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
writ
Hybrid RAG rule retrieval and workflow enforcement for Claude Code. A five-stage pipeline (BM25 + vector + graph traversal + two-pass ranking) retrieves the right coding rules for each task in under 1ms from a Neo4j knowledge graph,. 726x context reduction vs loading a full rulebook at 10K rules. A mode and gate state machine enforces workflow discipline at the tool-call boundary: - writes are blocked until plans and tests are approved. - Ships with 276 rules across 12 domains (Security, Clean Code, DRY, SOLID, Architecture, Testing, Error Handling, Performance, Scaling, API Design, Process, Documentation). - AI agents can propose new rules through a structural gate; frequency-driven graduation and human review control what stays.
