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 'Get' implies a read operation, but doesn't cover aspects like required permissions, rate limits, error conditions, or what the response contains. For a tool with no annotations, this leaves significant gaps in understanding its behavior.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded with the core action.

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 complexity (a retrieval tool with 2 required parameters), no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It lacks details on parameters, return values, and behavioral context, making it inadequate for effective use without external knowledge.

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 2 parameters with 0% description coverage, and the tool description doesn't explain what 'id' or 'applianceId' represent. Without this information, users must guess the meaning, such as whether 'id' refers to a cloud credentials record ID. The description fails to compensate for the low schema coverage.

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 action ('Get') and resource ('a specific helper appliance for a cloud credentials record'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'GetAllCredsHelperAppliancesWithFiltering' or 'CreateCloudCredsHelperAppliance', which would require mentioning it retrieves a single appliance by ID rather than listing or creating.

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 guidance is provided on when to use this tool versus alternatives. The description doesn't mention prerequisites, such as needing an existing cloud credentials record or helper appliance, or compare it to sibling tools like 'GetAllCredsHelperAppliancesWithFiltering' for broader queries.

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