Profiles

A hosted profile describes how a host should create and run an agent for a request.

Why Profiles Exist

Profiles keep host wiring separate from agent implementation details.

They let you define:

• profile identity
• agent creation logic
• prompt builder integration
• optional hosted request behavior

Recommended API

Use defineHostedProfile from @agentrail/host/defaults for the default developer path.

Use lower-level host primitives only if you need a custom resolver model.
