11 tools with complete schemas and descriptions. Naming follows verb_noun pattern consistently (login, list_recipes, get_recipe, create_recipe, update_recipe, delete_recipe, list_pumps, list_ingredients, set_ingredient_in_bar, list_categories, list_glasses). Descriptions are present and substantive (avg ~120 chars), explaining WHAT and WHEN. All parameters have type definitions and descriptions. However, several critical gaps: (1) No output schemas documented, LLMs cannot predict response structure for chaining; (2) No pagination limits stated in descriptions despite list_recipes accepting page/limit params; (3) No error handling guidance, tools return raw API errors without recovery hints; (4) Token parameter marked optional but fallback behavior not clearly explained in tool descriptions (only in server instructions); (5) No enum constraints on string parameters like 'fabricable' (accepts 'all', 'true', 'false') or 'order_by'; (6) Destructive operations (delete_recipe) lack confirmation/dry-run pattern; (7) Recipe write tools require complex nested schema (categoryIds, stepIngredients with ingredientId/ingredientType) but no schema validation examples provided.

• Document output schemas for all tools. E.g., list_recipes returns {recipes: [{id, name, owner_id, ...}], total: int, page: int}. Include field types and meanings.
• Add enum constraints to string parameters: fabricable: enum=['all', 'true', 'false'], order_by: enum=['name', 'created', 'updated'] (or actual valid values from API).
• Provide a JSON Schema example or template for recipe_json parameter in create_recipe and update_recipe. Show required fields, nested structure, and valid ingredientType values.
• Add error recovery hints to tool descriptions. E.g., get_recipe: 'If recipe not found, call list_recipes() to discover valid recipe IDs.'
• Implement confirmation pattern for delete_recipe: add a 'confirm' boolean parameter (default false) or return a confirmation request via MRTR (Multi Round-Trip Request) pattern.
