AI product systems for technical builders

Build an AI product system, not just a prototype.

Turn one bounded workflow into a system with an explicit contract, governed implementation, role handoffs, guardrails, tests, evaluation evidence and a next learning loop. You can read Python or TypeScript and use Git and a terminal.

Vibe coding can accelerate a prototype. This course teaches the product system around it: what people can inspect, change, hand off, test and deliberately hold. By the end, you will be able to assemble a reusable starter folder and make the next decision from evidence — not a promise of traffic, revenue, certification, product-market fit, or production readiness.

Before you start

This is neither product-management theory nor a no-code/vibe-coding course. Learners need Git, a terminal and the ability to read Python or TypeScript. The required path stays offline and uses synthetic data; paid APIs, cloud deployment, analytics and domains are optional adapters.

Course path

Complete APD.1 → APD.15 in order. APD.1–APD.9 establish the system; APD.10–APD.15 extend it into specs, agents, guardrails, evals, an export kit and a research ledger. From APD.6 through APD.13, one fictional Event Brief decision record travels with the case: it says which version is being reviewed, what the checker did or did not test, who still owns the decision, and what to do next. Each matching lab is required practice: run it after its module, interpret the synthetic result, and keep the artifact for the next decision. The course download includes a starter folder with the companion templates.

Inspect the first decision before deciding

Read APD.1 to inspect one bounded decision on a fictional workflow. The matching offline scope-card lab is included with the complete course; it produces one complete and one held card, demonstrating a decision artifact rather than demand, safety, or launch readiness.

APD.1 is the public preview. APD.2–APD.15 and the matching labs require enrollment in the complete course.

This is a public inspection path, not a purchase flow or production authorization.

System foundation — APD.1 to APD.9

The foundation follows one fictional, low-risk workflow through nine reviewable decisions. Every exercise remains synthetic and non-production evidence; it teaches an inspectable development system, not a claim about a live product.

APD.1

Scope the decision before you build

Name the user, input, output, failure and non-goal.

APD.2

Write the product contract

Name states, evidence fields and a refusal condition.

APD.3

Map the governed repository

Connect contract, implementation, tests and change record.

APD.4

Build one reviewable vertical slice

Show a mock boundary and a visible HOLD state.

APD.5

Set the secret and safety boundary

Refuse out-of-scope input before generation.

APD.6

Keep a deterministic failure bank

Pair each invariant with a negative probe.

APD.7

Make a release decision with evidence

Distinguish synthetic PROMOTE from HOLD.

APD.8

Turn a miss into a change record

Keep the observed failure as a regression case.

APD.9

Dry-run promotion and the outside loop

State the rollback condition and next question.

Complete the system — APD.10 to APD.15

The second half extends the same fictional case into executable specifications, agent handoffs, execution guardrails, evaluation disagreement, export review and source-ledger practice. Together, the 15 modules make the full course path.

APD.10

Separate executable specs from builder guides

Keep rule, explanation, owner and change authority distinct.

APD.11

Contract role handoffs

Retain input, output, boundary, evidence and escalation.

APD.12

Check an execution boundary

Require approval, rollback and a dry-run-only plan.

APD.13

Preserve an evaluation disagreement

Version the rubric and retain a negative probe.

APD.14

Build a scrubbed export kit

Manifest what may leave; keep public metadata static.

APD.15

Maintain a research and claim ledger

Separate sourced claims from open questions.

This course teaches

A sequence for making technical AI-product decisions inspectable: scope, specification, governed implementation, agent handoffs, guardrails, tests, evaluation evidence, export and the next experiment.

What it does not establish

A synthetic exercise does not establish deployment approval, production-data safety, demand, SEO performance, revenue, or market evidence.
