Evidence-based interface inspection and GOMS/KLM, Fitts and Hick-Hyman task models over MCP

Human-rate mouse and keyboard for a real Chromium browser: one you launched, the one you are logged into, or an agent-browser session. Drives it over raw CDP at 60-100Hz with Fitts-law motion, Bezier paths and lognormal keystroke timing, without touching

Biomechanical input synthesis for mochi — cubic Bezier + Fitts's Law + Gaussian jitter for humanClick / humanType / humanScroll.

Hit-slop utilities for Tailwind CSS v4 (and v3 via plugin) — invisible expanded touch targets, like React Native's hitSlop.

Convenience layer for Cloudflare Turnstile auto-click — opt-in, behavioral-synth-backed, no new fingerprint surface.

The library for faithful browser automation. Bun-native; relational fingerprint matrix, biomechanical input, stock Chromium-for-Testing.

Static anti-slop detector for UI code. Flags AI-generated design patterns (purple gradients, bounce easing, glassmorphism, generic CTAs, ALL CAPS headings, transition: all). Zero dependencies, works out of the box.

Agent-drivable Patchright browser daemon with a persistent Chrome profile AND a built-in human-behavior layer (realistic mouse paths, keystroke cadence, scroll physics). Gives AI coding agents (Claude Code, Cursor, Codex, Gemini CLI) a real browser they c

A generative design system based on physical laws, not static values. Every dimension, color, and motion is derived — never hardcoded.

Design skills, commands, and anti-pattern detection for AI coding agents

This package provides a set of utilities to optimize the ordering of entries in a linear menu (e.g one-level menu).

MCP server for Claude Code that stops AI-generated frontend from looking like slop

Human interaction verification through behavioral biometrics. Analyzes mouse movement, click patterns, keystroke dynamics, scroll behavior, touch pressure, and device sensors to distinguish humans from bots.

Canonical global-optimization benchmarks and classical psychophysical laws, with per-axis domains and known optima. Zero dependencies.

An AI agent skill for reviewing UIs against 25+ psychological UX laws, WCAG 2.2 accessibility criteria, and Nielsen's 10 usability heuristics — with quantitative 0-100 scoring.

Effy, a personified robot, helps determine the efficiency of computer interfaces.
