Three tools with complete schemas and descriptions, but quality is uneven. placid_list_templates has good filtering parameters and clear purpose. placid_generate_image and placid_generate_video have well-structured layer schemas using oneOf for type variants, but descriptions lack context on when to use each tool, prerequisites, or what happens on failure. Parameter descriptions are present but minimal (10-30 chars). No error recovery guidance. Output schema not documented, handlers return text responses but structure is not formally specified. Tool composition is reasonable (list → generate workflow), but descriptions don't guide this.

• Add formal output schema to each tool definition. Document that generate_image/video return {content: [{type: 'text', text: string}]} and list_templates returns {templates: [{id, title, preview_url, layers, tags}]}.
• Expand descriptions to 100-150 chars. For generate_image: 'Generate a static image from a Placid template. First call list_templates to find a template_id, then provide layer content (text or image URLs). Returns image URL on success.'
• Add error recovery guidance to descriptions. E.g., 'If generation fails, verify template_id exists via list_templates and all required layers are provided.'
• Document parameter constraints in descriptions. E.g., 'template_id: UUID format (e.g., 550e8400-e29b-41d4-a716-446655440000)' and 'layers: object with keys matching template layer names'.
• Add pagination to list_templates. Accept optional limit (default 20, max 100) and offset/cursor parameters. Document in description: 'Returns up to 20 templates per call. Use offset to paginate through results.'
