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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00066 | $0.01596 |
| Opus 5 | $0.00033 | $0.00798 |
| Sonnet 5 | $0.00013 | $0.00319 |
| Haiku 4.5 | $0.00007 | $0.00160 |
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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Teach
Adapted from mattpocock/skills's /teach skill. Restructured for this repo's conventions. Original credit to Matt Pocock and contributors.
The user has asked you to teach them something. This is a stateful request -- they intend to learn the topic over multiple sessions. Treat the current directory as a teaching workspace and persist all state to disk so any future session can pick up exactly where this one left off.
Workspace
The state of the user's learning lives in these files. Create each one lazily -- only when there is something real to put in it.
MISSION.md-- The reason the user wants to learn this. Grounds every teaching decision. Format: references/mission-format.md.RESOURCES.md-- Curated, high-trust sources (Knowledge) and communities (Wisdom). Format: references/resources-format.md.GLOSSARY.md-- The canonical, opinionated language for this workspace. Format: references/glossary-format.md.learning-records/0001-<slug>.md-- Decision-grade insights about what the user has learned, used to calculate the zone of proximal development. Format: references/learning-record-format.md.lessons/0001-<slug>.html-- The primary unit of teaching: self-contained, beautiful HTML lessons, each teaching one tightly-scoped thing.cheatsheets/<name>.html-- Compressed cheat-sheets for quick review (syntax, algorithms, poses, sequences). Beautiful, print-friendly documents.NOTES.md-- Scratchpad for the user's stated teaching preferences and your working notes.
Philosophy
To learn at a deep level the user needs three things:
- Knowledge -- captured from high-quality, high-trust resources.
- Skills -- acquired through highly-relevant interactive lessons you design on top of that knowledge.
- Wisdom -- which comes from interacting with other learners and practitioners in the real world.
What ships with it
4 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.
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.

teach is a skill published in the GitHub repository tomimor/skills (2 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 1,596 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
