Use this skill when the user asks to install, refresh, update, or set up Volcano from this plugin.
This installer is adaptive. When run from a Volcano plugin, it uses the plugin-carried skills/ directory as the primary skills source and copies the plugin-carried AGENTS.md into ~/.volcano/AGENTS.md as a stable fallback/reference. When run outside a plugin/manual pathway, it installs AGENTS.md and skills into ~/.volcano so ~/.volcano/skills remains discoverable.
Run the shell block below. It is idempotent:
volcano is already on PATH, it runs volcano upgrade.volcano is missing, it installs @volcano.dev/cli from npm by default.VOLCANO_WEB_URL points at localhost, the GitHub fallback uses the nightly CLI channel for local development.~/.volcano/env.AGENTS.md to ~/.volcano/AGENTS.md as a fallback and keeps skills in the plugin-carried skills/ directory.AGENTS.md plus each skill into ~/.volcano/skills so agents can discover them from the runtime location.set -eu
