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
mdbrain
A native Claude Code extension that prevents AI from over-refactoring your intentional code. Combines XML-structured protocols (BRAIN/CRAFT/PERF) with a 16-entry false-positive catalog, enforced by a five-layer Safety Net: permissions deny list, PreToolUse hook, tool-scoped subagents, path-scoped rules, and behavioral protocols. Coexists non-destructively with existing CLAUDE.md and memory/.
io.brainfile/brainfile
Brainfile memory layer for Claude Code over MCP: free starter files + weekly freshness feed.
