The Plan-Execute-Review Pattern
The three-phase workflow for reliable agent-driven development: plan mode, execution, and human review.
The most common mistake developers make with AI agents is typing "build me a login system" and letting the agent loose. Sometimes it works beautifully. Sometimes it creates a login system that stores passwords in plain text, doesn't handle edge cases, and uses deprecated libraries.
The difference between those outcomes isn't the agent — it's the process. The plan-execute-review pattern adds structure that makes agent output consistently reliable. It's the same reason construction projects have blueprints and inspections — the building phase is only one part of the process.
The Three Phases
Phase 1: Plan
Before the agent writes a single line of code, it creates a plan. The plan describes what will be built, how it will be built, and what assumptions are being made.
