Jeffrey (Dongkyu) Kim 397d0eea84 Expose official nearby fuel prices for location-based gas station lookups ... Add the first cheap-gas-nearby skill/package pair so nearby gas-price queries can resolve a user-supplied location, translate it into Opinet's KATEC search contract, and return the cheapest nearby stations with address and facility detail. The docs and setup surfaces now advertise the new skill and its Opinet API key requirement. Constraint: Nearby fuel prices must come from the official KNOC Opinet API when available Constraint: No new external dependencies were allowed for coordinate conversion or location resolution Rejected: Map-only gas price scraping | official Opinet Open API exists and is the preferred source Rejected: Require lat/lng input only | poorer UX than supporting landmark/station queries through anchor resolution Confidence: medium Scope-risk: moderate Reversibility: clean Directive: Keep `OPINET_API_KEY` as the only supported official-price credential unless the repo adopts an Opinet proxy later Tested: npm run ci; node --test packages/cheap-gas-nearby/test/index.test.js; offline fixture smoke via searchCheapGasStationsByLocationQuery('서울역', ...) Not-tested: Live Opinet API call with a real `OPINET_API_KEY` (no non-placeholder key was configured locally) Related: #54		2026-04-05 19:46:09 +09:00
