Use this skill when creating, editing, debugging, reviewing, or documenting Standard Agents or AgentBuilder projects. Apply it for work on agents, prompts, models, tools, hooks, threads, APIs, subagents, provider setup, model selection, environment variables, and spec-aligned architecture, even if the user only says things like "build an agent", "write a prompt", "choose a model", or "fix my AgentBuilder app" without explicitly naming Standard Agents.
Writes and reviews semantic, accessible HTML and template markup that stays readable and low-noise. Use when creating or refactoring HTML or Svelte templates, cleaning up div soup, choosing better elements, improving form markup, fixing heading or landmark structure, or replacing custom controls with native HTML.
Master typographer specializing in font pairing, typographic hierarchy, OpenType features, variable fonts, and performance-optimized web typography. Use for font selection, type scales, web font optimization, and typographic systems. Activate on "typography", "font pairing", "type scale", "variable fonts", "web fonts", "OpenType", "font loading". NOT for logo design, icon fonts, general CSS styling, or image-based typography.
Designs or reviews user interfaces that are self-evident, low-friction, and easy to understand with minimal explanation. Use when simplifying UI text, removing helper copy, improving affordances, tightening hierarchy, making forms more obvious, or evaluating whether an interface works without instructions.
Use when the user asks to create, generate, write, or apply a Changesets release note/version bump from current code changes (for example "make a changeset", "add a changeset", "apply changesets", or "version packages").
Use when tracking complex multi-step tasks, creating task hierarchies, maintaining persistent task state across sessions, building backlogs, or when the user explicitly asks to "use dex" for task management. Dex provides persistent memory for AI agents with GitHub/Shortcut sync capabilities.
