remove_from_cart

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

With no annotations provided, the description carries full burden and does well by disclosing critical behavioral constraints: it only affects local tracking, cannot modify the actual Kroger cart, and requires user action for real removal. It also describes the return value format. It doesn't cover potential errors or side effects, keeping it from a perfect score.

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 efficiently structured with clear sections: purpose statement, important limitation, usage guidelines, parameters, and return value. Every sentence earns its place, and critical information is front-loaded with the 'IMPORTANT' warning.

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 mutation tool with no annotations and no output schema, the description provides strong context about behavior, parameters, and returns. It could slightly improve by mentioning error cases or confirming no side effects beyond local tracking, but it's largely complete for its complexity.

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 0% schema description coverage, the description fully compensates by explaining both parameters: product_id identifies what to remove, and modality specifies which instance (with clarification that 'None' removes all). This adds essential meaning beyond the bare schema.

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 the specific action ('Remove an item from the local cart tracking only') and distinguishes it from siblings by explicitly contrasting with actual cart removal in the Kroger app/website. It avoids tautology by explaining the limited scope beyond just the tool name.

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 provides explicit when-to-use criteria (two numbered conditions) and when-not-to-use warnings (cannot remove from actual cart). It distinguishes from siblings by clarifying this is for local tracking sync only, not actual cart operations.

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