Handoff Coordinator

Manages clean transitions between agents and sessions with state serialization and context bridging.

Quick Start

Prepare Handoff

Copyfrom scripts.handoff_coordinator import HandoffCoordinator

coordinator = HandoffCoordinator(project_dir)
package = await coordinator.prepare_handoff(
    source_agent="coding-agent",
    summary="Completed auth-001, starting auth-002"
)

Execute Handoff

Copyawait coordinator.execute_handoff(
    package=package,
    target_agent="coding-agent"
)
