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

Annotations already declare readOnly, idempotent, non-destructive and closed-world semantics, so the safety profile is covered. The description adds genuinely new behavior: results are relevance-ranked ('best matches first') and each result carries its intended use, which matters since there is no output schema. Pagination and empty-result behavior remain undisclosed.

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 compact sentences, front-loaded with the action and scope. There is mild redundancy between 'what the meme is used for (intent)' and the closing 'each with what it is used for', but nothing is wasted overall.

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 and only three parameters, the description covers the essentials: what is searched, in which languages, how results are ordered, and what each result contains. It stops short of explaining result-set sizing or how 'limit' bounds the response, which would complete the picture.

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 67%: query and animated are documented in the schema, while limit has no description anywhere. The description adds the intent/'what the meme is used for' search dimension and notes Spanish or English input, which slightly extends the schema's 'any language' phrasing, but the limit parameter stays opaque.

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 and resource ('Search the Meme Studio catalog') plus the three search axes: name, keywords and intent, with multilingual coverage and relevance ordering. The search-vs-lookup distinction against siblings like get_template and popular_templates is inferable but never stated 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?

Usage is implied: this is the tool for finding a template when you have a joke, situation or name in mind. There is no explicit when-to-use vs. when-not guidance and no routing to get_template (single fetch) or popular_templates (browse without a query).

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