From the source SKILL.md

Activate this skill when an org is preparing to flip from Lightning Locker Service (the old per-namespace JavaScript sandbox built on SecureWindow/SecureElement proxies) to Lightning Web Security (LWS), the modern replacement based on JavaScript realms and standards-based browser primitives. LWS went GA for LWC in Spring '23, became the default for new orgs shortly after, and Salesforce has announced Locker for LWC will be retired — every org will eventually run on LWS.
