add_single_recipe_ingredients_to_list

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It implies mutation via 'add' and the POST verb, and flags deprecation, but says nothing about permissions, side effects on existing list items, or the presence of a request body (recipeIngredients / recipeIncrementQuantity).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The deprecation and endpoint are front-loaded, which is good, but the 'Keywords:' block is a long list of near-duplicate search terms (create/add/new/make/write recipe) that bloats the definition without adding meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a mutating tool with no annotations, no output schema, and 0% parameter documentation, so the description should do more work. It names the endpoint but omits request body structure, permissions, and the deprecation replacement, leaving the agent under-informed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 3 parameters, and the description adds no meaning for item_id, recipe_id, or the optional body. The keyword block ('post', 'create') adds noise rather than parameter guidance, so it fails to compensate for the coverage gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The title/name phrase 'Add Single Recipe Ingredients To List' gives a specific verb+resource, and the bracketed POST path pins down the exact endpoint and its two path params. However the body line 'Create recipe' contradicts the add-to-list purpose and the description never distinguishes this single-recipe variant from the sibling add_recipe_ingredients_to_list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The '(DEPRECATED)' marker is the only usage signal, and it is not followed by a named replacement such as add_recipe_ingredients_to_list, so an agent is told to avoid the tool but not what to use instead. No context on when adding a recipe's ingredients to a list is appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
