Summary of the source lessons: Mix is both project scaffolding and operational interface. The lessons cover dependency management, task execution, and custom task authoring for repetitive workflows. A good Mix setup standardizes local and CI execution so team behavior remains predictable.
Use this as the orchestration layer around [[modules-and-docs]] and verification loops in [[testing]]. For larger codebases, pair these workflows with explicit contracts from [[typespecs-and-behaviours]].
