Codex

Key features

• EnglishThree DSH agent presets: provider-neutral Codex, adaptive Codex PTC, and Codex Harness Mode.
• The first two use DSH-native tools and advisory controllers.
• Harness Mode maps the Codex-compatible exec_command, write_stdin, apply_patch, and update_plan contract onto DSH while leaving model access, reasoning effort, context capacity, plugins, filesystem, sandbox, and sessions under DSH ownership.
• It does not start Codex CLI/app-server or require a Codex login.
• Hosted Responses search and remote compaction are disabled so requests never bypass the selected DSH provider.
