mvanhorn Steam Web — Printing Press CLI
Prerequisites: Install the CLI
This skill drives the steam-web-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 steam-web --cli-only - Verify:
steam-web-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):
go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/steam-web/cmd/steam-web-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
Pick this CLI when an agent is asked to query Steam profile, library, achievement, or news data and the question crosses entities — anything joining friends with owned games, achievements with global rarity, or news with a date filter. The local SQLite store turns those questions into one SQL query instead of an N+1 fanout. Every other Steam tool is single-shot read-once; this one compounds. For pure single-endpoint reads (one player's profile, one app's news), the per-endpoint MCP tools work too — but the novel commands are where this CLI earns its weight.
Unique Capabilities
These capabilities aren't available in any other tool for this API.
Local state that compounds
library audit— Surface never-launched games, paid titles you bounced off in under 2 hours, and where your hours actually went by genre.Use this when an agent is asked to plan what to play next, justify a refund, or summarize the user's gaming spend.
steam-web-pp-cli library audit 76561197960287930 --bounce --jsonreview-velocity— Reviews per day and voted-up share over a rolling window for one app — date-bucket aggregation over the cursor-paginated appreviews stream.Use this when an agent is asked to track sentiment shifts after a patch, sale, or controversy.
steam-web-pp-cli review-velocity 1245620 --window 30d --jsonnews search— FTS5 search across the title and contents of every news post you've synced, optionally scoped by appid or date range.Use this when an agent is asked to dig up patch notes, devlog mentions, or news around a specific topic across the user's library.
steam-web-pp-cli news search 'patch notes' --since 2026-04-01 --jsonplay-trend— Show concurrent-player count over time for one app as a sparkline plus min/max/last over a rolling window — value scales with how often you sample.Use this when an agent needs to see whether a game's playerbase is growing, falling, or has spiked around an event — sample the count every few hours via cron and the window query becomes meaningful within a week.
steam-web-pp-cli play-trend 1245620 --window 7d --json
Friend-graph intelligence
friends compare— Rank everyone in your friend list by hours spent in a specific game, with throttled fan-out so you don't trip Steam's 25 req/s budget.Use this when an agent is asked 'who in my friends has the most hours in ' or 'who owns this and never played'.
steam-web-pp-cli friends compare 1245620 --my-steamid 76561197960287930 --agent --select results.persona_name,results.playtime_hourslibrary compare— Set operations across two libraries — what's mine-only, what's theirs-only, what's shared with playtime delta.Use this when an agent is asked 'what games do my friend and I both own' or to plan a co-op session.
steam-web-pp-cli library compare 76561197960287930 --my-steamid 76561197960287930 --shared --jsoncurrently-playing— Show which friends are in-game right now and what they're playing — one batched API call across the friend list, no fanout.Use this when an agent is asked 'who is online and playing what' or to power a status panel.
steam-web-pp-cli currently-playing --my-steamid 76561197960287930 --jsonachievement-leaderboard— Rank your friends by achievement completion percentage for one app, throttled fan-out via the same limiter that powers friends compare.Use this when an agent is asked 'who in my friends is closest to 100% in ' or to seed a competitive completion challenge.
steam-web-pp-cli achievement-leaderboard 1245620 --my-steamid 76561197960287930 --json
Achievement intelligence
next-achievement— Across your entire library, surface the achievement with the highest global unlock percentage that you still don't have.Use this when an agent is asked 'what should I go unlock next' or to recommend low-effort achievement progress for completionists.
steam-web-pp-cli next-achievement --steamid 76561197960287930 --limit 10 --jsonachievement-hunt— Render the full achievement schema for one app side-by-side with your unlock state and the global rarity of each achievement in one table.Use this when an agent needs the full unlock landscape for one game to plan a completion run.
steam-web-pp-cli achievement-hunt 1245620 --steamid 76561197960287930 --locked --jsonrare-achievements— Surface your rarest achievement unlocks across all owned games — the inverse of the next-achievement query, sorted by ascending global percentage.Use this when an agent is asked to summarize what the user is proud of, or to power a profile-flex panel.
steam-web-pp-cli rare-achievements --steamid 76561197960287930 --limit 10 --json

Finding the right command
When you know what you want to do but not which command does it, ask the CLI directly:
steam-web-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.

Throttled fan-out to identify dormant owners — the people most likely to actually play if invited.
Plan a completion run on one game
steam-web-pp-cli achievement-hunt 1245620 --steamid 76561197960287930 --locked --agent --select achievements.display_name,achievements.global_pct
Surfaces every locked achievement plus its global rarity so you can rank effort vs. reward.
Find low-hanging fruit across your whole library
steam-web-pp-cli next-achievement --steamid 76561197960287930 --limit 10 --json
Cross-library SQL — the ten achievements with the highest global unlock rate that you still don't have.
Audit your backlog after a sale
steam-web-pp-cli library audit 76561197960287930 --never-launched --json
Reveals what you bought and didn't open; pairs well with library audit --bounce for the under-2h paid set.
Search your synced news feed for a topic
steam-web-pp-cli news search 'mod support' --since 2026-04-01 --json
FTS5 search over every news post you've synced — useful for tracking when devs ship features you care about across all your owned games.
Auth Setup
Standard Steam Web API key auth: get one at https://steamcommunity.com/dev/apikey and set STEAM_WEB_API_KEY in your environment. The key is sent as a ?key= query parameter on every request. Some endpoints (server time, app list, news) require no auth at all and work without a key. The IAuthenticationService endpoints in the spec are NOT for Web API auth — they implement Steam's interactive QR-code login flow. They remain reachable via the CLI subcommand and the MCP code-orchestration pair for completeness but should not be used as part of normal Web API workflows.
Run steam-web-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:steam-web-pp-cli iauthentication-service begin-auth-session-via-credentials --account-name example-resource --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
Explicit retries — use
--idempotentonly when an already-existing create should count as success
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 — piped/agent consumers get pure JSON on stdout.
Agent Feedback
When you (or the agent) notice something off about this CLI, record it:
steam-web-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
steam-web-pp-cli feedback --stdin < notes.txt
steam-web-pp-cli feedback list --json --limit 10
Entries are stored locally at ~/.steam-web-pp-cli/feedback.jsonl. They are never POSTed unless STEAM_WEB_FEEDBACK_ENDPOINT is set AND either --send is passed or STEAM_WEB_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.
steam-web-pp-cli profile save briefing --json
steam-web-pp-cli --profile briefing iauthentication-service begin-auth-session-via-credentials --account-name example-resource
steam-web-pp-cli profile list --json
steam-web-pp-cli profile show briefing
steam-web-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.
