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
aria-knowledge
ARIA is automated knowledge capture, management, and application for Claude Code. It actively learns during AI-assisted development sessions — insights, decisions, patterns, gotchas — and promotes validated knowledge into an indexed markdown knowledge base that is proactively applied in sessions and on every edit to improve development and accuracy. It runs in Claude Code, fully local. Core feature sets are: Knowledge Lifecycle — automatic capture from conversations and pre-compaction transcripts, staging backlogs, review workflows, promotion to tagged files, staleness detection, and archival. A pipeline from raw signal to validated knowledge. Decision Discipline — hook-enforced impact assessment on every file edit, change framework with scope verification, pre/post edit checks, configurable critical paths, and abbreviated mode for planning docs. Not guidelines — active enforcement. Contextual Retrieval — tag-based indexing with cross-references, on-demand knowledge loading by topic, project tag expansion, en
