Agentic coding

The V4-Pro banner I saw on the homepage is about agents: stronger agent skills, Responses API, Codex integration, and a note that V4 plugs into Claude Code, OpenClaw, and OpenCode. That is why this use case exists. I did not invent a coding product DeepSeek does not claim.

My own loop: Pro for the ugly ticket, Flash for the boilerplate, Harness when I want the trace on disk. I still read the diff. The model is not the merge button.
