C2.9/5.0

Behavior2/5

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

With no annotations, the description must disclose behavioral traits itself. It only mentions the return values but does not disclose that this is likely an asynchronous task creation with polling/wait options, that it incurs cost, or that it requires authentication. The existence of wait, timeout_ms, poll_interval_ms, and callback_url parameters implies asynchronous behavior, but the description is silent on it.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that quickly states the action and the return type. It is short and front-loaded with the core purpose, with no wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a complex tool with 18 parameters, no annotations, and no output schema, the description is inadequate. It mentions the return values but does not explain how to use the task id, whether to wait, what statuses mean, or any usage constraints. An agent would need to rely on the schema, which still leaves gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already describes the parameters with 89% coverage. The description adds no parameter-specific meaning beyond the name 'cover audio', which is already apparent from the tool name. Since schema coverage is high, the baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool creates a Suno task for covering audio on RunAPI and lists the return values. It uses a specific verb ('Create') and resource ('Suno task'), and the 'cover audio' qualifier distinguishes it from many sibling tools, though it does not explicitly name alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided about when to use this tool versus alternatives like convert_audio or remaster_audio. There is no mention of prerequisites, context, or exclusion criteria, so an agent is left without direction on tool selection.

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