Agentic Engineering Expands into Persistent Runtimes and Governed Platforms

Agent development is spreading into governed runtimes, enterprise connectors, MCP access, repository-integrated skills, and human approval boundaries. Microsoft's MXC runtime, Google's Gemini enterprise agent, AWS Strands Box, GitHub's agent-scale platform work, Microsoft Fabric controls, Prime Agent's reported Rust rewrite, and Anthropic's agent-evaluation incident underscore both infrastructure momentum and unresolved reliability, isolation, portability, and cost-attribution problems.
