get_timestamped_lyrics

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

No annotations are provided, so the description needed to cover side effects, auth/cost expectations, and output semantics; it only discloses that the operation is synchronous and returns the operation result. It does not mention potential credit usage, permission requirements, or that the result is likely a raw API payload rather than parsed lyrics.

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?

Two short sentences with no fluff; the synchronous behavior and returned result are front-loaded. The phrase 'Run a synchronous Suno operation' is slightly generic, but overall the description is efficient.

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 no output schema and no annotations, this is underspecified: it lacks when-to-use guidance, expected return shape beyond 'operation result', and any behavioral caveats such as cost or latency. The schema covers inputs well, but overall call context is 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?

All parameters are already documented in the schema (100% coverage), so the baseline for this dimension is 3. The description adds no param-level detail, but it does not need to given the schema's thorough descriptions of source_audio_id and source_task_id.

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 identifies the target operation (timestamped lyrics via Suno on RunAPI) and notes it returns the operation result, so an agent can see this is a retrieval-style operation distinct from generate_lyrics or get_task. However, the verb 'Run' is generic and the boundary of what 'timestamped lyrics' means vs other Suno operations is only implicit.

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 explicit guidance is given on when to call this tool rather than generate_lyrics or get_task. The name and parenthetical imply the use case, but the description never states a selection rule or alternatives, leaving an agent to infer.

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