Praesidia

Praesidia extends your AI assistant with the ability to verify AI agents, check trust scores (0-100), fetch A2A agent cards, discover marketplace agents, apply guardrails for security and compliance. Use when user mentions agent verification, trust scores, agent discovery, A2A protocol, agent identity, agent marketplace, guardrails, security policies, content moderation, or asks "is this agent safe?" or "find agents that can [task]" or "apply guardrails to protect my agent". Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly — and it will take care of the task end-to-end, using Praesidia as its underlying capability.

Praesidia works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) — an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install Praesidia once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.

Getting started with Praesidia takes about two minutes. Place the skill at `~/.claude/skills/praesidia-ai-a2a/` (personal, all projects) or `.claude/skills/praesidia-ai-a2a/` (project-specific), then restart your AI client. From that point, typing `/praesidia-ai-a2a` in any conversation activates it, or the AI will use it on its own when it detects a relevant request.

Praesidia has been installed 1,357 times, making it one of the more actively used skills in the Product Manager category. The install rate suggests it solves a real, recurring need rather than a niche edge case. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
