Layer Breakdown

Orchestrator Simulation

How 4 major AI orchestrators evaluate your agent

4/4

would select

69
Selects

LangGraph

Graph-based agent orchestration

↑Schema layer is strong — LangGraph can reliably pass typed parameters between graph nodes.
↓Reliability data unavailable — LangGraph retry logic cannot be tuned for this tool.

Fix: Add async:true and document latency expectations.

70
Selects

CrewAI

Role-based multi-agent delegation

↑Semantic layer is strong — CrewAI agents can infer the tool's role from its description.
↓Schema coverage is thin — structured output parsing may fail in some crew workflows.

Fix: Add required: [] array to parameter schema.

71
Selects

OpenAI Assistants

Function calling via Assistants API

↑Schema is well-defined — OpenAI function calling can serialize inputs correctly.
↓Reliability unknown — Assistants API cannot estimate retry cost for this function.

Fix: Add output schema with type and properties.

69
Selects

AutoGen

Microsoft multi-agent conversations

↑Description is clear enough for AutoGen agents to route conversation turns.
↓Governance signals absent — AutoGen cannot assess tool trustworthiness in multi-agent pipelines.

Fix: Add signing metadata to pass AutoGen's trust filter.

⚠ Simulated thresholds — based on documented selection criteria, not live orchestrator calls.
