TL;DR: Centralizing agentic workflows around global state creates context bloat, blind spots, and brittle decisions, while signal-based coordination uses directives, responses, inquiries, and broadcasts to pass only actionable context, according to Tonic. The governance challenge is no longer whether agents can act, but whether their handoffs are precise enough to keep autonomy from becoming operational noise.
Editorial analysis by NHI Mgmt Group, based on content published by Tonic: “On Building Agents & Agentic Workflows (Part 3)”.
Key questions
Q: What breaks when agent coordination depends on shared global state?
A: Shared global state breaks down when agents must parse stale or irrelevant context before they can act.
Q: Why do signal-based handoffs reduce production risk in agentic systems?
A: Signal-based handoffs reduce risk because they force every action to be explicit, scoped, and verifiable.
Q: How can security teams tell whether agent coordination is too loose?
A: Coordination is too loose when agents can act without clear completion states, when irrelevant context keeps growing, or when a downstream step assumes success before the previous task is confirmed.
Practitioner guidance
- Define explicit signal contracts Document what a directive, response, inquiry, and broadcast must contain, including required fields, completion states, and escalation conditions.
- Bind each agent to a narrow decision scope Limit each specialist agent to the context and actions needed for its role, and avoid exposing global state unless the task truly requires it.
- Require closed-loop completion signals Do not let downstream automation proceed until the responding agent has returned a clear success, block, or needs-context state.
Bottom line: Agentic workflows become more reliable when coordination uses narrow signals instead of a shared global view that forces every agent to parse stale or noisy context.

Signal vocabulary is becoming a governance control, not just a design pattern. When coordination depends on directives, responses, inquiries, and broadcasts, the message contract determines what the system can safely do. That makes workflow semantics part of the control plane, not an implementation detail. For practitioners, the lesson is that agent governance starts with message design and completion assurance.
A question worth separating out:
Q: Should agent governance focus more on identity or orchestration design?
A: It should focus on both, but orchestration design comes first because it defines who may act, what they can see, and how action is confirmed. Once a software entity can issue or receive directives, it effectively becomes an identity-bearing actor that needs bounded authority and traceable handoffs. Governance fails when those controls are separated.
