Use when asked to sweep, clean up, or revisit pnpm overrides and minimumReleaseAge exclusions in platform/pnpm-workspace.yaml — unwinding a matured temporary CVE pin once its fix has cleared the 7-day window, or removing an override the dependency graph has made redundant. This skill only sweeps existing pins; it does not author new CVE fixes.

Archestra Dependency Override Sweep

CVE fixes for transitive or pinned deps — the ones Dependabot can't auto-fix — live as overrides in platform/pnpm-workspace.yaml. Two kinds of cruft collect there, and this skill removes them:

  • Matured temporary pins. When a fix is newer than the repo's 7-day minimumReleaseAge (10080 minutes) it's pinned exact and the package is added to minimumReleaseAgeExclude so pnpm installs it anyway. Those are temporary — unwind them once the fix has cleared the window.
  • Redundant overrides. As the dependency graph catches up, an override stops doing anything: the package already resolves to a compliant version without it.

Out of scope: authoring new CVE fixes (adding overrides for freshly-flagged advisories). This skill only sweeps overrides that already exist.

Work from platform/. Make one override change at a time — one matured pin unwound (Mode A) or one redundant override removed (Mode B), never several and never one of each. Smallest blast radius, trivially revertible, easy to bisect.

Mode A — unwind one matured temporary pin

  1. Find the temporary entries: the TEMPORARY: comment blocks and the minimumReleaseAgeExclude list (ignore non-CVE excludes like next / @next/* — they're kept for other reasons).
  2. Pick one whose pinned fix version has now been published ≥7 days ago — check npm view <pkg> time --json rather than trusting the comment's date. If unsure, proceed anyway: pnpm is the backstop — re-resolving rejects a still-immature version with ERR_PNPM_NO_MATURE_MATCHING_VERSION, which simply means leave it quarantined.
  3. For that one package: drop it (and any @scope/* siblings) from minimumReleaseAgeExclude along with its TEMPORARY: comment, and relax its exact override pin to a >= floor at the fix version — or drop the override entirely if the graph resolves to a non-vulnerable version without it. Leave pins held for a non-CVE reason alone.
  4. Verify (below).

Mode B — drop one redundant override

  1. Pick one override to test. Remove its line from overrides: (and any comment that documents only that line).

  2. Re-resolve: corepack pnpm install --lockfile-only --ignore-scripts.

  3. Judge from git diff platform/pnpm-lock.yaml. Redundant ⇒ the diff is empty, or at most drops the override's own line from the top overrides: block / flips a specifier: reflection. What proves the override was load-bearing is any edit under the resolution sections — importers (dependency refs), packages (a name@version: key, e.g. + picomatch@2.3.2:), or snapshots (dependency edges); revert if any of those moved. Read the whole diff — don't grep for version: alone, since a shift usually shows up as a new/removed package key, not a version: line.

    pnpm (v11) often leaves the now-orphaned override line in the lockfile's overrides: block, so an empty lockfile diff is the normal redundant result, not a sign nothing ran. That stale line is inert metadata — not a re-applied override — and the --frozen-lockfile check below confirms it. Don't force a full reinstall or pnpm dedupe to purge it; that adds unrelated graph churn for no resolution benefit.

  4. Verify (below).

Watch for false positives: a nested override (e.g. mammoth>@xmldom/xmldom) can look redundant only because a sibling top-level floor (@xmldom/xmldom) is what actually holds it — removing it adds a package key / shifts a version, which the diff exposes. Treat exact pins that hold a version down conservatively; they may be pinning out a regression.

Verify (both modes)

  • No new CVE. Before editing, note the high/critical advisory set from corepack pnpm audit --json (the entries with severity high/critical); after re-resolving, take it again and confirm nothing new appeared. A new advisory → revert.
  • Lockfile + types stay sound: 
    corepack pnpm install --frozen-lockfile --prefer-offline --ignore-scripts   # must say "up to date"
corepack pnpm install --fix-lockfile --lockfile-only --ignore-scripts        # immature-deps check, must not error
corepack pnpm --filter @backend --filter @frontend type-check
  • pnpm audit only sees npm-package advisories, not base-image OS packages — treat it as a local proxy, not the last word on the image's CVEs.

Notes

  • After a sweep the lockfile stays at the resolved version regardless of removing the exclusion; the exclusion only governs install-time maturity enforcement.
  • Overrides come in several shapes — plain (lodash: '>=4.18.0'), exact pins (vite: 7.3.5), major-scoped selectors (ws@>=8, picomatch@<4), and nested (mammoth>@xmldom/xmldom). The lockfile-diff check in Mode B is what actually proves a removal is safe, whatever the shape.
  • minimumReleaseAge (7 days) is a supply-chain defense; only bypass it via the exclude list for a known security fix, and undo it promptly — that's Mode A.
