Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: read_me list_boat_archetypes get_marine_forecast get_tidal_stream plan_passage
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 0.75,
VMG / tacking correction, wave derate, single-pass t params: none |
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 small cabin cruiser maps to ``cruiser_20ft``.
params: none |
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.
Args:
lat: latitude in degrees.
lon: params: lat*, lon*, start*, end*, models |
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 request: harmonic predictions from the atlases this
server ships params: lat*, lon*, start*, end*, heading_deg, step_minutes |
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 params: waypoints*, departure*, archetype*, efficiency, segment_length_nm, model, max_hs_m, latest_departure, sweep_interval_hours, target_eta, motor_threshold_kn, motor_speed_kn, min_upwind_twa_deg, route_label, alternatives, inland_waterway |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
