Create and edit Lark Office slides with XML protocol, supporting presentation creation, page management, and content modification.

• Supports three creation workflows: one-step creation for simple slides, two-step creation (empty presentation + page-by-page addition) for complex content, and block-level editing of existing pages without reordering
• Handles slide operations including create, read, delete, and replace at both presentation and individual page levels; automatically parses /slides/ and /wiki/ URLs to extract presentation tokens
• Requires planning layer (slide_plan.json) before XML generation for new presentations or major rewrites; includes visual planning (layout_type, visual_focus, text_density) and asset planning with fallback strategies
• Enforces strict XML validation: text must use <content><p>...</p></content>, images require uploaded file_tokens (no external URLs), and all complex content undergoes post-creation verification against validation checklist
• Provides template search, summarization, and extraction via template_tool.py to avoid boilerplate; prioritizes user identity (--as user) for personal content operations
