The AI Act 50 Skill: making any AI agent a proactive Article 50 compliance agent

The MCP Server gives Claude the tools to certify AI-generated content. But a tool is only useful if the agent knows when to use it.

That’s the gap the AI Act 50 Skill fills.

What is a SKILL.md?

A SKILL.md is an instruction document that tells a language model — Claude, GPT, Gemini, or any LLM running an agentic workflow — when and how to use a specific capability. Think of it as a policy embedded directly into the agent’s reasoning process. Not a manual step. Not a checkbox at the end of a pipeline. A decision embedded at every content distribution point.

The AI Act 50 Skill does one thing: it makes any AI agent evaluate, before publishing or distributing content, whether Article 50 compliance applies — and if it does, certify the content automatically.

The decision tree

The skill works through four questions:

  1. Is this content AI-generated? A post written by Claude, an image from DALL-E, audio from a synthesis model — yes. A human-written email with light AI formatting — probably not.
  2. Is it going to a public or semi-public channel? LinkedIn, a website, an email to external recipients, an API response to end users — yes. An internal Slack note or a draft not yet published — not yet.
  3. What type of content is it? A social media post needs full certification (L1 watermark + L2 C2PA + L3 blockchain). An API response needs at minimum L2. A marketing article needs the full stack.
  4. Which tool to call? certify_content for new content, verify_certificate to confirm existing certificates, detect_watermark to check if content already carries a mark.

The agent resolves all four questions in milliseconds, without human intervention.

Why this matters for agentic pipelines

The EU AI Act Article 50 was written assuming humans are in the loop — a person creates, a person reviews, a person publishes. In 2026, that model describes only a fraction of AI content workflows. Agents generate, format, and distribute content at scale, autonomously, around the clock.

The AI Act 50 Skill is the compliance layer that moves with the agent. It doesn’t slow down the pipeline — it runs inside it.

How to install it

The SKILL.md lives in the vottunio/ai-compliance repository. If you’re using Claude Desktop or Claude Code, place it in your project’s /.claude/ directory alongside your MCP Server configuration. If you’re using Cursor or Windsurf, follow their respective skill loading documentation.

The MCP Server and the SKILL.md are designed to work together. The server provides the capability. The skill provides the intelligence.
