delete_favorite_food

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the description's 'Remove' aligns. It adds value by specifying authentication requirements ('check_auth_status first'), but does not explain behavior for the two optional parameters (serving_id, number_of_units) or elaborate on idempotency beyond the annotation.

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?

Two sentences front-load the purpose and key requirement. No unnecessary words. Could be slightly improved with clearer order or bullet points, but it is efficient.

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?

The description omits many contextual details: optional parameter roles, return values, side effects (e.g., if food is not in favorites), and contrast with similar sibling delete tools. Given three parameters and no output schema, the agent receives insufficient information to use the tool correctly.

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 only 33% (food_id described). The description mentions 'Remove a food' implicitly referring to food_id, but provides no meaning or usage for serving_id and number_of_units. With low coverage, the description should compensate but fails to do so.

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 description clearly states 'Remove a food from the user's favorites' with a specific verb and resource. However, it does not explicitly differentiate from sibling tools like 'delete_favorite_recipe' or 'delete_food_entry', relying on the tool name to imply resource type. This is clear but not fully differentiated.

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?

Only a prerequisite is given ('Requires profile auth'), with no guidance on when to use this tool versus alternatives (e.g., delete_favorite_recipe, delete_food_entry). There is no mention of idempotency or when not to use it, leaving the agent without decision-making context.

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