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
spec-engine
Spec-driven development engine: turns feature specs into working code through structured requirements, wave-based parallel agent execution, and automated quality gates.
Go Spec Reviewer
Review Go design documents before implementation begins — catches over-engineering, missing error paths, interface misuse, and Cobra/Viper convention violations while a plan is still cheap to change.
