Tech Tutorial Writer

Tech Tutorial Writer — Skill Overview

This skill is a structured writing system for producing high-quality, publish-ready technical tutorials. Every article it generates is designed to be dropped directly into a blog, developer community, or newsletter with minimal editing.

Core Purpose

The skill generates technical tutorials that guide readers through a three-tier learning progression:

Before writing anything, the skill confirms which tier the article belongs to — because each tier has a completely different writing strategy.

Article Structure (Required Sections)

Every tutorial follows this skeleton:

1. Hook

Opens with a relatable real-world pain point. The reader should think "that's exactly my problem." Then previews what they'll gain and how long it takes.

2. Mental Model

Uses everyday analogies to explain abstract concepts before touching any code. Supports ASCII diagrams or Mermaid charts for visualization. No jargon without an explanation.

3. Environment Setup

Lists exact dependency versions, provides a copy-paste initialization command, and pre-warns about common setup pitfalls.

4. Core Content

Depth varies by tier:

• Beginner: Every step has full runnable code + line-by-line breakdown + "what you see now" descriptions
• Intermediate: Wrong approach shown first, then correct approach (contrast format), with supporting performance data
• Advanced: Source code dives, architectural evolution (v1 → v2 → v3), real production incident examples

5. Hands-on Project

Every article must include one complete, runnable demo. Code has inline comments on every key line. Project structure is shown explicitly.

6. FAQ

3–5 high-frequency questions in a consistent format with code examples in the answers.

7. Summary + Next Steps

Bullet-point recap of what was learned, a clear "what to study next" path, and 2–3 curated resources.

Code Quality Standards

All generated code must:

• Run without hidden dependencies
• Include error handling (try/catch, error boundaries, etc.)
• Follow the latest best practices for that language/framework
• Clearly flag any deprecated APIs
• Include TypeScript types for front-end tutorials

Output Format

Each generated article comes with a metadata block followed by the full article body:

Platform Formatting Rules

The skill adapts its output style depending on the target platform:

WeChat Official Account

• Title under 15 Chinese characters, must use a number or question to create curiosity
• First 100 characters must hook the reader (WeChat collapses the preview)
• Paragraphs capped at 5 lines, heavy use of short sentences
• Ends with an engagement prompt ("What problems have you run into? Drop a comment!")

Juejin (Developer Community)

• Longer, keyword-rich titles for SEO
• Uses Juejin-specific Markdown features: :::tip, :::warning, :::danger callout blocks
• Comparison tables for alternative approaches
• 3,000–8,000 words for intermediate/advanced articles

Domains Covered

The skill has pre-mapped learning progressions for:

• Frontend: HTML/CSS basics → component patterns & state management → micro-frontends & compiler internals
• Backend: REST APIs & auth → caching, queues, distributed systems → high-concurrency architecture & SRE
• Algorithms: Arrays/stacks/queues → dynamic programming & graph algorithms → system design & large-scale data
• AI/ML: Python basics & API calls → Prompt Engineering, fine-tuning, RAG → distributed training, inference optimization, MLOps

What Makes This Different from Just "Write a Tutorial"

The skill is modeled on patterns from the highest-performing tutorials on freeCodeCamp, roadmap.sh, Juejin, and top WeChat tech accounts. The key principles it enforces:
