Agent Designer — Multi-Agent System Architecture

Design, schema-generate, and evaluate multi-agent systems with three deterministic tools. The scripts are the workflow — do not freehand an architecture when the planner can score one from requirements.

When to use

• Designing a new multi-agent system from requirements (pattern choice, roles, comms)
• Generating provider-ready tool schemas (Anthropic + OpenAI formats) from plain tool descriptions
• Evaluating execution logs: success rate, latency distribution, cost, bottlenecks

When NOT to use: Claude Code Workflow-tool automations → workflow-builder; single-agent workflow scaffolds → agent-workflow-designer; multi-agent fan-out at runtime → agenthub.
