Using screenshots as part of an iterative interface-building workflow.
Backend Architecture
Thinking beyond the visible interface when shaping a working application.
Prompting Constraints
Giving AI clear boundaries and useful direction while keeping human judgment in the loop.
Agent Teams
Exploring multi-agent orchestration as part of an AI-assisted software workflow.
Verification Gates
Checking the work rather than assuming generated software is ready to ship.
Vibe Coding to Agentic Engineering
IDEA
Start with the problem and the outcome you want to build.
BUILD
Use AI assistance to turn the idea into working software.
GOVERN
Apply constraints, review, and verification to guide the work.
SHIP

Inside the Book
Four practical frameworks for guiding AI-assisted software work from prompts to launch:
- Eight prompting principles, including inspect before patch, preserve behavior, and verify narrowly.
- Specialist-agent roles that divide planning, coding, design, research, documentation, and coordination.
- Verification gates, including browser-level Playwright checks before shipping.
- A seven-point production-readiness audit covering the Dev/Prod split, health checks, and provider fallbacks.
