technical-tutorials

A guide for writing step-by-step technical tutorials, quickstarts, workshops, and code walkthroughs. It covers prerequisites, gradually increasing difficulty, troubleshooting, and a first successful result.

In plain words
What is it for?
Use it to create getting-started guides, hands-on coding lessons, API examples, project workshops, and explanations of existing code.
Why use it?
It helps turn technical knowledge into instructions that readers can follow and test, while reducing confusion when setup or code does not work.

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

technical-tutorials scanned grade A with 1 finding 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 2d ago.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 567 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Technical Tutorials

This skill helps you create step-by-step tutorials that actually work. Covers prerequisite handling, progressive complexity, troubleshooting sections, and creating those satisfying "it works!" moments.


Before You Start

Load your audience context first. Read .agents/developer-audience-context.md to understand:

  • Developer skill level (beginner, intermediate, senior)
  • Tech stack familiarity (what can you assume they know?)
  • Environment (macOS, Linux, Windows, cloud)
  • Why they're learning (job, side project, curiosity)

If the context file doesn't exist, run the developer-audience-context skill first.


Tutorial Types

Type Length Purpose Example
Quickstart 5-10 min First success ASAP "Make your first API call"
Tutorial 20-45 min Learn a concept deeply "Build a REST API with Node.js"
Workshop 1-3 hours Comprehensive project "Build a full-stack app"
Code walkthrough Varies Explain existing code "Understanding our SDK architecture"

Prerequisites Handling

The Prerequisites Section

Be explicit. Don't make developers guess what they need.

## Prerequisites

Before starting, make sure you have:

| Requirement | Version | Check Command |
|-------------|---------|---------------|
| Node.js | 18+ | `node --version` |
| npm | 9+ | `npm --version` |
| Git | Any | `git --version` |

You should also be comfortable with:
- Basic JavaScript (variables, functions, async/await)
- Command line basics (cd, mkdir, running commands)
- REST API concepts (HTTP methods, JSON)

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

technical-tutorials is a skill published in the GitHub repository jonathimer/devmarketing-skills (85 stars, last pushed 6mo ago), licensed MIT. It adds 64 tokens to every session and 2,975 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
