# Product Engineering Agents: Twin and Domain Specialists

> Twin and the specialized agents that operate in the Product Engineering domain, from triage to schema reasoning.

The Product Engineering domain is served by Twin and a set of core and domain-specific agents. Each agent has a scoped responsibility and collaborates through the Spine agent network.

### Twin

Twin is your personal AI operator in the Product Engineering workbench. It assembles context for issues, PRs, and incidents; drafts proposals; and routes work to specialized agents when needed.

### Core Agents

* **Discovery Agent**: Identifies related work across tickets, PRs, and incidents that may not be explicitly linked. Surfaces hidden dependencies.
* **Triage Agent**: Handles incident intake, severity scoring, on-call routing, and initial impact assessment.
* **Schema Agent**: Reasons about data model changes, maps fields across systems, and flags migration risks.

### Domain Agents

* **Release Agent**: Monitors release pipelines, flags blockers, and drafts rollout summaries from deployment and monitoring data.
* **Code Review Agent**: Surfaces stale reviews, links issues to PRs, and suggests reviewers based on expertise and availability.
* **Roadmap Agent**: Tracks epic health, forecasts completion risk, and alerts when scope or deadlines shift.

Agents communicate through the Spine Fabric, so each agent operates on the same unified context.
