Use for diagnosing and fixing Claude Code / Claude Desktop plugin staleness, stuck updates, and cache drift. Triggers when a plugin keeps loading an old version, when `claude plugin update` or `claude plugin marketplace update` says "already at latest" but isn't, when a `plugin.json` version bump doesn't show up in Desktop's "Update available" badge, when an installed plugin's files are missing on disk, when a manually-deleted plugin breaks Desktop, when skills/commands won't refresh after marketplace pushes, or when the user mentions `cpd`, `claude-plugin-doctor`, or drift kinds like `marketplace-update-broken`, `bump-needed`, `badge-only-needed`, `registration-drift`, `skills-plugin-stuck`. Runs the `cpd` CLI to pinpoint which of six cache layers is stale and recommends the safest fix, confirming before any destructive action.

From the source SKILL.md

cpd is a read-only diagnostic CLI for the Claude Code / Claude Desktop plugin system. There are six independent cache layers (marketplace clone, plugin install snapshot, per-account Claude Cowork session mirror, backend marketplace catalog, Cowork in-app install / "Personal plugins", standalone Claude Code remote SSH sync) and any one of them can be stale on its own. Most "the plugin is still loading the old version" reports are one specific layer being stale — cpd walks all six and tells you which.
