initiate_deep_thinking
AI agents call initiate_deep_thinking to retrieve information from CBT Agent Helper without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though initiate_deep_thinking only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
