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

The annotations already establish read-only and closed-world behavior, so the description's main added value is that results include prices in rand and item ids usable by estimate and request_order. It still does not explain result ranking, pagination, or how max_results affects the 'search everything' scope.

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: it states the search scope and pricing first, then the return value. Every clause carries useful information without repetition.

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 three-parameter search tool with no output schema and sparse schema descriptions, the definition covers purpose, pricing, and return ids adequately. It remains incomplete on parameter behavior, result limits, and how this search relates to get_item or list_guides.

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 only 33%, so the description should compensate, but it does not explain how query matching works, how category filtering is applied, or what max_results controls. Listing offering types is not the same as explaining the category parameter's semantics.

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 states a specific verb and resource: search Alpha Flow Tech's full catalog, with prices in South African rand. It names the covered categories and says it returns item ids for estimate and request_order, which makes the tool's role concrete.

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?

The phrase 'Returns item ids for estimate and request_order' implies the intended discovery-before-ordering workflow. However, it does not explicitly say when to use this instead of get_item or list_guides, and it gives no exclusions.

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