Users building agentic pipelines with Hermes models in Ollama report an issue where the model correctly generates tool call JSON in its response but the actual tool functions are never invoked or executed. This typically stems from the framework or integration code not being configured to parse and dispatch the model's tool call output, meaning the JSON is treated as plain text rather than triggering the corresponding function. The discussion likely covers diagnosis, common misconfigurations, and potential fixes for closing the loop between tool call generation and execution.
