Addy Osmani
Google Chrome engineering leader who writes widely read guides on building with AI coding agents
An engineering leader on Google's Chrome team and a long-standing writer about web performance and developer tooling. His posts on AI-assisted engineering are where many developers first meet the idea of an agent harness, and he points readers to Viv Trivedy's “Anatomy of an Agent Harness” as the clearest derivation of the term.
