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

No annotations are present, so the description must disclose behavioral traits. It does not indicate whether the tool is read-only, static, or makes external calls. It simply describes the concept of languages without any behavioral information, leaving the agent to assume it is a safe, simple listing operation.

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 redundancy. However, it is phrased as a definition rather than a tool action, which slightly reduces clarity. Still, it is appropriately brief and front-loaded.

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?

There is no output schema, so the description should explain what the tool returns. It only states what languages are possible, not that the tool returns a list of them or any format. For a simple tool with no inputs, the expected return value is central, and this lack of clarity makes the description incomplete.

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?

With zero parameters and high schema coverage (100% of an empty schema), the baseline is 4. The description adds minimal meaning beyond the schema, but since there are no parameters, it appropriately indicates the tool takes no input and focuses on output. It does not need to explain parameters.

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 states the tool concerns languages for clinical notes, but it does not explicitly say the tool lists or retrieves them—the name implies it. It is distinct from sibling tools which cover pricing, features, positioning, comparison, and compliance, but the purpose is stated as a fact rather than an action, making it somewhat vague.

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 is provided on when to use this tool versus alternatives. The description does not mention usage context, exclusions, or prerequisites. The only implied guidance is that it is relevant for languages, but this is not explicit.

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