What is lyt-learning?

A method for breaking topics such as cross-border e-commerce, TikTok Shop, advertising, data, supply chains, business models, and AI workflows into a series of connected learning articles.

Use it to create step-by-step educational articles and advance a learner’s understanding over successive lessons.

It continues from the learner’s current understanding instead of treating every lesson as a separate starting point.

lyt-learning — Skill for Claude Code and Codex by YYYYYZhao/Lytskill

Install

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.

Any agent

npx skills add YYYYYZhao/Lytskill --skill lyt-learning

Clone the repo

git clone --depth 1 https://github.com/YYYYYZhao/Lytskill

Made for: Claude Code, Codex.

Or install lyt, the plugin that ships this one along with the rest of its 14 skills.

Per session 162 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Origin unknown No closer match found in the catalogue.

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	$0.00162	$0.01562
Opus 5.5	$0.00065	$0.00625
Sonnet 5.5	$0.00032	$0.00312
Haiku 4.5	$0.00016	$0.00156

Measured 2mo ago against content hash 0dcefa52926f, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

lyt-learning 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 2mo 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.

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

3 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.
