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

No annotations are provided, so the description carries the full behavioral burden. It reveals that three datasets are compared in one call, but omits whether it is read-only, what the output looks like, or what happens when no records are found.

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. The bracket tag and core action are stated immediately, making it efficient and easy to parse.

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 an aggregator tool with no annotations and no output schema, the description is thin. It does not explain return format, data source scope (e.g., Taiwan-only), or how to interpret results, leaving the agent under-informed about what to expect.

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 description coverage is 100%, so the schema already defines the single 'name' parameter. The description reinforces that it accepts a product or brand name but adds no format details, examples, or constraints beyond the 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?

States a specific action (compare three datasets and check for records) and the resource (product or brand safety records), naming the three datasets it cross-references. It does not explicitly contrast with the sibling tools that fetch those datasets individually, but the aggregation intent is clear.

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 or alternative recommendations are provided. It does not say whether to prefer this over calling get_drug_recalls, get_food_ad_violations, and get_international_food_alerts separately, nor does it mention prerequisites or exclusions.

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