A tiny campus agent

In one sentence

An agent is a loop with tools: search notes, draft, check. Your project is a campus FAQ bot that refuses guesses.

AI is not a person. It is a next-word engine with a very good memory of patterns.

Read the idea, watch the picture, then try it with your hands.

Watch the idea

The concept

Think

Plan the next step

Tool

Search, write, call

Check

Did it actually finish?

Human gate

Before it leaves the building

An agent is a loop, not a soul

Think: plan the next step. Act: call a tool (search, calendar, code). Check: did the tool result actually answer the job? Repeat until a stop rule. That is a clerk with a checklist.

Tools without gates are accidents

A campus agent that can send mail, book rooms, or edit grades needs a human gate before anything leaves the building. Confidence is not permission. Stop rules belong in the prompt and in the code.

Start tiny

One job: office hours FAQ over the course handbook, with retrieval and a refuse path. Not an unsupervised registrar. Tiny, gated, measurable agents are how you learn the pattern before you scale it.

Worked example

The handbook bot

Student asks when the lab is due. Agent retrieves the syllabus span, answers with a citation, and stops. If the syllabus is silent, it says it does not know — it does not invent a midnight deadline.
