delete_users_by_id_favorites_by_slug

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

No annotations are provided, and the description only states 'Removes', indicating a destructive action. It does not disclose behavioral aspects such as irreversible effects, required permissions, rate limits, or response behavior. The description fails to compensate for the lack of annotations.

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 description is a single, concise sentence that directly states the tool's action. It is front-loaded and contains no unnecessary words.

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?

Given the tool is a simple delete operation but lacks output schema and annotations, the description provides no information about return values, error conditions, or prerequisites. It is incomplete for an agent to invoke correctly without additional context.

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?

With schema description coverage at 0%, the description adds no meaning to the parameters. It does not explain that 'id' likely refers to user ID, 'slug' to recipe slug, or 'accept-language' is optional. The description is completely insufficient.

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 'Removes a recipe from the user's favorites' uses a specific verb ('Removes') and clearly identifies the resource ('recipe from the user's favorites'). It distinguishes from sibling tools like 'create_users_by_id_favorites_by_slug' (which adds) and 'list_users_by_id_favorites' (which lists).

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 description implies use when wanting to remove a favorite recipe but provides no explicit guidance on when to use this tool versus alternatives, such as other delete tools or conditions like user authorization. It meets the minimum viable for implied usage.

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