Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
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.
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
Expert prompt engineering for AI systems. Use when the user wants to write or review prompts for AI, create instructions for AI systems, build system prompts, review or improve existing prompts, optimize AI instructions, or create any form of written communication intended for AI consumption (Claude, GPT, or other LLMs).
Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.
Full QA on all session changes using Codex as a second pair of eyes. Use when user says "QA", "full QA", "QA my changes", "QA all your changes", or "use codex to review". Runs git diff, sends changes to Codex for thorough review, and synthesizes findings.
Generate beautiful, self-contained HTML pages that visually explain systems, code changes, plans, and data. Use when the user asks for a diagram, architecture overview, diff review, plan review, project recap, comparison table, or any visual explanation of technical concepts. Also use proactively when you are about to render a complex ASCII table (4+ rows or 3+ columns) — present it as a styled HTML page instead.
Deep multi-agent code review for local changes. Inspired by AmpCode's agentic review. Use when you want comprehensive analysis of staged changes, unstaged changes, specific commits, or branch differences. Spawns parallel specialized agents (security, performance, patterns, architecture) and synthesizes actionable findings with priority levels. Can implement fixes directly.
Orchestrate a team of 10 design agents for holistic UI audit, ideation, and implementation. Use when: "design swarm", "holistic audit", "design review with all lenses", "full design analysis". Modes: audit, ideate, implement (any combination). Targets: screenshots, URLs, file paths, or text briefs.
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.
Diverge-converge workflow: spin up N agents on isolated worktrees, each exploring a different approach to the same problem. Compare results side-by-side (with optional preview ports), pick a winner, merge it back. Use when the user says /iterate, 'try multiple approaches', 'explore different directions', or wants to compare implementations.
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.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Maintain a per-repo napkin as a continuously curated runbook (not a session log). Activates EVERY session. Read and curate it before work, keep only recurring high-value guidance, organize by priority-sorted categories, and cap each category at top 10 items. The napkin lives at `.claude/napkin.md`.
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.
CEO/founder-mode plan review. Rethink the problem, find the 10-star product, challenge premises, expand scope when it creates a better product. Three modes: SCOPE EXPANSION (dream big), HOLD SCOPE (maximum rigor), SCOPE REDUCTION (strip to essentials). Originally from Garry Tan's gstack (https://github.com/garrytan/gstack). MIT licensed.
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.
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.
Use this methodology when collaboratively shaping a solution with the user - iterating on problem definition (requirements) and solution options (shapes).
Cognitive engagement coach based on "Think First, AI Second" principles. This skill should be used when the user asks strategic, architectural, or high-stakes questions, OR when they explicitly request challenge/critique (e.g., "poke holes", "devil's advocate", "challenge this"). Promotes active thinking over passive AI consumption.
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.
