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
thinking-partner
A deterministic thinking partner that challenges assumptions and applies 150+ mental models across 17 disciplines to sharpen decisions, solve problems, and think more clearly. Features include orientation detection that diagnoses 6 thinking states with targeted interventions, a structured 6-step workflow from diagnosis to synthesis, 7 complementary cognitive operation pairs, and explicit anti-patterns to avoid common reasoning failures. Works as a sparring session, not a lecture, asks one question at a time, names the model being applied, and challenges where it matters.
