In @.changeset/warn-about-yarn-workspaces-field.md:
- Line 5: Update the release note to state concisely that pnpm warns when the
root package.json contains a non-empty array-form workspaces field without a
pnpm-workspace.yaml; omit the implementation rationale and leave object-form
workspaces unmentioned or explicitly silent.
In `@pnpm/crates/cli/src/cli_args/yarn_workspaces_field/tests.rs`:
- Around line 8-9: Expand the tests around declares_in and the install entry
points to verify the user-visible warning text, confirm the warning is
suppressed when workspace_dir is set, and cover invocation through both install
paths. Retain the existing predicate coverage while asserting the complete
warning behavior rather than only declares_yarn_workspaces.

Integrated-Benchmark Report (Linux)Commit: Regular scenarios report direct and pnpr installs. The peer-heavy resolver scenario compares current Rust, main Rust, and TypeScript pnpm. Bencher consumes pacquet@HEAD and pnpr@HEAD. The tables below show mean ± σ; Bencher thresholds on the minimum latency, which is far less perturbed by shared-runner contention (noise only adds time). Scenario: Isolated linker: fresh restore, cold cache + cold store

}Scenario: GVS linker: fresh restore, hot cache + hot storeSame install as the isolated fresh-restore hot/hot scenario, into the shared virtual store — the layout pnpm 12 installs into by default. Comparable to that scenario head-to-head.

pnpm 11 warns when the root package.json carries Yarn's `workspaces` field and the project has no `pnpm-workspace.yaml`; pnpm 12 did not, so a repository converted from Yarn installs as a single project with no hint about why none of its projects were linked. The warning is emitted next to the existing legacy `pnpm` field warning, from both install entry points, and reuses pnpm 11's wording so the two versions read the same. It stays silent inside a workspace, where pnpm-workspace.yaml already selects the projects. Related to pnpm#2255
The unit tests exercised the predicate only, so the warning itself — its wording, its two call sites, and its silence inside a workspace — had no test, which is also the patch coverage codecov flagged. Add an integration test that runs the CLI: a first install warns, a repeat install taking the up-to-date short-circuit warns, and neither a workspace nor Yarn's object spelling says anything. Also state the trigger in the changeset: only a non-empty array-form `workspaces` field warns.
…arnings The Yarn `workspaces` warning carried its own copy of the root-manifest reader the `pnpm` field warning already had, so the up-to-date install fast path opened and parsed package.json twice. Both warnings now take the manifest from one shared reader in `package_manager`, and the fast path reads it once. Move the module declaration into the ordered block at the top of `cli_args`: appended to the private `mod` block at the bottom, it fails `perfectionist::arbitrary_source_item_ordering`, which no other local check reports. Build the repeat-install test's second command the way the rest of the suite does, so the ambient pnpm configuration and the update notifier stay out of it. Reword the changeset to end with the issue link. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]> Claude-Session: https://claude.ai/code/session_01HRDQwbCAWvnkN2zm3d5Mwa

Summary
pnpm 11 warns when the root
package.jsoncarries Yarn'sworkspacesfield and there is nopnpm-workspace.yaml(pnpm11/config/reader/src/index.ts). pnpm 12 has no such check, so a repository converted from Yarn installs as a single project and nothing says why its projects were never linked. Related to #2255.The check sits next to the existing legacy
pnpmfield warning, runs from the same two install entry points, and reuses pnpm 11's wording. It stays quiet inside a workspace.Known limit, kept aligned with pnpm 11: only the array spelling warns. Yarn's object form with a
packageskey stays quiet in both versions.Squash Commit Body
Checklist
Tests
cargo test -p pnpm-cli --lib yarn_workspaces_fieldpasses 4/4. Inverting the emptiness check turns 3 of them red. pnpm 11's predicate and the new check, run over the same six manifest shapes, both warn on 2 of 6.Written by an agent (Claude Code, claude-opus-5).
