Own the architecture before you prompt

A model will write whatever you point it at. Pointing it well is architecture: boundaries, data flow, and contracts decided before any code exists. This lesson is the mental model a senior holds that a prompt-paster does not.

Write the spec the model can hit

A prompt is a specification. The difference between a junior and a senior prompt is the constraints a senior names that a junior leaves to chance. This lesson turns your architecture sketch into a prompt that produces reviewable code.

Cut the work into agent-sized tasks

Ask for a whole feature in one prompt and you get a wall of code you cannot review. The senior move is decomposition: slices small enough to verify in one pass, sequenced so each builds on a reviewed foundation.

Review what comes back like a senior

Models produce confident, plausible, well-formatted code — which is exactly what makes their mistakes dangerous. This lesson is the review rubric: the specific failure classes to hunt for, because "it looks right" is not review.

Orchestrate agents without the codebase rotting

Putting it together: context, guardrails, and a verification loop that lets you run coding agents across a real codebase without it drifting into an incoherent pile. This is the senior loop at full speed.
