# Agents in Depth

These pages hold the full detail behind [How Durable Agents Work](https://docs.superdurable.io/agent-frameworks/how-it-works.md) and [Framework Support](https://docs.superdurable.io/agent-frameworks/framework-support.md).

- [Sessions](https://docs.superdurable.io/agent-frameworks/sessions.md): what a session keeps, what a turn costs, and what a session remembers.
- [Tool Calls](https://docs.superdurable.io/agent-frameworks/tool-calls.md): tool policies, each call outcome, and how to reconcile an unknown one.
- [Approvals](https://docs.superdurable.io/agent-frameworks/approvals.md): answer an approval from your application or in Dex Web.
- [Connectors as Tools](https://docs.superdurable.io/agent-frameworks/connectors-as-tools.md): offer official Connector operations as tools, for each framework.
- [Built-in Agent Loop](https://docs.superdurable.io/agent-frameworks/built-in-agent-loop.md): the harness with durable context, Steer, questions, plans, and live events.
- [How Each Framework Runs on Dex](https://docs.superdurable.io/agent-frameworks/framework-details.md): how each adapter runs a turn as Steps, and its full limits.

The versioned [Agents reference](https://docs.superdurable.io/reference/agents.md) has configuration, limits, and version details.
