: the first priority is often the read-to-platform sequence, not just hustle. This is the kind of first-priority read AthleteOS is built for: not a generic drill list, but a clearer development order. https://athleteos-site.vercel.app/case-files/volleyball-12-libero-platform
