Vibe coding and AI agents classes in Chatswood

Where do Chatswood learners find the best vibe coding and AI agents classes?

In live online lessons that teach teenagers and adults to build agents and to test them properly, not only to prompt them. The 2021 Census counted 25,553 people in Chatswood, 67.6% of occupied homes flats or apartments and 52.7% of residents aged 15 and over holding a bachelor degree or higher. Lessons are private or in small level-matched groups, and the first is free.

Here is a test that every AI agent builder should run. We asked three simple agents the same question: which month had the most entries at Chatswood Station? All three said August 2026, with 949,108 entries, and all three were right. One read every month. One read only the last three. One read every month but compared the numbers as text. Grading only the final answer gives all three full marks. Grading the path each agent took exposes two of them, and running them across every station proves why that matters.

Vertical living

Separate houses were only 27.9% of occupied homes, where across NSW they were 65.6%.

Walkers

Nearly three times the state share walked to work on Census day, 856 people in all.

Census day context

The Census was taken in August 2021 during lockdowns, and 49.9% of employed residents worked at home that day.

Privacy adjustments mean the bureau's cells may not sum exactly to its totals. We quote its published figures and never make a total by adding parts.

Signature project

Three agents, one right answer, two bad paths

Each agent has one tool: fetch the entry count for a given station and month from Transport for NSW's monthly data. The question is the busiest month at Chatswood Station from October 2024 to August 2026.

The three agents at Chatswood (our calculation)
AgentWhat it doesTool callsAnswer at Chatswood
AReads all 23 months and compares numbers23August 2026, correct
BReads only the last 3 months3August 2026, correct
CReads all 23 months but compares them as text23August 2026, correct

AgentCorrect answersTotal tool calls
A338 of 3387,774
B29 of 3381,014
C259 of 3387,774

Agent B got lucky

Chatswood's record month happens to be the last one, so a three-month look finds it. At most stations the record is earlier; March 2026 was the busiest month at 177 of them.

Agent C got lucky too

Text comparison puts 949,108 above 686,889 because both have six digits. It fails whenever counts have different lengths, which is why it was right at exactly the 259 stations whose counts all had the same number of digits.

Agent A earned it

Reading every month and comparing numbers is the only path that would be right anywhere, and the trajectory shows it.

What a trajectory check looks like

Instead of asking only whether the answer matched, the grader reads the agent's log: did it fetch every month in the range, did it parse each count as a number, did it compare the right values? Agent B fails the first check and agent C fails the second, even at Chatswood where their answers were correct.

The agents, their tool logs and all counts of correct answers are our own, written for teaching from the published monthly figures. Entry counts measure gate entries and the page draws no conclusion about why any month was busier.

Grading agents properly

Answer checks, path checks, and why you need both

Teams that ship agents test them in layers. The Chatswood project gives learners a small version of each layer.

Layers of agent evaluation
CheckQuestion it asksCatches
Final answerDid the output match the known answer?Plainly wrong answers
CoverageDid the agent look at everything it needed?Agent B's three-month shortcut
TypesWere values handled as the right kind of data?Agent C's text comparison
Many casesDoes the behaviour hold across varied inputs?Lucky passes on one example

The last row is the cheapest lesson of all. One station, Chatswood, made every agent look good. Three hundred and thirty eight stations separated them completely. A test set with many varied cases is the first thing to build, before any clever prompt.

Teenagers

Write the three agents in Python, log every tool call, and write a grader that reads the log.

University students

Design evaluation sets that mix easy, tricky and adversarial cases, and measure agents with both answer and path scores.

Adults at work

Apply the same checks to workplace agents before they touch real systems or real customers.

Transport for NSW, Willoughby City Council, the NSW Department of Education and the statistics bureau provide the open data used here and have no connection with Modern Age Coders.

Around Chatswood

A school from 1883 and a very busy station

A few more facts from the department's files and the station data.

Chatswood Public School

The NSW Department of Education dates the school's first teacher to July 1883.

Chatswood High School

The department's file gives January 1959 for the high school's first teacher.

The quietest month

In the station data the lowest month was January 2025, with 686,889 entries; January 2026 was the second lowest at 724,159.

A shared station

Transport for NSW labels Chatswood Station as Metro Shared in its monthly file, one of five stations with that label among 383 in the data.

Agents can already answer questions. Why should a Chatswood learner build the grader?

Because an agent that is right for the wrong reason will eventually be wrong, and only someone who reads the path will see it coming.

Agent C in our project is right at Chatswood and wrong at 79 other stations. Nothing in its answer warns you; the flaw is visible only in how it compared the numbers. Real agents fail in the same quiet way when they skip data or mishandle types.

A learner who has built all three agents and the grader reads any AI system differently. They ask what the agent looked at, how it handled each value, and whether it was tested on many cases or just one convenient example.

In 2026 the Chatswood learners who can grade agents will be the ones trusted to build them, and that skill starts with writing and testing code yourself. The longer argument is in why teenagers should still learn to code in 2026.

A real trial

The free first lesson is a proper class, followed by a recommendation and nothing to pay.

Level-matched groups

Fifteen to twenty learners at the same level, or one to one when that suits better.

Regular rhythm

Two fixed lessons a week, about eight a month, with breaks planned in advance.

Teachers in India

A 6:30pm Chatswood lesson in summer starts at 1pm India time, and at 2pm once Sydney ends daylight saving.

FAQ

Chatswood vibe coding and AI agents questions

What Chatswood families and adult learners usually ask first.

How many people live in Chatswood?

The 2021 Census QuickStats for the Chatswood suburb record 25,553 residents and a median age of 37.

What is trajectory evaluation for AI agents?

Trajectory evaluation grades the steps an AI agent took, such as which tools it called and what it did with the results, instead of only checking whether its final answer was correct. It catches agents that reach a right answer by a wrong or lucky route.

What is the Chatswood agent project?

Learners build three agents that find the busiest month at Chatswood Station from Transport for NSW data. All three answer August 2026 correctly, but across 338 stations one is right every time, one only 29 times and one 259 times. Learners then write a grader that reads each agent's steps.

Why does comparing numbers as text go wrong?

Text comparison goes character by character, so 99,000 sorts above 100,000 because 9 comes after 1. When all the numbers have the same length it happens to work, which is how the text-comparing agent stayed right at Chatswood.

Do I need to know Python first?

Not for the first lessons. Beginners start with simpler projects and reach agents once they can write and read short programs.

Are Copilot Studio agents taught in groups?

No. Copilot Studio is taught one to one only, because every workplace has its own data and permissions. Teenagers build agents in Python.

Can younger children join?

Yes, from age six, starting with Scratch and simple vibe coding. The agent project is for older students.

Do you have an office in Chatswood?

No. All lessons are live online and we have no premises in Australia. The phone number on our site is Indian.

What do AI agents classes cost in Chatswood?

The first lesson is free. Then a group place is USD 100 a month for two live lessons a week, about eight a month, with fifteen to twenty learners, or USD 150 a month one to one.

How many learners are in each group?

Fifteen to twenty, grouped by level and pace. If no group fits, one-to-one lessons are offered.
