markdown-novel-viewer（Markdown novel viewer 搜索）

[IMPORTANT] Use TaskCreate to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

Quick Summary

Goal: Background HTTP server that renders markdown files with a calm, book-like reading UI and browses directories.

Workflow:

1. Start Server — Point at a markdown file or directory with CLI options
2. View Content — Novel-themed reader (serif fonts, warm colors) or directory browser
3. Navigate Plans — Auto-detects plan structures with sidebar, phase status, keyboard shortcuts

Key Rules:

• Requires npm install before first use (marked, highlight.js, gray-matter)
• Use /preview slash command for quick access
• Supports background mode, remote access via --host 0.0.0.0

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

⚠️ Installation Required

This skill requires npm dependencies. Run one of the following:

# Option 1: Install via ClaudeKit CLI (recommended)
ck init  # Runs install.sh which handles all skills

# Option 2: Manual installation
cd .claude/skills/markdown-novel-viewer
npm install

Dependencies: marked, highlight.js, gray-matter

Without installation, you'll get Error 500: Error rendering markdown.

Purpose

Universal viewer - pass ANY path and view it:

• Markdown files → novel-reader UI with serif fonts, warm theme
• Directories → file listing browser with clickable links

Quick Start

# View a markdown file
node .claude/skills/markdown-novel-viewer/scripts/server.cjs \
  --file ./plans/my-plan/plan.md \
  --open

  --dir ./plans \
  --host 0.0.0.0 \
  --open

# Background mode
node .claude/skills/markdown-novel-viewer/scripts/server.cjs \
  --file ./README.md \
  --background

# Stop all running servers
node $HOME/.claude/skills/markdown-novel-viewer/scripts/server.cjs --stop

Slash Command

Use /preview for quick access:

/preview plans/my-plan/plan.md    # View markdown file
/preview plans/                   # Browse directory
/preview --stop                   # Stop server

HTTP Routes

Dependencies

• Node.js built-in: http, fs, path, net
• npm: marked, highlight.js, gray-matter (installed via npm install)

Customization

Theme Colors (CSS Variables)

Light mode variables in assets/novel-theme.css:

--bg-primary: #faf8f3; /* Warm cream */
--accent: #8b4513; /* Saddle brown */

Dark mode:

--bg-primary: #1a1a1a; /* Near black */
--accent: #d4a574; /* Warm gold */

Content Width

--content-width: 720px;

Remote Access

To access from another device on your network:

# Start with 0.0.0.0 to bind to all interfaces
node server.cjs --file ./README.md --host 0.0.0.0 --port 3456

When using --host 0.0.0.0, the server auto-detects your local network IP and includes it in the output:

{
    "success": true,
    "url": "http://localhost:3456/view?file=...",
    "networkUrl": "http://192.168.2.75:3456/view?file=...",
    "port": 3456
}

Use networkUrl to access from other devices on the same network.

Troubleshooting

Port in use: Server auto-increments to next available port (3456-3500)

Images not loading: Ensure image paths are relative to markdown file

Server won't stop: Check /tmp/md-novel-viewer-*.pid for stale PID files

Remote access denied: Use --host 0.0.0.0 to bind to all interfaces

Closing Reminders

• IMPORTANT MUST ATTENTION break work into small todo tasks using TaskCreate BEFORE starting
• IMPORTANT MUST ATTENTION search codebase for 3+ similar patterns before creating new code
• IMPORTANT MUST ATTENTION cite file:line evidence for every claim (confidence >80% to act)
• IMPORTANT MUST ATTENTION add a final review todo task to verify work quality
