The PPT-MCP server defines 6 tools with partial schema coverage and inconsistent description quality. Three tools (create_presentation, read_presentation, analyze_presentation) have complete JSON schemas and descriptions; however, edit_presentation lacks full schema documentation for its nested 'content' object, edit_presentation_enhanced mixes English and Chinese descriptions creating clarity issues, and edit_presentation_advanced has a Chinese description that is inaccessible to English-speaking LLM agents. Parameter descriptions exist but are generic ('Content to add based on operation type'). No tool provides output schema documentation, making downstream composition risky. Error handling exists in implementation (try-catch with error messages) but lacks structured error classification or recovery guidance. Naming follows verb_noun convention (good) but tool proliferation suggests multiple overlapping responsibilities: three separate edit tools (edit_presentation, edit_presentation_enhanced, edit_presentation_advanced) with unclear differentiation create selection ambiguity for LLMs. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present.

• Consolidate the three edit tools (edit_presentation, edit_presentation_enhanced, edit_presentation_advanced) into a single edit_presentation tool with a comprehensive operation enum, or clearly document when each should be used in descriptions.
• Translate edit_presentation_advanced description to English and clarify which library (pptxgenjs vs pptx-automizer) is actually used. Currently tool descriptions reference conflicting backends.
• Document complete output schemas for each tool. Example for create_presentation: { 'type': 'object', 'properties': { 'file_path': { 'type': 'string' }, 'slides_created': { 'type': 'number' } } }.
• For edit_presentation, split the untyped 'content' object into operation-specific parameters or constrain it with strict property definitions and required fields per operation type.
• Add tool annotations: mark read_presentation and analyze_presentation with readOnlyHint: true; mark create_presentation, edit_presentation, edit_presentation_enhanced, edit_presentation_advanced with destructiveHint: true (they write files).
• Enhance error messages with recovery guidance. Instead of '❌ Failed to create presentation: <error>', return structured error with actionable next steps: { 'error': 'InvalidPath', 'message': 'Output directory does not exist', 'suggestion': 'Ensure directory exists or use a valid path like ./output/' }.
• Add slide_range parameter validation hints to read_presentation (e.g., 'start and end must be between 1 and total_slides; if omitted, all slides are returned').
