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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds useful output context (ownership, members, verification, ranking, concurrent players, visits, likes) but does not cover auth needs, rate limits, or response structure, so it remains a moderate addition over 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?

The description is a single dense sentence with a colon-delimited list of return fields. It front-loads the resource but is overstuffed and grammatically awkward, making it harder to parse than necessary.

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 tool with no output schema, the description helpfully lists many returned fields, but it does not resolve the ambiguity of having zero required parameters. It says lookup happens by game or name yet does not state what occurs if neither or both are supplied, leaving a meaningful behavioral gap.

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 input schema already documents both optional parameters. The description reinforces the two lookup modes ('by one of their games or by name') but adds no syntax, format, or precedence rules beyond what the schema provides.

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 identifies the resource precisely: a developer (Roblox group or person) and the games they make, looked up by game or name. It is clear what the tool retrieves, though it uses a noun phrase rather than an explicit verb and does not explicitly differentiate itself from siblings like game or search.

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 explains the two input modes ('by one of their games or by name') but gives no when-to-use context, no alternatives, and no exclusions. An agent gets no guidance on when this tool is preferable to sibling tools such as game or search.

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