Overview

Runtime prompt layer for Codex coding agent runs.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

Use Codex for coding tasks when the Coding Agent Harness context selects it. Follow that context's command template and run it through Nakama's bash tool with codingAgent: true, cwd set to the target project, and a task-appropriate timeoutMs.

Prerequisites

Install Codex on the Nakama host if needed: npm install -g @openai/codex.
Authenticate with codex login or configure OPENAI_API_KEY. A missing API key does not imply that CLI login is missing.
Check codex --version and codex login status when installation or auth is uncertain.

One-shot coding

codex exec is non-interactive and works with Nakama's pipe-based bash tool. Do not request a PTY or use an interactive codex session there.

codex --ask-for-approval never exec --skip-git-repo-check --sandbox workspace-write --color never 'Make the requested change, run targeted checks, and summarize the result.'

--ask-for-approval is a top-level option and must come before exec. --skip-git-repo-check permits scratch work outside a git repository; it does not replace setting cwd to the right project for repo changes. Put the task prompt in one shell argument and quote it safely.

If workspace sandbox setup fails on the host, report the error. Use --sandbox danger-full-access only when the operator has authorized running Codex with the host process's full filesystem access.

Reviews

From the target repository, use codex review --base origin/main for branch changes or codex review --uncommitted for local edits. Keep review work read-only unless the user asked for fixes.

After the run

Check the bash exit code and timeout result. Verify changed files and targeted tests before reporting success. For implementation tasks, follow the coding-agent skill's branch, commit, push, and PR instructions unless the user requested local-only work.

Use Codex for coding tasks when the Coding Agent Harness context selects it. Follow that context's command template and run it through Nakama's `bash` tool with `codingAgent: true`, `cwd` set to the target project, and a task-appropriate `timeoutMs`.

## Prerequisites

- Install Codex on the Nakama host if needed: `npm install -g @openai/codex`.
- Authenticate with `codex login` or configure `OPENAI_API_KEY`. A missing API key does not imply that CLI login is missing.
- Check `codex --version` and `codex login status` when installation or auth is uncertain.

## One-shot coding

`codex exec` is non-interactive and works with Nakama's pipe-based `bash` tool. Do not request a PTY or use an interactive `codex` session there.

```bash
codex --ask-for-approval never exec --skip-git-repo-check --sandbox workspace-write --color never 'Make the requested change, run targeted checks, and summarize the result.'
```

`--ask-for-approval` is a **top-level** option and must come before `exec`. `--skip-git-repo-check` permits scratch work outside a git repository; it does not replace setting `cwd` to the right project for repo changes. Put the task prompt in one shell argument and quote it safely.

If workspace sandbox setup fails on the host, report the error. Use `--sandbox danger-full-access` only when the operator has authorized running Codex with the host process's full filesystem access.

## Reviews

From the target repository, use `codex review --base origin/main` for branch changes or `codex review --uncommitted` for local edits. Keep review work read-only unless the user asked for fixes.

## After the run

Check the `bash` exit code and timeout result. Verify changed files and targeted tests before reporting success. For implementation tasks, follow the `coding-agent` skill's branch, commit, push, and PR instructions unless the user requested local-only work.

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.

Runtime prompt layer for Codex coding agent runs.

Price unconfirmed★ 448 GitHub starsRegistry updated · Sep 27, 2026agent-skill

Overview

Runtime prompt layer for Codex coding agent runs.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

Prerequisites

Install Codex on the Nakama host if needed: npm install -g @openai/codex.
Authenticate with codex login or configure OPENAI_API_KEY. A missing API key does not imply that CLI login is missing.
Check codex --version and codex login status when installation or auth is uncertain.

One-shot coding

codex exec is non-interactive and works with Nakama's pipe-based bash tool. Do not request a PTY or use an interactive codex session there.

codex --ask-for-approval never exec --skip-git-repo-check --sandbox workspace-write --color never 'Make the requested change, run targeted checks, and summarize the result.'

If workspace sandbox setup fails on the host, report the error. Use --sandbox danger-full-access only when the operator has authorized running Codex with the host process's full filesystem access.

Reviews

From the target repository, use codex review --base origin/main for branch changes or codex review --uncommitted for local edits. Keep review work read-only unless the user asked for fixes.

## Prerequisites

## One-shot coding

`codex exec` is non-interactive and works with Nakama's pipe-based `bash` tool. Do not request a PTY or use an interactive `codex` session there.

```bash
codex --ask-for-approval never exec --skip-git-repo-check --sandbox workspace-write --color never 'Make the requested change, run targeted checks, and summarize the result.'
```

If workspace sandbox setup fails on the host, report the error. Use `--sandbox danger-full-access` only when the operator has authorized running Codex with the host process's full filesystem access.

## Reviews

From the target repository, use `codex review --base origin/main` for branch changes or `codex review --uncommitted` for local edits. Keep review work read-only unless the user asked for fixes.

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
