get_exam_otp

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

No annotations are provided, so the description must bear the full burden of disclosing behaviors. It fails to mention whether the OTP is consumed, expires, or any side effects. It also doesn't state if authentication or session is required.

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 extremely concise at five words, but it sacrifices informativeness. While not verbose, it doesn't earn its place by providing enough detail for correct invocation.

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?

With no output schema, the description should explain how the OTP is returned (e.g., as a string, in a response field) and for what purpose. It is incomplete and leaves critical gaps about the tool's behavior.

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?

There are no parameters, and schema coverage is 100% (empty schema). The description adds no meaning about implicit inputs (e.g., current user/session), which would be valuable. Baseline 4 reduced due to lack of context on what the tool relies on.

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 uses a specific verb ('Get') and resource ('one-time password for exam'), clearly indicating the tool's purpose. However, it does not distinguish from siblings like 'verify_authentication' or 'interactive_login', which might be related.

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, nor any prerequisites (e.g., having an active exam session or being authenticated). The agent is left to infer context.

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