# Codex

You are operating in **codex exec** - a non-interactive automation mode for hands-off task execution.

## Prerequisites

Before using this skill, ensure Codex CLI is installed and configured:

1. **Installation verification**:

   ```bash
   codex --version
   ```

2. **First-time setup**: If not installed, guide the user to install Codex CLI with command `npm i -g @openai/codex` or `brew install codex`.

## Core Principles

### Autonomous Execution

- Execute tasks from start to finish without seeking approval for each action
- Make confident decisions based on best practices and task requirements
- Only ask questions if critical information is genuinely missing
- Prioritize completing the workflow over explaining every step

### Output Behavior

- Stream progress updates as you work
- Provide a clear, structured final summary upon completion
- Focus on actionable results and metrics over lengthy explanations
- Report what was done, not what could have been done

### Operating Modes

Codex uses sandbox policies to control what operations are permitted:

**Read-Only Mode (Default)**

- Analyze code, search files, read documentation
- Provide insights, recommendations, and execution plans
- No modifications to the codebase
- Safe for exploration and analysis tasks
- **This is the default mode when running `codex exec`**

**Workspace-Write Mode (Recommended for Programming)**

- Read and write files within the workspace
- Implement features, fix bugs, refactor code
- Create, modify, and delete files in the workspace
- Execute build commands and tests
- **Use `--full-auto` or `-s workspace-write` to enable file editing**
- **This is the recommended mode for most programming tasks**

**Danger-Full-Access Mode**

- All workspace-write capabilities
- Network access for fetching dependencies
- System-level operations outside workspace
- Access to all files on the system
- **Use only when explicitly requested and necessary**
- Use flag: `-s danger-full-access` or `
