Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00064 | $0.02975 |
| Opus 5 | $0.00032 | $0.01488 |
| Sonnet 5 | $0.00013 | $0.00595 |
| Haiku 4.5 | $0.00006 | $0.00298 |
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.

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)
**New to any of these?** Check out [link to prerequisite tutorial].
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.
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.
