blog: Codex Brain, Claude Harness: Running GPT-6-Astra in Claude Code

I published Codex Brain, Claude Harness: Running GPT-6-Astra in Claude Code, about running Codex models inside Claude Code through a local CLIProxyAPI and six fish functions in my dotfiles. The API key lives only in 1Password, which is what lets the functions sit in a public repo. The post also covers how two agent chains built it across projects, a small auto-approve accident, and what's still missing compared with Claude: artifacts and Claude in Chrome.
