You have two agents. Agent A analyzes customer data. Agent B generates support tickets based on that analysis. Between them, they're supposed to solve the problem.

Here's what happens in production:

Agent A runs on Claude Managed Agents. It finishes its analysis, returns JSON. Agent B is running on Cursor in your local harness. It never sees Agent A's reasoning, only the JSON. Agent B gets stuck on something Agent A already figured out and decides to re-analyze. You pay twice.

Or: Agent A generates a ticket. Agent B approves and routes it to a third agent. The third agent fails. Now what? Who remembers what happened at step 1? The failure is orphaned — nobody can trace it back to the decision that caused it.

Or: You have an orchestrator agent on Bedrock. It coordinates three specialized agents on three different runtimes. The orchestrator decides Agent 1's answer conflicts with Agent 2's. It asks Agent 2 to reconsider. Agent 2 never gets the context it needs because the orchestrator couldn't thread state across runtime boundaries.

This is the multi-agent coordination crisis. Recent industry data shows 57% of organizations already deploy multi-step agent workflows, 16% have progressed to cross-functional AI agents spanning multiple teams, and 81% plan to expand into more complex agent use cases in 2026. Most of those teams are discovering right now that coordination patterns that work on paper fail in production.

The three emerging coordination patterns are clear:

**Sequential:** Agent A → Agent B → Agent C. One hands off to the next. This fails because:

**Group chat:** Multiple agents discussing a problem together. This fails because:

**Collaborative reasoning:** An orchestrator agent coordinates specialists. This fails because:

The pattern is: **coordination requires shared context, durable state, and cross-runtime visibility. Without infrastructure, teams rebuild this in every agent pair.**

Teams that succeed build:

**Coordination memory**: Every agent call (input, output, reasoning) is logged centrally. When Agent B needs context from Agent A's work, it queries a shared session store, not a prompt.

**Durable handoff**: When Agent A hands off to Agent B, the handoff is a session event, not a message in a prompt. If Agent B crashes mid-work, the orchestrator knows where the handoff was.

**Cross-runtime visibility**: Agents on different runtimes (Claude Managed Agents, Bedrock, Cursor, custom) can query what other agents in the same workflow have done, without passing messages through prompts.

**Audit trail**: Every coordination decision (Agent A says X, Agent B asks for clarification, Agent C approves) is immutable. When coordination fails, you can trace exactly which agent made which decision.

**Per-agent identity in orchestration**: An orchestrator doesn't invoke "the support agent"—it invokes "support-agent-v2-for-customer-123" with specific tools, memory blocks, and approval gates scoped to that invocation.

This is not a framework problem. LangGraph can orchestrate agents. Microsoft Agent Framework coordinates them. But neither can:

These are control-plane problems.

The teams getting multi-agent coordination right are deploying:

When the orchestrator asks Agent B to reconsider, it doesn't pass a prompt. It:

This requires infrastructure that's separate from frameworks.

The industry is shifting rapidly. Single-agent workflows are giving way to coordinated teams of specialized agents working in parallel. Docker's report from AI Engineer World's Fair 2026 documented the emergence of agent-specific disciplines: evals, context engineering, harness engineering, memory, sandbox, platform engineering, and inference. Harness engineering is the new discipline required because frameworks don't provide it.

The problem is urgent because:

Teams that get coordination infrastructure working first will ship faster and cheaper than teams rebuilding it in every orchestrator.

LiteLLM Agent Platform treats multi-agent coordination as a first-class problem. The key features:

This architecture is why the control plane is separate from the data plane. Coordination is stateful, but it happens fast (sub-millisecond per query). You need both: a fast gateway (LiteLLM-Rust) handling agent invocation routing, and a durable control plane (LAP) managing coordination state.

If you're building multi-agent systems, ask:

If the answer to any is "no," you're either rebuilding infrastructure in every orchestrator, or you'll hit scaling walls in month 2.

Coordination patterns are becoming table-stakes. The teams that solve it with infrastructure will win.
