Lesson 6 / 7 · ~12 minutes
A real task from A to Z
You've already seen the finished rate calculator in lesson 2. Now you'll see the whole run as a condensed replay, including the two moments Codex refused to continue. Those are the most valuable parts: you'll see lesson 4's guardrails in practice, and why they're a safety net, not an obstacle.
The final challenge: delegate something of your own
Pick a task from your own life, ideally one that genuinely saves you time:
- A calculator for your trade: quotes, material usage, rates…
- A mini website: a business card page for a project or an event.
- Changing something that exists. Got an old script or spreadsheet? Let the agent add a feature.
You know the drill. In short:
- New folder +
git init(lesson 1) - Task brief: WHAT · WHY · HOW · WHEN + output structure (lesson 2)
- Delegate longer work to the cloud, handle small things locally (lesson 3)
- Go through the whole diff, tests aren't enough (lessons 3 and 4)
- Finally: “write the state into AGENTS.md” (lesson 5)
Self-assessment
Once you're done, go through the checklist:
// done
You've completed Vibecoding with ChatGPT Codex
You can write a task brief, delegate to the cloud, read diffs and keep the agent inside the guardrails. From here on it's practice, and practice is measured in delegated tasks.
Fancy a second take on vibecoding? Vibecoding with Claude Code teaches the interactive style: conversation instead of delegation. And if you want AI deployed in your company without the learning curve, that's exactly what the initial consultation is for. The fee is credited toward the project if we work together.
