Turn reference docs into active mastery through retrieval practice, case binding, and scenario simulation. Combines Skycak (learning science) and Chin (expertise acceleration) frameworks. Use when you want to deeply learn material, not just read it.
Coach users on storytelling, communication, and influence using 45 practitioner-tested techniques from Lenny Rachitsky's archive. Use when drafting presentations, preparing for stakeholder conversations, writing executive communications, pitching ideas, seeking buy-in, or improving persuasion. Triggers on "how should I present this", "help me pitch", "get buy-in", "convince", "influence", "stakeholder prep", "improve my writing", "presentation feedback", "storytelling", "executive presence", "meeting prep", or any request to make a communication more compelling.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
Master multi-agent orchestration using Claude Code's TeammateTool and Task system. Use when coordinating multiple agents, running parallel code reviews, creating pipeline workflows with dependencies, building self-organizing task queues, or any task benefiting from divide-and-conquer patterns.
Domain-grounded judgment for creation: code, visuals, documents, design, data artifacts, and other output where quality depends on choosing what not to include. Use this skill when the user wants something to feel authored rather than generated, when the brief says a draft feels off, when polish alone is insufficient, or when the deliverable is externally visible and the quality bar is shaped by practitioner norms. Triggers on requests like 'use taste', 'apply taste', 'make this good', 'tighten this', 'clean this up', 'less is more', 'this feels generated', or any creation task where judgment matters more than coverage. Do not use for exhaustive extraction, rote transformation, or work where comprehensiveness is the explicit goal.
Expert coach for learning, mastering, and upskilling in any domain. Use when the user wants to learn, master, improve, upskill, get better at, or get coached on any topic. Helps build consistent practice habits, identify prerequisites, design efficient learning loops, avoid common pitfalls, maintain discipline, and measure progress. Based on evidence-based principles from "Advice on Upskilling" by Justin Skycak.
B2B startup strategy advisor grounded in Lenny Rachitsky's 7-part series and April Dunford's positioning framework. This skill should be used when the user asks about B2B go-to-market, positioning, finding first customers, validating a B2B idea, identifying ICP, scaling growth engines, hiring early teams, or finding product-market fit. Also triggers on B2B pricing, or "how do B2B startups" questions.
