Critical gaps across all dimensions. Tool 'addTwo' is a placeholder with no description and trivial functionality. Three Google Forms tools (create_form, add_question, submit_form_response) have descriptions but lack parameter type definitions in visible schema, only inferred from docstrings. No output schemas documented. Parameter descriptions are present but incomplete (e.g., 'choices' lacks format/constraint details). No error handling guidance. Credentials hardcoded in source (CLIENT_ID, CLIENT_SECRET, REFRESH_TOKEN) violates secret injection pattern. Tool composition is reasonable but descriptions do not guide LLM selection or explain when to use each tool.

• Remove 'addTwo' tool entirely or replace with a real Google Forms operation.
• Move CLIENT_ID, CLIENT_SECRET, REFRESH_TOKEN to environment variables. Load via os.getenv() with validation. Never commit secrets to source.
• Document output schema for each tool. Example: create_form returns {form_id: string, edit_url: string, responder_uri: string}.
• Add enum constraint to 'question_type' parameter: ['TEXT', 'PARAGRAPH', 'MULTIPLE_CHOICE', 'CHECKBOX', 'DROPDOWN']. Wrap in JSON Schema enum field.
• Wrap exception handling with actionable messages. E.g., 'Failed to create form: {error}. Verify credentials are valid and Google Forms API is enabled in your GCP project.'
