Dependency Maintenance

Use this workflow to maximize safe dependency progress without changing the repository's package-manager contract or hiding remaining risk.

Preflight

1. Read repo instructions first: AGENTS.md, CLAUDE.md, package-specific instructions, and CONTRIBUTING.md.
2. Detect the package-manager contract from lockfiles, packageManager, CI, deploy config, and package-manager guard scripts:
   • npm repo: use npm, preserve package-lock.json, and validate with npm ci.
   • pnpm repo: use pnpm, preserve pnpm-lock.yaml, pnpm-workspace.yaml, catalogs, and overrides.
   • Do not introduce a different lockfile, workspace file, package-manager metadata, or install command.
3. Check branch and worktree state with git status --short --branch. If unrelated changes are present, use an isolated worktree or avoid touching those files.
4. Read .nvmrc, .node-version, engines, .npmrc, CI workflows, deploy config, and dependabot.yml.
5. Capture the baseline: outdated report, audit report, lockfile state, and relevant validation commands.

Policy

• Treat release-age and cooldown rules as hard gates. Compute exact cutoff timestamps before selecting versions.
• In pnpm repos, minimumReleaseAge is a maturity window in minutes. Treat the configured minimumReleaseAgeExclude list as read-only: respect the existing entries, but never add or widen it to push a fresher version through — the maturity window is a hard gate, not a hurdle to bypass.
• Treat npm/pnpm dependency updates as owned by this skill. Do not re-enable Dependabot npm/pnpm package-ecosystem jobs unless the user explicitly asks; GitHub Actions, Docker, and other non-JavaScript ecosystems may remain under Dependabot.
• Pin exact versions (mandatory). Every npm/pnpm dependencies/devDependencies specifier must be an exact pin, never a ^ caret or ~ tilde range. Floating ranges silently pull unreviewed releases and widen the supply-chain attack surface, so a single exact version is the only safe and reproducible default. When a bump touches a manifest, also tighten any pre-existing ^/~ range on that package to an exact pin. The exception is peerDependencies: those declare the version range a consumer must satisfy (the package never installs them itself), so pinning them exact invents false incompatibilities — leave intentional peer ranges as ranges.
• Preserve reference style otherwise: keep catalog: references, workspace: references, and repo-specific package placement unchanged. Pin the concrete version at the catalog definition so consumers stay on catalog:.
• Default PR scope is eligible patch and minor updates. Major upgrades, risky transitive fixes, and broad migrations get tracking issues unless the user explicitly approves doing them now.
• Prefer official migration guides, changelogs, package registry metadata, and advisory pages for decisions that affect risk.

Inventory

Build an inventory from direct dependencies, dev dependencies, peer dependencies, optional dependencies, catalogs, overrides, lockfiles, and audit output.

Use native commands first:

npm outdated --json || true
npm audit --json || true
npm explain <package>
npm ls <package>

pnpm outdated -r --format json || true
pnpm audit --json || true
pnpm why <package> -r

When registry-age gates matter, use the bundled helper as a reproducible first pass:

node <skill-dir>/scripts/eligible-updates --manager auto --days 3

Replace <skill-dir> with the directory containing this SKILL.md. Adjust --days or --minutes to match the repo policy.

Triage

Classify every candidate before changing files:

• Safe now: patch/minor, older than cutoff, peer-compatible, and locally validatable.
• Blocked non-major: too fresh, peer-conflicting, runtime-breaking, upstream-pinned, or requiring nontrivial code/config migration.
• Major migration: semver-major or framework/toolchain migration that needs a dedicated issue.
• Audit-only blocked: no patched version, incompatible transitive major, bundled dependency, or upstream package must move first.
• Removable: unused dependency that should be deleted instead of bumped.

Group tightly coupled packages together when separate bumps are likely to create peer, type, or runtime friction.

Apply

• Update catalogs before workspace manifests when dependencies are shared through catalog:.
• In npm repos, update package.json and regenerate package-lock.json with npm. Prefer lockfile-only install when appropriate, then validate with clean install.
• In pnpm repos, regenerate pnpm-lock.yaml with normal pnpm install flow. Do not bypass minimumReleaseAge.
• Preserve package-manager script safety settings such as engine-strict, ignore-scripts, LavaMoat allow-scripts, and only-allow.
• Keep code/config changes minimal and only when required by the dependency update.
• If a supposedly safe update breaks validation, revert just that candidate and document why it moved to blocked work.

Overrides

Treat overrides as temporary exceptions:

• Remove stale overrides after direct bumps when they no longer affect resolution or audit posture.
• Keep or add only targeted overrides that are compatible with the dependent package and materially improve security or toolchain behavior.
• Avoid broad overrides for transitive major jumps unless upstream compatibility is proven.
• Document every kept override with package path, advisory or compatibility reason, current resolution, target resolution, and remaining risk.

Refresh overrides after the direct bumps land, so you only keep exceptions that are still required. Let natural resolution catch up first, then keep overrides only for advisories that remain. The flow is the same regardless of package manager, but the exact commands differ, so use the ones in the matching reference file:

1. Remove the existing overrides block from the package manager's source config. For pnpm, inspect the repo first: the live block can be top-level overrides in pnpm-workspace.yaml, pnpm.overrides in package.json, or resolutions. For npm, use overrides in package.json. Do not edit generated lockfile override metadata by hand.
2. Reinstall so resolution settles without the overrides.
3. Apply the package manager's audit fix. For npm, run npm audit fix without --force, which stays non-major. For pnpm, run pnpm audit --fix; on pnpm 10 this can write targeted overrides pinning the patched versions, while older pnpm versions may require adding targeted exact overrides manually from the remaining audit output. If pnpm edits minimumReleaseAge, minimumReleaseAgeExclude, or related maturity-gate settings, revert those edits immediately; do not use audit fix to bypass the maturity gate.
4. Reinstall again so the lockfile reflects the fixed tree.

Then inspect the result — do not trust the audit fix blindly:

• Any advisory still reported needs a deliberate, documented override pinned to an exact version (Policy); anything now resolved should stay removed.
• An audit fix can pin a transitive dependency to a new major. Before keeping such an override, confirm the dependent package actually supports it; otherwise revert it and track the advisory as blocked (see the transitive-major rule in references/pnpm.md).
• In pnpm repos, minimumReleaseAge also gates overrides: pnpm refuses an exact-version override still inside the maturity window and can silently fall back to an older in-range version that is still vulnerable. Confirm with pnpm why <pkg> -r plus a re-audit that the intended patched version actually landed. If the only patched version is still inside the maturity window, treat the advisory as blocked and track it until the version matures — never widen minimumReleaseAgeExclude to force it in. If pnpm audit --fix adds such an exclusion, revert it; do not accept the silent, still-vulnerable fallback or compensate for maturity failures with config changes.
• Re-run validation, because dropping or changing overrides can shift transitive versions across the workspace.

See references/pnpm.md and references/npm.md for the per-manager commands (on pnpm 10 pnpm audit --fix rewrites overrides automatically; npm never writes overrides, so its flow relies on npm audit fix without --force plus manual targeted overrides).

Validation

Run the narrowest meaningful checks first, then broaden by blast radius:

• install or clean install
• audit after changes
• lint, typecheck, build, and tests
• repo-specific checks such as Docusaurus prebuild/build, Turbo filters, Prisma generate, Playwright/Storybook browsers, Docker builds, Foundry/forge, subgraph codegen/tests, or generated-doc checks

If a command cannot run, report why. If CI fails, inspect the actual logs and classify the failure as introduced by the update, exposed baseline debt, or external/non-actionable.

Open The PR

Open the PR only after local validation is green. Opening a PR is an outward-facing action, so commit the work on a dedicated branch, then pause and confirm with the user before pushing and creating the PR.

• Branch from the repo's base branch, stage the manifest and lockfile changes together, and commit with the repository's Conventional Commit format. Do not assume a universal type or scope; use the repo-approved prefix and set the description to refresh dependencies.
• Open a PR.

Open English follow-up issues for deferred major upgrades or blocked migration streams. Each issue should include official docs, current and target versions, expected code areas, migration plan, validation, rollout risk, and rollback notes.

Stop And Ask

Pause before contract deployments, public API breakage, package-manager migration, broad refactors, invalid override trees, or CI failures that suggest a cross-cutting regression.
