# Validated Designs
Design choices in Agenvoy that were later adopted or confirmed elsewhere, with their dates and commits. Tool, sub-agent, and resume designs are in [Tool & Task Designs](/docs/introduction-designs-tools).
Agenvoy has already implemented the design directions below, and other teams have since adopted similar approaches, confirming that these directions solve real problems agents face in practice. Every milestone links to a public commit or release, so you can check it yourself.
