## Tools (as reported by the server, not verified)

- `read\_me`: 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
- `list\_boat\_archetypes`: List the 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. \`\`voile\_aviron\_16ft\`\` is for open sail-and-oar dinghies only \(no cabin, rowed as well as sailed\); a sm
- `get\_marine\_forecast`: Wind, sea, and where it matters current and tide, at one point. For the questions about a place rather than a passage: how hard it blows at Groix this afternoon, when the thermal breeze fills in, when the mistral eases, whether the models agree, what the swell does at a harbour entrance tonight. Arg
- `get\_tidal\_stream`: The tidal stream and the tide at one point, from the tidal atlases alone. For the questions about a pass or a harbour entrance: when to be at the Raz de Sein to carry the stream, when the Fromveur turns, how hard it runs at Port-Navalo tomorrow, when high water is at Chausey. Costs no weather reques
- `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 v
