Use this skill when the user wants to make their skills use upx — the fast local-first package runner shipped by universal-plugin. Trigger on phrases like "make my skills use upx", "adopt the upx runner", "speed up npx calls", "switch to upx", or "rewrite npx pins to upx". Rewrites npx <pkg>@<version> references to a caret range on upx (^<major>, or ^0.<minor> for a 0.x pin) across one skill, a named set, or every skill in the project.

Use this skill to diagnose a universal agent plugin — when a runtime loads none of the plugin's skills, when a vendor manifest is missing or looks out of date after a pull, when a build prints warnings nobody has read, or when checking whether what the canonical plugin.json declares still matches what is on disk for Claude Code, Cursor, Codex, and GitHub Copilot CLI. Trigger on "is my plugin set up right", "why isn't my plugin loading", "check the plugin", "are the vendor manifests current", or "what does this plugin declare".

Use this skill to create or change a universal agent plugin — scaffold a new one, adopt an existing vendor-specific plugin or already-shipped skills onto the open Agent Plugins Specification, or add and remove vendors and components on the canonical plugin.json that drives Claude Code, Cursor, Codex, and GitHub Copilot CLI. Trigger on "init a plugin here", "make my Claude Code plugin work in Cursor", "convert this to the open plugin standard", "turn these skills into a plugin", "add Codex support", or "add a hooks component".

Use this skill to let people install a plugin straight from its own repository — generate the local marketplace catalogs Claude Code, Codex, GitHub Copilot CLI, and Cursor read, and write the README install section that tells users what to type. Trigger on "set up a local marketplace", "let users install this from my repo", "generate marketplace catalogs", "add install instructions to the README", "how do people install this plugin", or "make this repo installable".

Move a repository-root universal agent plugin into its npm package so the package distributes its manifest, vendor manifests, skills, and agents. Use this skill when packaging an existing plugin for npm, relocating a top-level plugin into a package, or fixing a package that omits plugin assets, even if the user says only 'ship this plugin through npm' or 'move the plugin into the package.'

Use this skill whenever the user wants to publish, release, submit, or share a plugin to the universal plugin marketplace so it works across Claude Code, Cursor, Codex, and GitHub Copilot CLI. Trigger on phrases like "publish my plugin", "submit to marketplace", "release plugin", "list my plugin", "share my plugin", or any mention of getting a plugin into the universal registry. The plugin should already be packaged before using this skill.

Use this skill to remove a universal agent plugin's artifacts — delete the generated vendor manifests for Claude Code, Cursor, or Codex, clear a stale or shadowing manifest left by an older build, or take the whole plugin out of a project. Trigger on "delete the generated manifests", "remove the vendor manifests", "clean the plugin build output", "drop Codex support", "get rid of this plugin", or "stop shipping this plugin".

Use this skill when upgrading pinned npx universal-plugin@<version> calls across a project to a newer version.
