Dev Guide Generator

One topic → complete technical tutorial: Through a structured SOP workflow, transform a technical topic into a comprehensive tutorial covering prerequisites, environment setup, core steps, common error troubleshooting, and advanced topics — all accompanied by a cheatsheet.

Quick Start

The user simply provides a technical topic or operational goal, and the Agent automatically generates a complete tutorial following this workflow:

User: Help me write a Docker beginner's tutorial
Agent: [Outputs complete technical tutorial + Cheatsheet following the SOP workflow]

SOP Workflow

Phase 1: Topic Scoping & Audience Analysis

Goal: Define the tutorial's technical subject, target audience, and scope boundaries.

Steps:

1. Parse the topic: Identify the core technology, operational goals, and expected deliverables from the user's input
2. Ask clarifying questions (up to 4 key questions):

• What is the target audience's technical level? (Complete beginner / Some experience / Experienced developer)
• What operating system will the reader be using? (macOS / Windows / Linux / Any)
• What should the reader be able to do after completing the tutorial? (Specific deliverable)
• Are there any version or tech stack constraints?

1. If the user asks to skip clarification, proceed with these default assumptions:

• Audience: Has basic programming experience but is unfamiliar with the topic technology
• Environment: Cover both macOS and Linux (note Windows differences where necessary)
• Goal: Be able to independently complete a minimal working example

Output: Tutorial metadata summary (topic, audience, objective, scope — no more than 150 words)

Phase 2: Prerequisites

Goal: List all knowledge and tools the reader needs before starting this tutorial, ensuring there are no knowledge gaps.

Steps:

1. Dependency analysis:

• List all technical concepts involved in this tutorial
• For each concept, determine whether it should be "explained within the tutorial" or "assumed as prior knowledge"
• Decision rule: If explaining it would digress more than 200 words from the main topic, classify it as a prerequisite

1. Prerequisites checklist:

• Categorize into "Must know" and "Nice to know" tiers
• Attach a one-line explanation for each: "why you need it"
• Format:

Must know:

• Concept]: Why you need it] (Recommended resource)

Nice to know:

• Concept]: What aspects of the tutorial it relates to]

1. Self-check rules:

• If prerequisites exceed 5 items, consider narrowing the tutorial scope or splitting into a series
• Every prerequisite must have a publicly available learning resource

Output: Tiered prerequisites checklist

Phase 3: Environment Setup

Goal: Provide a reproducible environment configuration path so the reader is fully set up before starting the core steps.

Steps:

1. Environment inventory: List all tools to install/configure with recommended versions

• Format: Tool name Version requirement (e.g., >= x.y) | Purpose
• Clearly distinguish "required" from "optional" installations

1. Installation steps: Provide commands for each operating system

• Precede each command with a one-line explanation of what it does
• Use only officially recommended methods or mainstream package managers
• Format:

macOS: # Install xxx (via Homebrew) brew install xxx

Linux (Ubuntu/Debian): # Install xxx (via apt) sudo apt update && sudo apt install -y xxx

1. Environment verification: Provide a verification command and expected output after each tool installation

• Format:

# Verify installation xxx --version # Expected output: xxx x.y.z

1. Self-check rules:

• All installation commands must come from official documentation or mainstream package managers — no third-party scripts
• Never include real API keys, passwords, tokens, or other sensitive values
• When configuration files are involved, use placeholders (e.g., YOUR_API_KEY) and explain how to obtain the real value

Output: OS-specific installation and configuration guide + verification commands

Phase 4: Core Steps

Goal: Walk the reader through the core operations in a progressive structure, where each step can be independently verified.

Steps:

1. Step planning:

• Break the entire operation into 5–10 steps (each focused on one sub-goal)
• Order steps strictly by dependency
• Each step includes: step number, title, and objective statement

1. Step writing format:

#### Step N: Step Title]

Objective: What state is achieved after this step]

Actions: Code block or operational instructions]

Explanation:

• Line-by-line or section-by-section explanation of key parts]

Verification: What command to run / what result to check to confirm success] Expected output: Specific expected result]

1. Writing guidelines:

• Code blocks must specify the language (e.g., bash, python)
• Placeholders use ALL_CAPS_WITH_UNDERSCORES format (e.g., YOUR_PROJECT_NAME) and are explained on first occurrence
• Each code block should not exceed 30 lines; split and explain in sections if longer
• Use relative file paths; state the project root directory at the beginning
• Every step must end with a verification section

1. Progressive complexity:

• Steps 1–3: Minimal runnable example (Hello World level)
• Middle steps: Gradually introduce real-world features
• Final 1–2 steps: Combine everything into a complete example

Output: Numbered step list, each containing actions + explanation + verification

Phase 5: Troubleshooting

Goal: Anticipate problems the reader may encounter and provide a direct path from error message to solution.

Steps:

1. Error collection: Based on the technical topic, list the 5–8 most common error scenarios

• Sources: Environment misconfiguration, version incompatibilities, permission issues, typos, network problems, etc.

1. Error entry format:

Error N: Error message summary]

Full error message: Actual error output]

Cause: One-sentence explanation of why this error occurs]

Solution: Specific fix commands or steps]

Verify the fix: What to run to confirm the issue is resolved]

1. Writing guidelines:

• Error messages must be real (do not fabricate error messages)
• Solutions must be actionable — avoid vague advice like "check your configuration"
• If an error has multiple possible causes, list them from most to least likely
• For permission-related issues, explain why the permission is needed rather than jumping to sudo or chmod 777

1. Self-check rules:

• Solutions must not include operations that could create security risks (e.g., chmod 777, disabling firewalls)
• Never advise the reader to disable security features to "fix" a problem

Output: Structured troubleshooting table

Phase 6: Advanced Topics

Goal: Point readers who have completed the basics toward next steps, providing a learning path from beginner to advanced.

Steps:

1. Advanced topic recommendations (3–5 directions):

• For each direction, write a short paragraph: what it is, why it's worth learning, and what scenarios it applies to
• Tag the difficulty level: Intermediate / Advanced
• Format:

Direction N: Topic Name] | Difficulty: Intermediate/Advanced]

Short paragraph]

Recommended resources:

• Resource name] (Type: documentation/book/course])

1. Hands-on project suggestions:

• Provide 2–3 small projects the reader can independently complete using what they learned
• Each project includes: project name, one-sentence description, and relevant concepts

1. Best practice tips (3–5 items):

• Key differences between production and tutorial environments
• Security considerations
• Performance optimization directions

Output: Advanced learning roadmap + hands-on project suggestions + best practices

Phase 7: Cheatsheet

Goal: Distill the tutorial's essentials into a one-page quick reference for everyday use.

Steps:

1. Cheatsheet structure:

# Technology Name] Cheatsheet

## Environment Info | Item | Command/Path | |------|--------------| | Install | command | | Version check | command | | Config file location | path |

## Common Commands | Action | Command | Description | |--------|---------|-------------| | xxx | xxx | xxx |

## Common Code Snippets Up to 5 frequently used code snippets, each no more than 10 lines]

## Quick Troubleshooting | Symptom | Possible Cause | Quick Fix | |---------|---------------|-----------| | xxx | xxx | xxx |

1. Writing guidelines:

• Total cheatsheet length should fit on 2 printed A4 pages
• Commands must be complete and ready to copy-paste
• No explanatory prose — only "what to do → how to do it" mappings
• Order items by frequency of use, from most to least common

Output: One-page cheatsheet

Phase 8: Document Assembly & Output

Goal: Assemble the outputs from the previous seven phases into a complete tutorial document.

Tutorial document template:

Flow Control Rules

Interaction Mode Selection

Choose the mode based on the level of detail in the user's input:

| User Input | Mode | Behavior | |------------|------|----------| | Just a technology name (e.g., "Docker tutorial") | Guided mode | Execute Phase 1 questions, wait for answers before continuing | | Specific goal (e.g., "Deploy a Node.js app with Docker") | Semi-auto mode | Ask 1–2 key questions while simultaneously planning the steps | | Detailed description (includes audience, environment, goal) | Full-auto mode | Start output directly from Phase 2 | | User says "just write it / don't ask" | Quick mode | Output the complete tutorial based on default assumptions |

Quality Checklist

Before outputting the final tutorial, check each item:

• ] Prerequisites checklist is complete with no knowledge gaps
• ] Every environment setup command has a verification step
• ] Every core step includes "actions + explanation + verification"
• ] Step dependencies are correct (no step uses a tool that hasn't been installed yet)
• ] At least 5 common errors with specific, actionable solutions
• ] At least 3 advanced directions with resource recommendations
• ] Cheatsheet is self-contained with common commands and troubleshooting info
• ] All code blocks specify the language
• ] No hardcoded keys, tokens, or personal paths
• ] No suggestions that could create security vulnerabilities (e.g., chmod 777)
• ] No dependency on paid APIs or subscription-only tools (unless the tool itself is the tutorial subject)

Iterative Refinement

If the user provides feedback on the tutorial:

1. Identify which Phase the feedback relates to
2. Re-execute from that Phase
3. Cascade updates to all downstream content (e.g., an environment change must propagate to subsequent steps and the Cheatsheet)
4. Maintain step numbering continuity
