Synopsis

Real systems are never one style. This book composes them — and measures whether composition wins.

The final book of the series dissects common agent systems — a coding agent, a support desk, a research assistant — into the styles of Books 2–5, then builds and measures twenty hybrids on the Gauntlet benchmark.

• Routers that send easy cases to cheap styles and hard cases to strong ones
• Boundaries and adapters — what crosses, and which errors survive the crossing
• Hybrid patterns — why trees multiply errors and supervisors remove them; a supervisor over cheap peers reaches 99.5 % on research
• Deriving a design from quality attributes instead of taste
• Migrating between styles in stages, with shadow traffic and stop rules
• Failure propagation and governance of hybrid fleets
• The master’s scorecard — seven books on one page

It ends with Beat the Book: a script and a set of rules, including a hidden verification seed, that let any reader try to beat the series’ best designs — and that catch an entry tuned to luck.

Runnable code and the series’ final ten locks at tag gauntlet-b7. Book 7 of 7 in Mastering AI Agent Architectures — The Styles Series.
