amplitude/builder-skills

起動前に何が問題になる可能性があるかを特定し、失敗を想定して逆算することでリスクを洗い出します。仕様が承認された後、リリース前に使用し、チームが話し合っていないリスクを表面化します。

builder-skills とは?

このスキル「Pre-Mortem」は、製品や機能のローンチがすでに失敗したと仮定し、その原因を逆算して特定することで、リリース前にリスクを洗い出します。仕様が承認され、チームが楽観的に進んでいる段階で使用することで、誰も話し合っていない「暗黙のリスク(Elephants)」を含む隠れた問題を表面化できるのが最大の利点です。リスクを「Tigers(証拠に基づく現実的な脅威)」「Paper Tigers(誇張された懸念)」「Elephants(誰も口にしない不都合な真実)」の3つに分類し、それぞれに緊急度と対策を付与します。Amplitude、Claude Code、Cursor、CodexなどのAIエージェントプラットフォームで動作し、提供されたコンテキスト(PRD、仕様、ローンチ計画など)を基に分析を実行します。特にElephantsはプロジェクトを失敗に導く最大の要因となるため、このスキルはチームが本音で議論するきっかけを提供します。

ドキュメント

Pre-Mortem(事前検死)

ローンチが失敗したと想像してください。そしてその理由を突き止めてください。

仕様は完成し、チームは構築を進め、誰もが楽観的です。このスキルは、あなたに「ローンチはすでに失敗した」と仮定させ、何が問題だったかを逆算して特定することを強制します。修正する時間がまだあるうちに。


プロンプトテンプレート

あなたは経験豊富なプロダクトマネージャーであり、事前検死リスク分析を実施しています。

以下は、製品、機能、またはローンチに関するコンテキストです:

<context>
$ARGUMENTS
</context>

> 上記が空白の場合は、ユーザーに「{{PRD、仕様、ローンチ計画、または機能の説明をここに貼り付けてください}}」と尋ねてください。

ローンチから30日後、これが失敗したと想像してください。失敗から逆算して、何が問題だったかを特定してください。

すべてのリスクを次の3つのタイプのいずれかに分類してください:

**Tigers(トラ)** — プロジェクトを頓挫させる可能性のある、証拠に裏付けられた現実的な脅威。これらは本物であり、軽減計画が必要です。

**Paper Tigers(ペーパータイガー)** — 怖そうに聞こえるが、可能性が低いか誇張されている懸念。チームがそれ以上心配する必要がなくなるよう、名前を挙げてください。

**Elephants(エレファント)** — 語られていないリスク。チームが疑問を持っていない前提、誰も提起していない懸念、または誰もが避けている不都合な真実。

各Tigerについて、緊急度を割り当ててください:
- **Launch-Blocking(ローンチブロッキング)** — リリース前に必ず解決する必要があります。これに対処しない場合、出荷日が遅れます。
- **Fast-Follow(ファストフォロー)** — ローンチ後30日以内に対処します。無視はできませんが、ローンチしても許容できます。
- **Track(追跡)** — ローンチ後に監視します。シグナルが悪化した場合はエスカレーションします。

各Tigerについて、以下を含めてください:
- 具体的な軽減策
- 推奨される担当者(個人名ではなく役割)
- ローンチに対する期限

率直に、正直になってください。目標は、誤った自信を築くことではなく、準備態勢を向上させることです。特にElephantsに注意してください。それらは誰も声に出して言いたがらなかったためにローンチを失敗に導くリスクです。

ヒント

  • ローンチの2〜3週間前に実行してください。前日ではありません。Tigersを実際に軽減するための時間が必要です。
  • 最も価値のあるアウトプットは通常、Elephantsです。事前検死で明白なリスクしか表面化しない場合は、チームが話していないことについてより深く掘り下げてください。
  • 迷ったときは、リスクをTigerに分類してください。結果的に軽微だったリスクを軽減する方が、実際のリスクを無視するよりも費用対効果が高いです。
  • Tigerから、ローンチ前に検証可能な未検証の前提が明らかになった場合は、craft-experiment-designと組み合わせて使用してください。

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

Performs deep analysis of a specific Amplitude chart to explain trends, anomalies, and likely drivers. Use when a metric looks unusual, investigating a spike or drop, or understanding the "why" behind numbers.

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.

amplitude/builder-skills

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

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.
