nicknisi Skill

Produce a rich, self-contained HTML explainer for a code change — deep background, core intuition with diagrams, a guided code walkthrough, and an interactive quiz. Use whenever the user asks to explain or deeply understand a diff, PR, branch, or commit — "explain this PR", "walk me through this change", "what does this diff actually do", "make an explainer for this branch" — or wants a shareable document that teaches someone else what changed and why. Output is an HTML file opened in the browser, not a chat reply.

owid Bundle

Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use review-animations; for auditing a whole codebase use improve-animations.

pdugan20 Bundle

Diagnose and tune one user-visible performance problem in a Swift, SwiftUI, React Native, or Expo mobile feature by tracing the first missed deadline across motion, rendering, state publication, media, storage, network, and observability, then applying and verifying the smallest causal change. Use when an interaction, animation, scroll, keyboard transition, first paint, or loading path is jittery, stalled, late, or less seamless than expected and the bottleneck is uncertain. Do not use for broad app performance audits, motion ideation or craft review without a runtime symptom, recording-only analysis, backend-only optimization, or release hardening.
