Addy Osmani: Agentic Engine Optimization (AEO) — Structure Your Docs So AI Agents Can Actually Use Them: llms.txt, Token Budgets, skill.md, and Agent Analytics

Addy Osmani·high signal

Osmani introduces AEO as a new discipline: structuring technical content for AI coding agent consumption. Key practices: create llms.txt at your domain root as an agent sitemap (under 5K tokens), track token counts as a first-class metric (quickstarts <15K, API refs <25K), write skill.md files declaring service capabilities, and segment AI referral traffic. A 4-week implementation roadmap: Week 1 audit robots.txt and add llms.txt, Week 2 surface token counts, Week 3 create skill.md for top APIs, Week 4 monitor agent behavior. Emerging standards include AGENTS.md and agent-permissions.json.
