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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description still adds genuine behavioral context: 'deterministic lexical retrieval' tells the agent this is keyword-based rather than semantic matching (affecting query formulation), and the note that research results carry thegeneralaverage.com URLs discloses result provenance.

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?

Front-loaded with the core verb and resource, which is good. However, the mid-sentence catalogue of content types ('industry pillars, vertical insurance guides and FAQs, provider profiles, comparisons, best-of provider rankings...') is a bloated list that pushes the two genuinely informative clauses — lexical retrieval and URL provenance — to the tail.

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?

An output schema exists, so return values need not be explained, and annotations cover the safety profile. The remaining gaps are the absent routing guidance versus a crowded set of sibling search/retrieval tools and the unexplained limit parameter — enough to make this only minimum-viable for a tool in an eight-sibling family.

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% for two parameters. 'query' is self-evident from its name, but the description says nothing about query syntax, and the non-obvious 'limit' constraint (default 5, max 8) that caps result count is left entirely to the schema. The description therefore does not compensate for the coverage gap.

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 (Search) and a well-scoped resource: published Spot pages plus The General Average research content, with concrete content categories enumerated. It is meaningfully distinguishable from narrower siblings like search_provider_reviews or search_provider_reliability, though it never explicitly contrasts itself with them or with ask_spot.

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 when-to-use or when-not-to-use guidance, and no sibling is named as an alternative. The adjective 'published' implies a scope restriction but the agent must infer that ask_spot, search_provider_reviews, or get_page might be better for narrower needs. Implied context only, with no exclusions.

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