My Experience with GitHub Copilot CLI

I kicked off the project with a straightforward prompt: build a GitHub CLI extension in Go that surfaces the latest updates from the GitHub Changelog. Within minutes, I had a working prototype that fetched real data and did exactly what I asked. That "time-to-something-useful" was genuinely impressive.

Where things fell a bit short initially was polish - layout, output formatting, and some of the CLI ergonomics I care about. That wasn’t a limitation of Copilot so much as a reflection of how broad my early prompts were. I asked for something functional, and that’s exactly what I got.

From there, I made use of the /delegate command to kick off other agent tasks resulting in a PR for each bit of visual polish and features like:

• Adding relative dates and an ID column
• Adding a view command to view changelog entries individually in terminal
• Adding an open command to view changelog entries in a browser

What I learned / what was reinforced

• Copilot is incredibly good at getting you to "something useful" fast
• Quality of output maps directly to quality of prompts
• Treating Copilot like a junior collaborator (not a magic wand) works well
• Agent-style delegation maps surprisingly well to small, reviewable PRs

If you live in the terminal and want to stay current with GitHub updates, give it a try:

gh extension install leereilly/gh-changelog
gh changelog
