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

With no annotations, the description carries the full behavioral disclosure burden. It transparently states the key boundary—never clicking the final purchase button—and describes the actions it takes. It does not cover other behaviors like authentication or side effects, but the most critical safety trait is well disclosed.

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 concise, front-loaded with the primary action, and followed by a crucial safety note. The bilingual repetition is not wasteful, and every sentence serves a purpose.

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?

The description covers the core actions and the safety boundary, but it misses the purpose of the site parameter and any prerequisites or return behavior. Given the lack of annotations and output schema, more context would be beneficial for full completeness.

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?

The schema already documents ids, and the description adds minimal context beyond that these are items to add to cart. However, the optional site parameter is entirely undocumented in the schema and unmentioned in the description, leaving a significant parameter semantic gap.

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 tool adds items to cart and opens the review page, using specific verbs and resources. It also explicitly differentiates itself by noting it never clicks the final purchase button, which distinguishes it from purchase-completion tools.

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 usage after chatbuy_search by referencing product IDs from that tool. It gives clear context for when to use it (for review before purchase) and imposes a safety boundary, but it does not explicitly name alternatives or exclusion criteria.

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