chapter-checkbox-integration

A set of rules for adding a clickable progress checkbox to each tutorial chapter. It uses a Vue component to let readers mark chapters complete or complete them by scrolling to the end.

In plain words
What is it for?
Use it when building tutorial or documentation series with chapter-by-chapter progress tracking. It covers manual completion, scroll-based completion, local saving, feedback, mobile layouts, dark mode, and accessibility.
Why use it?
It gives readers a visible way to track which chapters they have finished, with progress saved in the browser between visits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

chapter-checkbox-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Chapter Checkbox Integration Guide

This rule provides guidelines for integrating the ChapterCheckbox Vue component into tutorial chapters to enable reader progress tracking.

Overview

The ChapterCheckbox component allows readers to:

  • Mark chapters as complete with a single click
  • Auto-complete chapters by scrolling to the bottom
  • Track progress locally (saved in browser localStorage)
  • See visual feedback with animations and confirmations

Component Features

ChapterCheckbox.vue (docs/.vitepress/theme/components/ChapterCheckbox.vue)

Purpose: Provides an interactive progress tracking component for each chapter

Key Features:

  • Manual completion: Click checkbox to mark chapter complete
  • Auto-completion: Chapter auto-marks when scrolled to bottom
  • Local storage: Progress persists across sessions
  • Visual feedback: Animations, icons, and confirmation messages
  • Responsive design: Works on desktop, tablet, and mobile
  • Dark mode support: Styled for both light and dark themes
  • Accessibility: Proper ARIA labels and semantic HTML

Props

interface ChapterCheckboxProps {
  seriesId: string        // Series identifier (e.g., "php-basics")
  chapterId: string       // Chapter identifier (e.g., "01")
  label?: string          // Custom label (default: "Mark this chapter as complete")
}

Component Behavior

Manual Completion
  1. User clicks checkbox
  2. State updates and saves to localStorage
  3. Confirmation message displays for 2 seconds
  4. Icon changes from book to trophy
Auto-Completion
  1. User scrolls component into view (95% visible)
  2. System waits 1.5 seconds to confirm intentional viewing
  3. If still in view, auto-marks as complete
  4. Celebration animation plays
  5. Confirmation shows "🎉 Chapter auto-completed!"
  6. Progress saved to localStorage
Visual States

Uncompleted:

  • Book icon in teal circle
  • Pulse border animation
  • Hover effect on interaction
  • Hint: "Check the box when you've finished reading..."

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
