Looking up every LL18 postcode in Denbighshire on postcodes.io, those inside the Rhyl built-up area belong to six wards: Rhyl West, Rhyl South West, Rhyl East, Rhyl South, Rhyl Tŷ Newydd and Rhyl Trellewelyn. Kinmel Bay, across the boundary in Conwy, and Rhuddlan, Prestatyn, Bodelwyddan and Dyserth each have built-up areas of their own, so this page does not count them in. Local pupils study under the Curriculum for Wales, with WJEC setting the GCSE and A level papers. We teach in English and use the Welsh school year only as a starting point that the trial lesson then adjusts. ### North Wales pages See [St Asaph](/best-coding-class-in-st-asaph), [Denbighshire](/coding-classes-in-denbighshire), [Colwyn Bay](/online-coding-and-python-classes-in-colwyn-bay) and [WJEC GCSE Computer Science help](/wjec-gcse-computer-science-help-wales). Why we want learners to reason before reaching for tools is explained in [learn to think, not just use AI tools](/learn-to-think-not-just-use-ai-tools-uk). The Rhyl project ## Four bookings, one failure, and who cleans up An agent with a multi-step job, four ways of handling failure, and a hundred thousand simulated day outs. The scenario is invented, and so are its numbers. An agent is asked to arrange a group day out in Rhyl in four steps, each handled by a separate booking system: reserve a room, book a coach, buy attraction tickets, order lunch. We gave each step a chance of failing (3%, 8%, 12% and 5%), a 4% chance that a successful booking's confirmation gets lost on the way back, and a 10% chance that a cancellation request itself fails. No real business is modelled. With those numbers, all four steps succeed about three times in four, so roughly a quarter of all attempts fail somewhere along the way. The learner runs 100,000 day outs under four policies. The first agent does nothing when a step fails: it reports the error and stops. The second cancels every earlier booking, once each. The third cancels and, if a cancellation fails, tries again, up to three times. The fourth does the same and also attaches an idempotency key to every request, a unique label that lets a booking system recognise a repeated request and return the original booking instead of making a second one. | Agent policy | Bookings left behind | Duplicate bookings | | --- | --- | --- | | Stop on failure, undo nothing | 41,272 | 13,564 | | Cancel earlier steps, one try each | 4,279 | 13,570 | | Cancel, retrying up to three times | 40 | 13,444 | | Cancel with retries and idempotency keys | 40 | 0 | Doing nothing left 41,272 stray bookings across 22,495 failed day outs: rooms reserved and coaches booked for trips that never happened. Cancelling once cut that to 4,279, and retrying the cancellations cut it to 40. Duplicates are a separate problem with a separate fix. Whenever a confirmation was lost, the agent assumed the booking had failed and asked again, and without a key each retry made a second booking, about 13,500 of them over the whole run. Idempotency keys removed every one. One more change costs nothing to try. If the riskiest step, the tickets, goes first, a failure there has nothing earlier to cancel. Re-ordering the steps from riskiest to safest cut the cancellation calls from 1.79 to 0.97 per failed day out, and the bookings left behind from 40 to 21. The success rate barely moves, since the same four steps still have to work; what changes is how much cleaning up a failure needs. ### Ages 8 to 11 Plan a party in four steps on cards, then roll a dice to see which step fails and what must be undone. ### Ages 11 to 15 Simulate the four steps in Python with random failures and count the bookings left behind. ### Ages 15 and up Add cancellations, retries and idempotency keys, then reorder the steps and measure what each change buys. ### Where this comes from The saga idea follows Garcia-Molina and Salem (1987). The day-out scenario, every failure rate, the seed (20261001) and all the counts above come from our own simulation; nothing on this page describes a real booking in Rhyl. Agents that act ## What a failed day out teaches about agents that take actions Once an agent can book, order or send, every step needs a way back. | What the simulation showed | What it means for agent builders | | --- | --- | | Stopping on failure left 41,272 stray bookings | An agent that acts must be able to undo | | One cancellation attempt still left 4,279 | The undo can fail too, so retry it | | Blind retries made duplicate bookings | Give every action an idempotency key | | Riskiest step first halved the cleanup | Order steps so failures happen early | | The scenario and rates were invented | Say clearly what is a model and what is real | AI agents are increasingly given tools that change things: sending emails, filling in forms, making bookings. Vibe coding can produce such an agent in minutes, and the happy path usually works on the first try. The saga thinking in this project is what makes the unhappy path safe. Learners here progress to agents of their own when Python no longer needs propping up, generally in the sixth form years, while Copilot Studio stays a private-lesson topic. More on our approach in [the AI agents course for UK students](/ai-agents-course-for-students-uk) and [understand the code, don't copy-paste](/understand-the-code-dont-copy-paste-uk). The ONS and postcodes.io are not connected with Modern Age Coders; their data gives the place figures. The simulation is ours. Steps ahead ## From party-planning puzzles at seven to safe action agents at seventeen The Welsh school year is our first estimate; the trial lesson sets the real starting point. Years 2 to 6 ### Plans and what-ifs Sequencing, planning and fixing mistakes, often worked out on paper.

[Vibe Coding for Teens](/courses/vibe-coding-for-teens-python-web-ai-projects-course)[Python for Teens](/courses/python-complete-masterclass-teens)Adults ### Automation that is safe Python for work and agents designed to undo their own mistakes. [Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Structures & Algorithms Course](/courses/data-structures-algorithms-masterclass-college)Undo for agents ## What is the saga pattern, and why does it matter for AI agents? The saga pattern splits a long task into steps that each have a matching compensating action, so that if a later step fails the agent runs the compensations for the steps already done, in reverse order, instead of leaving half-finished work behind. In our simulation of 100,000 four-step day outs, an agent with no undo left 41,272 bookings behind, one that retried its cancellations left 40, and idempotency keys removed about 13,500 duplicate bookings entirely. Learners who have counted those leftovers design every agent action with its undo, and they put the riskiest step first. For a Rhyl teenager, knowing how to make an agent clean up after itself is what keeps them in control of agents that act, and that grows out of building agents by hand. The longer argument is in [why learning to program still pays off in 2026](/blog/is-coding-worth-learning-2026). Lesson set-up ## Lessons for a Rhyl learner Every lesson is live on video. Learners need a computer with a keyboard, because Python is hard to run on a tablet alone. ### Learner writes it The learner types, runs and explains every program while the tutor questions. ### Placement by trial We see the learner's level in the first lesson before recommending a course. ### Free start Session one costs nothing and no card is taken. ### Small level groups Five to ten classmates at one stage, joining from across the UK. ### Two a week in term About eight lessons a month, with Denbighshire holidays left clear on request. ### Same UK time The lesson time holds steady through the clock changes. Why lessons are online Five to ten learners at exactly one level are much easier to group from the whole UK than from one seaside town, and video saves everyone the journey. Fees ## Fees for Rhyl families Rhyl learners pay the same as all learners outside India. First class**USD 0** First lesson: free, a full session, finishing with a course recommendation. Group tuition**USD 100** Group class, usually eight lessons a month. Private tuition**USD 150** One-to-one lessons, usually eight a month. We charge in US dollars and show no sterling price. You pay nothing for the trial; invoices start once the course and the weekly time are settled. Breaks for holidays, lessons you miss and swaps from group to private are all set out on the pricing page.

Submitted details are used for placement and follow-up. FAQ ## Rhyl questions The booking agent project, sagas, vibe coding and how lessons work. ### How many people live in Rhyl? The ONS counted 26,990 usual residents in the Rhyl built-up area at the 2021 census. Denbighshire had 95,817. ### Are vibe coding and AI agents classes available in Rhyl? Yes. Live online classes are open to ages 6 to 67 in Rhyl and across Denbighshire. ### What is a compensating action? An action that undoes the effect of an earlier completed step, such as cancelling a booking, used when a later step in the same task fails. ### What is an idempotency key? A unique label sent with a request so that, if the same request arrives twice, the system carries it out only once and returns the original result. ### What did the Rhyl simulation show? Over 100,000 invented day outs, an agent with no undo left 41,272 bookings behind; retried cancellations brought that down to 40, and idempotency keys stopped all duplicate bookings. ### What is vibe coding? Asking an AI to write code from a description, then running, reading and correcting it. We teach it in typed Python so learners can judge what the AI produced. ### When do learners build their own AI agents? Once their Python runs without support, for most from Year 12. Copilot Studio agents are taught one-to-one only. ### Does this help with WJEC GCSE computer science? WJEC computer science at GCSE and A level asks for programming, algorithms and testing, and our lessons build all three thoroughly. Grades are not promised. ### What do lessons cost? Trial: free. From then on, USD 100 a month in a group or USD 150 a month privately. ### Can lessons stop for school holidays? Yes. Let us have the Denbighshire school calendar and lessons skip the breaks.
