Sandbox Npm Install

Category: Dev Tools · Sub-category: package-mgmt

lang:javascripttool:docker

Install npm packages in a Docker sandbox environment. Use this skill whenever you need to install, reinstall, or update node_modules inside a container where the workspace is mounted via virtiofs. Native binaries (esbuild, lightningcss, rollup) crash on virtiofs, so packages must be installed on the local ext4 filesystem and symlinked back.

What this skill does

Sandbox Npm Install is a community-contributed Claude Code skill in the package-mgmt sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sandbox-npm-install/ and loads when your prompt matches the skill's trigger.
