+# PNPM Upgrade Package
+
+Use this workflow when a user wants to upgrade a dependency in the Langfuse
+pnpm workspace.
+
+## Workflow
+
+1. Collect missing inputs.
+   - Ask for the package if missing.
+   - Ask for the target version if missing.
+   - If the user says `latest`, resolve the real registry latest first.
+
+2. Run the main helper once.
+   - Run
+     `node .agents/skills/pnpm-upgrade-package/scripts/check-release-age-window.mjs <package> <targetVersion>`.
+   - Treat this as the single source of truth for:
+     - direct workspace references
+     - root `pnpm.overrides` / `pnpm.patchedDependencies`
+     - latest registry version
+     - latest version installable under the current release-age rules
+     - existing matching `minimumReleaseAgeExclude` entries
+     - exact dependency companions from `dependencies` and `optionalDependencies`
+     - exact peer dependencies that are actually installed in the workspace
+
+3. Handle the transitive-only case before editing anything.
+   - If the helper shows no direct workspace references, run `pnpm why -r <package>`.
+   - Identify the current top-level parent that pulls the package in.
+   - Check whether that parent's current dependency range already permits the
+     requested transitive version.
+   - If the current parent range already covers the requested version, prefer a
+     lock refresh / reinstall path before changing `package.json`.
+   - If the current parent range does not cover the requested version, upgrade
+     the direct parent dependency that pulls the package in.
+   - If a compatible transitive package still stays pinned after the normal
+     refresh path, you may suggest `pnpm dedupe` to the user as an optional
+     manual follow-up, but do not run it automatically and do not require it.
+   - Do not add the transitive package directly unless the user explicitly asks.
+
+4. Ask before changing `minimumReleaseAgeExclude`.
+   - Prefer `package@version` entries.
+   - Only use bare `package` entries after explicit approval.
+   - Ask about exact companion packages only when the helper says they still
+     need a new exclusion.
+   - Treat range-based dependency or peer entries as manual review.
+
+5. Bump at the narrowest useful scope.
+   - `pnpm -w up <package>@<version>` for root-only changes.
+   - `pnpm --filter <workspace> up <package>@<version>` for one workspace.
+   - `pnpm -r up <package>@<version>` only when every current reference should move.
+   - Do not hand-edit `pnpm-lock.yaml`.
+
+6. Validate.
+   - Use the nearest package `AGENTS.md` plus the root verification matrix.
+   - Finish with `pnpm why -r <package>`.
+   - If companions moved too, run `pnpm why -r <companion-package>` for them as well.
+
+## Quick Commands
+
+- Run the single analysis pass:
+  `node .agents/skills/pnpm-upgrade-package/scripts/check-release-age-window.mjs <package> <targetVersion>`
+- Transitive provenance check:
+  `pnpm why -r <package>`
+- Inspect the current parent manifest on the registry:
+  `npm view <parent>@<installedVersion> dependencies peerDependencies optionalDependencies --json`
+- Final graph verification:
+  `pnpm why -r <package>`
+- 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>`

+description: Use when upgrading a dependency in this pnpm workspace, including requests to bump a package to a specific version, compare the registry latest version with the latest version installable under the current minimum-release-age window, or decide whether minimumReleaseAgeExclude in pnpm-workspace.yaml must change. Ask the user for the package name or target version when either is missing.

+# PNPM Upgrade Package
+
+Use this skill for interactive dependency bumps in Langfuse.
+
+## Read Order
+
+- Start with [AGENTS.md](AGENTS.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 a compatible transitive package still stays pinned after the normal
+  refresh path, you may suggest `pnpm dedupe` to the user as an optional manual
+  follow-up, but do not run it automatically and do not require it.
+- 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.
+- 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.
