Forecast peak autumn-foliage dates for viewing spots across Japan. Free tier, no key.
Scored across 4 tools
Each tool has a distinct role: get_coverage for scope, search for free-text lookup, find_peak_spots for date/location queries, and fetch for detail by id. There is some overlap between search and find_peak_spots and between find_peak_spots and fetch, but the descriptions are specific enough to route correctly.
All names are lowercase imperative verbs, which provides a consistent style, but fetch and search are bare verbs while find_peak_spots and get_coverage use verb_noun construction. This is a minor structural inconsistency rather than a chaotic mix.
With four tools covering one narrow forecast domain, the set is appropriately scoped. No tool feels extraneous, and there are enough tools to answer the main forecast questions without overwhelming the agent.
The surface covers orientation via get_coverage, discovery by text or date/location via search and find_peak_spots, and full detail retrieval via fetch. For a read-only forecast server this is complete; no obvious missing operation blocks a typical query workflow.
Fetch the full forecast document for one foliage spot by id (the slug returned by search or find_peak_spots, e.g. 'tenryuji-temple'): peak window, confidence, status, nearest rail station, leaf type, and page URL.
Inputs: id (required).
Find Japan autumn-foliage viewing spots whose forecast best-viewing window covers a date or date range, optionally near a place. Use it for 'where should I go on ?', 'when does peak?', and 'is still at peak on ?' questions. Give a date (or date_from/date_to) plus optionally a location: near (city or prefecture name, e.g. 'Kyoto') or lat/lon, with radius_km; or restrict by region or prefecture. Returns each spot's forecast peak window (start–end), confidence in days, nearest rail station, leaf type, and a page URL, sorted by prominence then proximity. Example prompts: 'Which foliage spots near Kyoto peak on 20 November?', 'Best koyo in Tohoku the first week of November', 'Is Nikko past peak by 1 December?'. Example call: {date: '2026-11-20', near: 'Kyoto', radius_km: 60}.
Inputs: lat, lon, date, near, +7 more.
Describe what the RoamTime Japan autumn-foliage (koyo) forecast covers: forecast year and issue date, season span, regions and prefectures, spot count, and the access tier (free tier or full dataset). Call this first to orient yourself, to check whether a place or date is in scope, and to learn the as_of date to cite. Takes no arguments. Example prompts: 'What does the RoamTime foliage forecast cover?', 'Is Hokkaido included?'
Inputs: no named parameters.
Search Japan autumn-foliage viewing spots by free text: a spot name (English or Japanese), a prefecture, a region, or a month such as 'November'. Returns matching spot ids, titles, and page URLs; pass an id to fetch for the full forecast. Example queries: 'Kyoto', 'Nikko', '奥入瀬', 'Tohoku November'.
Inputs: query (required).
