Add, fix, or optimize schema markup and structured data. Use when the user mentions schema markup, structured data, JSON-LD, rich snippets, schema.org, FAQ schema, product schema, review schema, or breadcrumb schema.

Master advanced prompt engineering techniques to maximize LLM performance, reliability, and controllability in production. Use when optimizing prompts, improving LLM outputs, designing production prompt templates, or building AI-powered features.

Create persona documentation for a product or codebase. Use when asked to create persona docs, document target users, define user journeys, document onboarding flows, or when starting a new product and needing to define its audience. Persona docs should be the first documentation created for any product.

Create software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams, sequence diagrams, flowcharts, ERDs, C4 architecture diagrams, state diagrams, git graphs, and other diagram types. Triggers include requests to diagram, visualize, model, map out, or show the flow of a system.

Find 10x product opportunities and high-leverage improvements. Use when the user wants strategic product thinking, mentions 10x, wants to find high-impact features, or asks what would make a product dramatically more valuable.

Write clear, concise prose for humans — documentation, READMEs, API docs, commit messages, error messages, UI text, reports, and explanations. Combines Strunk's rules for clearer prose with technical documentation patterns, structure templates, and review checklists.

Explore ideas before implementation through collaborative dialogue. Use before any creative work — creating features, building components, adding functionality, or modifying behavior. Turns ideas into fully formed designs and specs through structured conversation.

When the user wants to add illustrations to an article or blog post. Triggers on: "illustrate article", "add images to article", "generate illustrations", "article images", or requests to visually enhance written content. Analyzes article structure, identifies positions for visual aids, and generates illustrations using a Type x Style two-dimension approach.

Execute implementation plans by dispatching a fresh subagent per task with two-stage review (spec compliance then code quality). Use when you have an implementation plan with mostly independent tasks and want high-quality, fast iteration within a single session.

Evaluate Agent Skill quality against official specifications. Use when reviewing SKILL.md files, auditing skill packages, improving skill design, or checking if a skill follows best practices. Provides 8-dimension scoring (120 points) with actionable improvements. Triggers on review skill, evaluate skill, audit skill, improve skill, skill quality, SKILL.md review.

WHAT: Guide for creating effective AI agent skills - modular packages that extend Claude's capabilities with specialized knowledge, workflows, and tools. WHEN: User wants to create, write, author, or update a skill. User asks about skill structure, SKILL.md format, or how to package domain knowledge for AI agents. KEYWORDS: "create a skill", "make a skill", "new skill", "skill template", "SKILL.md", "agent skill", "write a skill", "skill structure", "package a skill"

WHAT: Create comprehensive handoff documents that enable fresh AI agents to seamlessly continue work with zero ambiguity. Solves long-running agent context exhaustion problem. WHEN: (1) User requests handoff/memory/context save, (2) Context window approaches capacity, (3) Major task milestone completed, (4) Work session ending, (5) Resuming work with existing handoff. KEYWORDS: "save state", "create handoff", "context is full", "I need to pause", "resume from", "continue where we left off", "load handoff", "save progress", "session transfer", "hand off"
