ar vs comfy-skills

ar: Agent Receipts is an open protocol for generating cryptographically signed audit trails for AI agent actions. It provides SDKs in Go, TypeScript, and Python, plus an MCP proxy that intercepts and signs agent tool calls using Ed25519 signatures. The receipts can be verified independently, enabling accountability and traceability in agentic systems.; comfy-skills: Comfy Skills is the home of Comfy Cloud skills and plugins for AI coding agents: slash commands and an MCP connection that let an agent generate images, video, audio and 3D, and search models and nodes. The comfy-cloud plugin bundles the hosted MCP connection and the commands.
