# Agentic Architecture

> A design pattern in which the model chooses actions from a scoped set of tools, within a step limit and under review.

Record: `architecture:agentic-architecture`
Kind: pattern
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Model Drift Monitoring](https://banes-lab.com/records/architecture/model-drift-monitoring.md) and before [Observability](https://banes-lab.com/records/architecture/observability.md).

## Repair

- Refactored by: Bound the Agent with Tools, Limits, and Review
- Detected by: agent actions without tool scoping or step limits
- Violated by: an unbounded model loop acting with no guardrails
- Measured by: unguarded agent action rate
- Enforced by: model safety review
