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
E2B
Giving Claude ability to run code with E2B via MCP (Model Context Protocol).
prompt-smith
Prompt Smith adds the /prompt slash command to Claude Code. It takes a rough prompt and rewrites it for clarity, structure, and precision — then shows a side-by-side preview before execution. Four optimization modes (default, agentic, compact, strict) adapt the rewrite to the prompt's intent. Supports --dry-run for preview-only, --yes to skip confirmation, and --mode to select explicitly. Fidelity first: the optimized prompt always preserves the user's exact intent.
