Return OhMyWind's calculation methodology as Markdown. Call this when the user asks how passage timing, complexity, or boat speed are computed (e.g. "comment c'est calculé ?", "what assumptions does the model use?", "is tacking modelled?"). The returned text covers: polar lookup, default efficiency 0.75, VMG / tacking correction, wave derate, single-pass timing, compare-windows mode semantics, Mediterranean simplifications (tides, current

List Boat Archetypes

List the 7 boat archetypes with descriptive metadata. The LLM (or user) maps a commercial model (e.g. "Sun Odyssey 32") to one of these archetypes from the metadata — there is no server-side mapping.

Get Marine Forecast

Fetch wind (and sea, when available) for a point and time window. Args: lat: latitude in degrees. lon: longitude in degrees. start: ISO-8601 datetime, timezone-aware (e.g. "2026-05-01T06:00:00+00:00"). end: ISO-8601 datetime, timezone-aware. models: optional list of model names; defaults to AROME for the Med. Pass a point at sea. Over land Open-Meteo still returns wind, but every sea value comes back null, so t

Plan Passage

Plan an A→B passage. Compare departure windows by default; pin a single departure only when the user gives an explicit time. ## Tool routing: read this first Before calling, classify the user's question: 1. **Pure weather lookup at a point** ("y aura-t-il du vent à Cassis samedi à 14h ?", "quelles vagues dimanche au cap Sicié ?"): call ``get_marine_forecast`` and answer in text. Do NOT call ``plan_passage``: there's no route to
