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

No annotations provided, so the description carries the full burden. It reveals a key behavioral trait: these are deterministic non-LLM opponents. However, it omits whether the list is paginated, cacheable, or has rate limits. Some disclosure, but gaps remain for a read-only listing tool.

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 short, front-loaded sentences that earn their place: the first states the resource, the second clarifies the nature of the entities. No filler.

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 parameterless read-only tool, the description is adequate but incomplete without annotations or output schema. It doesn't cover return structure or practical usage. Missing some context an agent might need, but core intent is clear.

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?

Zero parameters, so baseline is 4. No parameter semantics are needed, and the description adds meaning about what is listed.

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?

Clear verb 'List' plus specific resource 'predetermined deterministic Chess Hall computer opponents'. The second sentence distinguishes these bots from LLM agents, adding helpful scope. The 'chess_list_bots' name is somewhat redundant with the description, but the tool is easy to understand.

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?

No guidance on when to call this tool versus alternatives. An agent wouldn't know when to list bots versus creating a match or listing scenarios. The description explains what the bots are, not when to use this tool.

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