It seems the future of agentic platforms will be more deterministic by leveraging traditional automation techniques. In this case Claude Code is adding support for lifecycle hooks, which allow you to write shell commands to ensure certain actions always happen. docs.anthropic.com/en/docs/clau...

Microsoft laid off this legend. Catch him while you can ….

hire this legend

Hire Mark! He is not only a great advocate and speaker, but a wonderful person.

Just got caught up in the latest round of terminations from Microsoft. If anyone needs a "batteries included" advocate who really knows code, AI, and real production concerns + solutions, ping me! Ready to make great things happen for you. Onward and upward!
