28 tools with consistent naming (verb_noun pattern) and basic schemas. Descriptions present but generic (avg ~40 chars, well below 194-char baseline). Parameter descriptions exist but lack constraints, ranges, and format guidance. No output schemas documented. Error handling absent. Missing tool annotations (readOnlyHint, destructiveHint). Composition is sound (single responsibility per tool), but descriptions do not guide LLM selection or explain when to use each tool vs. similar ones.

• Expand all descriptions to 50 - 200 characters. Include WHAT the tool does, WHEN to use it, and any prerequisites. E.g., 'Get metadata for the active presentation (title, slide count, theme). Call this before modifying to confirm the target presentation.'
• Document output schemas for all tools. Specify returned fields, types, and which IDs/references are needed for downstream calls. E.g., list_presentations should return [{id, title, theme, slide_count}] so agents can pass id to open_presentation.
• Add JSON Schema constraints to parameters: use enum for theme_name and layout (enumerate valid values), minLength/maxLength for text fields, minimum/maximum for numeric coordinates and font sizes. Replace format hints in descriptions with formal pattern or enum declarations.
• Add tool annotations: mark get_* and list_* tools with readOnlyHint=true; mark delete_slide, close_presentation (with should_save=true), and export_pdf with destructiveHint=true; mark idempotent tools (e.g., set_presentation_theme called twice with same args) with idempotentHint=true.
• Add error recovery guidance to descriptions. E.g., 'If file not found, call list_presentations to see available files.' For destructive tools, add: 'This operation cannot be undone. Consider calling screenshot_slide first to preserve a record.'
