What is teaching-viz?

A tool that turns Markdown teaching material into interactive learning cases and supporting files, including code, articles, diagrams, mind maps, and HTML demonstrations. Markdown is a plain-text format for writing structured documents.

It is for creating interactive teaching cases for Astro, React, and WebContainer projects, with executable examples and visual explanations.

It converts one source document into several formats that students can read, run, and explore progressively.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.01795
Opus 5.5	$0.00025	$0.00718
Sonnet 5.5	$0.00012	$0.00359
Haiku 4.5	$0.00006	$0.00179

Security

Grade A, and why

teaching-viz scanned grade A with 0 findings 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.

The scan reads SKILL.md. This mod also ships 3 executable files (assets/site/astro.config.mjs, assets/site/cases/01-atomic-change/index.mjs, assets/site/cases/lib/engine.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What ships with it

60 files 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.
