 In certain cases, you might want to modify the output of the tool-agents before returning it to the central agent. This may be useful if you want to:
 
-- Extract a specific piece of information (e.g., a JSON payload) from the sub-agent's chat history.
-- Convert or reformat the agent’s final answer (e.g., transform Markdown into plain text or CSV).
-- Validate the output or provide a fallback value when the agent’s response is missing or malformed.

 The `is_enabled` parameter accepts:
-- **Boolean values**: `True` (always enabled) or `False` (always disabled)
-- **Callable functions**: Functions that take `(context, agent)` and return a boolean

 Disabled tools are completely hidden from the LLM at runtime, making this useful for:
-- Feature gating based on user permissions
-- Environment-specific tool availability (dev vs prod)
-- A/B testing different tool configurations
-- Dynamic tool filtering based on runtime state
