changelog-generator vs vercel-react-view-transitions

Both skills were run through Claude twice: once on a fixed brief without the skill, once with it. The briefs differ because each is written for the job the skill claims to do, so compare each skill against its own baseline, then decide which difference matters for your work. They are in different categories, so this is a choice of job, not a head-to-head on the same job.

changelog-generator

Automatically creates user-facing changelogs from git commits by analyzing commit history, categorizing changes, and transforming technical commits into clear, customer-friendly release notes. Turns hours of manual changelog writing into minutes of automated generation.

Brief: “Build a photo gallery for a small travel photographer as a single HTML page using React from a CDN: a grid of twelve photos drawn with inline SVG or CSS gradients, where clicking a photo smoothly expands it into a detail view with a caption and location, and going back animates it into its place in the grid. Filtering the grid by country should animate the reordering too.”
