# Complete Codex Builder Bundle Preview

This preview gives you a sample of what is included in the full bundle:

- Codex Beginner Guide
- Advanced Codex Field Guide
- Codex Template Vault

The full bundle is designed for beginners, freelancers, and entrepreneurs who want to use Codex to build, debug, automate, and package practical AI-assisted software services.

This is an independent practical guide. It is not affiliated with, sponsored by, or endorsed by OpenAI.

# Sample 1: Beginner Guide

## The Beginner Prompt Formula

Use this structure when you ask Codex to build or change something:

1. **Goal** - what you want done
2. **Context** - what project, files, or audience matters
3. **Constraints** - what Codex should or should not change
4. **Done-when criteria** - how you will know the task is complete

### Example Prompt

```text
Build a simple landing page for a local cleaning business.

Use HTML, CSS, and JavaScript only.
Keep the design mobile-friendly.

Done when the page has a hero section, services section,
pricing section, contact form, and clear call-to-action.
```

## Beginner Safety Checklist

- Review changes before accepting them.
- Ask Codex to explain anything you do not understand.
- Do not paste passwords, private keys, or sensitive client data.
- Keep a backup before major changes.
- Test the project before publishing or delivering it.

# Sample 2: Advanced Field Guide

## The Advanced Codex Prompt Formula

Use this structure for serious project work:

1. **Role** - what kind of help you want
2. **Goal** - the exact business or product outcome
3. **Project context** - the app, repo, framework, and current state
4. **Files or areas to inspect** - where Codex should look first
5. **Constraints** - limits, style rules, dependencies, and risk boundaries
6. **Output format** - code, plan, checklist, diff summary, or review
7. **Done-when criteria** - the exact finish line
8. **Risk limits** - what Codex should avoid

### Example Prompt

```text
Act as a senior code reviewer.

Review this project for bugs, risky assumptions, missing tests,
and deployment blockers.

Focus on authentication, payment handling, form validation,
environment variables, and edge cases.

Do not rewrite code yet. Return findings first, ordered by severity,
with file references and suggested fixes.
```
