Date anchor: Today's date comes from the # currentDate system context. Compute ALL relative dates from it. Example: if today = 2026-03-14, then "prior month" = 2026-02-01 to 2026-02-28, "current month" (most recent complete) = February 2026, "three months ago" = December 2025. Never use training-data dates.

get_sold_summary parameter safety:

  • Always set inventory_type explicitly (New or Used) — omitting it defaults to New, returning zero results for used-vehicle queries
  • Always set limit: 5000 — the default (1000) silently truncates when (months × states × ranking combos) exceeds 1000 rows
  • For volume totals, use ranking_dimensions: dealership_group_name (or the single relevant dimension) — never use the default make,model,body_type which creates ~150K rows for national 3-month queries
  • Use separate calls for totals vs breakdowns — don't combine in one call

Geographic Arbitrage Finder — Cross-Market Price Gap Analysis

Profile

Load the marketcheck-profile.md project memory file if exists. Extract: target_dmas, vehicle_segments, country. If missing, ask for at least 2 states to compare. US only — requires get_sold_summary for cross-state pricing. UK: Not available (single market). Confirm: "Using profile: [company], target DMAs: [list]".

User Context

Auction house sales exec or regional director looking for arbitrage — vehicles priced lower in one state that can be transported and auctioned in a higher-price state for profit.
