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.
What each says it does
code-atlas-mcp
A code intelligence graph that gives AI coding agents deep, token-efficient understanding of your codebase.
han-ddd
Strategic Domain-Driven Design analysis for the Han suite. Discovers domain boundaries, identifies bounded context candidates (strongly expressed, latent, and speculative), finds boundary leaks, and produces an evidence-backed domain and context map for an existing codebase. Depends on han-communication and han-core. Opt-in: not bundled by the han meta-plugin.
