Short answer: if your agent graph needs more than one level of delegation, Claude Managed Agents can't express it — Anthropic's own docs state the coordinator delegates one level deep only, with depth beyond that silently ignored. Anter's orchestrator supports multi-hop delegation across the graph, with routing bounded by a cycle guard, hop-depth ceiling, and step-budget decay rather than a flat cap.
Where Claude Managed Agents' coordinator model breaks down
Claude Managed Agents ships a coordinator/sub-agent pattern: one root agent assigns work to sub-agents. Per the Claude Platform Docs on multiagent orchestration, that's a hard architectural limit, not a configuration option — "the coordinator can only delegate to one level of agents; depth > 1 is ignored." The roster is also capped at 20 unique agents in multiagent.agents.
That's fine for a flat triage-and-fan-out pattern. It stops working the moment a specialist sub-agent itself needs to consult a further specialist — a common shape once a system grows past a handful of use cases (a support triage agent that hands off to a billing agent, which itself needs to consult a refunds-policy agent, for example).
What Anter does differently
Anter's delegation construct is not depth-limited. A sub-agent can delegate to another sub-agent, which can delegate further, with three independent safety mechanisms instead of a hard depth cap:
- Exact cycle guard — a sub-agent can't be asked to consult a target already in its current call chain.
- Hop-depth ceiling — chains are bounded, but configurably, not fixed at one hop.
- Step-budget decay — each cross-agent hop inherits a reduced step allowance, so cost is bounded by construction as chains grow, not left open-ended.
Every delegation and transfer is validated against a write-time allowlist and a runtime existence check, then persisted as a structured routing event before the next step executes — so the graph is auditable after the fact, not just enforced at call time.
Multi-provider by default
Claude Managed Agents is naturally scoped to Anthropic's model lineup. Anter's orchestration layer is provider-agnostic: OpenAI, Anthropic, Azure OpenAI, and Google models can sit in the same agent graph, so a provider decision doesn't also lock in the routing architecture.
