ai
Use when working with AI agent protocols, standards, and interoperability specifications. Covers MCP, A2A, ACP, Agent Skills, AGENTS.md, ADL, x402, AP2, MCP Apps, and cagent. USE FOR: agent protocol selection, comparing MCP vs A2A vs ACP, understanding agent standards ecosystem, choosing payment protocols DO NOT USE FOR: specific protocol implementation details (use the sub-skills: mcp, a2a, acp, x402, etc.)
npx skills add majiayu000/claude-skill-registry --skill ai-tyler-r-kendrick-agent-skills --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# AI Agent Protocols & Standards ## Overview This skill covers the emerging ecosystem of open standards and protocols for AI agents. These specifications define how agents discover capabilities, communicate with each other, make payments, render UI, and are described declaratively. ## Protocol Landscape | Protocol | Purpose | Maintained By | |----------|---------|---------------| | **MCP** | Tool integration — how agents use tools and access context | Anthropic | | **A2A** | Agent-to-agent communication and task delegation | Google | | **ACP** | REST-based agent communication (merged into A2A) | IBM / BeeAI / Linux Foundation | | **Agent Skills** | Skill packaging — how capabilities are discovered and loaded | Anthropic | | **AGENTS.md** | Project-level guidance for coding agents | Community | | **ADL** | Declarative agent definition (identity, tools, permissions) | Next Moca / Eclipse LMOS | | **x402** | HTTP-native micropayments using stablecoins | Coinbase | | **AP2** | Secure agent-driven commerce and purchases | Google | | **MCP Apps** | Rich interactive UI served by MCP servers | Anthropic | | **cagent** | Multi-agent runtime with YAML configuration | Docker | ## How They Rel

What does the ai skill do?
Use when working with AI agent protocols, standards, and interoperability specifications. Covers MCP, A2A, ACP, Agent Skills, AGENTS.md, ADL, x402, AP2, MCP Apps, and cagent. USE FOR: agent protocol selection, comparing MCP vs A2A vs ACP, understanding agent standards ecosystem, choosing payment protocols DO NOT USE FOR: specific protocol implementation details (use the sub-skills: mcp, a2a, acp, x402, etc.)
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill ai-tyler-r-kendrick-agent-skills --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
