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

Annotations already declare this a safe, idempotent, non-destructive, closed-world read, so the safety profile is covered. The description adds that each event carries its source page, which is useful return context, but says nothing about result volume, date defaults, or what happens when no filters are supplied.

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 dense sentence front-loads the resource type before the filtering options. It is appropriately sized, with only minor awkwardness in the 'dated:' construction.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. Still, with three all-optional parameters, the description never says what happens when called with no arguments, which is a meaningful gap for an agent deciding whether to filter.

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 0%, so the description carries the burden. It maps reasonably well: 'market' matches the market param, 'since a date' matches since, and 'category or brand' implicitly routes through the free-text query param. However, it never states that query is free-text or what it accepts, leaving the mapping partly ambiguous.

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 resource (recalls, withdrawals and food-safety alerts) with the retrieval scope, so an agent immediately knows this returns enforcement events. It is clearly distinct from the other siblings like get_item, get_price, or verify_gtin, though it never names an alternative explicitly.

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 phrase 'by market, category, brand or since a date' hints at how to narrow results, but there is no statement of when to use this tool versus alternatives and no prerequisites or exclusions. Usage must be inferred entirely.

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