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

No annotations are provided, so the description carries the full burden. It states it retrieves a record but doesn't disclose behavioral traits like whether it's a read-only operation, error handling for invalid IDs, response format, or any rate limits. This leaves significant gaps for a tool that likely involves sensitive credentials.

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 is front-loaded and earns its place by clearly conveying the core functionality.

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 (retrieving sensitive credentials), lack of annotations, no output schema, and low schema coverage, the description is insufficient. It doesn't address security implications, response structure, or error conditions, making it incomplete for safe and effective use.

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 schema has 0% description coverage, but the description adds meaning by specifying that the 'id' parameter is for retrieving a specific cloud credentials record. However, it doesn't elaborate on the ID format (e.g., UUID, string pattern) or provide examples, which is a missed opportunity given 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 cloud credentials record by ID'), making the purpose unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'GetAllCloudCreds' or 'GetCloudCredsHelperAppliance', which would require a 5.

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 like 'GetAllCloudCreds' for listing all records or 'BrowseCloudEntity' for browsing. It also lacks prerequisites such as authentication requirements or ID format expectations.

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