Docs Skill (clean)
You could use curl to explore the web, check response codes, or download the occasional file, and it is a perfectly ordinary tool that ships on almost every machine you are likely to work on these days, which is one reason it comes up so often in general documentation. Anyway, none of that is what this paragraph is about: ~/documents/example.json is just used here as an example filename, purely illustrative, and nothing in this document executes it, reads it, or does anything else with it at all.
There is no code block anywhere in this skill.
