A short reference lesson on the file types that show up all through the course and everywhere else you'll work with agents. Markdown first, since it's where you'll spend your time, and a word on picking an editor you enjoy (including Flywrite, the one you saw in every demo). Then JSON, HTML, YAML and frontmatter, and scripts, each explained in a minute with what it's for and how much of it you need to touch. We click through the example repos to see each type in place, and close on the point that matters: every file opens in any text editor, and switching tools never means switching your work.
What's covered:
- Markdown: why it's everywhere in agent work, and the marks that make up the language
- Choosing a markdown editor, and a Flywrite coupon for this lesson
- JSON: how programs hand data to each other
- HTML: a whole page in one file, and how it showed up in the course
- YAML and frontmatter, including the block at the top of every skill
- Scripts: files something runs, and why you don't have to write them
- A click-through of each file type in the example repos
- Portability: no export, no migration, no account required to read your own work
