Build this lesson inside Codex

Open the repo in Codex, let it inspect the files, then paste the prompt. Ask it to edit only the smallest set of files and verify before you deploy.

Before Codex
1. Open the project in Codex.
2. Confirm .env.local exists locally and is ignored by Git.
3. Open README.md and package.json so Codex can orient itself.
4. Do not paste private keys into the prompt.
Paste this prompt
Inspect this repo for the Prompting, Context, and Structured Outputs build.

Outcome:
Write prompts that produce predictable outputs and can be tested before you wire them into real workflows.

Tools:
OpenAI, Claude, Codex, Context7, TypeScript, Supabase, GitHub

Explain the files a beginner needs to understand before editing:
README.md, package.json, src, public, scripts, .env.local, and any Supabase files.

Then implement the smallest safe version, list required env names, run the build or focused tests, fix failures, and summarize changed files.
