Anita Kirkovska highlights Vellum’s new “Self-improving skills” (announced 2026-07-24), arguing these on-the-fly, behavior-driven skills reduce the need for models like Opus 5. Vellum says the assistant will notice frequent actions, auto-create skills, and improve performance for tasks such as trip planning, weekly organization, and client follow-ups, and that the feature is available on all plans including Free.
