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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered; the description adds real value by disclosing the return shape (ranked styles, a reason each) and that fulfillment happens via partner retailer links rather than in-tool checkout. It doesn't mention limits on result count or any failure modes.

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 sentences, input contract first then return contract, with no filler. The parenthetical efficiently enumerates the content the query should contain, and every clause contributes information.

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 no output schema, the description usefully summarizes what comes back. However, it omits any guidance on count (default 3, max 6) or the avoid filter, both of which an agent needs to invoke the tool accurately, leaving meaningful gaps for a 4-parameter tool.

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 must carry parameter meaning, and it only partially does. It explains the query string well (who/occasion/interests/diet/budget in one sentence) and gestures at budget, but it never mentions the avoid or count parameters, and folding 'budget' into the query text while a separate budget parameter exists is potentially confusing.

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 names a specific action (match a described recipient to gift basket styles) and a concrete output (styles with a reason each plus buy links), so the resource is unambiguous. It doesn't explicitly distinguish itself from the similarly-named scarf_concierge sibling, but gift baskets vs. clothing accessories is clear from the text.

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?

It tells the agent exactly how to formulate the invocation: one sentence covering who, occasion, loves, dietary needs, and budget. There are no explicit exclusions or named alternatives (e.g., shop_search or scarf_concierge), so it stops short of full routing guidance.

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