Installation

From Local Folder (Recommended)

1. Clone this repository
2. Open Kiro IDE → Powers panel
3. Click "Import from folder"
4. Select the kiro subdirectory (not the root directory)

Prerequisites

1. Install Codex CLI:

   npm install -g @openai/codex

2. Configure OpenAI API Key (choose one method):

   Method A: Environment variable (recommended)

   export OPENAI_API_KEY="your-api-key"

   Method B: Codex config file

   codex config set api-key your-api-key

Environment Variable Configuration

If your Codex CLI uses environment variables for API key, you need to pass them in the MCP configuration.

After installing this power, modify your ~/.kiro/settings/mcp.json to include the env section:

{
  "powers": {
    "mcpServers": {
      "power-codex-codex": {
        "command": "codex",
        "args": ["mcp-server"],
        "env": {
          "OPENAI_API_KEY": "${OPENAI_API_KEY}"
        }
      }
    }
  }
}

This ensures the OPENAI_API_KEY environment variable is passed to the Codex MCP server.

Usage

Once installed, mention keywords like "codex", "coding", "agent" in your chat to activate this power.
