pp-blu-ray
The disc-collector's CLI for Blu-ray.com — offline catalog, live deals, and a price-drop watchlist with zero account required. Trigger phrases: `blu-ray`, `bluray`, `4k uhd`, `disc collection`, `blu-ray deal`, `price drop alert blu-ray`, `what 4k comes out`, `blu-ray release calendar`, `use blu-ray`, `run blu-ray-pp-cli`.
Why this skill is useful
Adds niche commands for managing a Blu-ray collection, including local price tracking and catalog drift analysis that the AI wouldn't generate on its own.
What it needs
Requires blu-ray-pp-cli installed locally. About 9k tokens when loaded. Last updated 2026-08-06. 1,890 stars on the source repository.
What this skill does
Blu-ray.com — Printing Press CLI Prerequisites: Install the CLI This skill drives the blu-ray-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: blu-ray-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. Sync the public Blu-ray.com sitemap into a local SQLite + FTS5 index and search ~400,000 releases without a network round-trip. Track prices with a local watchlist that pings you on new historical lows. Pipe everything as JSON. When to Use This CLI Reach for blu-ray-pp-cli whenever an agent or user needs to query the Blu-ray.com disc database: resolving titles to release ids, comparing editions across formats, scanning deals across retailers, tracking prices on a wishlist, or building a catalog drift report. The CLI is read-only against Blu-ray.com — it never logs in, never posts, and respects every robots-disallowed path. Pair it with cron or launchd to get daily price alerts without a third-party service. 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. …
