Agent Surface Auditor checks to ensure your site is ready for Agents Scans visit (must be)

The Problem

Most discussions about optimizing for agents sound abstract, but in practice agent‑facing failures are plain engineering issues:

• One machine‑readable document links to one canonical path, while another links to an older or duplicated public path.
• Sitemaps forget important execution docs.
• OpenAPI files are reachable but buried behind inconsistent references.
• Instructions are written for humans, not for machine execution.

Introducing the Agent Surface Auditor

We built a standalone Agent Surface Auditor to detect these issues automatically.

What It Checks

• Discovery files such as robots.txt, sitemap.xml, llms.txt, and llms-full.txt.
• Project‑specific docs defined by config (e.g., execution docs or OpenAPI files).
• Execution surfaces for MCP, API docs, OpenAPI, or CLI.
• Content‑quality signals: heading structure, readability, and semantic HTML.
• Canonical drift between repository state and public output.

Common Issues Detected

• Stale public links.
• Multiple canonical entry points.
• Machine‑readable docs missing from sitemap/index layers.
• Content that is technically accessible but too noisy for an agent to use efficiently.

Provider Choices

The auditor lets you select the fetching provider explicitly:

• direct-fetch
• browserbase
• cloudflare
• auto (quality‑aware fallback)

Choosing the right provider matters because not every site needs browser rendering, and some providers succeed where others do not.

Installation & Usage

Quick Install Path

npx agent-surface-auditor run --mode url --url https://example.com --provider auto

Alternative Installation

npx openskills install Citedy/agent-surface-auditor

Key Takeaways

Agent‑readiness goes beyond publishing llms.txt. It requires a coherent execution surface:

• One canonical path.
• One clean machine‑readable layer.
• One obvious next action.

This is simultaneously a docs problem, an infrastructure problem, and a product‑reliability problem.

Fact Anchors

• Agents benefit from a stable discovery layer and canonical machine‑readable links.
• Markdown and plain text reduce presentation noise for high‑value technical content.
• MCP, APIs, and CLI workflows are stronger action targets than generic landing pages.
• Public skills should be installable through a direct command or registry flow, not hidden behind manual setup.
• Cross‑file link drift between discovery files, sitemap entries, and execution docs is a concrete failure mode.
• Teams should audit agent‑facing surfaces continuously, not treat them as one‑off marketing assets.
