See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> JMA source workflow Prerequisites: Install the CLI This skill drives the jma-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: 2. Verify: jma-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: 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. 1. Resolve the destination with jma-pp-cli areas search --query Kyoto --kind municipality, then areas resolve --area 2610000. Use the returned source ID; exact name ambiguity is an error. Stations are forecast temperature references; use stations search for a station request. 2. Read forecast get --area 130010 --period all --days 3. Preserve district/station IDs, issued and valid times, units, source confidence and missing null values. Short extrema time markers are not instantaneous temperatures. 3. Read warnings get --area 1310100. Summaries cover all resolved municipalities before pagination. Report source Japanese wording and lifecycle; inspect --detail for source hazard properties. nonereported concerns retrieved municipality weather products only. …
