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
drift-detect
Deep repository analysis to realign project plans with actual code reality. `/drift-detect` discovers drift between documented plans (CHANGELOG, ARCHITECTURE.md, design docs, README claims) and what the code actually does, then produces a prioritized reconstruction plan. Pure JavaScript collectors gather data fast (no LLM overhead) and a single Opus call performs the deep semantic analysis - 77% fewer tokens than multi-agent approaches. Tested on 1,000+ repositories. Outputs a ranked list of drift items with severity, evidence, and suggested resolution.
