Phx Intro

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

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

Section Presentation Loop

For each section:

1. 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
2. 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

Iron Laws

1. ONE section at a time — never dump all content at once
2. User controls pace — always offer to stop between sections
3. Clean formatting — use tables and code blocks, not walls of text
4. NEVER skip the user's questions — tutorial is interactive, not a monologue; if the user asks a question mid-section, answer it before continuing

Closing Message

After Section 6 (or when user stops):

You're all set! Try `/phx-plan` with your next feature to see the workflow in action.
Run `/phx-intro --section N` anytime to revisit a specific section.

Notes

• This runs in main conversation context (not a subagent)
• Reference file is readable since skill runs in user's session
• Keep tone welcoming but concise — developers don't want fluff
