teacher-math-unit-review

teacher-math-unit-review is a skill for Claude Code, Codex from hezkvectory/hermes-edu-skills. It costs 49 tokens per session (1,421 once invoked), scanned A, original, MIT.

A lesson-review guide for maths teachers. It organises a unit around the main ideas, common reasons for mistakes, recall questions, worked examples, and new practice.

In plain words
What is it for?
Use it for unit review, exam preparation, error-focused discussions, or classes with different ability levels. It can create a knowledge structure, recall questions, mistake groups, varied exercises, and a follow-up test plan.
Why use it?
It helps teachers diagnose why students made errors instead of simply reteaching the unit or listing topics. The review ends with another check so progress can be measured.

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

teacher-math-unit-review 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 9d 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.

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.
