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
c4m
Interactive C4 architecture diagrams (Simon Brown's model) for Claude Code. Five mode-driven workflows — Design (greenfield), Document-code (retro-doc from a repo), Document-prose (from README/ADR/spec), Review (critique an existing diagram), Update (evolve one) — accessed via /c4m:auto, /c4m:design, /c4m:code, /c4m:prose, /c4m:review, /c4m:update. Output is one Markdown document per C4 level with embedded Mermaid; format negotiable (Structurizr DSL, PlantUML) and destination negotiable (filesystem or MCP — Notion, Linear, Drive). Enforces the editorial invariants: technology mandatory on every Container/Component, intent-specific relationship labels, protocol on inter-container links, assumptions kept explicit.
io.github.neo4j-contrib/mcp-neo4j-data-modeling
