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

With no annotations provided, the description carries the burden of behavioral disclosure. It usefully states the return payload (task id, status, result), but does not disclose asynchronous behavior, required authentication, or polling semantics. This is partial disclosure but leaves significant context to the schema.

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 consists of two short sentences, front-loaded with the action and resource. Every word contributes: it states the operation, context (Suno/RunAPI), and return structure, with no redundancy.

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?

For a tool with 5 parameters, no annotations, and no output schema, the description gives the basic purpose and return structure but lacks important context about async polling, parameter semantics, and usage boundaries. It is adequate for a high-level understanding but not fully complete for an agent to invoke correctly without inferring from schema.

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 description does not mention any parameters or their roles. With 60% schema coverage, two parameters (timeout_ms, poll_interval_ms) are undocumented in both schema and description, and the description adds no semantic meaning to the prompt, wait, or callback_url 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 clearly states the action ('Create a Suno task') and the specific function ('generate lyrics'), along with the return payload (task id, status, result). It distinguishes from siblings like text_to_music or blend_lyrics by focusing on lyric generation, though it doesn't explicitly name them.

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?

Usage is implied by the phrase 'generate lyrics' but there is no explicit guidance on when to use this tool vs alternatives, nor any exclusions or prerequisites. The description does not mention when to prefer this over text_to_music or other Suno-related tools.

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