圖表深潛分析

對特定的 Amplitude 圖表進行深度分析,以解釋趨勢、異常及可能的驅動因素。當指標看起來異常、需要調查突然上升或下降的原因,或想了解數據背後的「為什麼」時使用。

圖表深潛分析 是什麼?

這個技能旨在幫助開發者與數據分析師深入分析 Amplitude 圖表中的趨勢、異常與驅動因素。它支援所有類型的 Amplitude 圖表(如時間序列、漏斗圖、留存率等),並引導使用者從辨識圖表、驗證數據、發現模式,到透過引導式區隔分析與上下文關聯(實驗、部署、客戶反饋)來找出根本原因。最後,它會產出一個結構化、可供決策的分析報告,包含發生事件、時間範圍、主要假設、支持證據、替代解釋與量化影響。此技能特別適合在指標突然上升或下降、需要向利害關係人提交證據導向的分析時使用,並遵循最佳實務(如比較基準期、區分觀察與假設、避免過度切片)。

圖表深潛分析 是做什麼的?

使用時機

  • 指標意外地暴漲或暴跌
  • 你需要了解什麼因素驅動了某個趨勢
  • 準備一份詳細、以證據為基礎的分析給利害關係人
  • 調查不同使用者或事件區隔之間的差異

操作步驟

步驟 0:識別圖表

  • 接受一個圖表 URL 或圖表 ID
  • 如果使用者提供 URL,請使用 Amplitude:getting_data_from_url 來提取圖表 ID
  • 如果沒有提供圖表識別符,請明確要求圖表 URL 或 ID,然後停止

步驟 1:取得並驗證圖表數據(必要步驟)

  • 使用 讀取圖表數據 來取得圖表定義與數據
  • 如果無法取得圖表數據或數據為空,請勿繼續
    • 說明缺少哪些內容(時間範圍、事件、篩選條件、權限)
    • 要求使用者修正圖表或提供有效的圖表

擷取並重新說明:

  • 正在衡量的指標
  • 時間範圍與粒度
  • 圖表類型(例如時間序列、漏斗圖、留存率)
  • 現有的篩選條件、區隔或分群

步驟 2:識別模式與變化窗口

使用 圖表分析 來描述正在發生的事情:

  • 暴漲 / 暴跌:特定日期出現的突然變化
  • 趨勢:隨時間逐漸增加的趨勢或逐漸減少的趨勢
  • 季節性:每週或每月重複出現的模式
  • 異常:偏離近期基準或歷史行為的現象

明確指出:

  • 變化窗口(開始/結束)
  • 變化的方向與幅度
  • 用於比較的基準期(預設為前一個相等長度的期間)

步驟 3:調查可能的驅動因素(有限範圍)

不要進行廣泛的切片,而是使用 引導式區隔分析:

  1. 使用 尋找正確的事件屬性 來識別對解釋變化最有相關性的屬性
  2. 選擇 最多 9 個高信號屬性(例如平台、國家、方案、版本)
  3. 帶入這些屬性重新執行 圖表分析,以確定:
    • 哪些區隔對變化貢獻最大
    • 模式是局部性的還是廣泛性的
    • 使用 Amplitude:query_charts 時,一次最多僅獲取 3 張圖表

除非使用者明確要求深入探索,否則避免總共測試超過 9 個屬性。


步驟 4:與上下文關聯(異常時必要)

對於暴漲、暴跌或意外轉變,請收集相同時間範圍內的上下文信號:

  • 使用 取得實驗 來識別正在進行的實驗或功能開關
  • 使用 取得部署 來識別版本發佈或回滾
  • 使用 搜尋內容 來找出註解或相關文件
  • 使用 Amplitude:get_feedback_instights 來搜尋客戶反饋趨勢,這些趨勢可能解釋變化
  • 使用 Amplitude:get_feedback_mentions 來提取特定的客戶提及,如果存在可能與被解釋的變化相關的反饋趨勢

確定是否有任何上下文變化在時間上與圖表模式一致。


步驟 5:綜合分析結果

提供一份結構化、可供決策的分析報告:

  1. 發生了什麼
    對觀測到的模式與幅度進行清晰描述

  2. 何時發生
    確切的時間範圍與比較基準

  3. 主要假設
    基於圖表數據與上下文信號的最可能解釋

  4. 支持證據

    • 關鍵指標
    • 區隔貢獻
    • 相關的實驗、部署或註解
  5. 替代解釋
    1–3 個合理的替代方案,以及它們為何較不可能

  6. 影響
    盡可能量化影響(使用者、事件、轉換、營收代理指標)

  7. 建議的下一步
    一個明確的後續行動(例如深入區隔、審查實驗、檢查埋點)

務必包含:

  • 圖表名稱
  • 圖表 ID
  • 圖表的連結
  • 涵蓋範圍(例如測試過的屬性、分析過的區隔)

最佳實務

  • 務必與明確的基準期進行比較
  • 區分 觀察結果 與 假設
  • 優先使用高信號區隔,而非窮舉式切片
  • 注意數據品質問題(資料量少、期間不完整、大量「(none)」值)
  • 除非使用者明確要求,否則不要建立或編輯圖表

Individual skills in this repo

amplitude/builder-skills

Deeply analyze Amplitude dashboards by analyzing key charts, surfacing top areas for concern and takeaways, identify anomalies, then explain changes using customer feedback trends.

amplitude/builder-skills

Designs A/B tests with proper metrics and variants, analyzes running or completed experiments, and interprets results with statistical rigor. Use when setting up experiments, checking experiment status, analyzing results, or making ship decisions.

Synthesizes customer feedback into actionable themes including feature requests, bugs, pain points, and praise. Use when planning product roadmap, understanding user sentiment, investigating specific issues, or preparing voice-of-customer reports.

amplitude/builder-skills

Analyze MCP server usage instrumented with Amplitude's MCP Analytics SDK: break usage and errors down by tool, read the rationales within each tool to see what callers are trying to do, and produce a prioritized write-up of actionable fixes. Use this skill whenever the user asks to understand how their MCP server is being used, what agents/users are trying to do with it, why tool calls are failing, what to fix or improve in their MCP server, or asks for an "MCP usage report", "tool error analysis", "intent analysis", "rationale clustering", or "MCP insights". Also trigger when the user mentions [MCP]-prefixed events, tool rationale, tool call errors, or just finished instrumenting their MCP server and wants to see what the data says. Requires the Amplitude MCP connector.

amplitude/builder-skills

Read lost deals and churned accounts from your CRM, extract reasons clustered by theme (missing features, pricing, competitors, UX), and write a prioritized weekly analysis with product improvement recommendations. Use before roadmap planning or to build the case for prioritizing retention work.

amplitude/builder-skills

Creates Amplitude charts from natural language descriptions, handling event selection, filters, groupings, and visualization choices. Use when you know what you want to measure but prefer not to build the chart manually.

amplitude/builder-skills

Guide an Amplitude user through building a custom agent by suggesting use cases grounded in their role and data, shaping the idea into a well-formed spec, and generating a ready-to-run Global Agent deeplink that creates it. Use to create, build, or set up a custom agent, automate a recurring analysis, or put a repeated report on a schedule.

amplitude/builder-skills

Builds comprehensive Amplitude dashboards from requirements or goals, organizing charts into logical sections with appropriate layouts. Use when creating a complete dashboard from scratch or assembling existing charts into a cohesive view.

amplitude/builder-skills

Monitors all active and recently completed experiments across Amplitude projects, triages them by importance, then runs deep analysis and reporting on the most impactful ones. Use when the user asks to "check on experiments", "experiment status", "experiment review", "what experiments are running", or wants a periodic experiment health report.

amplitude/builder-skills

Pull Intercom tickets and Slack support messages from the past 7 days, classify each signal, enrich with CRM data (ARR, plan, renewal), score by customer value and churn risk, and output a tiered priority report saved to Drive. Use when you need a fast, data-driven view of what support signals matter most.

amplitude/builder-skills

Use this skill whenever a user wants to improve existing pages on their website to get cited more by AI models — whether they say "our pages aren't getting cited", "improve this page for AI visibility", "which of our pages should we update", "make this article more cite-worthy", "our competitors are getting cited instead of us", "update our content for AI search", or any variation where the goal is improving an existing asset rather than creating something new. This skill pulls owned pages from AI Visibility, identifies which ones have citation potential but are underperforming, compares them against the external pages that are winning citations on the same topics, and produces section-level rewrites or a full-page update — then pushes the revision to the CMS as a draft. Trigger even if the user just says "help me get cited more" or "why is [competitor] getting cited instead of us".

amplitude/builder-skills

Use this skill whenever a user wants to win AI citations on prompts that competitors currently dominate — whether they say "competitors are getting cited instead of us", "we're losing on these prompts", "how do I outrank [competitor] in AI answers", "find prompts where we should be winning", "create content to beat [competitor]", or any variation where the goal is capturing AI share on prompts a competitor currently owns. This skill pulls competitor visibility data from AI Visibility, identifies the specific prompts where competitors win and Amplitude is absent, clusters them by intent, and produces targeted comparison pages, alternatives content, or rebuttal assets — then pushes drafts to CMS. Trigger on any mention of competitor, prompt hijack, outrank, or "why is [competitor] getting cited instead of us".

amplitude/builder-skills

Use this skill whenever a user wants to turn AI Visibility data into published content — whether they say "find content gaps", "what should we write about", "which topics have low visibility", "help me get cited by AI models", "create a blog post from our AI Visibility gaps", "we're losing to competitors on these prompts", or any variation where they want to go from AI visibility weakness to a draft article, landing page, or FAQ. This skill connects directly to Amplitude AI Visibility data (topics, prompts, visibility scores, citations, competitor data, full LLM responses and sources) and produces a publish-ready content brief plus full article draft. If the user mentions CMS (WordPress, Webflow, Contentful, Sanity, HubSpot, Ghost, Shopify), also trigger this skill to push the draft directly. Trigger even if they just say something vague like "what content should we create?" in an AI Visibility context.

amplitude/builder-skills

Use this skill whenever a user wants to test content variants before publishing to find which one will get cited most by AI models — whether they say "which version of this content will perform better", "test this article before we publish", "simulate how AI will respond to this content", "which angle should we use", "generate content variants and pick the winner", "run a simulation before publishing", or any variation where the goal is data-driven content selection rather than gut-feel publishing. This skill takes an identified content opportunity, generates 2–3 distinct variants with different angles or structures, scores them against actual AI model responses from AI Visibility, references the Simulate Changes feature for pre-publish validation, and produces a clear recommendation on which variant to publish — then pushes the winner to CMS. Trigger on any mention of "simulate", "test variants", "which performs better", "A/B content", or "before we publish".

amplitude/builder-skills

Use this skill whenever a user wants to understand which external sources are being cited by AI models on topics relevant to their brand, and wants to create content that will outrank those sources — whether they say "what sources are AI models citing", "why is [third-party site] being cited instead of us", "we want to be the definitive source on X", "build something that gets cited more than G2 or TechRadar", "create an authoritative asset", or any variation where the goal is producing a new reference asset (definition page, benchmark, methodology, glossary, comparison hub) designed to beat existing top-cited sources. This skill analyzes AI Visibility source data, reverse-engineers what makes top-cited pages authoritative, and produces a superior source asset — then pushes it to CMS as a draft. Trigger on any mention of "sources", "third-party citations", "authoritative content", "definitional pages", or "outrank".

amplitude/builder-skills

Instrument a Node/TypeScript MCP server with Amplitude's @amplitude/mcp-analytics SDK so tool calls, sessions, and rationale are tracked as Amplitude events. Use this skill whenever the user wants to add Amplitude analytics to their MCP server, mentions "MCP Analytics", "@amplitude/mcp-analytics", "instrument my MCP server", "track MCP tool calls", "add rationale to my MCP tools", or wants agent traffic (Claude, Cursor, ChatGPT) attributed back to Amplitude. Also use for adding UTM tagging to MCP-returned links, or for troubleshooting identity/user_id mismatches between MCP events and web/mobile Amplitude data.

amplitude/builder-skills

Instruments a pull request with Amplitude analytics that conform to the project's existing taxonomy. Reads the tracking plan via the Amplitude MCP server (events, properties, naming conventions), analyzes the PR diff to find the few user actions genuinely worth tracking, detects the codebase's SDK and tracking patterns, and adds instrumentation that matches both. Optionally (opt-in) stages new events and properties on an Amplitude tracking-plan branch for data-governance review. Use when asked to "instrument this PR", "add analytics to this change", "add tracking", "add Amplitude events", "instrument this feature", or "what should I track here".

amplitude/builder-skills

Diagnoses product health by cross-referencing Amplitude analytics (dashboards, charts, funnels, feedback, AI agent analytics), optionally Datadog (errors, latency, stack traces), and optionally Slack (qualitative feedback, bug reports, feature requests). Identifies what's broken, what's working, and what to do about it — with root causes, not just symptoms. Use when asked to "diagnose my product", "what's going on", "product health check", "what's broken", "where are users struggling", "give me a product diagnosis", or "what should I focus on".

amplitude/builder-skills

Turn one or more meeting transcripts, notes, or Slack threads into concise takeaways and clear action items with DRIs. Works with a single meeting or a batch from the whole week.

amplitude/builder-skills

Summarizes B2B account health by analyzing usage patterns, engagement trends, risk signals, and expansion opportunities. Use for customer success reviews, renewal preparation, QBRs, or account prioritization.
