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

No annotations are provided, so the description must disclose all behavioral traits. The description mentions the return of task id, status, and URLs, implying an asynchronous pattern, but it does not explain the asynchronous behavior, polling, or whether the task is destructive. The schema hints at wait/timeout/polling, but the description does not connect these to the operational behavior, leaving the agent uninformed about side effects or execution flow.

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 sentence with no filler words. It is grammatically correct and front-loads the action and resource. However, given the tool's complexity, this brevity borders on under-specification rather than true conciseness. Yet, strictly by the dimension, it is efficient and free of extraneous content, earning a high score.

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 6 parameters, no output schema, and no annotations, the description must carry substantial weight. It tells the agent what the tool does and what it returns, but leaves out crucial context such as the purpose of 'inspire music' mode, how the audio URLs are used, the significance of the model versions, and any differences from the siblings. An agent cannot effectively decide or invoke this tool without further investigation.

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?

Schema description coverage is 67% (4 out of 6 parameters have descriptions, but timeout_ms and poll_interval_ms do not). Since coverage is not high (>80%), the description is expected to compensate, but it adds no parameter information at all. The only implicit reference is to audio_urls (as the required input), but it does not explain how they are used or their constraints (e.g., max 4 items). It falls short of the baseline 3 because the missing parameters remain undocumented.

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 a clear action ('Create a Suno task') and specific resource ('RunAPI' with 'inspire music' mode). It also mentions what it returns (task id, status, output URLs), which helps define its scope. However, it does not explicitly distinguish it from sibling tools that also generate music (e.g., text_to_music, cover_audio, create_mashup), so the differentiation is lacking.

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?

The description gives no guidance on when to use this tool versus alternatives. It does not state any prerequisites, exclusions, or when to prefer it over other music generation tools. The phrase 'inspire music' is ambiguous and not elaborated elsewhere. With 13 sibling tools in the same domain, this lack of contextual guidance is a major gap.

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