Product judgment, packaged for agents.

Stress-tests a PRD or spec like a skeptical VP. Finds the bet, the riskiest assumption, the missing "no" and the kill criteria. Use when asked to review or poke holes in a plan.

Scores a backlog with RICE, then challenges its own scores and insists on a stop-doing list. Use when the user shares a backlog or asks what to do first.

Turns interview transcripts, call notes or survey free-text into evidence-backed themes, plus the one surprising outlier worth chasing. Use when asked for themes, insights or what customers are saying.

Audits or designs a screen, flow or pricing page through 106 cognitive biases, naming the principle at work, the fix and the dark-pattern line not to cross. Use for UX, onboarding or conversion reviews.

Breaks a long PRD into 5–12 shippable chunks, orders them into a Gantt plan and opens with a plain-language why. Use when a spec needs milestones, phases or a delivery roadmap.

Builds or reviews a product vision as one traceable story, from the customer's job to what ships this quarter, with a Hooked habit loop in the middle. Use for vision decks, strategy narratives or tying problems to the roadmap.

Turns a changelog, PR list or ticket dump into short, benefit-first release notes users actually read. Use when asked for release notes, what's new or a changelog entry.

Breaks a north-star metric into levers a team can move this quarter, each with a leading indicator, guardrail and owner. Use when setting OKRs or asked how to move a metric.

Tears down a competitor's positioning, product and pricing without feature envy, ending in one move to make and what not to copy. Use when the user names a competitor or asks how they compare.

Turns "animate this" into working motion code. Decides first whether it should move at all, then picks the cheapest tool (CSS before Motion), the curve and the duration, and ships reduced-motion support with it. Comes with recipes for toasts, drawers, modals and more.

Art-directs and builds motion-led marketing, portfolio and landing sites. Writes a visual direction before any code, then implements it with GSAP, a single smooth-scroll engine and Three.js only where it earns its place, with honest assets and reduced-motion, mobile and keyboard checks.

Emil Kowalski's rules for UI polish and motion. When to animate at all, which easing and duration to use, press and popover details, and keeping animations interruptible, performant and reduced-motion friendly.

Rewrites AI-sounding text so it reads like the person who wrote it, without changing what it says. It hunts 26 tells drawn from Wikipedia's "Signs of AI writing", such as not-X-but-Y contrasts, one-line closers, forced triads, stock words and dashes everywhere, then checks the rewrite against the original so no facts get added or lost.

Makes your coding agent think like the laziest senior dev in the room. Before writing anything it climbs a ladder (does this need to exist, is it already in the codebase, the standard library, an installed dependency) and only then writes the minimum code that works. Comes with review and audit commands that rank findings from must-fix down.

Reviews a codebase for security against framework-specific checklists for Python (Django, FastAPI, Flask), JavaScript/TypeScript (Express, Next.js, React, Vue) and Go. It writes secure-by-default code, flags critical issues as it works, or produces a full prioritized report and then offers fixes one finding at a time.

Runs an SEO audit in priority order, from crawlability and indexation to technical foundations, on-page, content quality and authority. Every finding comes with impact, evidence and a fix, and the result is a tiered action plan of critical fixes, quick wins and long-term work.

Teaches the agent to work with shadcn/ui the way it's meant to be used. It searches registries and reads the docs before writing code, adds components through the CLI, sticks to semantic colors and the composition rules for forms, dialogs and cards, and never overwrites your customizations without asking.

Sets up a design system the Tailwind CSS v4 way, configured in CSS rather than JavaScript. It defines semantic color, radius and animation tokens in @theme, handles dark mode by overriding the same tokens, and builds components in a fixed order of base, variants, sizes and states.

A pack of 13 skills covering the whole Three.js pipeline, from scene setup, materials, lighting and shaders to glTF loading, post-processing, performance and React Three Fiber. Written for current three.js (r186) with WebGPU/TSL sections, and each skill flags outdated APIs the agent would otherwise reach for.

A pack of 9 skills for design engineers. Baseline UI strips the slop out of generated interfaces (spacing, hierarchy, type, no unasked-for gradients or animation). The rest audit and fix accessibility, metadata and motion performance, write a DESIGN.md from an existing product, and build canvases for exploring components.
