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
Zen
Bridges multiple AI models and CLIs, enabling orchestrated workflows across Claude Code, Gemini CLI, Codex CLI, and other AI development tools.
neko-harness-doctor
Diagnose your Claude Code harness (CLAUDE.md, settings.json, .mcp.json, hooks, skills, memory, MCP servers, and workflow) against 25 anti-pattern indicators. Outputs an S–E overall grade, per-category scores, violations with evidence citations, and prioritized Quick Wins. Includes an interactive fix flow: `--fix-mode propose` emits structured JSON proposals that Claude Code applies via the Edit tool with per-item user approval. Deterministic (no LLM — grep/AST/JSON only), zero runtime dependencies, bilingual (Japanese default, English via `--lang en`). When installed as a plugin, the bundled skill auto-triggers on natural-language requests like "diagnose my harness" and exposes `/neko-harness-doctor` as a slash command.
