Skill UI

This framework analyzes foundational design principles—such as affordances, signifiers, and conceptual models—to create products that are highly intuitive and discoverable. It guides analysis by bridging the 'Gulf of Execution' and the 'Gulf of Evaluation.' Use this when diagnosing confusing user interfaces, poor usability, or needing to ensure a product is robustly human-centered and easy to understand.

This framework outlines the 'Hook Model' (Trigger, Action, Variable Reward, Investment) for building deeply engaging, habit-forming product loops. It guides designers in optimizing user retention, understanding behavioral psychology, and structuring product features to move users from deliberate usage to automatic, routine behavior. Use it for onboarding, feature design, and improving long-term user stickiness.

Collection of eight production-ready product agent skills and plugins for Claude Code, Codex CLI, OpenClaw, and others, covering PM toolkits, UX/UI design, SaaS scaffolding, research, and prioritization using Python stdlib tools.

A comprehensive collection of agent skills for rigorously auditing digital interfaces and user flows. It evaluates designs against 168 research-backed UX/UI principles, detects common design antipatterns, and provides specialized review for AI-powered interfaces, ensuring adherence to modern best practices.

This skill applies behavioral economics, specifically prospect theory, to frame messages emphasizing the cost of inaction (loss) rather than just the benefits of action (gain). It guides the creation of persuasive copy, UX copy, and pricing strategies by setting credible reference points and quantifying the missed opportunity. The goal is to ethically leverage the psychological pain of delay, ensuring the approach remains credible and avoids manipulative fear-mongering.

This skill applies principles of behavioral psychology and choice architecture to redesign user experience (UX) flows. It is used when a product's conversion friction is rooted in interaction design, not just copy. By auditing cognitive load, defining optimal default paths, and inserting strategic commitment points, it guides users toward desired actions ethically, maximizing commitment while preserving autonomy. Ideal for improving onboarding, checkout funnels, and complex decision-making sequences.

Defines a premium UI/UX persona that enforces agency-grade typography, textures, and motion choreography, guiding AI to avoid cheap defaults and deliver cinematic, tactile web experiences in varied archetypes.

This expert system is designed to act as an Arch Linux specialist, diagnosing and resolving complex system issues using best practices for rolling-release distributions. It guides users through step-by-step triage plans, leveraging native tools like pacman, systemctl, and journalctl. It provides actionable, copy-paste-ready commands for remediation, verification, and cleanup, ensuring stable system recovery.

Guides designers through using the Penpot MCP tools to craft professional UI/UX for web, mobile, and desktop apps, covering workflows, design systems, accessibility checks, and setup/troubleshooting steps for the Penpot MCP server.

Guides Power BI visualization and UX decisions—capturing business context, selecting optimal charts, specifying layouts, color, typography, and interaction patterns to create accessible, insight-driven dashboards across audiences.

This skill rigorously audits UI code against established design system conventions, focusing on adherence to design tokens, component ergonomics, accessibility standards, and mobile UX best practices. It ensures that the implementation is consistent with the defined style guide, providing a structured verdict and concrete, actionable fixes.

This skill provides a deep audit of user experience (UX) and usability, going beyond basic visual checks. It systematically evaluates screens, flows, and components against Nielsen's 10 usability heuristics and modern mobile best practices. Use it when you need to identify structural flaws, cognitive load issues, or navigation regressions in a product design, providing prioritized issues, violated heuristics, and concrete remediation steps.
