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

With no annotations provided, the description carries full burden. It discloses only the 'one call per taskId' constraint, but fails to mention if the operation is destructive, what happens on repeated calls, authentication needs, or rate limits. The lack of behavioral context makes it risky for an AI agent.

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 two sentences, fully front-loaded with purpose in the first sentence and a key constraint in the second. No wasted words; every sentence adds value.

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 3 parameters and no output schema, the description provides core purpose and a constraint, but omits expected output type, file format, or error handling. Given the absence of output schema, more detail on return values would help completeness.

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 coverage is 100%, but the description adds important context: 'Auto-generated if omitted' for filename and a crucial warning about absolute directory paths for download_dir. 'One call per taskId' also relates to parameter usage, enhancing understanding beyond the schema.

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 verb 'generate' and the specific resource 'album cover art image for an existing Suno music track'. It distinguishes from sibling tools like 'generate_image' (general image generation) and 'create_music_video' (video). The constraint 'One call per taskId only' further clarifies the scope.

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 implies usage context (existing music track) and a constraint (one call per taskId), but does not explicitly state when to use this tool over alternatives like 'generate_image' or what prerequisites are needed. There is no guidance on when not to use it.

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