- Added centralized error handling for "not found" scenarios in GetChat, UpdateChat, DeleteChat, and GetMessages functions, enhancing user feedback for missing resources.
- Introduced isNotFoundError and respondNotFound utility functions to streamline error responses across chat-related operations.
- Updated the setting package to include new endpoints for setup status and user preferences, improving API functionality and user experience.
Think of Yao Agent as a cage, not an animal. What you put inside determines the behavior; the cage keeps it controlled.
Every request flows through the same pipeline:
Create Hook runs before the executor — inject context, enforce constraints, route requests. Next Hook runs after — validate output, trigger downstream actions, drive multi-step loops. The AI does the heavy lifting. You define the boundaries.
Deterministic logic, routing, menu flows — no AI needed
All three share the same Hook interface. You can mix them freely — route some requests through the LLM, handle others with pure code, all inside a single Create Hook.

About the Name
Yao (爻, yáo) is the fundamental symbol in the I Ching — the building block of the eight trigrams. Like a binary digit, it has two states. Their combinations describe the patterns of everything.
