# 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 `$HOME/.local/bin` on macOS/Linux and `%LOCALAPPDATA%\Programs\PrintingPress\bin` on Windows:
   ```bash
   npx -y @mvanhorn/printing-press-library install blu-ray --cli-only
   ```
2. Verify: `blu-ray-pp-cli --version`
3. Ensure the reported install directory is on `$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 1.26.3 or newer):

```bash
go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/blu-ray/cmd/blu-ray-pp-cli@latest
```

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.

## 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.

## Unique Capabilities

These capabilities aren't available in any other tool for this API.

### Local state that compounds
- **`search`** — Instant offline search across every Blu-ray release in Blu-ray.com's published sitemap (~400k+ entries). Faster than the site's JS-rendered search and works without a network round-trip after one sync.

  _Reach for this whenever an agent needs to resolve a title to a release id, list every edition of a film, or filter the catalog by year/format/country. Single round-trip vs. the dozens of network hits the website does._

  ```bash
  blu-ray-pp-cli search 'fight club' --format 4k --year 2025 --json
  ```
- **`watch check`** — Local watchlist of release ids; re-scans Blu-ray.com deals on demand and alerts when any watched disc hits its target price or a new historical low.

  _Use this whenever a user wants notifications about disc prices without polling third-party services. Pairs naturally with cron or a launchd job._

  ```bash
  blu-ray-pp-cli watch add 9929 --target-price 14.99 && blu-ray-pp-cli watch check --agent
  ```
- **`drift`** — Diffs today's sitemap against the last sync and surfaces 'new in catalog this week', 'removed', and 'metadata changed' so collectors don't miss announcements.

  _Use this to catch up after being away from the site for a week, or to build a weekly digest of what dropped, what got delayed, and what got pulled._

  ```bash
  blu-ray-pp-cli drift --since 2026-05-01 --kind bluray --json
  ```

### Decision support
- **`editions`** — Given a movie umbrella id, lists every disc edition (4K UHD, Blu-ray, Steelbook, Director's Cut, country variant) with release date, list price, current price, and Blu-ray.com community rating in a single view.

  _Use this when a user is deciding which edition of a film to buy (4K vs Blu-ray, Criterion vs Arrow, region A vs region B). Surfaces the trade-off at a glance._

  ```bash
  blu-ray-pp-cli editions 9929 --country US --json
  ```
- **`history`** — Shows per-retailer price history for a release id, captured automatically by watch check + deals --record. Optional inline ASCII spark plot.

  _Use this to know whether the current 'deal' is actually historically low, or just a small dip. Distinguishes real bargains from clickbait._

  ```bash
  blu-ray-pp-cli history 9929 --retailer amazon --plot
  ```

### Round-tripping
- **`upc`** — Resolves a CSV of UPC codes (e.g. the comma-separated export Blu-ray.com itself produces) back to local release records, hydrating titles, formats, ratings, and current prices.

  _Use this whenever a user is moving a collection between tools (Blu-ray.com to Trakt, CLZ, Letterboxd) or building a watch-list from a barcode scan._

  ```bash
  blu-ray-pp-cli upc ./my-collection.csv --dry-run --json
  ```

### Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

```bash
blu-ray-pp-cli which "<capability in your own words>"
```

`which` resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code `0` means at least one match; exit code `2` means no confident match — fall back to `--help` or use a narrower query.

## Hand-written Extensions

These commands are declared by the spec author and require separate hand-written wiring; the generator does not emit Cobra registration for them. They are listed here for discoverability and are intentionally outside `## Command Reference` so the verify-skill unknown-command check does not treat them as generator-owned paths.
