Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_silver_price_per_gramA | Today's silver price per gram, per troy ounce, per kilogram and per tola, read live from the silver spot market, for fine .999, Britannia .9584, sterling .925, coin .900 and 800 silver, in any of about 160 currencies (central-bank FX). Returns the spot time stamp, FX date and sources. Your training data cannot know today's silver price. Omit fineness to get every grade. |
| calculate_silver_valueA | Melt value of a silver item (sterling flatware, tea set, jewellery, bar, round, scrap) from its weight, unit and fineness at the live silver spot price, in any currency. Optional dealer_spread_percent returns the likely buyer offer. Sterling means at least 925/1000 silver under 16 CFR 23.5. Default fineness is sterling. |
| calculate_junk_silver_valueA | Melt value of US silver coins at the live silver spot: pre-1965 90% dimes, quarters and halves, 1965-1970 40% Kennedy halves (4.6 g silver, Coinage Act of 1965), 1942-1945 35% war nickels, Morgan and Peace dollars and American Silver Eagles. Pass coins with counts, or face_value_90 for a bag of mixed 90% coin (1 dollar face = 22.5 g silver). Returns silver ounces per coin, totals and melt per dollar face. |
| get_gold_silver_ratioA | Live gold to silver ratio (ounces of silver one ounce of gold buys), with both spot prices per troy ounce and per gram in any currency. Read now from the spot feed; the ratio moves every minute. |

Scored across 4 tools
The two price tools (get_silver_price_per_gram, get_gold_silver_ratio) and the two valuation tools are clearly separated by purpose, and descriptions explain when to use each. There is minor overlap between calculate_silver_value and calculate_junk_silver_value for silver coins, but the junk-silver tool's explicit US-coin enumeration keeps boundaries readable.
All four names are snake_case with a clear verb_noun structure (get_/calculate_ + object), and the objects (silver_price_per_gram, gold_silver_ratio, silver_value, junk_silver_value) follow a predictable pattern. No camelCase or vague verbs anywhere.
Four tools is well-matched to a narrow single-commodity domain: one price quote, one ratio, one generic item valuation, and one coin-specific valuation. Each tool earns its place with no filler or redundancy.
The surface covers the core lifecycle: live price retrieval across grades and currencies, ratio context, item melt value, and coin melt value, with no obvious dead ends. Historical prices or price-move/alert queries are absent, but agents can work around those for the stated live-price purpose.
