prisma v8.0.0-rc.6

PostgreSQL temporal columns move from Date to explicit Temporal-or-text representations, the prisma-8 agent skill ships inside the ORM packages a project installs, prisma orm init hands agent-skills setup to the family-level prisma init, and the toolchain releases against @prisma/cli-engine@0.2.2 — the engine that evaluates prisma.config.ts correctly under pnpm symlink layouts.

The upgrade recipe for this hop: the user recipe.

Breaking changes

• PostgreSQL temporal columns read as Temporal values or text, never Date — each of date, timestamp(p), timestamptz(p) and time(p) now has two representation-explicit codecs: a Temporal-backed one (the bare PSL spellings Date, Timestamp, Timestamptz, Time select it) and a text one (DateString, TimestampString, TimestamptzString, TimeString). The previous codecs (pg/date@1, pg/timestamp@1, pg/timestamptz@1, pg/time@1, sql/timestamp@1 / field.timestamp()) are removed with no aliases. Pick a representation per column, re-emit every contract, and provide a global Temporal implementation (e.g. import 'temporal-polyfill/full/global') wherever a Temporal-backed column is read. See the migration recipe. (#30073)

  Before:

  occurredAt Timestamptz  // read as Date
  

  After (read as Temporal.Instant):

  occurredAt Timestamptz
  

  Or, to keep PostgreSQL's text unchanged:

  occurredAt TimestamptzString
  

• prisma orm init no longer installs agent skills — the GitHub fetch (npx skills add) is removed and nothing replaces it inside orm init: agent-skills setup belongs to the family-level prisma init command, which init's next-steps now point to. The --skip-skills flag is removed with the behavior it opted out of, and the skill-install failure exit (code 6) is retired. Scaffolding is otherwise unchanged. (#30097)

• The engine peer moves to @prisma/cli-engine@0.2.2 — @prisma/orm-toolchain declares the unified CLI's engine as an exact peer, and this release peers 0.2.2 (up from 0.2.0). Installs assembled by the unified prisma CLI resolve one engine as before; a host that pins the engine itself must move to 0.2.2. The new engine evaluates prisma.config.ts through pnpm symlink layouts that are not realpath'd (prisma/prisma-cli#222) and exports its CI detector (prisma/prisma-cli#224).

Features

• The prisma-8 skill travels in the npm tarballs — skills/prisma-8/ ships inside @prisma/orm-postgres, @prisma/orm-sqlite, and @prisma/orm-mongo, stamped with the package name and version so prisma skills sync can copy it into agent harness directories and detect staleness from the installed packages rather than fetching from GitHub. The two upgrade skills fold into the prisma-8 router as its "upgrading" branch. (#30096)
