Agent Roles and Collaboration

Definition

Agent roles are scoped responsibilities assigned to specialized workers in a swarm. Collaboration is the protocol for how those workers hand off context, validate outputs, and escalate risk.

Why it matters

Clear roles reduce duplicated effort, lower coordination overhead, and make quality gates auditable. Role clarity often has more impact than model size when workflows become multi-step and high-risk.

When to use

Use role-based collaboration when tasks require parallel execution, independent verification, or explicit approval checkpoints before external actions.

When not to use

For short linear tasks with low risk and little branching logic, a single-agent flow can be faster and simpler to maintain.

Failure modes

Common failures include overlapping role scopes, weak handoff contracts, and missing escalation paths. These produce rework loops, inconsistent decisions, and silent quality regressions.

Common questions

What is an agent role? An agent role is a bounded responsibility with clear inputs, outputs, and escalation rules.

Why does role collaboration fail? It usually fails when handoff contracts are vague and no role owns final quality validation.
