teach

teach is a skill for Claude Code, Codex from alyraffauf/hoenn. It costs 60 tokens per session (1,424 once invoked), scanned A, original, GPL-3.0.

A teaching aid for explaining a body of software work in plain language. It combines explanations of how a system works with why its parts and changes matter.

In plain words
What is it for?
Use it when learning a code change, feature, or subsystem, especially when you need an explanation of both its operation and its reasons.
Why use it?
It helps someone understand unfamiliar code or a subsystem instead of only seeing a list of implementation details. The explanation is intended to make the relationships and purpose of the work clear.

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

teach 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 today.

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

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.
