Develop Tool Integration for Zapier and Kore.ai

Elaborate on the `CustomZapierTool` and `CustomKoreAITool` by implementing methods that simulate interaction with Zapier Interfaces (e.g., receiving webhook data or sending parsed data to a Zapier workflow) and Kore.ai (e.g., triggering a custom alert flow based on detected negative brand sentiment). Demonstrate how the `PromptMonitor` agent would use the Zapier tool to fetch new prompts and how the `BrandAnalyzer` would decide to trigger a Kore.ai workflow when a significant negative sentiment trend is identified. Ensure these tools are properly exposed to the respective agents in CrewAI.
