The ReAct Loop Is a Prototype. This Is What Production Looks Like.

While-loop agents have no concept of phase, legal next move, or turn budget, which produces the loop spiral: forty turns in, coherence drops and tokens burn on a question the first fifteen turns already answered. A 12-phase machine with per-phase turn budgets, structural tool allowlists, and budget-pressure instructions fixes this in a production analytics agent.

Your Agent Doesn't Need a Better Vector DB. It Needs a Memory Architecture.

Vector databases solve retrieval, not the harder problem: what your agent does once it has prior context. Here's the four-type memory architecture, dual-backend storage, and mode switch that closes that gap.
