Agno now supports TypedDict in addition to Pydantic for defining input schemas in agents, teams, and workflows. This allows developers to specify structured input with explicit key-value types, reducing errors and improving workflow predictability.

**Why this matters:**

- Provides stronger type guarantees for workflow inputs
- Simplifies validation and error handling
- Supports consistent behavior across complex multi-agent workflows

**Who this is for:**

Engineering teams building automated workflows with strict input requirements.
