suno_get_credits

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool retrieves account information, implying a read-only operation, but doesn't disclose any behavioral traits such as authentication requirements, rate limits, error handling, or what the response format might look like. For a tool with zero annotation coverage, this is a significant gap in transparency.

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, clear sentence: 'Get the current Suno account credits and subscription info.' It is front-loaded with the core purpose, has no unnecessary words, and efficiently conveys the essential information without waste, making it highly concise and well-structured.

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?

Given the tool's complexity (simple read operation) but lack of annotations and output schema, the description is incomplete. It doesn't explain what the return values include (e.g., credit balance, subscription details, format) or any behavioral aspects like error cases. For a tool with no structured data to supplement it, the description should provide more context to be fully helpful.

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 tool has 0 parameters, and the schema description coverage is 100%, meaning there are no parameters to document. The description doesn't need to add parameter semantics beyond what the schema provides. In such cases, the baseline score is 4, as there's no additional burden for parameter explanation.

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 tool's purpose: 'Get the current Suno account credits and subscription info.' It specifies the verb ('Get') and the resource ('Suno account credits and subscription info'), making it easy to understand what the tool does. However, it doesn't explicitly differentiate from sibling tools like 'suno_check_status' or 'suno_get_recent,' which might also retrieve account-related information, so it doesn't reach the highest score.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context for usage, or comparisons to sibling tools such as 'suno_check_status' or 'suno_get_recent.' This lack of explicit when-to-use or when-not-to-use information limits its helpfulness for an AI agent in selecting the correct tool.

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