---

- **changed** — The engine peer moves to @prisma/cli-engine@0.3.0 with @prisma/management-api-sdk as a peer dependency instead of a regular dependency
- **added** — The prisma-8 skill now teaches agents the migration system's real model with plan-from-state and explicit baselines
- **fixed** — migration plan now refuses to plan from an empty database when the project already has migrations on disk, providing a structured error instead of silently producing a full-create package
- **fixed** — Structured errors' docsUrl links now point at docs.prisma.io/docs/orm/v8/ instead of orm/next/ paths
- **fixed** — The language server now canonicalizes Windows file URIs so schema files configured with Windows paths are recognized as part of the project
- **fixed** — The dev dist-tag no longer goes stale after a release by publishing a -dev.1 build of the new base

#### v8.0.0-rc.8

The toolchain releases against `@prisma/cli-engine@0.3.0`, which now takes the Management API SDK as a peer dependency, and `migration plan` no longer plans silently from an empty database when migrations already exist.

The upgrade recipe for this hop: the [user recipe](https://github.com/prisma/prisma/tree/v8.0.0-rc.8/skills/prisma-8/upgrading/app/upgrades/8.0.0-rc.7-to-8.0.0-rc.8/).

##### Breaking changes

- **The engine peer moves to `@prisma/cli-engine@0.3.0`** — `@prisma/orm-toolchain` declares the unified CLI's engine as an exact peer, and this release peers 0.3.0 (up from 0.2.3). The engine's change: `@prisma/management-api-sdk` moves from a regular dependency to a peer dependency (`^1.55.0`), supplied by the `prisma` CLI shell at runtime. Installs assembled by the unified `prisma` CLI resolve one engine as before; a host that pins the engine itself must move to 0.3.0 and, if it runs the engine outside the CLI shell, install the SDK itself. ([prisma/prisma-cli#236](https://github.com/prisma/prisma-cli/pull/236))

##### Features

- The `prisma-8` skill, auto-installed into every project by `prisma init`, now teaches agents the migration system's real model — plan-from-state with explicit baselines, not a linear chain — so agents stop producing full-create plans against real databases. ([#30123](https://github.com/prisma/prisma/pull/30123))

##### Fixes

- `migration plan` refuses to plan from an empty database when the project already has migrations on disk, instead of silently producing a full-create package that fails against any real database. A structured error explains the situation; planning from baseline remains available as an explicit opt-in. ([#30122](https://github.com/prisma/prisma/pull/30122))
- Structured errors' `docsUrl` links now point at `docs.prisma.io/docs/orm/v8/...` instead of the pre-RC `orm/next/...` path. ([#30126](https://github.com/prisma/prisma/pull/30126))
- The language server now canonicalizes Windows file URIs, so schema files configured with Windows paths (`D:\project\next.prisma`) are recognized as part of the project. ([#30121](https://github.com/prisma/prisma/pull/30121))
- The `dev` dist-tag no longer goes stale after a release: a release push to `main` also publishes a `-dev.1` build of the new base, so `@dev` installs always resolve against the current release's engine pins. ([#30125](https://github.com/prisma/prisma/pull/30125))
