Figma designer advocates Brett McMillin and Kaitie Chambers take static museum app screens to a finished launch live: agent-generated keyframes become animation styles, which use easing and timing variables, so changing one curve updates every screen. Variable modes then switch the same motion between a smooth and an expressive feel. ​“Motion can now finally be treated as part of the design system fully instead of something you have to build every time.”

Hairline 0.5px borders keep strokes crisp until you put them on a small corner radius, like a checkbox. Then antialiasing gets funky, especially in dark mode. Matt Ström-Awn’s workaround is two overlaid rectangles with carefully-tuned concentric radii.

Main-stage talks from Lenny & Friends Summit, with Marty Cagan on strong opinions loosely held and Claire Vo on whether any of the extra shipping matters. Start with Katie Dill of Stripe, who warns that AI building could leave us with ​“zombie UI that’s monotonous, vacant, or uncared for.”

Josh Puckett’s advice for junior designers on asking for help: be direct, specific and concise, follow up, and follow through. Start with the rewrite of weak asks like ​“Here’s my portfolio, let me know if you have thoughts!” into requests with a clear question and a time commitment.

“Saying what you’re not filters as hard as saying what you are.” Danny Martinez, co-founder of Decimals, on why the CEO of Arrows telling candidates up front that his company isn’t a 996 shop made a designer email him right away, and soon after take the job.

Peng Zheng’s personal site updates itself, as he shows host Claire Vo on How I AI. Send his check-in bot a photo, a screenshot or just the name of a place, and it looks the place up through the Google Places API, fixes the perspective, removes people and generates light and dark 3D miniature versions for the site.

Brett McMillin, Designer Advocate at Figma, runs a skill that pulls user personas from a Notion page and critiques selected frames as one persona, in his demo a fintech app for teens. The findings land as annotations on the canvas covering comprehension, findability, visual hierarchy and trust, and the skill is told never to touch the design. ​“Nothing will take the place of actual user testing and talking to our customers.”

Why stay in the details when agents can do the hard part? Geoffrey Litt, design engineer at Notion, says the time spent in the nooks and crannies of a problem loads your memory with the raw material your brain recombines later, even in the background. His choice for the AI era: get lazy and settle for good-enough, or work harder than ever. ​“You can already start to tell who is taking each path.”

A checklist for spotting AI-generated interfaces, written after a college app’s ​“minor UI improvements” update. Gradients everywhere, pulsing ​“active” badges that can never be inactive, fingernail cards, glassmorphism, and taglines built from ​“Elevate”, ​“Seamless” and ​“Unleash”.

Anton Lovchikov, Head of Design at Evil Martians, makes the case that ​“a designer’s main job isn’t drawing screens. It’s pulling rules out of chaos and making sure they’re followed.” His proof is a 700-line localization refactor, after which Claude rewrote half the strings. The fix was a three-layer system of product principles, copy rules traced back to them, and skills built on those rules. Now when he dislikes a string, he asks Claude which rule produced it and fixes the rule.

Evil Martians’ eight-part framework for keeping AI-built interfaces consistent. Component contracts say when to use and not use each component, an inventory lets agents shortlist components before reading any code, and a design linter fails the build on a raw hex color. The agent skill is published too, split into craft and use workflows.

Jeff Smith of Fieldwork benchmarked frontier and open-weight models on adding icons to an existing set, with humans grading recognizability, process, consistency and execution. His summary: ​“they’re steadily improving execution, their choices often overly literal.”

Figma’s mobile app gets a page dropdown, a frame preview slider, share links to the exact page or frame you’re viewing, and export of individual frames and images to your phone with format and size options.

Custom animation styles ​“let you define your brand’s motion language and create reusable animations that can be applied to any object.” A style is built from one or more preset animations, and the timing and easing inside it can use variables, so the motion follows your design system.

Pulsar Haptics from Software Mansion lets you bind a haptic preset to any layer, hear it as you edit and feel it on a real phone by pairing with a QR code. It needs a free Pulsar account and a plugin subscription, with a 14-day trial.

Manuel Muñoz Solera, aka mamuso, turned his personal site into a shelf of fake Famicom-style game cartridges, one per job. On a phone, long-press a cartridge and blow into the mic and it tilts back and shakes in the wind, the same ritual as blowing on a Nintendo cartridge.
