Introducing Agentic Autonomy

As LLMs transition from assistants to proactive decision makers, software engineering faces a paradigm shift.

1. The State Preservation Engine

Unlike chat sessions, autonomous agents require highly granular memory cells.

> [!PULL] High-velocity systems cannot route every query through the most expensive model. Triage is mandatory.

2. Deterministic Control Loops

To stop agents from spiraling, we must wrap them in rule-based bounds. Every agent needs a "Circuit Breaker" to prevent hallucination debt.

Conclusion? Build with guards. Validate structures.
