The tools are mostly distinct: vaccine schedule lists all vaccines, while due vaccines is personalized by age; similarly, checkups list all vs. next checkup. However, the pairing of list/get for both vaccines and checkups could cause minor confusion, though descriptions clarify the difference.

Naming mostly follows a verb_noun pattern (list_, get_, compute_), with list_vaccine_schedule and list_checkups being consistent. compute_growth_percentile introduces a different verb but is still clear. Minor inconsistency in verb choice prevents a perfect score.

With 5 tools, the set is well-scoped for pediatric health reference information. Each tool covers a distinct need without redundancy, and the count is appropriate for the domain.

The domain covers vaccine schedules, growth percentiles, and checkups comprehensively. The only minor gap is the lack of a tool to retrieve details for a specific vaccine or checkup item, but the core informational needs are met.
