What it does

Pp Weathernews is an agent skill from mvanhorn/printing-press-library. Japan weather and seasonal travel evidence with explicit dates, freshness and coverage. Trigger phrases: Japan weather evidence, Kyoto foliage dates, cherry blossom reports, use weathernews, run weathernews.

Its SKILL.md is about 1.5k 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

  • Phrases: Japan weather evidence
  • Kyoto foliage dates
  • Cherry blossom reports
  • Use weathernews

Example prompts

  • “/pp-weathernews”

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: weathernews-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 d9a1696. 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:

    • npx
    • go

    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 Weathernews loads about 1.5k tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 552 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.

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

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.

Weathernews — Printing Press CLI

Prerequisites: Install the CLI

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

Resolve Japanese places, inspect bounded forecasts and seasonal evidence, and compare caller criteria. Public first-party access without a paid account.

When to Use This CLI

Resolve Japanese weather places, check bounded forecasts, inspect cherry blossom or autumn foliage evidence, or compare explicit caller thresholds. All data comes from Weathernews public first-party pages.

Anti-triggers

Use another workflow for bookings, purchases, universal destination ratings, other providers, commercial WxTech, or member-only radar. See README coverage before interpreting mountain-place coordinates as summit evidence.

Unique Capabilities

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

Command Reference

Read weathernews-pp-cli places --help, weathernews-pp-cli weather --help and weathernews-pp-cli season --help for live flag truth. Resolve names before choosing coordinates; search each seasonal product before selecting its spot IDs.

Recipes

bash
weathernews-pp-cli season search --product koyo --area kyoto --agent --select items.id,items.name_ja,season

Find source IDs before lazy details

Auth Setup

Selected public products need no credentials. Member-only products and commercial WxTech are outside scope.

Run weathernews-pp-cli doctor to verify setup.

Agent Mode

Focused commands emit compact JSON. --agent adds meta/results; --select projects dotted paths through arrays. Retain season/source/horizon when answering freshness questions. Metrics/errors are stderr. Keep issue time null when missing; never substitute fetch time or first valid time. Separate observation, forecast and historical norm; infer date year only from the source season title. Elevation stays null if absent.

Paths and state

Use --home /absolute/path for isolated config/state/cache, and --no-learn for deterministic read-only tasks. Focused caches have bounded TTL and no stale fallback. --refresh explicitly refreshes inventory; --data-source local serves only fresh cached source snapshots. Paginate with next_offset before refreshing; spot details are lazy.

Health Check

Run weathernews-pp-cli doctor --dry-run locally; places resolve --query 京都 --metrics checks live public access.

Troubleshooting

Check stderr and exit code: 2 usage/projection, 3 not-found/cache miss, 4 access restriction, 5 upstream/schema/partial comparison, 7 rate limit, 10 local path/config. An empty search is valid. Partial comparisons emit candidate errors plus exit 5. See README and evidence/final-report.md for current seasonal coverage and live verification.
