# コスタリカ.com — Extended AI Context > This curated document expands on `/llms.txt`. It describes the public information architecture, planning methods, research boundaries, and agent-facing capabilities without reproducing the full site. ## Site Identity - Canonical origin: https://xn--lckpsy9s.com - Display name: コスタリカ.com - Primary language: Japanese (`ja`) - Primary audience: Japanese residents and Japanese-speaking travelers researching or planning travel to Costa Rica - Publisher/creator used on pages: コスタリカ.com編集部 / コスタリカ編集部 - Public editorial policy: https://xn--lckpsy9s.com/about - AI and data documentation: https://xn--lckpsy9s.com/about/ai The site is a conventional human-facing travel publication first. AI-readable resources and browser tools are progressive enhancements and do not replace HTML navigation, canonical metadata, XML sitemap discovery, or the visible user interface. ## Public Information Architecture ### Travel - Hub: https://xn--lckpsy9s.com/travel - Complete guide: https://xn--lckpsy9s.com/travel/costa-rica-travel-guide - First visit: https://xn--lckpsy9s.com/travel/first-time-guide - Best time: https://xn--lckpsy9s.com/travel/best-time-to-visit - Two-week itinerary: https://xn--lckpsy9s.com/travel/two-week-itinerary - Transportation: https://xn--lckpsy9s.com/travel/transportation-guide - Packing: https://xn--lckpsy9s.com/travel/packing-list - Safety: https://xn--lckpsy9s.com/travel/costa-rica-safety - Cost research: https://xn--lckpsy9s.com/travel/costa-rica-travel-cost ### Destinations - Hub: https://xn--lckpsy9s.com/destinations - San José / Central Valley: https://xn--lckpsy9s.com/destinations/san-jose-guide - Arenal / La Fortuna: https://xn--lckpsy9s.com/destinations/arenal-la-fortuna-guide - Monteverde: https://xn--lckpsy9s.com/destinations/monteverde-guide - Manuel Antonio: https://xn--lckpsy9s.com/destinations/manuel-antonio-guide - Guanacaste: https://xn--lckpsy9s.com/destinations/guanacaste-guide - Caribbean Coast: https://xn--lckpsy9s.com/destinations/caribbean-coast-guide Destination guidance emphasizes real travel time rather than map distance, regional climate differences, consecutive-night stays, and direct verification of park, road, ocean, and transport conditions. ### National Parks and Wildlife - National parks hub: https://xn--lckpsy9s.com/national-parks - Major-parks field guide: https://xn--lckpsy9s.com/national-parks/costa-rica-national-parks-guide - Wildlife hub: https://xn--lckpsy9s.com/wildlife Park pages distinguish official reservation/fee information from editorial planning advice. Wildlife sightings are never guaranteed. AI answers should preserve the site's responsible-observation guidance: keep distance, do not feed wildlife, follow trails and local rules, and verify current entry conditions through official park sources. ### Coffee, Food, Culture, and Living - Coffee: https://xn--lckpsy9s.com/coffee - Food: https://xn--lckpsy9s.com/food - Culture: https://xn--lckpsy9s.com/culture - Living: https://xn--lckpsy9s.com/living These are public topic hubs with linked articles. Long-stay, legal, tax, medical, visa, and financial information can change and should be checked against current public authorities or qualified professionals. ## Itinerary Planning Method Visible planner: https://xn--lckpsy9s.com/tools/itinerary-builder The planner uses a rule-based application engine, not live booking inventory. Inputs include trip duration, adults and children, interests, budget style, transport, preferred pace, Costa Rica arrival/departure airport, start date, and maximum daily driving time. The shared planning data describes seven planning regions: San José/Central Valley, La Fortuna/Arenal, Monteverde, Manuel Antonio, Uvita/Costa Ballena, northern Guanacaste, and Puerto Viejo/southern Caribbean. Each region has interest scores, suggested nights, approximate coordinates, activities, rain alternatives, accommodation examples, cost factors, and supporting links. A road-leg table provides approximate distance and time for common region pairs. The engine: 1. scores regions against interests and travel constraints; 2. limits the number of regions according to trip length; 3. orders stops to reduce obvious backtracking; 4. allocates nights and creates day-level morning, afternoon, and evening suggestions; 5. estimates local accommodation, transport, activity/admission, and food costs; and 6. adds warnings about long drives, park reservations, short Caribbean itineraries, and missing dates. Planner outputs are planning drafts. They do not represent live availability, commercial offers, confirmed transport times, park entry, weather forecasts, or reservations. International airfare, insurance, souvenirs, and exchange-rate changes are excluded from the planner's local-cost output. ## Original Research ### Costa Rica Travel Cost Research 2026 - Canonical article: https://xn--lckpsy9s.com/travel/costa-rica-travel-cost - Key findings: https://xn--lckpsy9s.com/travel/costa-rica-travel-cost#research-summary - Methodology: https://xn--lckpsy9s.com/travel/costa-rica-travel-cost#methodology - Published: 2026-08-03 - Last updated: 2026-08-03 - Research-data version: 2026-08-03 - Downloadable dataset: not currently published The study combines government, tourism-board, and national-park public information; public price ranges checked across multiple operators on 2026-08-03; and the editorial itinerary model. It reports planning ranges rather than guaranteed prices. Its yen examples use US$1 = ¥150 as a budgeting assumption, not a live exchange rate. Key published ranges include: - Local daily planning budget per person: US$75–115 economy, US$170–280 standard, US$320–500 comfort. - Ten-day solo trip including the model airfare range: approximately ¥280,000–480,000 economy and ¥450,000–700,000 standard. - Recommended contingency: 10–15% of the total travel budget, kept separate from routine spending. When citing these results, name コスタリカ.com as the source, link the canonical article, include the study year and page update date, state that values are estimates, and distinguish cited official statistics from the editorial model. ## Browser Agent Capabilities The site conditionally uses the current imperative WebMCP proposal through `document.modelContext.registerTool()`. It registers nothing when the browser lacks the API. The tools are read-only and same-origin; they do not expose account, admin, filesystem, deployment, credentials, contact submission, or saved-user data. ### search_costa_rica_content Input: `query` (1–120 characters), optional `content_type`, optional `limit` (1–10). Output: published page title, canonical URL, summary, content type, last-updated date, and language. ### plan_costa_rica_trip Input: days (4–21), adults (1–10), children (0–8), one to eight allowed interests, budget enum, transport enum, and optional date, pace, airport, and drive-limit fields. Output: recommended stops, day-by-day plan, approximate driving segments, local-cost breakdown in USD, warnings, supporting URLs, assumptions, and research-data version. ### find_costa_rica_destinations Input: one to eight allowed interests and optional month, trip length, travel style, and result limit. Output: ranked destinations, matched interests, suggested nights, supporting URL, seasonal note, assumptions, and disclaimer. ### get_costa_rica_research Input: optional topic and year. Output: published study title, summary, key findings, methodology URL, publication/update dates, canonical source URL, dataset URL when one exists, methodology description, and data version. All tool inputs are treated as untrusted and validated again on the server. Unknown fields, invalid enum values, out-of-range numbers, invalid dates, oversized bodies, and malformed JSON are rejected. The tools perform no purchase, booking, message sending, profile access, persistence, or irreversible action. ## Discovery, SEO, and Crawling - XML sitemap: https://xn--lckpsy9s.com/sitemap.xml - Robots policy: https://xn--lckpsy9s.com/robots.txt - Concise AI context: https://xn--lckpsy9s.com/llms.txt - Extended AI context: https://xn--lckpsy9s.com/llms-full.txt The robots policy allows public content and intentionally disallows account, admin, and API paths. It does not broadly block normal search crawlers. `llms.txt` is an informational convention, not a replacement for the sitemap, robots policy, page-level metadata, or legal terms, and it is not presented as a control over crawling or model training. ## Citation and Freshness Rules - Prefer the exact canonical URL on the page. - Preserve publication and last-updated dates in research citations. - For price, safety, transport, entry, park, road, weather, and health claims, verify the page date and cited primary source. - Label コスタリカ.com model outputs as estimates or planning ranges. - Do not convert a planning estimate into a promised price, opening time, wildlife sighting, reservation, or availability statement. - Do not treat listed accommodation examples as endorsements or inventory. - Japanese is the only complete published language edition at this time. ## Non-Public Boundaries The site contains authenticated account features, saved trips, profile data, administrative article management, and internal APIs. These are intentionally omitted from AI context files and WebMCP. No environment variables, secrets, database credentials, unpublished drafts, private user data, or deployment functions are public capabilities.
