Look up a Roblox game

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

With no annotations, the description carries the full burden. It explains what data is returned, mentions the thumbnail editability/read-only nuance, and clarifies input formats. It does not discuss errors or side effects, but as a read operation, this is acceptable.

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 concise and well-structured, consisting of two clear sentences with no redundant information. It efficiently covers all essential points.

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?

Given no output schema, the description sufficiently explains the return values (name, description, players, visits, likes, creator, and thumbnail editability). It also covers input options and the read-only implication, making it complete for the tool's purpose.

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 descriptions for both parameters are present and clear: 'game' accepts a link/place ID/universe ID, and 'isUniverseId' is set when the number is a universe ID. The description adds extra context that links are detected automatically, enhancing understanding beyond the schema.

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 clearly states the tool's function: retrieving Roblox game information (name, description, players, visits, likes, creator) from a game link, place ID, or universe ID. It distinguishes itself from siblings like search_roblox_games and get_thumbnails.

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 implies usage when needing game details and mentions important contextual notes (not requiring the game to be on this account, and its relevance to read-only project status). However, it does not explicitly state when to use this over alternatives, though the purpose is clear.

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