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

With no annotations, the description carries the burden and does well by disclosing the metadata-only anti-dump design, the trust block components (authority_tier/fidelity/license + display_grade), and referencing server instructions. It omits details like rate limits or error behavior, but for a read-only search tool the disclosed behavior is substantial.

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?

The description is compact and front-loaded with the primary purpose. It uses three sentences to convey purpose, search behavior, return structure, and a follow-up pointer. Dense but every clause adds value; the only minor issue is one long sentence that could be split for readability.

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?

The tool has an output schema, so return values are externally defined. The description adds context about the anti-dump design, trust block, and follow-up workflow, making it well-rounded. It lacks explicit sorting/pagination details, but those are not critical for a search tool of this scope.

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?

Despite 0% schema coverage, the description adds meaning to q (tokenized AND matching) and category (optional exact filter with concrete examples). The limit parameter is not mentioned, but the schema already provides a default, and its semantics are simple. The critical parameters are well explained.

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 starts with 'Search the source-verified pet regulatory & health topic whitelist', providing a specific verb and resource. It clearly distinguishes itself from siblings by noting it returns metadata only and directs users to get_topic_context for full text, making its unique role explicit.

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 gives clear context: this is a free-text search over topics, and it explicitly recommends a follow-up with get_topic_context(topic_id) for full details. However, it does not explicitly state when not to use this tool versus other siblings like search_pet_recalls, so it stops short of full exclusion guidance.

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