- src/tools/hotNews.ts:130-179 (handler)Core handler logic: validates limit, fetches raw news from Tushare API, deduplicates using 80% Jaccard similarity on title+summary bigrams, formats as markdown list with source/day stats, handles errors and empty results.async run(_args?: { limit?: number }) { try { const logs: string[] = []; const rawLimit = typeof _args?.limit === 'number' && isFinite(_args.limit) ?
