Audit a documentation site for agent-friendliness: discovery, markdown delivery, crawlability, semantic structure, machine-readable surfaces, and content legibility. Use when asked to assess docs.docker.com or any docs site for AI/agent readiness, produce a scored report, compare with external scanners, or generate a remediation list. Triggers on: "audit docs for agent readiness", "how agent-friendly is docs.docker.com", "score our docs for AI agents", "review llms.txt / markdown / crawlability", "create an agent-readiness remediation plan".
