State Synchronization in Multi-Agent Graph Architectures

Multi-agent swarms operate concurrently. Without synchronization, agents can write conflicting updates to customer records.

1. Concurrency Bottlenecks

When the Account Agent and Billing Agent execute mutations simultaneously, records risk entering race conditions.

2. Graph State Machine

We implement lock indicators inside the session context. Before an agent mutates a record, it acquires a temporary write token.

# Python agent write token lock check
def mutate_record(session_id, data):
    if acquire_lock_token(session_id):
        commit_db_mutation(data)
        release_lock_token(session_id)
    else:
        schedule_retry(session_id, data)

3. Boundary Safety Checks

Strict boundary safety keeps systems secure, preventing overlapping loops and ensuring safe, predictable outcomes.
