See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> Passive Indices — Printing Press CLI Prerequisites: Install the CLI This skill drives the passive-indices-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: passive-indices-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 1.26.5 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. niftyindices.com publishes index levels and constituents; indiapassivefunds.com publishes the ETFs and index funds that track those indices. Nothing links the two. This CLI joins them locally so you can ask "what tracks NIFTY 50, and how well" in one command — plus offline search, agent-native JSON, and a local SQLite layer for historical constituent diffs. When to Use This CLI Use this CLI for anything that requires knowing both an NSE index's current or historical state (level, TRI, valuation, constituents) and the ETFs/index funds that track it — fund selection, cost comparison, tracking-fidelity checks, or sector concentration analysis for passive Indian equity investing. …
