What it does

Pp Ikon is an agent skill from mvanhorn/printing-press-library. Printing Press CLI for Ikon Pass reservation availability, pass and voucher lookup, multi-season usage history, and offline change tracking.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.

Example prompts

  • “/pp-ikon”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Read, Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
  2. Verify: ikon-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

What it can do on your machine

Read from SKILL.md and the folder at commit 76de244. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • go
    • claude
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pp Ikon loads about 3k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 1,327 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Ikon Pass — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the ikon-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 ikon --cli-only
  2. Verify: ikon-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:

bash
go install github.com/mvanhorn/printing-press-library/library/travel/ikon/cmd/ikon-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

Use this CLI for anything tied to an Ikon Pass account: checking whether a reservation-required resort (Deer Valley, Jackson Hole, Loon, Snoqualmie) has open days, reviewing your passes and Friends & Family voucher balance, and analyzing your ski history across seasons. It is read-only and offline-first — it mirrors the account API into local SQLite so history, calendars, and change-tracking work without re-fetching.

Anti-triggers

Do not use this CLI for:

  • Do not use this CLI to BOOK, modify, or cancel reservations — it is read-only by design.
  • Do not use it to share or send Friends & Family vouchers — it reports remaining/used counts only.
  • Do not use it for resorts that don't require reservations — most Ikon destinations are walk-on and won't appear in availability.
  • Do not use it to buy or renew a pass — purchasing happens on ikonpass.com.

Unique Capabilities

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

History that compounds
  • most-visited — Rank the resorts you ski most across every season you've held an Ikon Pass, with per-season day counts.

    Reach for this when the user asks where they ski most, how many days they've used over the years, or for a season-by-season breakdown.

    bash
    ikon-pp-cli most-visited --agent
  • changes — After each sync, report which dates opened or closed at your watched resorts since the last snapshot.

    Use this to see what reservation availability shifted day-over-day without re-reading every resort manually.

    bash
    ikon-pp-cli changes
Reservation intelligence
  • plan — Across every reservation-required resort, show which have your target dates open — one call instead of checking four resorts by hand.

    Use this when the user wants to ski a date range and doesn't care which of the reservable mountains it is.

    bash
    ikon-pp-cli plan --from 2026-01-10 --to 2026-01-20
  • calendar — Month grid of open vs full vs blackout vs closed days for a reservable resort.

    Use this to eyeball a whole month of reservation openings for one resort at a glance.

    bash
    ikon-pp-cli calendar 14 --month 2026-01
  • watch — Poll a resort+date and alert the moment a currently-full day frees up.

    Use this when a desired reservation date is full and the user wants to grab it if someone cancels.

    bash
    ikon-pp-cli watch 14 2026-01-17

Command Reference

account — Your account profile

  • ikon-pp-cli account — Your Ikon account profile

availability — Reservation availability for reservation-required resorts

  • ikon-pp-cli availability <resort_id> — Per-pass reservation availability (open/blackout/closed days, remaining slots) for a resort.

benefits — Per-pass benefits

  • ikon-pp-cli benefits <product_id> — Benefits attached to a specific pass

passes — Your Ikon passes / products

  • ikon-pp-cli passes — List the passes and products on your account

reservations — Your current reservations

  • ikon-pp-cli reservations — List your current/upcoming reservations

resorts — Browse Ikon destinations (public — no login required)

  • ikon-pp-cli resorts — List all Ikon destinations with reservation flags, codes, and regions

usage — Pass usage / redemption history

  • ikon-pp-cli usage <product_id> — Season redemption history for a pass (resort, days used, redemption dates). Each pass = one season.

vouchers — Friends & Family shared vouchers

  • ikon-pp-cli vouchers <product_id> — Friends & Family shared-voucher summary (remaining / used) for a pass
Finding the right command

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

bash
ikon-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.

Recipes

Lifetime resort ranking for an agent
bash
ikon-pp-cli most-visited --agent

Returns season-joined day counts per resort as JSON an agent can summarize directly.

Trip planning across reservable resorts
bash
ikon-pp-cli plan --from 2026-01-10 --to 2026-01-20

Shows which of the reservation-required resorts have open days in the window.

Narrow resort data with field selection
bash
ikon-pp-cli resorts --agent --select name,id,reservations_enabled

The resorts payload is large; --select trims it to just the fields an agent needs to resolve a name to an id.

Watch a full date for openings
bash
ikon-pp-cli watch 14 2026-01-17

Polls Jackson Hole for 2026-01-17 and alerts when the date frees up.

Auth Setup

Ikon uses cookie-session auth minted through Auth0 SSO — there's no API key. The public resorts command needs nothing. Everything tied to your account (availability, passes, vouchers, usage) reads your .ikonpass.com session cookie: run ikon-pp-cli auth login --chrome to import it from Chrome, or install the press-auth companion for a controlled one-window capture that survives session expiry. Sessions last roughly a day; re-import when commands start returning 401.

Run ikon-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 — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

    bash
    ikon-pp-cli account --agent --select id,name,status
  • Previewable — --dry-run shows the request without sending

  • Offline-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:

json
{
  "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:

ikon-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
ikon-pp-cli feedback --stdin < notes.txt
ikon-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.local/share/ikon-pp-cli/feedback.jsonl. They are never POSTed unless IKON_FEEDBACK_ENDPOINT is set AND either --send is passed or IKON_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:

SinkEffect
stdoutDefault; 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.

ikon-pp-cli profile save briefing --json
ikon-pp-cli --profile briefing account
ikon-pp-cli profile list --json
ikon-pp-cli profile show briefing
ikon-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.

Argument Parsing

Parse $ARGUMENTS:

  1. Empty, help, or --help → show ikon-pp-cli --help output
  2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
  3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

  1. Install the MCP server:
    bash
    go install github.com/mvanhorn/printing-press-library/library/travel/ikon/cmd/ikon-pp-mcp@latest
  2. Register with Claude Code:
    bash
    claude mcp add ikon-pp-mcp -- ikon-pp-mcp
  3. Verify: claude mcp list

Direct Use

  1. Check if installed: which ikon-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
  2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
  3. Execute with the --agent flag:
    bash
    ikon-pp-cli <command> [subcommand] [args] --agent
  4. If ambiguous, drill into subcommand help: ikon-pp-cli <command> --help.
