# Agentic Workflows and Tool Use

## Prerequisite

**Agentic Workflows and Tool Use**

## Why It's Required

Essential for understanding the context of the benchmarks and why model persistence is the most important feature of [[entity-claude-opus-4-7-d12|4.7]].

## What You Should Already Know

The analysis heavily relies on the concept of 'agentic workflows' — where:

- An LLM is given a **high-level goal**.
- The LLM has access to **tools** (terminal execution, web search, file I/O, code execution).
- The LLM **loops autonomously** to complete the task.

## Why It Matters for This Source

Understanding this paradigm is essential to grasp why:

- [[concept-agentic-persistence|Persistence]] is a critical metric (the agent must keep going through long horizons).
- [[concept-trust-failure-hallucination|Audit trails]] are a critical metric (downstream systems depend on knowing what actually happened).
- The Hex eval method ([[framework-hex-eval]]) is structured the way it is.
- [[action-build-deterministic-evals|Deterministic verification]] is the only viable safeguard.

Without this paradigm, the entire conversation about 'co-workers vs. chatbots' doesn't make sense.
