From the source SKILL.md

Help the creator migrate from another AI assistant into Vellum. Preserve as much of the source assistant as can be understood safely, but do not rely on deterministic adapters for OpenClaw, Hermes, Manus, or any other non-Vellum internals. These systems evolve quickly; inspect the actual source artifacts in front of you and map them into Vellum primitives.
