Moves Human-in-the-Loop documentation from the Experimental section
to the Tool Use section, as it is a stable feature for tool approval
workflows.
Changes:
- Moved Human-in-the-Loop page to Tool Use section after Tool Variables
- Removed from Experimental section in docs navigation
- Removed experimental warning from human_in_the_loop.mdx
Human-in-the-Loop is now positioned alongside other tool-related
features, making it easier for users to discover when implementing
tool approval workflows.
