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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false, so the safety and idempotency profile is fully covered. The description's only added behavioral signal is that the indexed pages are 'public' (no auth needed). It says nothing about result limits, ranking, or pagination.

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?

One front-loaded sentence with no filler; the verb and scope come first. The trailing enumeration is slightly list-heavy for a tool whose query accepts free text anyway, but nothing is wasted.

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 a one-parameter search tool with a fully annotated safety profile, the definition is minimally sufficient. However, there is no output schema, and the description never characterizes the returned results (page hits vs. structured items), so the agent cannot anticipate what it will receive.

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?

There is a single required parameter with 100% schema description coverage, so the schema already defines 'query' fully. The description only adds that the query may target several entity types, which is marginal clarification rather than new semantic detail. Baseline 3 is appropriate when the schema does the heavy lifting.

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 gives a specific verb (search) plus the resource (public OhGiftPlease pages) and enumerates the searchable content types (product, brand, category, guide, gifting question). It is clear what the tool does, but it does not distinguish itself from siblings such as find_gifts, find_gift_guides, or browse_gift_categories, which cover overlapping content.

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?

There is no explicit when-to-use or when-not-to-use guidance. With six siblings covering adjacent ground (find_gifts, find_gift_guides, browse_gift_categories), the description never says when this broad search should be preferred over a targeted finder, leaving the agent to guess.

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