Walkthrough

Explain the code in one pass, from the start of the story to the end. A snippet typed from memory is a miss. Commentary, then a command that prints the file, then the output that command produced.

Pass

1. Read, then plan. Read the source. Plan one order a reader can follow from beginning to end, starting at the foundation or the entry point and moving outward. If the user named a file or an area, stay inside it.

2. Learn the tool. Run uvx showboat --help and use what it prints.

3. Write walkthrough.md at the repo root. If that file already exists, ask before replacing it. Create it with uvx showboat init.

4. Alternate notes and printed code. Commentary goes in with uvx showboat note. Every snippet is a uvx showboat exec of sed, grep, cat, find, or wc that prints the bytes on disk. A hand-copied snippet does not go in the note.

5. Fix a bad command in the document. If an exec fails or prints the wrong lines, uvx showboat pop that entry and run the corrected command.

6. Check. Run uvx showboat verify walkthrough.md. In the reply, give the path to the document.
