mvanhorn 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:
- Install via the Printing Press installer. It defaults binaries to
$HOME/.local/binon macOS/Linux and%LOCALAPPDATA%\Programs\PrintingPress\binon Windows:npx -y @mvanhorn/printing-press-library install blu-ray --cli-only - Verify:
blu-ray-pp-cli --version - Ensure the reported install directory is on
$PATHfor 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:
go install github.com/mvanhorn/printing-press-library/library/media/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.
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.
Unique Capabilities
These capabilities aren't available in any other tool for this API.
Local state that compounds
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.
blu-ray-pp-cli watch add 9929 --target-price 14.99 && blu-ray-pp-cli watch check --agentdrift— 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.
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.
blu-ray-pp-cli editions 9929 --country US --jsonhistory— 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.
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.
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:
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.
blu-ray-pp-cli sync— Sync the published XML sitemap into a local SQLite catalog (~400-450k Blu-ray releases).blu-ray-pp-cli search— Offline title search across the local catalog (FTS5). Filters: --format, --country, --year. Faster than blu-ray.blu-ray-pp-cli editions— Given a movie umbrella id, list every disc edition (4K UHD, Blu-ray, Steelbook, Director's Cut, country)blu-ray-pp-cli watch— Local price-drop watchlist.blu-ray-pp-cli upc— Resolve a CSV of UPC codes (e.g. exported from another collection tool) to local release records, hydrating metadata.blu-ray-pp-cli drift— Diff this week's sitemap against the last sync.

Recipes
Find every 4K UHD release of Fight Club
blu-ray-pp-cli search 'fight club' --format 4k --json --select id,title,year,distributor,country
Offline FTS5 lookup narrowed to 4K — returns each id you can then releases get for full specs.
Daily 4K UHD preorder digest
blu-ray-pp-cli releases new --show comingsoon --format 4k --json --select title,release_date,distributor | jq '.[:20]'
Pipe to jq for the top 20 — drop into cron for a daily digest, no Discord webhook needed.
Spot a real deal vs. a fake one
blu-ray-pp-cli deals --country USA --format 4k --json --select release_id,title,sale_price,percent_off | jq '.[] | select(.percent_off>40)'
Filters deals to >40% off, then cross-reference each release_id with blu-ray-pp-cli history <id> --plot to confirm it's a real historical low.
Import a Blu-ray.com UPC export and enrich it
blu-ray-pp-cli upc ./my-bluray-collection.csv --dry-run --json > collection.json
Round-trips Blu-ray.com's UPC-only export back into structured release data — titles, formats, ratings, current prices.
What dropped this week?
blu-ray-pp-cli drift --since 2026-05-10 --kind bluray --json | jq '.added | length'
Counts new Blu-ray releases added to the catalog in the past 7 days. Replace .added with .removed or .changed for the other slices.
Auth Setup
No account, no API key, no OAuth — Blu-ray.com is read from its published HTML and XML sitemap. The CLI sends a normal browser User-Agent (configurable), throttles itself to stay under the site's per-IP budget (~4,000 pages/day), and never touches robots-disallowed paths.
Run blu-ray-pp-cli doctor to verify setup.
Agent Mode
Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.
Pipeable — JSON on stdout, errors on stderr
Filterable —
--selectkeeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:blu-ray-pp-cli deals --agent --select id,name,statusPreviewable —
--dry-runshows the request without sendingOffline-friendly — sync/search commands can use the local SQLite store when available
Non-interactive — never prompts, every input is a flag
Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests
Response envelope
Commands that read from the local store or the API wrap output in a provenance envelope:
{
"meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
"results": <data>
}
Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.
Agent Feedback
When you (or the agent) notice something off about this CLI, record it:
blu-ray-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
blu-ray-pp-cli feedback --stdin < notes.txt
blu-ray-pp-cli feedback list --json --limit 10
Entries are stored locally at ~/.local/share/blu-ray-pp-cli/feedback.jsonl. They are never POSTed unless BLU_RAY_FEEDBACK_ENDPOINT is set AND either --send is passed or BLU_RAY_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.
Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.
Output Delivery
Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:
| Sink | Effect |
|---|---|
stdout |
Default; write to stdout only |
file:<path> |
Atomically write output to <path> (tmp + rename) |
webhook:<url> |
POST the output body to the URL (application/json or application/x-ndjson when --compact) |
Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.
Named Profiles
A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.
blu-ray-pp-cli profile save briefing --json
blu-ray-pp-cli --profile briefing deals
blu-ray-pp-cli profile list --json
blu-ray-pp-cli profile show briefing
blu-ray-pp-cli profile delete briefing --yes
Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
