# Reasoning

> How the Reasoning tool keeps the assistant’s chain-of-thought transparent and your requests on track

The **Reasoning** tool is the first—and most frequent—step the assistant takes after you send a message.\
Think of it as the AI’s “inner monologue,” surfaced in plain language so you always know *why* it is about to do something.

## 🚀 Why it matters

* **Clarity & Trust** – You see the numbered thought process before any agent or app acts on your data.
* **Zero-guess Workflow** – The assistant pauses to ask clarifying questions *before* it locks in a plan.
* **Seamless Orchestration** – Between every agent hand-off, Reasoning pops up again with a quick 1-2-sentence checkpoint, so the whole swarm stays in sync.

## 🔄 When it runs

1. **Immediately after every user message** (mandatory first tool call).
2. **At least twice** before the assistant generates an *Agent Plan*.
3. **Between every agent hand-off** during multi-agent workflows.
4. **Even on tiny replies**—no exceptions.
