What it is

GitHub Copilot started as autocomplete and is now a full agent: it plans, edits across files, and runs tasks from inside VS Code, JetBrains, the new Copilot CLI, the Copilot Desktop App, and on GitHub.com itself.

It is a genuinely affordable on-ramp — the paid plans are cheap by agent standards and the tooling is polished — and you can point it at models from multiple providers (a BYOK-style choice), so you are not locked to one brain.

The catch for a naira budget: on 2026-06-01 Copilot moved to usage-based billing. Beyond your plan's included allowance, premium requests are metered, so heavy agent use can quietly run up a USD bill. Treat the meter as the thing to watch.

Install & set up

1. Subscribe

Pick a Copilot plan on GitHub (there is a free tier with a small monthly allowance to try it). Students and many open-source maintainers qualify for free access.

2. Install in your editor

Add the Copilot extension to VS Code (or JetBrains) and sign in with your GitHub account.

code --install-extension GitHub.copilot

3. Install the Copilot CLI

Run the agent from your terminal — handy for headless tasks and scripts.

npm install -g @github/copilot

4. Or get the Desktop App

Copilot now ships a standalone Desktop App for running agent sessions outside the editor. Download it from the official site.

5. Watch the meter

Open your GitHub billing page and set a spending limit before you run big agent jobs. Usage-based billing (since 2026-06-01) means premium requests past your allowance cost USD.

From install to your first verified proof

The tool drafts; you stay accountable. Here is the path from a fresh install to a proof you can defend.

1Pick one small real feature and state the user, the workflow, and the success condition before you ask Copilot for anything.

2Let the agent draft it, then read and approve every change — the same Inspect discipline you would use anywhere.

3Run it, test on mobile, and fix one bug yourself so you can explain it. Check your request meter while you are at it.

4Deploy and log the result at /proof with your live URL, repo, and Explain.

The proof tie: Copilot is a cheap way to start, not a way to skip the work. Watch the meter, review every diff, deploy, and log the proof at /proof.
