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
experimental-engineer
A Claude Code subagent that explores unconventional, first-principles solutions to hard technical problems, pushing Claude out of its normal tendency to play it safe and stick to the smeared average of its training data. Channels John Carmack-style fearless engineering.
chat-fork-map
Maps branching Copilot conversations so parallel follow-up questions and exploration paths from complex tasks or learning can be navigated without losing context. Its visual layout makes breadth-first exploration easier than managing multiple active threads in a traditional conversation list.
