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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds meaningful behavior: prices are in ZAR per day, the page URL to book is returned, and date filtering has availability semantics rather than plain date matching. It does not describe pagination or result-ordering behavior.

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?

Three tight sentences, front-loaded with purpose, then filters, then return values. No redundancy and every clause carries information.

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, the description correctly supplies return-value info (ZAR/day prices and booking URL), and it covers the key filters and the dependency on list_categories. Nothing essential for a correct invocation is missing.

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 100%, so the baseline is 3; the description adds real meaning by defining start_date/end_date as an availability filter and pointing category at list_categories slugs. It omits any mention of query and limit, so it does not fully cover all six parameters.

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 resource (production gear) with concrete scope (camera, lens, lighting, sound), which cleanly separates it from siblings like search_creators and get_gear. An agent can tell what this tool returns without opening the schema.

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?

Explains how the optional filters combine and explicitly routes the agent to list_categories for valid category slugs, plus clarifies that date filters keep only items free on those dates. It stops short of stating when NOT to use it or naming alternatives like get_gear/search_creators.

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