02OPINIONS & TUTORIALS

I HANDED A UX REVIEW OVER TO AI. HERE'S WHAT HAPPENED

A UX practitioner tested Claude Fable 5 and ChatGPT-5.6 Sol against manual analysis on a real portal review, feeding both models the same brief, research, and analytics data. Both AI models generated reviews filled with irrelevant or invented issues, though Claude proved somewhat more accurate and produced a single coherent document. The author concluded AI works best as a partner grounded in expert-defined heuristics rather than a replacement, and plans to build a custom "agent skill" encoding personal UX judgment for future projects.

HOW FIGMA STAYS AHEAD OF VULNERABILITIES WITH AGENTS

Figma's security team built agentic systems that guard code generation, review pull requests, and audit its decade-old monorepo, all governed by one shared policy. Prioritizing precision over recall proved essential, since historical bugs only measure recall while trust requires developers see mostly valid findings—the team hit 70% precision before enabling PR comments, later reaching 80%. The resulting policy became a de facto threat model, powering hooks that steer secure code generation, adjudication passes that boost recall, and feedback loops that continuously refine detection from bug bounty reports and false-positive dismissals.

A CONCRETE DEFINITION OF “PRODUCT SENSE” (AND HOW TO BUILD IT)

As AI takes over more execution work, product sense—the ability to decide what to build—is becoming increasingly valuable, but it requires more than consuming product critiques, research, and industry knowledge. Strong product sense develops by repeatedly completing the full product cycle: understanding problems, making decisions, implementing solutions, measuring outcomes, and reflecting on whether experience-based patterns actually applied. Building reliable intuition therefore requires staying close enough to your work to see its consequences, while recognizing when unfamiliar or misleading situations demand evidence rather than instinct.

ACCESSIBILITY IS RESISTANCE!

A blind author explains why they rely heavily on AI tools, using an inaccessible EAA document and image-poor product pages as examples. Screen readers, ChatGPT/Claude, Meta Ray-Bans, and apps like Oorion help them navigate text, describe images, and locate objects independently. They distinguish "AI as augmentation" from "AI as compensation," arguing better human-built accessibility would reduce reliance on AI, and urge readers to prioritize accessibility as a form of resistance.

PLAYFUL RETAIL IS SERIOUS DESIGN WORK

Interactive retail spaces that feel spontaneous, like the Coach Charm Playground at Selfridges, actually require immense hidden planning and discipline to execute safely and smoothly, according to Studio XAG. The project involved navigating regulations, testing over 150 sample sets, and executing overnight installs with precision compared to a Formula One pit stop. Key lessons highlighted include protecting the core idea through production, learning from workshop fabricators, and prioritizing real human behavior over portfolio aesthetics.
