# Agent Workflows: Internal Architecture

> Internal notes on how agent workflows are composed from triggers, capability steps, handoffs, and approvals, with receipts at every step for continuity.

Internal architecture note for agent workflows. Product-level view is at [Workflows](/agents/workflows).

## Composition

* **Trigger** — an event, a schedule, or a human intent.
* **Steps** — capability invocations, in sequence or in parallel.
* **Handoffs** — between agents or to a human.
* **Approvals** — where policy requires human review.
* **Receipts** — captured on every step for audit and continuity.
