Provides a reusable Agent base class that manages chat history, tool calling, context folding (automatic summarization when approaching context window limits), and cost tracking. Demonstrates a clean pattern for building LLM agents with configurable context management and tool integration, easily extractable for other agent-based applications.

Defines a hierarchical data model for presentation shapes (ShapeElement, Picture, TextBox, GroupShape) with closures for editing operations (clone, replace, delete) and HTML conversion. The closure pattern allows deferred execution of edits, enabling undo/redo and ordered application. This module is self-contained and could be reused in any PPTX manipulation project.

Implements DeepPresenterConfig and LLM/AsyncLLM classes with endpoint management, retry logic (using tenacity), response validation, and cost tracking. The configuration pattern supports multiple LLM providers, automatic failover, and structured output parsing. This is a well-crafted, reusable component for any application that needs robust LLM integration with configurable endpoints and retry strategies.

Contains the CodeExecutor class that orchestrates slide editing API calls (replace_paragraph, clone_paragraph, del_paragraph, replace_image, etc.) with retry, history tracking, and error feedback. The pattern of defining a set of atomic operations and executing them in sequence with rollback capability is reusable for any API-driven content generation system.
