Vibe coding and AI agent classes in Tea Tree Gully

Why do AI agents in Tea Tree Gully projects pick the wrong tool?

Usually because the tool descriptions do not say clearly what each tool does, so the agent guesses from names. Our live online classes teach learners to write tool descriptions an agent cannot misread. The City of Tea Tree Gully had 101,174 residents in 2021.

Asked how many bus stops serve Tea Tree Gully, our scripted agent answered: none. Not one stop name in South Australia's timetable contains the words "Tea Tree Gully". The agent had searched names because both of its tools were described the same way, as "find stops for a place".

Courses for building agents that choose well

This project needs Python functions, docstrings and an understanding of how agents read tools. These courses build all three; a free trial lesson finds the fit.

Tea Tree Gully in the Census

Separate houses and bus commuters in the north-east

Council-wide figures from the 2021 Census for the City of Tea Tree Gully (ABS code LGA47700), set beside South Australia.

School ages

Residents aged 5 to 9 numbered 6,030, aged 10 to 14 6,173, and aged 15 to 19 5,846.

Older residents

2,482 residents were aged 85 or over.

Size

The council area spans about 95 square kilometres in the north-east of Adelaide.

Figures are exactly as the ABS released them; its privacy noise on small cells is one reason we never add them up.

Signature project

Same description, wrong tool

The agent had two Python functions available as tools. stops_named(text) searches stop names. stops_in_council(name) returns stop records whose location falls inside a council boundary. In version one, both docstrings read "Find stops for a place."

What each tool returned for Tea Tree Gully (our run on timetable version 1708)
Tool callResult
stops_named("Tea Tree Gully")0 stop records
stops_named("Tea Tree")8 records, all at one interchange
stops_in_council("Tea Tree Gully")607 stop records

stops_namedFind stops for a place.Search stop NAMES for text. Suburb and council names rarely appear in stop names.
stops_in_councilFind stops for a place.Return every stop record located inside a council boundary. Use for questions about an area.

What the agent saw

With identical descriptions, the agent had nothing to go on but the function names, and "named" sounded like the right match for a place name.

What changed

With version two, our scripted agent chose stops_in_council and reported 607 stop records. Nothing else about the agent or the data changed.

Why zero was believable

An empty result looks like an answer. The agent reported "no stops found" with no error, which is exactly why it is dangerous.

Descriptions are instructions

For an agent, a tool's description is the main evidence for when to use it. Write what the tool does, what it does not do, and when to prefer another tool. Test with a question that only one tool can answer correctly, as Tea Tree Gully does here.

Adelaide Metro publishes the timetable openly; working out which stops fall within the council, and all the tallies, was done in our own code. The agent is a small script of ours built to isolate the effect of wording, so no commercial model's output appears here.

Agents and tools

Writing tool descriptions an agent can use

A few lines of plain English decide most tool choices.

Primary learners

Label two boxes so clearly that a friend always picks the right one without asking.

Secondary learners

Give an AI tool two functions with vague docstrings, ask it a question, then rewrite the docstrings and ask again.

Adults

Review the descriptions of tools your agents use at work, especially pairs that sound alike.

Good descriptions help people too. The same docstring that steers an agent tells the next programmer what the function is for.

Vibe coding and agents

If the agent picks the tool, who writes the label?

The person building the agent. An agent can only be as precise as the descriptions it reads.

Vibe coding often means asking an agent to "add a tool for that". It will, and it may describe the new tool in the vaguest possible words. Later, when two tools sound alike, the agent chooses by guesswork and reports the result with confidence.

Learners who have watched "no stops" become 607 with two rewritten sentences treat tool descriptions as part of the program. That is how they build agents that keep working as more tools are added.

In Tea Tree Gully, the learner who writes clear tool descriptions gets the 607, not the zero. The longer argument is in why teenagers should still learn to code in 2026.

FAQ

Tea Tree Gully vibe coding and agent questions

Questions from across the City of Tea Tree Gully.

What is the population of the City of Tea Tree Gully?

The 2021 Census QuickStats count 101,174 residents in the City of Tea Tree Gully local government area, with 41,022 private dwellings and a median age of 41.

What is a tool description for an AI agent?

A short text, often a function's docstring, telling the agent what a tool does and when to use it. Agents rely on it to choose between tools.

Why did the agent report no stops?

It searched stop names for "Tea Tree Gully" because both tools were described identically. No stop name contains those words, so the search returned zero.

How many stop records are in the City of Tea Tree Gully?

By our boundary check of the Adelaide Metro timetable, 607 stop records lie inside the council, with 27,084 scheduled visits on Wednesday 21 October 2026.

What does vibe coding mean in practice?

You explain the program you want to an AI assistant, it drafts the code, and you test, question and refine that draft until it works properly.

Is Claude part of the teen courses?

No. We keep Claude for learners who are 18 or older, and teenagers work with other AI tools.

Is there a classroom in Tea Tree Gully?

No. Lessons are live online only, we have no Australian office, and our listed phone number is Indian.

What do lessons cost for Tea Tree Gully learners?

The first lesson is free. Group classes cost USD 100 a month for two live lessons a week, about eight a month, in groups of fifteen to twenty, and one-to-one classes cost USD 150 a month. You agree the course and time before paying.

Who is in each group?

Fifteen to twenty learners at a similar level and pace, not sorted by age or suburb. One-to-one lessons suit anyone no group time fits.

Can a group class here cover Copilot Studio?

No. We teach Copilot Studio only in private lessons; groups write agents in Python.
