Stop Getting Good at Protocols. Get Good at Agent Experience.

Summary

The article argues against focusing on specific AI agent protocols, such as MCP or AI Skills, advocating instead for "Agent Experience" (AX). AX is defined as the discipline of systematically improving how AI agents discover, understand, and interact with systems. The author highlights that protocols are transient tools, citing the rapid obsolescence of MCP in late 2025 and early 2026 in favor of AI Skills and CLI. A 2026 Queen's University study found 97.1% of tool descriptions across 103 MCP servers contained quality issues, with 56% failing to state their purpose clearly, indicating experience design, not protocol, was the problem. AX extends User Experience (UX), Developer Experience (DX), and Customer Experience (CX) to encompass agent interactions, emphasizing that poor agent experience can lead to silent customer churn. The article outlines a five-step AX practice: auditing customer agents, identifying delegated use cases, verifying interaction experiences, continuous improvement, and automating validation with tools like AXIS.

Key takeaway

For AI Architects or Directors of AI/ML building agent-facing systems, prioritize developing an Agent Experience (AX) discipline over mastering specific protocols. Your strategy should center on how agents discover, understand, and interact with your services, as protocols like MCP or AI Skills are transient. Invest in auditing agent behavior and systematically improving interaction quality to prevent silent customer churn and ensure long-term adaptability. This approach builds a resilient foundation for future agentic AI integrations.

Key insights

Agent Experience (AX) is a critical discipline for designing how AI agents interact with systems, transcending specific protocols.

Principles

• Protocols are transient tools, not strategic foundations.
• Focus on agent interaction design, not just protocol implementation.
• Poor agent experience leads to silent customer churn.

Method

An AX practice involves auditing customer agents, identifying delegated use cases, verifying interaction experiences, continuous improvement, and automating validation to prevent regressions.

In practice

• Analyze traffic logs to identify agent usage.
• Prioritize agent-facing interfaces by value.
• Use tools like AXIS for automated AX validation.
