PNPM Upgrade Package

Use this skill for interactive dependency bumps in Langfuse.

Read Order

• Use this SKILL.md for the end-to-end workflow.
• Run the main helper once at the start of the upgrade: node .agents/skills/pnpm-upgrade-package/scripts/check-release-age-window.mjs <package> [targetVersion]

Apply This Skill

• Ask for the package name if the user did not provide one.
• Ask for the target version if the user did not provide one.
• Run the main helper once as the first analysis step and use that single output for scope, exclusion decisions, and the final bump.
• If the target package is not directly declared anywhere, run pnpm why -r <package> to find which direct dependency brings it in, then inspect whether the current top-level parent already allows the requested transitive version via its dependency range.
• If the current parent range already covers the requested transitive version, prefer a lockfile refresh / reinstall path over bumping the parent manifest.
• If the current parent range does not cover the requested transitive version, upgrade that parent dependency instead of adding the target package directly unless the user explicitly wants that.
• If pnpm will not move an already-allowed transitive version, a scoped overrides entry in pnpm-workspace.yaml may be used as a temporary resolution tool. Before finishing, prove whether the override is still required: remove it, run pnpm install, then run pnpm dedupe. Inspect the diff after each generated change. If the target version remains without the override, do not keep the override; keep or restore it only when pnpm reverts or drifts from the requested version without it.
• Never manually edit pnpm-lock.yaml; regenerate lockfile changes with pnpm commands only. If a lockfile-only refresh causes unrelated churn, adjust the pnpm command and rerun instead of patching the lockfile by hand.
• After fixing or upgrading a package, run pnpm dedupe. Always inspect the diff after dedupe and revert that generated attempt if it introduces unrelated churn.
• Resolve the registry latest version, but do not silently upgrade to latest unless the user asked for latest.
• Compare the target version with the latest version installable under the current minimumReleaseAge window.
• Before generating lockfile changes, run pnpm install --dry-run --ignore-scripts to catch resolver and policy failures without writing pnpm-lock.yaml or node_modules.
• Inspect any dry-run "would make changes" output as baseline resolver drift before deciding which write command is safe.
• Ask before adding minimumReleaseAgeExclude entries for the target package, exact dependency companions from dependencies or optionalDependencies, or locally installed exact peer dependencies.
• Finish with pnpm why -r <package> to confirm that only the intended version remains in the workspace.
• In the final response, include a copy-pasteable human commit command using the resolved package name and target version. Use a branch-safe package slug for scoped packages, but keep the exact package name in the commit message: git switch -C deps/bump-<package-slug>-to-<version> && git commit -m "chore(deps): bump <package> to <version>" --no-verify

Quick Commands

• Analysis pass: node .agents/skills/pnpm-upgrade-package/scripts/check-release-age-window.mjs <package> <targetVersion>
• Transitive provenance / final graph verification: pnpm why -r <package>
• Inspect a current parent manifest on the registry: npm view <parent>@<installedVersion> dependencies peerDependencies optionalDependencies --json
• Preflight resolver/policy check: pnpm install --dry-run --ignore-scripts
• Optional lockfile cleanup: pnpm dedupe
• Bump in the root workspace: pnpm -w up <package>@<version>
• Bump in one workspace: pnpm --filter web up <package>@<version>
• Bump everywhere that should move together: pnpm -r up <package>@<version>
• Verify temporary override removal: remove the override, then run pnpm install and pnpm dedupe
• Human commit helper: git switch -C deps/bump-<package-slug>-to-<version> && git commit -m "chore(deps): bump <package> to <version>" --no-verify
