# Introduction Following https://github.com/twentyhq/twenty/pull/17632 and https://github.com/twentyhq/twenty/pull/17572 This PR deprecates the agent, skill, field metadata and role `standardId` in favor of the `universalIdentifier` usage ## Note - Removed previous standard ids declaration modules - Twenty-sdk now re-exports the `STANDARD_OBJECTS` universalIdentifier hashmap constant - deleted some sync-metadata deadcode too ( mainly types )
