Tools it offers

32 tools, as the server itself reported during our check on Oct 31, 2026.

• query_plantingsList the user's plantings (what is planted, where, when, how, current status). Use when the user asks what they planted, when something was sown/transplanted, or what's growing in a bed.
• search_eventsSearch the garden log: watering, fertilizing, transplanting, pruning, pest sightings, treatments, frost damage, notes. Use when the user asks when they last did something or what happened in the garden.
• get_harvestsList harvests with per-plant totals. Use when the user asks what/how much they harvested.
• list_bedsList the garden's beds: name, type (outdoor_bed/raised_bed/greenhouse/grow_light_shelf/pot), dimensions in cm, notes, and how many active plantings each holds. Use to see what beds exist and where there may be room.
• get_bed_layoutRead a bed's layout grid: the bed's dimensions (cm) plus each placed planting's footprint (xCm, yCm from the bed's top-left; wCm × hCm), and any active plantings not yet placed. Use to reason about space — e.g. "is there
• get_current_conditionsCurrent weather at the garden (station if connected, else forecast) plus per-bed soil moisture/temperature. Use for "how is the garden right now / should I water".
• get_soil_readingsLatest soil moisture % and soil temperature per bed, with bed names. Use for watering/sowing decisions.
• get_forecast7-day forecast for the garden with overnight-low frost alerts. Use for planting timing, frost protection, watering plans.
• get_historyDaily weather history for the garden: min/max temp, rain, growing degree days (base 10 °C) with a cumulative total. Use for "how warm/wet has it been" and growth-progress questions.
• get_planUpcoming sowing/transplant windows computed from the user's plant catalog and the garden's frost dates, plus zone, frost dates, and any due care tasks (watering/fertilizing, with a rain-skip hint). Use for "what should I
• log_eventRecord something the user did or observed: watered, fertilized, transplanted, pruned, pest sighting, treatment, frost damage, or a note. Attach it to a plant's active planting via `plant`, to a bed via `bed`, or garden-w
• record_harvestRecord a harvest, e.g. "I picked 2 kg of cucumbers" or "2 lb of tomatoes". Resolves the plant's active planting automatically. Pounds and ounces are stored as grams.
• add_plantingRecord that the user planted/sowed something: creates the plant in their catalog if new and the planting in the named bed. Passing variety replaces the variety stored on an existing plant with the same name.
• log_curingRecord that a harvested crop has finished curing (or dismiss the reminder). Use when the gardener says they've cured, dried, trimmed or stored a crop like garlic, onions or herbs.
• create_bedAdd a garden bed. `type` is one of outdoor_bed (in-ground), raised_bed, greenhouse, grow_light_shelf, pot. Dimensions (lengthCm/widthCm/heightCm) are optional. Use when the user wants a new bed or planting area.
• update_bedChange an existing bed's name, type, or dimensions. Identify the bed by its current name. Use when the user wants to rename a bed, change its type, or set/adjust its dimensions.
• set_care_scheduleCreate a recurring care schedule (water/fertilize/custom). Scope it to a plant (its active planting), a bed, or the whole garden. Recurrence is EITHER everyDays (e.g. 3) OR weekdays (e.g. ['monday','thursday']). Use when
• update_plantingChange a planting's status (active/finished/failed), notes, quantity, transplant date, variety, or MOVE it to another bed (pass bed with the target bed's name — history stays attached; any layout position is cleared, re-
• delete_plantingRemove a planting from the garden. Siltwell archives it: it disappears from the app and from these tools, and its care schedules stop. Its harvests, events and photos stay stored, but the app has no way to restore it. Id
• delete_bedRemove a bed from the garden. Siltwell archives it: it leaves the bed lists in the app and in these tools, its care schedules stop, and planned plantings queued for it are skipped. Past weather history still shows its na
• delete_scheduleTurn off a recurring care schedule (stops its reminders). Identify it by scheduleId, or by scope — plant (its active planting), bed, or garden-wide (neither) — optionally narrowed by type (water/fertilize/custom). Use wh
• update_harvestCorrect a logged harvest — the most-recent harvest of a plant (by name) or a specific harvestId. Edit quantity, unit, notes, or the date. Use when the user says a harvest they recorded was wrong.
• place_plantingPlace or move a planting on its bed's layout grid — set its position (xCm, yCm measured from the bed's top-left corner) and footprint (wCm × hCm) in centimeters. Identify the planting by plant name or plantingId. Use whe
• list_planned_plantingsList the garden's succession plan — future plantings queued for a bed that haven't been sown yet (only status='planned'; done/skipped entries are omitted). Use when the user asks what's coming up next, what they've plann
• add_planned_plantingQueue a future planting for a bed as part of a succession plan — it is NOT yet sown (use add_planting for something the user already planted). Use when the user wants to plan ahead, e.g. "plan to plant more carrots in Be
• update_planned_plantingUpdate a queued succession-plan entry: change its status (planned/done/skipped), reschedule its targetDate, or adjust quantity/notes. Identify it by id (from list_planned_plantings). Use when the user sows a planned plan
• delete_planned_plantingRemove an entry from the succession plan outright (a queued future planting that hasn't been sown). This is a hard delete, not recoverable — for a planting already sown/growing, use delete_planting instead. Identify it b
• get_season_planCompute the garden's rest-of-season planting schedule: every bed's next crops, chained forward to the effective first frost, deconflicted across beds with crop rotation and curated sow windows. Returns a PROPOSAL only —
• lookup_frost_datesAverage last spring frost, average first fall frost and hardiness zone for any place, from 10 years of weather records. Works without a Siltwell account. Dates are MM-DD. For the signed-in user's own garden, get_plan ret
• lookup_planting_windowsWhen to start seeds indoors, plant out, and sow for a fall harvest at any place, crop by crop, with the days left to sow today. Works without a Siltwell account. Dates are YYYY-MM-DD. Without crops, it returns the 30 cro
• lookup_growing_seasonFrost-free season length and seasonal growing degree days at any place, and whether heat-loving crops get enough heat to ripen. Works without a Siltwell account. For the signed-in user's own garden, get_plan returns the
• lookup_frost_riskForecast lows for the next 7 days at any place and the nights at risk of frost. Each frost night is dated by the morning its low falls on, so protect plants the evening before that date. Works without a Siltwell account.
