### Answer Based on the available sources, there isn't a built-in feature to track how many times a specific tool has been called mid-flow and use that count as a transition condition (e.g., "if tool X used more than Y times, transition") . However, you could potentially implement this using a workaround: 1. Use a dynamic variable as a counter – You can create a dynamic variable (e.g.,

{{tool_x_count}}

) and increment it each time the tool is called by having your custom tool endpoint return an updated count value. [(1) ]() 2. Use equation-based transitions – Conversation Flow supports equation-based transitions where you can write conditions like

{{tool_x_count}} > 3

to transition based on variable values. [(2) ]() 3. Store the count in response variables – When defining your custom tool, you can use

response_variables

to capture values from the tool response and store them for use in transitions. [(3) ]() The limitation is that you'd need to manage the counter logic yourself (either in your tool endpoint or by structuring your flow to increment a variable) . I don't have documentation showing a native "tool call count" tracking feature. If this is a critical requirement, you may want to reach out for additional guidance.
