The server implements 5 tools with complete input schemas and descriptions, but several tools have generic or incomplete parameter documentation, and output schemas are not formally documented. Tool names follow verb_noun conventions well. Error handling is functional but lacks recovery guidance. List tools use consistent pagination patterns. No security concerns detected (API key properly injected via environment variable, no secrets in parameters). Overall, the server is functional but falls short of production-grade quality due to incomplete parameter documentation and missing output schema specifications.

• Document each complex parameter's internal structure. For text_options, image_options, card_options, and sharing_options, add parameter descriptions like: 'A dictionary containing configuration keys specific to [purpose]. Supported keys: [key1] (type), [key2] (type), ...'
• Add formal output schema documentation to tool descriptions. Specify what fields are returned by generate_presentation and create_from_template when successful (e.g., generationId: str, status: str, url?: str, created_at?: str).
• Define enum constraints for the 'format' and 'text_mode' parameters. Update descriptions to list valid options (e.g., 'format: one of "presentation", "document", "slide"').
• Enhance error messages in _request_json to be recovery-focused. Instead of 'Gamma request failed (400): ...', return 'Invalid request (400). Check that all required fields are provided. If the problem persists, verify your API key and try again.' or 'API temporarily unavailable (503). Retry in a few seconds.' for retryable errors.
• Add min/max constraints for numeric parameters. For num_cards, suggest: 'Number of cards to generate (1-100, default 10)'. For max_wait_seconds, suggest: 'Maximum time to wait for completion in seconds (1-600, default 180)'.
• Add parameter descriptions for limit and after in list_themes and list_folders. E.g., 'limit: Maximum number of results to return (1-100, default: server-determined)' and 'after: Opaque pagination cursor from a previous response. Use to fetch the next batch of results.'
