Empty cart

clear_cart
DestructiveIdempotent

Remove every product from the cart in one step with the site's remove-all action and confirm the cart is empty. Use only when the user asks to clear the whole cart.

Instructions

Remove every product from the cart in one step, with the website's own "remove all" action, and confirm the cart is empty. Only when the user asks to empty or clear the whole cart; pass confirm: true. To remove some products, use remove_cart_item. If the result has mutation.outcome "unknown", the cart may have changed: call get_cart before any further change and never repeat the request automatically.

A4.5/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is known; the description goes beyond them by noting the site's own 'remove all' action, the post-condition (cart confirmed empty), and a non-obvious failure protocol — on mutation.outcome 'unknown', re-read with get_cart and never auto-retry. That unknown-outcome guidance is genuinely valuable operational context, though it stops short of stating irreversibility or auth requirements explicitly.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tightly packed sentences: action and effect first, eligibility and alternative second, failure handling last. Every sentence carries distinct, actionable information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter destructive action with an output schema available, this covers what the agent needs: when to call, the confirmation gate, success post-condition, and the ambiguous-outcome path. Return-value detail is correctly left to the output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the single parameter already documents itself as a required const true gate. The description's 'pass confirm: true' restates the schema rather than adding new meaning, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource with scope: 'Remove every product from the cart in one step' plus confirmation that the cart is empty. It explicitly distinguishes itself from the partial-removal sibling by naming remove_cart_item, so an agent can route correctly without opening either schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit when-condition ('Only when the user asks to empty or clear the whole cart'), a required argument reminder, and the named alternative for the other case ('To remove some products, use remove_cart_item'). It also supplies a recovery rule for the ambiguous-outcome case, so no condition is left to inference.

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