The defect

prisma@8.0.0-rc.3 shipped depending on @prisma/composer@0.6.0-dev.16 and @prisma/orm-toolchain@8.0.0-rc.1-dev.40 — dev builds, in a release. Two reasons, and neither was a decision:

  1. Nothing checked. Conformance verified import purity, validators, and tarball installs. Nothing looked at whether a shipped dependency was a dev build, so interim pins from earlier slices sat in the manifest until a release publish carried them to the registry.
  2. The automation that would have moved them has never run. auto-repin.yml followed each product's release dist-tag, so it would have moved these pins onto real releases — but it needed a token that was never provisioned, so it never executed once.

The rule, and how it is kept

Operator ruling (2026-08-17): a non-dev CLI depends on the latest non-dev composer and ORM; a dev CLI depends on their latest dev builds.

  • The committed manifests hold the released versions, kept current by update-product-versions.yml. main therefore stays releasable, and every version change arrives as a pull request CI has tested. A release publish uses those pins exactly as committed, so a release is reproducible from its tag.
  • A dev publish rewrites them to each product's dev dist-tag in CI, ephemerally — the same treatment the CLI's own version already gets. Build and conformance run after the rewrite, in the same run, so a broken product dev build fails the dev publish instead of shipping inside it.
  • Check 4 of the conformance suite refuses a release whose dependencies include a -dev. version. It takes the channel from determine-version.ts, and it has no exception mechanism on purpose: a suppressed finding exits 0, which is exactly how rc.3 shipped.

One script serves both channels (--channel release|dev), so the two cannot drift apart. It now edits packages/prisma/package.json as well as packages/cli/package.json — the old one ignored the unscoped package, whose dependency list must match.

The shell moves to @prisma/composer-cli

@prisma/composer dropped its ./family export when composer split its CLI out, so the old pin only worked because it was a dev build from before the split. The shell and packages/prisma now depend on @prisma/composer-cli@0.6.0-dev.22, which declares @prisma/cli-engine as an exact peer at 0.1.1 — the version this repo ships. That removes one of the two engine copies an install resolved, and composer's recorded pin exception is deleted.

The engine-pin check now reads a family's peerDependencies as well as its dependencies. Without that it would have silently stopped measuring composer the moment composer did the right thing.

@prisma/composer stays as a devDependency: the startup probe imports it to prove the eager-loading detector works, and pnpm's strict layout will not resolve an undeclared package.

Consequence: releases are blocked, correctly

Neither product has published a non-dev version this CLI can use, so check 4 fails the release channel today. That is the check working. What each product needs to publish:

  • @prisma/composer-cli@0.6.0 — its only non-dev version — cannot be installed at all. It was published with npm publish instead of pnpm publish, so its dependency on @prisma/composer is the literal string workspace:0.6.0; npm install @prisma/composer-cli@0.6.0 fails with EUNSUPPORTEDPROTOCOL. Composer needs to publish with pnpm publish from a commit that peers the engine at the shipped version (0.6.0-dev.22 already does). Composer's repo has no check that installs its own tarball, which is how this reached the registry; check 3 here catches exactly that class and is worth porting.
  • @prisma/orm-toolchain@8.0.0-rc.1 has no engine relationship, and its ./cli export contains no ormCommandFamily — only createContractEmitCommand, createFormatCommand, loadContractFromTs. The engine-based family exists only in dev builds, and the newest of those went back to declaring the engine at 0.0.9. prisma/prisma needs to adapt to the current engine and publish that as a release.

The ORM's engine-pin exception is the last one left; it dies with that publish, after which the check can move from pin equality to peer satisfaction. Recorded in deferred.md.

Also here

  • DEPLOY_GITHUB_TOKEN replaces REPIN_PAT, and the workflow is renamed from auto-repin to update-product-versions. docs/oss/release-automation.md is new: what the token is for, why it belongs to a service account, the exact permissions, the notification step each product repo needs, and a table of failure modes. The token is provisioned in all three repositories.
  • The workflow closes any earlier open version-update pull request before opening a new one. Two of them race each other's auto-merge and one lands on a stale lockfile.
  • minimumReleaseAgeExclude entries become per-package. They named exact interim versions, so every version change needed an edit here too.
  • turbo.json declares PUBLISH_CHANNEL for the conformance task. turbo passes only declared variables through, so undeclared it would have read release in every run — found by running it.

Verification

  • pnpm lint, pnpm typecheck, pnpm test (979 tests), pnpm test:scripts (63) all pass.
  • PUBLISH_CHANNEL=dev pnpm check:conformance: 0 failing, 2 allowed — the ORM's engine mismatch, on the record.
  • PUBLISH_CHANNEL=release pnpm check:conformance: 4 failing, one per dev dependency per published package. This is what would have stopped rc.3.
  • The @prisma/composer-cli@0.6.0 install failure was reproduced in a clean sandbox, not inferred from its manifest.

Summary by CodeRabbit

  • New Features

    • Added automated synchronization of product package versions for development and release channels.
    • Added scheduled and on-demand version reconciliation with pull request creation and automatic merging.
    • Development publishes now automatically propagate compatible product versions.
  • Bug Fixes

    • Release validation now detects and reports development-only dependencies in release packages.
    • Improved dependency pin checks, including peer dependency mismatches.
  • Documentation

    • Expanded release automation and versioning guidance.
    • Clarified independent engine versioning and release-channel requirements.

Walkthrough

The CLI now supports channel-aware conformance checks that reject dev-build dependencies in releases and validate family engine pins. Composer CLI package references replace the previous Composer runtime references. A new script and workflow synchronize product dependency versions from registry tags and automate update pull requests. Publish workflows pass channel information and update product versions for dev builds. Documentation now describes independent engine versioning, release automation, credentials, troubleshooting, and remaining blockers.

`prisma@8.0.0-rc.3` shipped depending on `@prisma/composer@0.6.0-dev.16`
and `@prisma/orm-toolchain@8.0.0-rc.1-dev.40`. Both were interim pins
that nothing moved off, and no check refused them.

The rule is now explicit and enforced: a release of the CLI depends only
on released versions of composer and the ORM; a dev build of the CLI
depends on their dev builds. The committed manifests hold the released
versions and a workflow keeps them current, so main stays releasable and
every version change is a reviewed pull request. A dev publish rewrites
them to each product's `dev` tag in CI, ephemerally, exactly as it
already rewrites the CLI's own version.

Check 4 of the conformance suite measures the packed manifests against
the run's channel and has no exception mechanism: a suppressed finding
exits 0, which is how rc.3 shipped.

The shell also moves from `@prisma/composer` to `@prisma/composer-cli`.
The library dropped its `./family` export when composer split its CLI
out, so the old pin only worked because it was a dev build from before
the split. The new package peers the engine at the version this repo
ships, which removes one of the two engine copies an install resolved.

…hed"

Six review findings, all valid. The one that mattered: every `npm view`
failure was converted into "this package is not published", so a registry
outage, an auth failure or a missing npm would let a dev publish keep the
committed release versions and ship a dev build pinned to them.

Only a missing package now means "nothing to move to". Reading dist-tags
per package instead of resolving one tag at a time makes a wrong tag name
distinguishable from a missing package — and that immediately found a
bug carried over from the old script: it read `next` for
@prisma/orm-toolchain, which has never had that tag, so it would have
silently never updated the ORM even once the token existed. All three
products publish releases under `latest`, verified against the registry.

The rest are documentation corrections, each replacing a claim about the
target state with what is actually deployed: the product repositories do
not notify this repo yet, an expired token fails the run rather than
failing silently, pointing at released versions is not the same as being
ready to release, and a routine push publishes a dev build rather than
nothing. The version-update workflow's own token drops to `contents:
read`, since every write goes through DEPLOY_GITHUB_TOKEN.

All six findings are addressed in 7878b69, replies on each thread. The registry-lookup one was a real defect and fixing it exposed a second: the watched-package table read a next dist-tag for @prisma/orm-toolchain that has never existed, so that package would never have been updated.

@wmadden-electric I verified commit 7878b69.

The registry lookup now fails for outages, authentication failures, DNS failures, and missing npm. Only an E404 package absence is skipped.

The script now reads complete dist-tag maps. It fails when a configured tag is missing. This prevents a bad tag from silently preserving stale pins.

@prisma/orm-toolchain now uses latest for release updates. This fixes the nonexistent next tag mapping.

The workflow permissions and documentation corrections also match the implementation. I found no additional issues in this follow-up review.

Review rate limited.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

The v8 RC line publishes under `next` (operator, 2026-08-17), but
@prisma/orm-toolchain has no `next` tag on the registry today — only
`latest` at 8.0.0-rc.1 — and prisma/prisma's own versioning doc still
describes the RC line moving `latest`. Hard-coding either name is wrong
in one of the two worlds.

Each watched package now carries candidate release tags, most-preferred
first, and the first tag the package actually publishes wins. The ORM
asks for `next` then `latest`, so rc.2 is picked up whichever tag it
lands on. A package that publishes none of its candidates still fails
the run rather than looking like "nothing to update".

The products' packages are all new, so no pre-8 audience needs
protecting and their releases go straight to `latest`, pre-release
versions included (operator, 2026-08-17). Holding `latest` back behind
`next` matters for exactly one package: the bare `prisma` name, which
this repo publishes and whose `latest` serves 7.9.1 to everyone who
types `npm install prisma`.

The candidate-tag list stays. A single-entry list still fails loudly
when the tag is missing, which is the property that caught the ORM
never being updated.

composer published 0.7.0 and prisma/prisma published 8.0.0-rc.2, both
declaring @prisma/cli-engine@0.1.1 as an exact peer. The committed
manifests now hold those, so the release channel reports nothing at all:
no dev dependencies, one engine in the installed tree, no recorded
exceptions left.

The exception list is empty rather than absent, so adding an entry is a
decision someone has to argue for instead of a way to get green. The
stale TODO in src/cli.ts goes with it — the two-engine defect it
described is closed.
