Server has 7 tools with basic descriptions and partial schemas. Naming follows verb_noun convention (list_, get_, render_, measure_, wrap_, fit_). However, critical gaps exist: parameter descriptions are minimal or absent (e.g., 'filter' in list_templates has empty properties and no guidance on what to filter by); output schemas are not documented anywhere in the provided code; error handling is not visible; no indication of pagination support for list_templates despite a 609-template catalog. The render_meme tool accepts complex nested objects (spec.textBoxes, spec.output) but provides no guidance on required vs optional fields, constraints, or expected structure. Text manipulation tools (wrap_text, fit_text, measure_text) lack detail on font availability, fallback behavior, and dimension units. Overall, definitions are skeletal, sufficient for basic discovery but insufficient for reliable LLM-driven composition.

• Document output schemas for all 7 tools. Example: list_templates should return {templates: [{id, name, width, height, category}], total_count, has_more}. This enables LLM chaining.
• Add detailed parameter descriptions. For list_templates.filter, specify: 'Filter by category (string), width (number), height (number), or tags (array). All filters are optional and combined with AND logic.' For render_meme.spec, document required fields: template (required, string), textBoxes (required, array of {text, x, y, fontSize, fontFamily}), output (required, {path, format, width, height}).
• Implement pagination for list_templates. Add limit (1-100, default 20) and offset (default 0) parameters. Return total_count and has_more in response. Document: 'Call repeatedly with offset += limit to fetch all 609 templates.'
• Add error handling guidance. For render_meme, document: 'Returns 400 if template not found (call list_templates to discover valid IDs), 400 if textBoxes exceed image bounds (call measure_meme first to validate layout), 500 if font not available (fallback to system default).'
• Specify font availability and fallback behavior. For wrap_text/fit_text/measure_text, document: 'fontFamily accepts system fonts (Arial, Helvetica, Courier) or web fonts (Anton, Impact). If unavailable, falls back to sans-serif. Dimension units are pixels.'
• Add constraints to numeric parameters. For wrap_text: width (1-4000 pixels), height (1-4000 pixels), fontSize (1-500 pixels). For fit_text: minFontSize (1-100), maxFontSize (10-500, must be >= minFontSize).
