What this skill does
npm — Printing Press CLI Prerequisites: Install the CLI This skill drives the npm-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: npm-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead: If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. Research npm packages by metadata, downloads, maintainers, freshness, and dependency risk. When Not to Use This CLI Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis. HTTP Transport This CLI uses Chrome-compatible HTTP transport for browser-facing endpoints. It does not require a resident browser process for normal API calls. Command Reference intelligence — Agent-first package research npm-pp-cli package <name> — Summarize one package with latest version, maintainers, dependencies, publish freshness, and last-month downloads. npm-pp-cli compare <package> [package...] — Compare packages by adoption, freshness, maintainers, and dependency surface. npm-pp-cli risk <package> — Score package maintenance and adoption risk with explicit signals. …
