Bio
Addy Osmani writes on the web platform from the engineering side, performance, developer experience, what the browser is actually doing under the hood. His distinctive turn over the last year has been to translate platform thinking into the AI-native era: when the consumer of your web pages is increasingly an LLM agent rather than a human, the assumptions that govern frontend craft (rendering speed, navigation flow, visual hierarchy) stop being load-bearing in the same way, and a different set of platform affordances start mattering, agent-permissions, llms.txt, capability declarations, token-efficient TL;DRs, copy-as-markdown buttons.
Operating themes
- Operating thesis: the agent reads your page in 1-2 HTTP requests; the human reads it in minutes. The two have different needs and your platform should serve both.
- Agentic Engine Optimization, six-layer access/discovery/capability/format/token/UX stack for agent-first content.
- Web platform pragmatism, design for what the browser actually does, not the abstraction.
- Performance as discipline, the rules don't change in the AI era; the consumers do.
Cards
- Agent-first content has six platform layers, access, discovery, capability, format, token, UX bridge, Six-layer agent-first content audit: access, discovery, capability, format, token, UX bridge [Tier A]
