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

No annotations are present, so the description must carry the full burden. It states only 'Evaluate', which implies a non-mutating analysis, but does not disclose any side effects, permissions, or operational constraints. The description adds no information beyond the action itself.

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 concise sentence with no filler. It front-loads the verb and resource, making the tool's purpose immediately clear.

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 that the output schema exists, return values are covered elsewhere, but the description does not explain the parameter, any usage constraints, or any behavioral traits. For an otherwise simple tool, the description is thin and leaves an agent guessing about the benchmark_filter values and the intended use cases.

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?

The sole parameter 'benchmark_filter' is not described anywhere in the description, and the schema provides no description (0% coverage). The name suggests a filter, but the accepted values, default behavior, and format are left entirely unexplained. The description does not compensate for this missing schema context.

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 names a specific verb ('Evaluate') and a specific resource ('broad generalization across spatial commons, multi-agent arenas, and sequential causal puzzles'). It delineates the scope of the tool clearly, though it does not explicitly contrast it with sibling tools such as evaluate_cooperation.

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?

There is no guidance on when to use this tool versus alternatives. The description simply states what it does, leaving the agent to infer context. No prerequisites or exclusions are mentioned.

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