Tool/function calling coordination and agent orchestration complexity

7

Configuring when, how, and in what order agents invoke tools is the top agent orchestration challenge (23.26% of issues). Developers struggle with disabling/sequencing parallel tool use to avoid conflicts and managing control flow in complex workflows.
