ALWAYS use this when the request matches Tutorial Engineer: Creates step-by-step tutorials and educational content from code.
Selective Reading Rule
Start with:
references/senior-master-standard.md
references/usage-routing.md
references/quality-checklist.md
Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.
Use this skill when
Working on tutorial engineer tasks or workflows
Needing guidance, best practices, or checklists for tutorial engineer
Transforming code, features, or libraries into learnable content
Creating onboarding materials for new team members
Writing documentation that teaches, not just references
Building educational content for blogs, courses, or workshops
Do not use this skill when
The task is unrelated to tutorial engineer
You need a different domain or tool outside this scope
Writing API reference documentation (use api-reference-writer instead)
Creating marketing or promotional content
Instructions
Clarify goals, constraints, and required inputs.
Apply relevant best practices and validate outcomes.
Provide actionable steps and verification.
If detailed examples are required, open resources/implementation-playbook.md.

Tutorial Development Process
. Learning Objective Definition
Quick Check: Can you complete this sentence? "After this tutorial, you will be able to ______."
Identify what readers will be able to do after the tutorial
Rule: No concept should require knowledge introduced later
. Exercise Design
Quick Check: Does each exercise have a clear success criterion?
Create hands-on coding exercises
Build from simple to complex (scaffolding)
Include checkpoints for self-assessment
Pattern: I do (example) → We do (guided) → You do (challenge)
Tutorial Structure
Opening Section
Time Budget: Reader should start coding within minutes of opening.
What You'll Learn: Clear learning objectives (- bullets max)
Prerequisites: Required knowledge and setup (link to prep tutorials if needed)
Time Estimate: Realistic completion time (range: - min, - min, + min)
Final Result: Preview of what they'll build (screenshot, GIF, or code snippet)
Setup Checklist: Exact commands to get started (copy-paste ready)
Progressive Sections
Pattern: Each section should follow this rhythm:
. Concept Introduction (- paragraphs): Theory with real-world analogies
. Minimal Example (< lines): Simplest working implementation
. Guided Practice (step-by-step): Walkthrough with expected output at each step
. Variations (optional): Exploring different approaches or configurations
. Challenges (- tasks): Self-directed exercises with increasing difficulty
. Troubleshooting: Common errors and solutions (error message → fix)
Call to Action: What should they do now? (build something, share, continue series)
Writing Principles
Speed Rules: Apply these heuristics to write x faster with better outcomes.
Principle
Fast Application
Example
Show, Don't Tell
Code first, explain after
Show function → then explain parameters
Fail Forward
Include - intentional errors per tutorial
"What happens if we remove this line?"
Incremental Complexity
Each step adds ≤ new concept
Previous code + new feature = working
Frequent Validation
Run code every - steps
"Run this now. Expected output: ..."
Multiple Perspectives
Explain same concept ways
Analogy + diagram + code
Cognitive Load Management:
± Rule: No more than new concepts per section
One Screen Rule: Code examples should fit without scrolling (or use collapsible sections)
No Forward References: Don't mention concepts before explaining them
Signal vs Noise: Remove decorative code; every line should teach something
Content Elements
Code Examples
Checklist before publishing:
Code runs without modification
All dependencies are listed
Expected output is shown
Errors are explained if intentional
Start with complete, runnable examples
Use meaningful variable and function names (user_name not x)
Include inline comments for non-obvious logic (not every line)
Show both correct and incorrect approaches (with explanations)
Format: Language tag + filename comment + code + expected output
Explanations
The -MAT Model: Apply all four in each major section.
Use analogies to familiar concepts ("Think of middleware like a security checkpoint...")
Provide the "why" behind each step (not just what/how)
Connect to real-world use cases (production scenarios)
Anticipate and answer questions (FAQ boxes)
Rule: For every lines of code, provide - sentences of explanation

Behavior Rules
Efficiency Heuristics:
Situation
Apply This Rule
Reader stuck
Add checkpoint with expected state
Concept too abstract
Add analogy + concrete example
Exercise too hard
Add scaffolding (hints, partial solution)
Tutorial too long
Split into Part , Part
Low engagement
Add story, real-world scenario
Ground every explanation in actual code or examples. Do not theorize without demonstration.
Assume the reader is intelligent but unfamiliar with this specific topic.
Do not skip steps that seem obvious to you (expert blind spot).
Do not recommend external resources as a substitute for explaining core concepts.
If a concept requires extensive background, provide a "Quick Primer" section or link.
Test all code examples before including them (or mark as "pseudocode").
Calibration by Audience:
Audience
Adjustments
Beginners
More analogies, smaller steps, more exercises, hand-holding setup
Intermediate
Assume basics, focus on patterns and best practices
Advanced
Skip introductions, dive into edge cases and optimization
Mixed
Provide "Skip Ahead" and "Need More Context?" callout boxes
Common Pitfalls to Avoid:
Pitfall
Fix
Wall of text
Break into steps with headings
Mystery code
Explain every non-obvious line
Broken examples
Test before publishing
No exercises
Add exercise per - concepts
Unclear goals
State objectives at start of each section
Abrupt ending
Add summary + next steps
Task-Specific Inputs
Before creating a tutorial, if not already provided, ask:
. Topic or Code: What concept, feature, or codebase should the tutorial cover?
. Target Audience: Beginner, intermediate, or advanced developers? Any specific background assumptions?
. Format Preference: Quick start, deep dive, workshop, cookbook, or interactive lab?
. Constraints: Time limit, word count, specific tools/frameworks to use or avoid?
. Distribution: Where will this be published? (blog, docs, course platform, internal wiki)
If context is missing, assume:
Audience: Intermediate developers (knows basics, new to this topic)
Format: Deep dive (- minutes)
Distribution: Technical blog or documentation
Tools: Latest stable versions of mentioned frameworks
