GitHub Copilot CLI Cheatsheet - gh copilot Full Reference

Copilot CLI is not the same category of tool as an agent like Claude Code; it is closer to a translator for the shell. You ask what an unfamiliar command means and it explains; you state what you want and it proposes something executable. It will not autonomously rewrite your repository, and it does not need to be handed the project - that lightweight, interruptible, one-question-at-a-time shape covers the fragmentary work agents miss: decoding an unfamiliar stack trace, getting a compound pipeline's flags right, or working out what a destructive command would actually affect. The case for installing is equally practical: if you already spend most of your day in a terminal, the cost is one gh extension, and the quality of its command explanations removes a lot of documentation lookup. This sheet covers explaining commands, generating suggestions, aliases and configuration, and integration plus debugging. The one discipline that matters: whatever it generates, especially anything that deletes, modifies or reaches the network, gets explained before it runs.

Tips

The GitHub Copilot CLI has the largest developer base (default in the gh ecosystem) but is "explain/suggest", not an autonomous agent — complementary to Claude Code-style tools.
Always explain after suggest to verify generated commands, especially -t shell that delete/modify or hit the network — understand before running.
Use gh copilot alias to emit aliases into your shell, shortening daily calls from gh copilot suggest.
Prereqs: gh auth login signed in with an active Copilot subscription; install via gh extension install github/gh-copilot if missing.

FAQ

How should I combine suggest and explain?

Generate with suggest, then review the result with explain — that double-check is far safer than running the suggestion directly. explain is especially valuable for anything unfamiliar, so before running a script you inherited from a repository, run gh copilot explain ":(){:|:&};:" to see what it actually does.

Can I pipe gh copilot suggestions straight into the shell?

No. The output is probabilistic — fluent syntax does not mean correct intent, and it is especially risky when deleting, overwriting or changing permissions. Treat it as a draft: read it, replace placeholders, confirm the flags match your environment, then run it yourself. Cross-checking with explain further reduces the risk of misuse.

What do I need before using gh copilot?

Copilot CLI ships as a gh extension, so gh must be installed and authenticated — check with gh auth status. If the extension is missing, install it via gh extension install github/gh-copilot. Afterwards, gh extension list | grep copilot confirms it. Without these prerequisites the copilot subcommand simply is not found.

How do I get more accurate suggestions from gh copilot?

Use -t to state the type explicitly — shell, gh or git — instead of letting it infer from context, e.g. gh copilot suggest -t shell "back up mysql to s3". Describe the goal and environment precisely in the prompt. Follow generation with explain to close the loop.

How do I integrate gh copilot into my shell?

Run gh copilot alias to generate shell alias snippets, source them into the current shell and use short aliases thereafter. Inspect settings with gh copilot config and change one with gh copilot config set <k> <v>. You can also chain explain and suggest with the gh PR and issue workflow for automation.
