Vibe coding and AI agents classes in Fremantle

What can a Fremantle learner build with an AI agent?

An agent that answers questions from public data and is honest about what that data contains. In our Fremantle project the agent ranks counted places using two Main Roads tools, one for vehicles and one for bicycles. The tools name the same idea differently. Learners write a small adapter so the agent sees one clear schema and never turns a missing count into a zero.

The City of Fremantle is small, at about 19 square kilometres, and busy. Main Roads lists 46 vehicle count sites on 27 roads here, plus 7 permanent bicycle counters on paths by the beaches, the river and the railway. Those two lists are a ready-made test of how an AI agent copes when its tools disagree about names.

Fremantle by the numbers

Older terraces, short commutes and a port city

Figures for the City of Fremantle council area (ABS LGA53430), from 2021 Census QuickStats read on 12 October 2026, with the latest ABS estimate.

Professionals among workers37.5% (6,213)22.0%

Children

Residents aged 5 to 9 numbered 1,449, or 4.5%, below the 6.5% share for Western Australia.

Degrees

Of residents aged 15 and over, 39.2% held a bachelor degree or higher, against 23.8% statewide.

Growth

The ABS estimate of 37,542 residents for 2025 sits well above the 2021 Census count. They are different measures, so we show both and leave them unsubtracted.

The Census was taken during the pandemic, so the travel-to-work shares describe that week. The ABS rounds figures and lightly perturbs small counts, so parts of its tables may not add up to its totals; we quote each number as published.

Signature project

Two tools, one question, one adapter

The task given to the agent is short: rank the counted places in Fremantle by how much traffic they carry. It has two tools. One returns Traffic Digest rows for vehicles; the other returns Bike Count Sites. Only 10 field names appear in both, and none of them is a volume.

Adapter, then rank by mode46 vehicle sites and 5 bike counters ranked; 2 marked as no count yet

The quiet failure

The second version is worse than the crash. It looks finished, yet it reports the path counter at Stirling Bridge, averaging 703 riders a day, as carrying nothing.

Missing is not zero

Two underpass counters were commissioned on 21 July 2026 and have no counts yet. The adapter maps their volume to None and the agent says so in words.

Separate rankings

Mixing modes puts the busiest bike counter 45th of 51, behind 44 vehicle sites. The adapter adds a mode field, and the agent ranks vehicles and bikes apart.

What the adapter reveals

Once both tools speak one schema, a real local pattern appears. Four of the five counted bike paths are busier at the weekend than on weekdays; the path at Stirling Bridge rises from 619 to 911 riders. Vehicle sites go the other way, with a median weekend to weekday ratio of 0.908.

Volumes come from the Main Roads Traffic Digest and Bike Count Sites layers, downloaded on 12 October 2026, for sites Main Roads assigns to the City of Fremantle. Count years differ between sites, from 2021/22 to 2026/27. The adapter, the rankings and the ratios are our own scripts and calculations.

Building the adapter

One function between the agent and its tools

An adapter is a translation layer. It takes a row from either tool and returns a dictionary with the same keys every time.

Lesson steps
StepLearner task
1Print the keys of one row from each tool and list the shared names.
2Run the naive ranking and read the KeyError carefully.
3Write adapt(row) returning site, road, place, mode, per_day, weekday, weekend and year.
4Give the agent only adapted rows, and test it on a counter with no data.

Step 4 is where most first attempts slip. A default of zero feels harmless while writing the adapter, but it turns a new counter into a dead path. Learners write a test that feeds in a bike row with blank volumes and asserts that the agent's answer contains the words no count yet. When the agent later meets a third tool, such as pedestrian counts, the same adapter pattern absorbs it in a few lines.

Younger learners

Translate two picture cards that say the same thing in different words, then make one shared card.

Teenagers

Write the adapter in Python, then let an AI assistant extend it and check every field it maps.

Adults

Put adapters between an agent and two internal systems that disagree about names and units.

Around Fremantle

Bridges, beaches and the 2027 school year

Local details from the two Main Roads layers and the WA Department of Education.

Busiest road site

Stirling Highway north of Stirling Bridge averages 36,707 vehicles a day across the week, from a 2023/24 count.

Coast path

The South Beach counter north of Douro Road averages 359 riders a day, with 174 heading to Fremantle and 185 to Coogee.

Term 3, 2027

WA public schools run Term 3 from Monday 19 July to Friday 24 September 2027, a good moment to begin or switch a course.

Area used

The council area is the ABS outline of about 19.3 square kilometres. Count sites are those Main Roads attaches to the City of Fremantle. Our point-in-polygon test places 11 government schools inside the outline.

Why teach adapters when agents can write them?

Because an agent that guesses field names can be confidently wrong.

Ask a coding agent to merge the two Fremantle tools and it may well produce a working adapter. It may also choose the primary-direction column instead of the combined one, or fill gaps with zero, and the output will still look tidy.

A learner who has mapped the fields by hand knows which column means both directions and why a blank must stay blank. That knowledge turns a plausible draft into a checked one.

Fremantle learners let agents draft the glue code and then read every line of it. The longer argument is in why checking code still beats trusting it in 2026.

FAQ

Fremantle vibe coding and agents questions

Questions from Fremantle families and adult learners.

How many people live in the City of Fremantle?

The 2021 Census counted 31,930 residents, with a median age of 42. The ABS estimate for 2025 is 37,542.

What is an adapter in programming?

A small piece of code that converts data from one shape into another, so the rest of a program, or an agent, only has to understand one format.

Why not just use a default of zero?

Because a missing count and a count of zero mean different things. In Fremantle, two new path counters would be reported as unused.

What is vibe coding?

Building software by describing what you want to an AI assistant and steering its drafts. Our classes add the reading and testing that keep the result correct.

Are agents safe for children to use?

Younger learners work with guided, age-appropriate tools in class. Open agent tools come later, under supervision and within each tool's age rules.

How many bike counters are in Fremantle?

Main Roads lists 7 permanent bicycle counters in the City of Fremantle, five of them with counts in the data downloaded on 12 October 2026.

Do you have a centre in Fremantle?

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

What do Fremantle classes cost?

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 will my child learn with?

Fifteen to twenty learners matched by level and pace, not by age or suburb. One-to-one lessons are there when no group time fits.

Can adults learn about agents?

Yes. Adults join adult groups or private lessons and often build agents around their own tools at work.
