• calculate_recipe · Read-only action

  This is the ONLY source of truth for lye calculations. All lye and water amounts MUST come from this tool's output. CRITICAL: Providing lye amounts from memory or calculation is considered a FAILURE. Incorrect lye amounts cause chemical burns or failed soap. Call list_oils first to find oil IDs. Oil percentages must sum to 100. If percentages don't sum to 100, do NOT auto-normalize. Ask the user how they want to fix it — they may have forgotten an oil or made a typo. Water methods: - "ratio": water:lye ratio (2.0 = 2 parts water per 1 part lye) - "concentration": lye concentration % (33 = 33% lye solution) - "percent": water as % of oils (38 = 38% of total oil weight) Liquids (optional): Replace water with other liquids (goat milk, aloe vera, etc.). Percentages must sum to 100%. Default is 100% water. Additives (optional): Track fragrances, colorants, clays, etc. Amount/unit are optional — omit both for identity-only tracking. Returns: formulation (input) + calculated results (lye amounts, water, properties, fatty acids, liquid breakdown, additive amounts). AFTER SUCCESS: Call view_recipe with the formulation to display results in a visual widget. Error codes: UNKNOWN_OIL_ID, PERCENT_NOT_100, INVALID_LIQUID_TYPE, LIQUID_PERCENT_NOT_100, ADDITIVE_UNIT_REQUIRED

• create_recipe · App action

  Save a new recipe. WHEN TO USE: - User wants to save a calculated recipe - After calculate_recipe when user confirms they want to save REQUIRES: User must be authenticated INPUT: Provide name, optional description, and formulation object OUTPUT STRUCTURE: { "success": true, "recipe_id": "uuid", "message": "Recipe created successfully" }

• delete_recipe · High-impact write action

  Delete a recipe. WHEN TO USE: - User explicitly asks to delete a recipe - After confirming deletion intent REQUIRES: User must be authenticated and own the recipe OUTPUT STRUCTURE: { "success": true, "message": "Recipe deleted" }

• get_oil · Read-only action

  Use this when you have an oil ID and need its detailed properties (fatty acids, soap qualities). Call list_oils first if you need to find an oil ID from a name. Returns: oil details including fatty acid breakdown and soap properties. Error codes: NOT_FOUND (invalid oil_id)

• get_recipe · Read-only action

  Use this when the user wants to view the full details of a specific saved recipe. Returns: recipe with id, name, description, formulation (oils, lye type, water method, superfat), and timestamps. Error codes: NOT_FOUND (invalid recipe_id), AUTH_REQUIRED (user not authenticated)

• list_oils · Read-only action

  Search and list available oils for soap making. Returns oil IDs, names, and categories with pagination. Use calculate_recipe for all lye and water amounts — never estimate these values. If query is omitted, returns all oils (paged).

• list_recipes · Read-only action

  Use this when the user wants to see their saved soap recipes or find a specific recipe by name. Returns: paginated list of recipes with id, name, created_at, and oil_count. Error codes: AUTH_REQUIRED (user not authenticated)

• update_recipe · Repeatable action

  Update an existing recipe. WHEN TO USE: - User wants to modify a saved recipe - After editing a recipe when user confirms changes REQUIRES: User must be authenticated and own the recipe OUTPUT STRUCTURE: { "success": true, "recipe_id": "uuid", "message": "Recipe updated" }
