AI coding agents have reached a maturity threshold as of December 2025, fundamentally changing software development workflows. Claude Code and alternatives like OpenCode enable developers to work primarily in natural language, running multiple parallel agent sessions with varying levels of automation. Key workflows include Boris Cherny's multi-session approach with Plan Mode and verification loops, Steve Yegge's Gas Town orchestration system for 20-30 parallel agents, and Geoffrey Huntley's simple Ralph bash loop technique. Anthropic recently blocked third-party tools from using subscription tokens, sparking community backlash. The shift moves developers from imperative coding to declarative success criteria, with experienced practitioners like Andrej Karpathy noting they now code 80% through agents and Peter Steinberger claiming he no longer reads generated code.
