get_database_cluster_credentials

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

No annotations are provided, so the description must fully disclose behavior. It states 'Get', implying a read-only operation, but does not mention potential side effects, required permissions, or sensitivity of credentials. This is insufficient for an agent to understand behavioral traits.

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 very short at one sentence, which is concise but at the cost of completeness. It is front-loaded with the core action, but lacks necessary details, making it minimally acceptable.

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 lack of annotations, output schema, and parameter descriptions, the description is insufficient for an agent to use the tool correctly. It does not explain what the returned credentials look like, how to interpret the parameters, or any contextual constraints.

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 input schema has two parameters ('name' and 'namespace') with 0% description coverage, meaning the schema provides no descriptions. The tool description only mentions 'a specific database cluster' without explaining how these parameters identify the cluster or what values are expected. No additional meaning is added beyond the parameter titles.

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 uses the verb 'Get' and specifies the resource 'credentials for a specific database cluster', making the tool's purpose clear. However, it does not differentiate from sibling tools like 'get_database_cluster', which might retrieve cluster metadata, and fails to clarify what exactly 'credentials' entails (e.g., connection string, username/password).

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 usage guidelines are provided. The description does not indicate when to use this tool versus alternatives like 'get_database_cluster' or 'list_database_clusters', nor does it specify prerequisites or typical use cases.

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