remove_from_cart

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

Description does not disclose behavior when item not in cart, quantity exceeds available, or any irreversible effects. No annotations provided, so description carries full burden but is insufficient.

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?

Single sentence is efficient but lacks essential details, making it under-specified rather than concise. Could be improved with necessary context.

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?

Output schema exists but description doesn't reference it. Missing info on error handling, return values, and edge cases. Incomplete given low schema coverage and no annotations.

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 0%; no descriptions for 'item_id' or 'quantity'. Description adds no format, validation, or contextual meaning beyond parameter names.

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?

Description clearly states verb 'Remove', resource 'a specific quantity of an item from the cart', which distinguishes it from sibling tools like 'add_to_cart' and 'check_cart'.

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 guidance on when to use this tool over alternatives (e.g., when to remove vs clear entire cart). No mention of prerequisites or exclusions.

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