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

With no annotations provided, the description carries the full disclosure burden. It compensates partially by listing the specific data fields returned, implicitly indicating this is a metadata retrieval operation. However, it lacks explicit safety assertions (read-only nature), rate limit warnings, or authentication requirements.

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?

Single efficient sentence front-loaded with the action ('Get API key information') followed by a colon-delimited list of return fields. Every word provides value; 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 zero-parameter information retrieval tool without output schema, the description adequately compensates by enumerating the expected return fields (credits, status, models, etc.). Sufficient for tool selection, though auth context could strengthen it.

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?

Input schema contains zero parameters, establishing a baseline score of 4 per rubric rules. No parameter description compensation is required.

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?

Description uses specific verb 'Get' with resource 'API key information' and enumerates the returned fields (description, creation date, credits, etc.). It implicitly clarifies that 'key' refers to API credentials rather than musical keys (relevant given audio-processing siblings), but does not explicitly differentiate from sibling tools.

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?

Description provides no guidance on when to invoke this tool versus others, nor prerequisites like authentication state. It simply states what the tool retrieves without contextual usage advice.

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