What it does

Pp Activity Japan is an agent skill from mvanhorn/printing-press-library. Inspect known Activity Japan plan IDs or URLs, compare dated prices and sessions, check language-sitemap coverage, and hand off to canonical booking pages. Use for an Activity Japan itinerary shortlist; destination search is access gated.

Its SKILL.md is about 2k 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.

When your agent uses it

  • An Activity Japan itinerary shortlist
  • Destination search is access gated

Example prompts

  • “/pp-activity-japan”

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: activity-japan-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 7fd6e0e. 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
    • 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 Activity Japan loads about 2k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 806 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~2k

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.

Activity Japan plan inspection

Use the installed activity-japan-pp-cli binary. In a source checkout, build with go build -o ./bin/activity-japan-pp-cli ./cmd/activity-japan-pp-cli, add ./bin to PATH, and verify activity-japan-pp-cli --version. The installer below applies to released library packages. Run leaf --help when a flag is unclear.

Prerequisites: Install the CLI

This skill drives the activity-japan-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 activity-japan --cli-only
  2. Verify: activity-japan-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/activity-japan/cmd/activity-japan-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.

Inspect Activity Japan plans and future dates in compact JSON. Compare a bounded shortlist against traveler constraints and carry source uncertainty through booking handoff.

Workflow

  1. Get a plan ID from the traveler or an Activity Japan /publish/plan/<id> URL. If they only give a destination or activity type, use the Activity Japan website to identify IDs; CLI search pages are currently WAF challenged.
  2. Run experience detail ID --lang en --agent. Keep name_original_ja, operator_id, option IDs, meeting point, venue, restrictions, cancellation text, and missing separate. The website locale and locale_support_flag do not establish spoken guide languages.
  3. For an itinerary date, run experience sessions ID --date YYYY-MM-DD --agent, then experience price ID --date YYYY-MM-DD --adults N --agent. Use --option ID to inspect one selected price option. A zero yen child or infant option is not an adult price.
  4. If an exact per-person session needs a stock recheck, pass its current session_id to experience check ID --date YYYY-MM-DD --session ID --adults N --agent. Treat the result as an observation. Group-priced quantity checks are refused because the source count basis is unverified.
  5. For 2–5 known IDs, run experience compare ID ID --date YYYY-MM-DD --adults N --age A --max-jpy B --agent. Use --max-minutes N only for total experience duration; mixed source prose remains unknown. unknown is not a match. A subtotal below a budget remains unknown when mandatory fees are unpriced.
  6. Before handoff, run inventory languages ID --agent and experience handoff ID --lang en --agent. experience brief includes a verified canonical URL when the selected language is indexed; otherwise it marks the URL unresolved.

Done when the answer names the exact plan and option where relevant, source URL, Asia/Tokyo observation time, price unit and age band, dated availability state, and unresolved conditions. Never call an observation a reservation.

Quick commands

bash
activity-japan-pp-cli experience detail 62375 --lang en --agent
activity-japan-pp-cli experience sessions 62375 --date 2026-10-08 --limit 5 --agent
activity-japan-pp-cli experience price 62375 --date 2026-10-08 --adults 2 --option 176511 --agent
activity-japan-pp-cli experience dates 62375 --dates 2026-10-07,2026-10-08 --agent
activity-japan-pp-cli inventory languages 62375 --agent

Replace dates with future dates in Asia/Tokyo. stdout is one JSON object; diagnostics are on stderr. --select reduces fields. Session and price results paginate with --page and --limit; truncation and partial failures are explicit. Plan, price and session reads refresh every run. Language inventory has a 24-hour bounded cache; use --refresh for a new sitemap observation.

The public plan endpoints need no credential. The official partner API requires an NDA and commercial agreement. The CLI makes no booking or payment request.

Do not use for

  • Destination or category search without a known Activity Japan plan ID or URL; use the website to identify plans first.
  • Confirming a reservation, payment, or instructor language; this CLI only reports source observations and explicit unknowns.
  • Experiences on other marketplaces.

Unique Capabilities

These commands assemble source observations for an Activity Japan itinerary.

Itinerary fit
  • experience dates — See observed session and option-price differences across up to seven itinerary dates.

    Use when a traveler can move an activity between nearby dates.

    Use after collecting Activity Japan plan IDs or links.

    bash
    activity-japan-pp-cli experience compare 62375 2044 --date 2026-10-08 --adults 2 --agent
Price clarity
  • experience price — See source option IDs, selected-date amounts, participant basis, and excluded extras.

    Use before comparing activity costs for a specific party.

    bash
    activity-japan-pp-cli experience price 62375 --date 2026-10-08 --adults 2 --option 176511 --agent
Source coverage
  • inventory languages — Check whether a plan ID is indexed in English, Japanese, or both.

    Use before handing an English-language source link to a traveler.

    bash
    activity-japan-pp-cli inventory languages 62375 --agent
Booking handoff
  • experience brief — Get a compact booking-handoff packet with known conditions and unresolved questions.

    Use when the traveler is ready to review the official booking page.

    bash
    activity-japan-pp-cli experience brief 62375 --date 2026-10-08 --adults 2 --lang en --agent
