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
n8n
Bridges n8n's workflow automation platform with AI models, providing access to 543 n8n nodes, workflow templates, and AI-capable automation tools.
harness-designing-plugin
Harness Designing Plugin helps design teams turn their scattered AI setup — Notion prompts, Figma comments, AGENTS.md rules, chat histories — into a five-layer design harness that compounds across sessions and rotations. Four skills walk you through the assembly: • /hd:learn — Q&A about the five-layer concept (Context Engineering, Skill Curation, Workflow Orchestration, Rubric Setting, Knowledge Compounding) • /hd:setup — detects existing harness artifacts, pre-analyzes all five layers in parallel (5× harness-auditor + rubric-recommender), then walks you through link / critique / scaffold / skip per layer • /hd:maintain — captures lessons and promotes them to team rules in AGENTS.md with SHA-256 plan-hash proof-of-consent • /hd:review — audits harness health in a 2-batch parallel dispatch (5 layer-specialist agents + 2–3 context agents); critiques harness artifacts against quality rubrics Ships 9 sub-agents and 14 starter rubrics (distilled from pbakaus/impeccable, Nielsen's 10 heuristics, Material 3, Fluent
