Module team 

Available on crate feature agents only.

Portable, validated multi-agent team composition.

A TeamSpec is data: it names members, identifies the coordinator, and declares exact directed relationships. Compilation binds those names to any existing Agent implementations and produces a CompiledTeam root that can be passed directly to a Runner.

BlackboardPolicy

Bounded blackboard execution policy.

BlackboardSpec

Portable, governed shared-transcript team definition.

BlackboardTransition

One exact permitted speaker transition.

CircuitBreakerPolicy

Opens an edge circuit after repeated failures.

CompiledBlackboardTeam

Executable blackboard/group-chat root.

CompiledTeam

Executable root produced by TeamSpec::compile.

RelationshipPolicy

Contract enforced for one exact relationship.

ResolvedTeamMember

Immutable member binding captured when a team is compiled or discovered.

StaticTeamAgentRegistry

Deterministic in-process registry useful for generated projects and tests.

Safe action a durable host can take for a restored execution receipt.

TeamResumePolicy

Recovery contract for a delegation that was running when execution stopped.

TeamRuntimeError
