OpenAI's response_format requires a 'name' for json_schema definitions.
This change enables custom schema names which are useful for debugging,
logging, and clarity when using multiple schemas.
Supports two formats:
1. Full: { name: 'custom_name', schema: { type: 'object', ... } }
2. Schema only: { type: 'object', ... } - defaults to 'response'
Changes:
- Updated OpenAI provider to extract schema name from wrapper format
- Added unit tests for schema name functionality
- Maintained backward compatibility (plain schemas default to 'response')
Related to schema naming discussion for better debugging and observability.
Previously, Chat#with_schema extracted only the [:schema] portion from
RubyLLM::Schema objects, discarding the class name. Now it preserves the
full hash, allowing schema class names to be automatically used in OpenAI API.
Changes:
- Updated Chat#with_schema to keep full to_json_schema result
- RubyLLM::Schema classes now automatically use their class name
- Added test for RubyLLM::Schema format with class name
- Manual wrappers and plain schemas still work as before
Example:
class PersonSchema < RubyLLM::Schema
string :name
integer :age
end
chat.with_schema(PersonSchema)
# OpenAI API receives: name: 'PersonSchema' (instead of 'response')
Documents the new custom schema name feature in the structured output section, explaining how to use the full format with custom names and when they're useful (influencing model behavior and debugging). Also adds a note in the RubyLLM::Schema section explaining that schema classes automatically use their class name in API requests. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
