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
using-cmux
A Claude Code plugin that teaches the agent to operate cmux, a terminal multiplexer with first-class agent integration. Provides skill patterns and shell wrappers (cmux-send, cmux-read, cmux-send-key, cmux-grid, cfork) for the full sub-agent lifecycle: launch -> trust detection -> prompt -> completion detection -> result collection. Browser automation is covered to the depth needed for a single agent. Companion plugin cmux-team handles multi-agent orchestration on top of using-cmux. macOS / Linux only.
radius
