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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint, so the safety profile is fully covered. The description adds no behavioral context beyond them — nothing about result shape, result count, ranking, or whether the query is fuzzy or exact — so it earns little credit over the structured data.

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 or repetition, and the core action lands first. It is efficiently sized for a simple search tool.

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 five-parameter read-only search with full schema coverage and annotations covering the safety profile, the description is sufficient to call the tool correctly. The only mild gap is that it says nothing about what a result looks like, but with no output schema this is not required.

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 documents all five parameters with examples. The description restates the same facets (recipient, interest, vibe, occasion, budget) without adding format, precedence, or interaction detail, which is the expected baseline 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 names a specific verb (find) and resource (OhGiftPlease gift ideas) and enumerates the facets it searches over (recipient, interest, vibe, occasion, budget). It is clear on its own, but it does not distinguish itself from closely overlapping siblings such as search_ohgiftplease, get_gift_finder, or browse_gift_categories, which an agent must choose between.

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 guidance, no exclusions, and no named alternative. Given the sibling set contains a general search tool and a gift-finder tool, the agent is left to infer which one to pick, which is a real routing gap rather than a minor omission.

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