Applies Steve Blank's Customer Development methodology from The Four Steps to the Epiphany. Use when a startup is searching for customers and a business model before scaling. Covers the four-step process: Customer Discovery (find if anyone wants what you're building), Customer Validation (prove you can sell it repeatably), Customer Creation (drive demand matched to Market Type), and Company Building (transition from learning org to execution org). Triggers include 'we built it but no one's buying', 'should we hire salespeople yet', 'how do we find our first customers', 'we're burning cash and sales aren't scaling', 'are we in a new or existing market', 'when do we scale'. NOT for companies that have already crossed the chasm into mainstream (use Crossing the Chasm instead), not for optimizing an existing sales funnel, not for product development methodology (this is its companion, not replacement).
Cialdini's seven principles of compliance (reciprocation, commitment-consistency, social proof, liking, authority, scarcity) plus Unity (added 2016) and Pre-Suasion. Use when crafting ethical persuasion (marketing, sales, negotiation), defending against manipulation, or designing systems that need cooperation. Includes replication-crisis caveats and known factual corrections (Bickman parking-meter numbers, Hofling modern replication, Drive Carefully condition disambiguation, Genovese myth).
Independent model QA expert who audits ML and statistical models end-to-end - from documentation review and data reconstruction to replication, calibration testing, interpretability analysis, performance monitoring, and audit-grade reporting.
Evaluate and respond to inbound PostHog sales leads from Salesforce. Use this skill when any PostHog TAE needs to triage an inbound lead — deciding whether to qualify for a call, route to self-serve, or disqualify — and then draft an appropriate response email. Checks Vitally for existing account context before qualifying. Triggers on "respond to this lead", "triage this inbound", "write a response to this lead", "disposition this lead", "evaluate this Salesforce lead", or any request involving an inbound sales inquiry that needs qualification and a reply. Also trigger when a TAE pastes or describes lead details and asks what to do with them.
Evaluates which SaaS tools can be replaced with AI agents. Takes a list of current SaaS subscriptions with costs, assesses replacement feasibility, estimates build vs buy economics, identifies Claude+MCP alternatives, and generates a comprehensive replacement plan with priority matrix, ROI analysis, implementation timeline, and risk assessment.
Pixel-faithful clone of any web UI into the user's existing stack, using whatever sources are available — a screenshot alone, a live URL, raw HTML/CSS, or any combination. Use this skill whenever the user wants to recreate, match, replicate, or "clone" a design from a screenshot, image, URL, Figma export, or HTML dump. Trigger on phrases like "clone this", "match this design", "build this from screenshot", "recreate this page", "make it look like this", "rebuild this UI", "copy this layout", or any time the user provides a visual reference and asks for a faithful implementation. Do not undertrigger — even if the user just drops a screenshot without explicit phrasing, this skill applies.
Help users replan their lives from the top level of NLP understanding hierarchy; use this when users feel confused, trapped in a daily execution loop, and don't know how to break through the current situation
Use when a feature, bugfix, review, planning, implementation, verification, commit, push, or PR task needs orchestration across multiple project skills. Maestro is the entry point for full-cycle engineering work: classify the request, choose the right domain/framework skills, enforce planning/build/publish gates, and carry the task from intake to done without replacing the specialized skills it coordinates.
Use this skill when > Migrate TypeScript test files from unsafe `as` type assertions to type-safe alternatives from @total-typescript/shoehorn. Replace `obj as Type` with fromPartial(), `obj as unknown as Type` with fromAny(), and complete specs with fromExact(). Test code only — never use in production.
Plan or execute a replication of a paper, claim, or benchmark. Use when the user asks to replicate results, reproduce an experiment, verify a claim empirically, or build a replication package.
Mutating operations on the user's Longbridge price alerts — list (read-only), add a new price alert, enable / disable an alert, delete an alert. Requires longbridge login. Every mutation (add / delete / enable / disable) requires a two-step preview + confirm protocol. Use only when the user gives a clear imperative ("set a price alert at 200 for NVDA", "delete alert 486469", "提醒我 NVDA 涨到 200"); ambiguous prompts ("整理我的提醒") must be rejected with a "please be more specific" reply rather than triggered. Triggers: "设置股价提醒", "添加股价提醒", "提醒我 X 涨到 Y", "提醒我 X 跌破 Y", "删除股价提醒", "关掉提醒", "暫停提醒", "設置股價提醒", "添加股價提醒", "提醒我 X 漲到 Y", "提醒我 X 跌破 Y", "刪除股價提醒", "關掉提醒", "set price alert", "add price alert", "alert me when X hits Y", "delete price alert", "enable alert", "disable alert", "price alert".
Extract BUAA classroom replay artifacts from `livingroom` or `coursedetail` URLs by reusing a local Chromium login session. Use when Codex needs replay metadata, course-transcript files, optional PPT auxiliary artifacts, replay-ready lesson lists, or a standalone semantic rebuild packet / final lesson note.
