Omo Skills

Open-source AI workflow skills for teachers, tutors and small teams. Each skill is one SKILL.md file: a plain contract that says what goes in, what checks run, and what comes out. MIT licensed.

How to use a skill

1. Run it on Omo. Skills marked Run on Omo are live on omo.space. You pay per run. There is no subscription and no setup.
2. Run it yourself. Copy the skill folder into any agent that reads SKILL.md files (Hermes Agent, Claude Code, Codex and others), or implement the contract in your own stack. You supply the model keys and the checks.

A skill marked Spec only is an open contract that does not run on omo.space today. It is a good starting point, but test it before you rely on it.

Every result is a draft for a person to review. No skill here claims diagnosis, curriculum alignment or classroom approval.
