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
agent-discovery
Agent Discovery lets developers discover, review, install, and manage AI agent configurations from a curated catalog of 687+ entries — with zero setup. It ships a pre-built SQLite index of agents, skills, and instructions from awesome-copilot and GitHub's Agent Factory, so search is instant and requires no API keys or authentication. The interactive /recommend flow analyzes your project's tech stack, surfaces relevant agents with explanations, then guides you through reviewing content before installing, customizing in your editor, or assembling multiple agents into a coordinated team with an agentic lead. Additional /list and /edit commands let you manage everything you've installed without leaving Claude Code.
