dsh-kernel-codex

DSH runs on one simple idea: everything is a plugin. Models, tools, subagents — plug them together however you like.

So we did exactly that: we turned the OpenAI Codex CLI into a DSH plugin. The codex tool surface you already know — exec_command, write_stdin, apply_patch, request_permissions, web_search, view_image, sleep, update_plan, request_user_input, get_context_remaining, new_context, the multi-agent family (spawn_agent and friends), background-task management (list_tasks / task_output / task_stop), and the file primitives view_file / write_file / edit_file / glob / grep — 30 tools in all, now native DSH tools. Same names, same schemas, same behavior.

The payoff is simple: use the Codex CLI tool surface natively inside DSH — no different from opening Codex itself. Every model stays in the environment it knows best — main agent or subagent, it feels like coming home.

Distilled from @openai/codex 0.147.0 (stable). The 0.148 series is still alpha; handler names are unchanged.

Install

1. Copy the package into your harness profile:

   ~/.dsh/profiles/node_modules/dsh-kernel-codex

2. Add a row inside the planning group of the codex-kernel preset (the preset already disables the colliding DSH rows tool-fs-search and tool-web for you):

   - id: codex-surface
     name: dsh-kernel-codex

   send_message, interrupt_agent, and list_agents share names with DSH's native control tools: if those rows already registered the names, Codex skips them; otherwise the Codex-named tools deliver the same continuable subagents APIs.

Usage

Pick the codex-kernel preset and the codex-kernel model route. The Codex CLI tool surface is then available to whatever model that route runs.
