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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety and reach profile is covered. The description adds the pagination behavior ('continue result pages with the returned page token'), a useful non-obvious trait, but says nothing about result counts, limits, or ordering, so it goes only modestly beyond the annotations.

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 tight sentences with the core purpose front-loaded and the routing guidance second. No filler; every clause earns its place.

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 an output schema present (no need to explain return values) and annotations covering safety, the description only needs to establish scope, routing, and pagination — all of which it does. Minor gaps remain (no mention of result count or default behavior), keeping it just short of fully complete.

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 100%, so both q and page_token are already documented in the schema. The description restates the query intent ('game experiences') and references the returned page token but adds no format, syntax, or constraint detail beyond what the schema provides; baseline 3 is correct.

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?

Specific verb ('Search') plus a precisely scoped resource ('public Roblox game experiences'), with the pagination facet ('continue result pages') included. It explicitly distinguishes itself from siblings roblox_game (single-experience details) and roblox_rankings (charts), so an agent can route without opening any 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?

Names two alternative tools and the exact condition that selects each ('Use roblox_game for one experience's details or roblox_rankings for charts'). This is explicit when-to-use-this-vs-alternatives guidance rather than an implied hint.

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