Interfaces DS: An Opinionated Design System on shadcn/ui
A design system built on top of shadcn/ui where every component has been tweaked to reflect a specific aesthetic sensibility.
The real value here is the idea that design systems should have a point of view — shadcn gives you the primitives, but taste comes from opinionated defaults.
Plan Reviews with Diagrams Shake Out Bugs
The /plan-eng-review skill lets you request diagrams — user flows, data flows, branching — and the act of creating them surfaces edge cases and bugs.
The insight isn't about AI generating diagrams. It's that forcing a system to explain itself visually is a debugging technique — diagramming is thinking.
Agentation: Visual Feedback Tool for AI Agents
Click UI elements, add notes, and generate structured context that AI coding agents can understand — visual annotation for agent-powered fixes.

A Sufficiently Detailed Spec Is Code
A critique of the 'future of coding is specification' narrative — arguing that detailed specs inevitably devolve into pseudocode, defeating the purpose.
A contrarian take worth sitting with. If your spec has to be precise enough for an agent to execute, you're just writing code with extra steps. The real question is where the useful abstraction boundary lives.
Stop Slop: Remove AI Writing Patterns from Prose
A tool that detects and removes common AI writing patterns from text, making AI-assisted prose read like it was written by a human.
The problem isn't AI-generated text — it's that AI-generated text all sounds the same. This tool attacks the homogeneity, not the generation.
