Issue
A ticket on GitHub in which someone describes a problem or an idea. Each one has a number, for example #142.
How it appears in the course
You can point directly at something from a server with @, for example @github:issue://231.
Install the gh program (the GitHub CLI, GitHub’s tool for the terminal). That way Claude can also work with issues (tickets with problems or ideas) and with PRs.
The example below fixes an “issue” (a problem reported in the project, on the GitHub website, where teams keep their code). In the text, $ARGUMENTS is an empty spot that gets filled in automatically with what you write after the command.
