The Agent Tooling Layer Is Taking Shape: Browsers, Pipelines, and Permission Systems

A cluster of new tools dropping this week reveals a maturing stack for autonomous AI agents: headless browser control, iOS CI/CD pipelines, sub-agent permission tokens, and a framework that extends Claude Code into general-purpose use. The practical implication is that the boring infrastructure work for reliable agents is finally happening.
