# Codex CLI

Run Codex CLI in your workspace to access OpenAI's models through the Codex interface, with custom pre/post install scripts. This module integrates with [AgentAPI](https://github.com/coder/agentapi) for Coder Tasks compatibility.

```tf
module "codex" {
source = "registry.coder.com/coder-labs/codex/coder"
version = "1.0.0"
agent_id = coder_agent.example.id
openai_api_key = var.openai_api_key
agentapi_version = "v0.3.2"

Suggested change
agentapi_version = "v0.3.2"
agentapi_version = "v0.3.3"

}
```

## Prerequisites

- You must add the [Coder Login](https://registry.coder.com/modules/coder-login/coder) module to your template

Can we instead use the module inside the module? I know we have the same requirement in other modules too.

@matifali So, instead of the user adding this, we pre-include it in our module ?

Yes. Needs to test though how it works.

- OpenAI API key for Codex access

## Usage Example

- Simple usage Example:

```tf
module "codex" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder-labs/codex/coder"
version = "1.0.0"
agent_id = coder_agent.example.id
openai_api_key = "..."
codex_model = "o4-mini"
install_codex = true
codex_version = "latest"
folder = "/home/coder/project"
codex_system_prompt = "You are a helpful coding assistant. Start every response with `Codex says:`"
}
```

- Example usage with Tasks:

```tf
# This
data "coder_parameter" "ai_prompt" {
type = "string"
name = "AI Prompt"
default = ""
description = "Initial prompt for the Codex CLI"
mutable = true
}

module "coder-login" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/coder-login/coder"
version = "1.0.31"
agent_id = coder_agent.example.id
}

module "codex" {
source = "registry.coder.com/coder-labs/codex/coder"
agent_id = coder_agent.example.id
openai_api_key = "..."
ai_prompt = data.coder_parameter.ai_prompt.value
agentapi_version = "v0.3.2"

}

> **Security Notice**: This module uses the `--dangerously-bypass-approvals-and-sandbox` flag when running Codex CLI. This flag
> bypasses standard permission checks and allows Codex CLI broader access to your system than normally permitted. While
> this enables more functionality, it also means Codex CLI can potentially execute commands with the same privileges as
> the user running it. Use this module _only_ in trusted environments and be aware of the security implications.

## How it Works

- **Install**: The module installs Codex CLI and sets up the environment
- **System Prompt**: If `codex_system_prompt` and `folder` are set, creates the directory (if needed) and writes the prompt to `AGENTS.md`
- **Start**: Launches Codex CLI in the specified directory, wrapped by AgentAPI
- **Environment**: Sets `OPENAI_API_KEY` and `CODEX_MODEL` for the CLI (if variables provided)

## Troubleshooting

- Check installation and startup logs in `~/.codex-module/`
- Ensure your OpenAI API key has access to the specified model

> [!IMPORTANT]
> To use tasks with Codex CLI, ensure you have the `openai_api_key` variable set, and **you create a `coder_parameter` named `"AI Prompt"` and pass its value to the codex module's `ai_prompt` variable**. [Tasks Template Example](https://registry.coder.com/templates/coder-labs/tasks-docker).
> The module automatically configures Codex with your API key and model preferences.

could you test the "skip appending system prompt if already appended" functionality?

const prompt = "This is a system prompt for Codex.";
const { id } = await setup({
moduleVariables: {
codex_system_prompt: prompt,

});
await execModuleScript(id);

await execModuleScript(id);
const resp = await execContainer(id, [
"bash",
"-c",
`cat /home/coder/.codex-module/agentapi-start.log`,
]);
expect(resp.stdout).toContain(`Every step of the way, report tasks to Coder with proper descriptions and statuses. Your task at hand: ${prompt}`);
});

test("start-without-prompt", async () => {
const { id } = await setup();
await execModuleScript(id);
const prompt = await execContainer(id, ["ls", "-l", "/home/coder/AGENTS.md"]);
