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
Semgrep
MCP server for using Semgrep to scan code for security vulnerabilities.
SLM Agent by ScaleDown
SLM Agent scans your codebase for AI API calls and generates a structured migration plan showing exactly where you can swap frontier LLM calls (Opus) for Small Language Models API calls like Haiku or Sonnet. It performs deep cross-file analysis: tracing prompts to their construction site, following callers across files, and classifying each call by what it actually does. Each finding includes a complexity score, confidence level, estimated savings, and for multi-task calls, a step-by-step decomposition. The output is a saved report.md in your project with a full API reference, so you can migrate. No source code or codebase data is sent to any external server (except Claude) during analysis.
