Module 2: The Rehearsal

The objective of the Rehearsal is to front-load all hard, collaborative thinking before a single line of code is written.

The Goal: Correctness and Completeness

A successful Rehearsal ensures the plan is:

The ROI: Every minute spent here saves ten minutes of patching “AI slop” later.

Topic	Key Takeaway
Active Context Management	You are responsible for the AI’s “working memory”
Constraint Navigation	AI fails when it hits unwritten rules; the Rehearsal makes these rules explicit
Quantitative Validation	The confidence score is a “gut check” for readiness, not a guarantee of perfection
The “AI-Friendly” Mindset	Treat the AI like a smart intern: guide it, don’t just prompt it

Building the AI’s world by explicitly directing context creation

Design and constraint exploration before implementation

The pre-flight check to ensure total synchronization

Time Investment: ~75% of the total workflow Why: Getting alignment upfront prevents expensive rework later
