openai/gpt-chat-latest → A (9:1)

Side A adds a substantial new `reddit.rs` module implementing a reusable Reddit API client with rate limiting, HTTP request handling, structured serde models for posts/comments, custom deserializers, and helper methods for extracting typed data. Side B improves documentation by aligning the DSL and API identity conventions (removing `@` from wire formats, updating CLI examples, and clarifying bearer/delegate behavior), but it does not change runtime behavior or project capabilities.
