Professional Agentic Product Engineering

Chapter

The six tiers at a glance

Stage Tier You stop doing by hand What you do instead Pain that pushes you up
Direct T1 Prompt Writing the code by hand State the outcome You re-explain the same things; big asks go sideways
Direct T2 Plan Explaining the project; steering each step Decide the plan and the slice You can't trust the output without reading every line
Trust T3 Verify Reading every line Define "done" You give the same correction again; "remember to run the tests"
Trust T4 Enforce Reminding and approving Write the rules One agent is too slow, or a big build floods its context
Scale T5 Orchestrate Running agents one by one Split and coordinate the work Runs die when you leave; you start every run yourself
Scale T6 Supervise Starting and watching runs Certify the evidence; improve the system — (top)

Three stages, two tiers each — and every tier name is a verb for what you do:

Stage Tiers What it gets you
Direct T1 Prompt · T2 Plan Get the right work
Trust T3 Verify · T4 Enforce Stop checking it yourself
Scale T5 Orchestrate · T6 Supervise Stop running it yourself
