DSH Codex Coding: Codex-Style Coding Presets and Workflows for Harness

DSH Codex Coding (dsh-plugin-codex-coding) is a workflow-type Harness plugin maintained by ygzhang-lab, providing Codex Coding presets and delivery contracts. It only takes effect when this preset is selected in a new session, supports three modes (Q&A/Review/Codex), automatic switching of reasoning levels, tools such as apply_patch and coding_context, and includes session-based workflow cards. Installation requires pairing with DSH 0.2.2.x and plugin 0.2.2-rc.1; for Desktop, add the package name, or execute `dsh plugin add` via CLI. The plugin runs with host process privileges; please review the source code and the MIT license before use.
