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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds useful scope about what the response contains, but with an output schema present that information is largely duplicated rather than revealing non-obvious behavior (e.g. caching, rate limits, refresh semantics).

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?

Two dense sentences with no filler; the payload description is front-loaded and the input provenance follows. Slightly run-on, but every clause earns its place.

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?

With annotations covering safety, an output schema covering returns, and 100% param coverage, the description supplies the remaining missing piece (where the url originates). Nothing essential is absent, though it could note sibling alternatives 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?

Schema coverage is 100% and the param is self-documenting, so baseline would be 3. The description adds provenance beyond the schema by naming the two specific sibling tools whose products[].url field should populate it, which helps the agent construct a valid value.

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 verb-resource ('Full Burberry product detail for one product page') and enumerates the exact contents returned (name, sku, colour, material, description, price, stock status, images, colourways). This clearly separates it from burberry_search/burberry_category, which it names as its input source.

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?

Tells the agent where the required url comes from ('burberry_search's or burberry_category's own products[].url field'), which is genuine routing guidance. It stops short of naming when NOT to use this tool versus siblings like burberry_related, but the entry conditions are clear.

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