Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

Each skill auto-loads only when relevant to the task: Web Accessibility on UI work, SEO/LLMO before launch, Core Web Vitals on performance issues, AWS SPA deploy on Amplify/CDK work, and Google Analytics 4 on tracking setup. Originally distributed as standalone markdown guides for any AI tool (also available via npx ai-instruct init); now packaged as a single Claude Code plugin for one-command install.
