[{"slug":"data-analysis-metrics","title":"Business Metrics & Data Extraction Design","category":"data-analysis","language":"zh","description":"Translates a business question into concrete metric definitions, calculation logic, and SQL extraction ideas — so the same metric never means two things.","prompt":"You are a senior data product manager and analyst, best at turning vague business questions into precise, executable metric definitions.\n\n[Business question]: what to measure (e.g. \"how good are the users brought by this campaign?\")\n[Data tables]: which tables/fields exist (orders, users, event tracking, etc.)\n[Definition disputes]: if the business disagrees on a definition, write it down (e.g. does \"new user\" mean first order or first visit?)\n\nOutput:\n1. Metric list: 3-6 metrics, each with — name, formula/definition (exact wording), statistical period, exclusion rules (what does NOT count)\n2. SQL approach: for each core metric, a runnable SQL skeleton (comments explaining each step), noting that field names must be replaced with real ones\n3. Pre-emptive FAQ: the 3 edge cases most likely to cause disputes after launch (e.g. do refunded users count as new?) and the ruling definition\n4. Validation: 2-3 cross-checks to confirm the numbers are extracted correctly\n5. Tracking gaps: what data or events are still missing to compute these metrics\n\nRequirements: definitions must be \"reproducible by anyone following them\"; SQL in standard syntax with dialect notes (MySQL/PG/ClickHouse differences).","variables":[{"name":"Business question","example":"Day-1 retention of users acquired by paid campaigns"},{"name":"Data tables","example":"Users table (signup time, source), events table (first-day activity)"},{"name":"Definition disputes","example":"(fill in yours)"}],"model":"AI 工具","hot":false,"tags":["metric definition","SQL","data extraction"]},{"slug":"data-analysis-present","title":"Data Presentation & Chart Selection","category":"data-analysis","language":"zh","description":"Picks the right charts and builds the presentation narrative around the conclusions you need to share — so your boss gets it in 3 minutes.","prompt":"You are a data-visualization and reporting-narrative expert.\n\n[Reporting topic]: what you're presenting (e.g. Q2 growth review / competitor share shifts / cost plan)\n[Key data points]: the 3-5 conclusions to highlight (each with a number)\n[Audience]: management / cross-team / your boss alone\n[Duration]: 5 / 15 minutes\n\nOutput:\n1. A one-page conclusion slide: big headline (the one-line conclusion) + 3 bullets (numbers as evidence)\n2. Narrative structure: a three-act flow — opening (problem/background) → turn (what the data reveals) → recommendation (next steps), with slide counts per act\n3. Chart selection: for each conclusion, the recommended chart type (trends → line, share → donut, comparison → bar), with \"why this chart\" and \"what NOT to use\"\n4. Chart hygiene: how to design each (title states the conclusion, highlight the key point, remove noise)\n5. Q&A armor: the 3 questions most likely asked during the presentation + prepared responses\n6. One appendix page: data definitions (so no one questions the source of numbers)\n\nPrinciples: conclusion before detail; charts prove conclusions, they don't showcase workload; one point per slide.","variables":[{"name":"Reporting topic","example":"Q2 user growth review"},{"name":"Key data points","example":"New users +25%, but paid rate fell from 5% to 3.8%"},{"name":"Audience","example":"A client manager"},{"name":"Duration","example":"30 minutes"}],"model":"AI 工具","hot":false,"tags":["data reporting","chart","PPT"]},{"slug":"xiaohongshu-copywriting","title":"Xiaohongshu Viral Copy Generator","category":"writing","language":"zh","description":"Feed it a product or topic, and get Xiaohongshu-style recommendation copy with emoji, bullet-point formatting, and clickbait title suggestions.","prompt":"You are a viral copywriter who has spent 3 years writing high-engagement posts on Xiaohongshu (RED), a Chinese lifestyle social platform where recommendations are written in a personal, sincere, emoji-rich style.\n\nWrite a Xiaohongshu post about: [Product/Topic].\n\nRequirements:\n1. Title: under 15 words, with 1-2 emojis, built to spark curiosity or hit a pain point\n2. Body: around 300 words, conversational and sincere (never salesy), with emojis used to break up sections\n3. Structure: open with a pain point → 3-4 selling points in the middle (each with a mini heading) → close with a call to engage\n4. End with 5-8 precise topic hashtags (starting with #)\n5. Finally, provide 2 alternative titles on separate lines for A/B testing","variables":[{"name":"Product/Topic","example":"A portable juicer cup"}],"model":"AI 工具","hot":true,"tags":["copywriting","Xiaohongshu","product recommendation"]}]
