283-295: Clarify that defaults are Pydantic-specific; address the dataclass/TypedDict gap.Line 256 indicates that dataclasses, TypedDicts, and Pydantic models all work for structured responses, but your defaults section only demonstrates Pydantic's
Field(default=...). This leaves users uncertain whether defaults are supported for dataclasses (viafield(default=...)) or TypedDict.Since the PR objectives emphasize documenting automatic support through Pydantic, consider either:
- Explicitly note that defaults via
Field(default=...)are Pydantic-specific, or- Show equivalent patterns for dataclasses if they're also supported
Add a sentence after line 294 to clarify scope:
Fields with default values are automatically marked as optional (not included in the `required` list), so users can accept the default or provide their own value. + +**Note:** Default values via `Field(default=...)` are supported specifically for Pydantic models. If using dataclasses or TypedDicts, use `field(default=...)` or equivalent patterns.
296-316: Add a comment explaining Field() vs. simple assignment in Pydantic.Your code example correctly uses
Field(default=..., description=...)but new users may wonder why you're not using simple assignment likepriority: Priority = Priority.MEDIUM. Clarify thatField()is used when you need to attach metadata (likedescriptionfor the form label) along with the default value.Add an explanatory comment to the model definition:
class TaskDetails(BaseModel): title: str = Field(description="Task title") description: str = Field(default="", description="Task description") + # Field() allows us to attach metadata like 'description' alongside the default value priority: Priority = Field(default=Priority.MEDIUM, description="Task priority")Alternatively, add a note after the code block explaining this distinction.
315-317: Add expected behavior and next steps to complete the section.The section ends without explaining the expected user experience: how clients display these defaults, what happens if a user modifies a default value, or where to go next. Per coding guidelines, sections should end with next steps or related information.
Add context after the code example (after line 316):
When you provide a default value, the client will pre-populate the form field with that value. Users can either accept the default and submit, or modify it to provide their own input. This reduces friction for common scenarios. **Next:** Learn about gathering information progressively with [Multi-Turn Elicitation](#multi-turn-elicitation).This gives users clarity on behavior and guides them to the next relevant section.

Adds tests and documentation for SEP-1034 default values in elicitation schemas. FastMCP automatically supports this via Pydantic's Field(default=...) - no code changes needed.
Closes #2544
