Plugin Introduction Tutorial

Interactive walkthrough of the Elixir/Phoenix plugin in 6 sections (~5 min).

Arguments

$ARGUMENTS may contain --section N to jump to a specific section (1-6)
No arguments = start from Section 1

Execution Flow

Read references/tutorial-content.md for all section content
Parse $ARGUMENTS for --section N flag (1-6)
If --section N specified, jump directly to that section
Otherwise start from Section 1

Section Presentation Loop

For each section:

Present the section content completely — do NOT abbreviate or summarize. Every paragraph, table, and code block in the reference file must appear in output — as visible response text emitted BEFORE the AskUserQuestion call; content composed only in thinking is invisible to the user
After presenting, use AskUserQuestion with options:
- If sections remain: "Next: [next section title]", "Skip to Cheat Sheet", "Stop here"
- If on final section (6): no question needed, end with closing message

Section Titles

N	Title
1	Welcome
2	Core Workflow Commands
3	Knowledge & Safety Net
4	Hooks & Behavioral Rules
5	Init, Review & Gaps
6	Cheat Sheet & Next Steps

Iron Laws

ONE section at a time — never dump all content at once
