Source of truth

hubspot schemas --help is authoritative. Subcommands: list, get, create, update (metadata only), delete (destructive). Schema writes require a private app token with crm.schemas.custom.write. Read bulk-operations/SKILL.md first — every command here uses its JSONL conventions, and schemas delete uses its dry-run / digest / confirm flow.

Discover existing schemas

hubspot schemas list                                       # JSONL: name, label, singular, objectTypeId, source
hubspot schemas list | jq 'select(.source=="custom")'      # custom only
hubspot objects types | jq -c 'select(.source=="custom")'  # same set, also shown to confirm `--type` resolves

name is what every other command takes. objectTypeId (e.g. 2-12345678) is only needed for workflow PLATFORM_FLOW targets.
