A video-making workflow that turns a reading unit from the Echo Reading project into a narrated teaching video. It currently supports only the Chinese classic Tao Te Ching.

It helps write narration, create text-to-speech timing and storyboards, render 16:9 videos, and re-render or inspect videos for a Tao Te Ching chapter or unit.

It converts preparation notes into a structured video, so the material can be studied or explained in video form.

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	$0.00148	$0.02628
Opus 5	$0.00074	$0.01314
Sonnet 5	$0.00030	$0.00526
Haiku 4.5	$0.00015	$0.00263

Security

Grade A, and why

unit-video 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 3d ago.

The scan reads SKILL.md. This mod also ships 30 executable files (assets/道德经/水墨卷轴/配置.js, dist/cli/align-durs.js, dist/cli/draft-storyboard.js, …), 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

56 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.
