You're not building one agent — over time you build a coordinated set that works like a classroom operating system. This is the menu: twenty-two agents in seven families. Tap any one for a ready-made build scaffold to take into the builder. Start with one.
Every agent has the same five parts — this is what keeps the system teachable, safe and consistent: JOB what it does · INPUT what it consumes · RULES must & never · OUTPUT what you receive · LAYER where it sits on the AI Periodic Table.
Within the rules, always: a child never types into an agent — you operate it and read every output first; no names or personal data ever go in. You can trial agents with your class as part of the project; keeping any beyond it is your school's decision.

You don't pick random tools. You compose a few agents into one teacher-conducted system for a lesson — you run them in sequence and read every output. An example:
Lesson Builder plans it

Hook Generator opens it
↓
Grow Tower Data Interpreter grounds it in real data
↓
Feedback Writer closes the loop
Together — conducted by you — that's one teaching system. Build the four ready-made agents first to see the shape: the ready-made set →
