Remove a product from the cart

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered. The description adds only the notion of removing a *quantity*, and says nothing about what happens when count exceeds the cart quantity, whether the call errors or partially removes, or what state the cart is left in.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though the brevity reflects under-specification as much as tight writing.

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?

For a destructive, non-idempotent mutation with no output schema and one undocumented parameter, the description is too thin. It should indicate error/partial-removal behavior and the resulting cart state, neither of which is available anywhere else in the structured data.

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 coverage is 50%: product_id is documented in-schema, count is not. The word 'quantity' in the description maps loosely to count and clarifies that removal can be partial rather than whole-line, but it gives no default, bounds, or behavior for counts above what's in the cart.

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?

States a specific verb and resource (remove a quantity of a product from the cart), which is clearly distinct from add_to_cart and clear_cart by name and text. It does not explicitly contrast itself with siblings such as remove_recipe_from_cart or clear_cart, so it stops short of full differentiation.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives (e.g. use clear_cart to empty the cart, or remove_recipe_from_cart for recipe-based items). The agent must infer from the name alone that this is for partial/line-item removal.

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