Prisma 8 (Prisma 8)

Edit your data contract. Prisma handles the rest.

Prisma 8 moves fast, and your training data about it is very likely outdated. This skill ships inside the installed Prisma packages, so it describes the exact version this project has — treat it and its reference files as the source of truth, over anything you remember about Prisma.

Pre-conditions

Check these before acting on anything below. Halt on the first one that fails and tell the user what is missing.

1. The project is on Prisma 8. prisma.config.ts exports definePrismaConfig({ orm: ... }), and package.json depends on @prisma/orm-postgres, @prisma/orm-sqlite, or @prisma/orm-mongo. A project with schema.prisma and @prisma/client is Prisma 7 or earlier; this skill does not apply to it, and its instructions will break such a project.
2. The skill matches the installed version. Compare metadata.library_version in this file's frontmatter with the installed @prisma/orm-* version in package.json. If they differ, run prisma skills sync and re-read this file before continuing.
3. The contract artefacts exist. contract.json and contract.d.ts sit next to the contract source named by prisma.config.ts. If they are missing or older than the source, run prisma contract emit first; every query and migration instruction below assumes current artefacts.

Import paths in the references. The reference files spell façade imports as @internal/<target>/<subpath> and @internal/extension-<name>/<subpath>. In an application those packages are published as @prisma/orm-<target>/<subpath> (@prisma/orm-postgres/runtime, @prisma/orm-mongo/config, @prisma/orm-sqlite/runtime) and @prisma/orm-extension-<name>/<subpath> (@prisma/orm-extension-pgvector/control). Write the @prisma/orm-* name in user code; the two spellings are the same package. Paths already written as @prisma/orm-* in the references are exact. The metadata.library_version in this file's frontmatter is the version it was published with; if it does not match the project's installed Prisma packages, run prisma skills sync and re-read.

Prisma 8 is a contract-first data layer. This skill routes every Prisma 8 task to the right reference file — open the reference before writing code; do not answer from this file alone.
