poketrace-api-expert 是做什麼的？
Use any time Claude Code works with the PokeTrace API in this project — editing server.js's pokeTraceFetch/resolvePokeTraceCard/lookupCardPrices, src/api/poketrace.js, the /api/prices, /api/price-history, or /api/listings routes, the price_snapshots table, or anything involving card price lookups, price history, grading tiers, set-slug/card-number matching, or PokeTrace rate limits and plan tiers. Also use when asked what PokeTrace's API can do, whether an endpoint/param exists, or how to add a new PokeTrace-backed feature (sets browsing, graded prices, websocket live updates, sold-listing comps, non-English cards).
