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. 'Add a new cloud credentials record' implies a write operation (creation), but it doesn't specify required permissions, whether this is idempotent, what happens on failure, or any rate limits. For a mutation 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, efficient sentence: 'Add a new cloud credentials record.' It's front-loaded with the core action and resource, with zero wasted words. This is appropriately concise for a tool with a straightforward purpose, though the brevity contributes to gaps in other dimensions.

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 mutation tool with nested parameters), lack of annotations, 0% schema description coverage, and no output schema, the description is incomplete. It doesn't address parameter details, behavioral traits, error handling, or output expectations. For a tool that creates cloud credentials—likely involving sensitive data and permissions—this minimal description is inadequate.

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 1 parameter ('body') with 0% description coverage and no details on its structure. The tool description adds no information about parameters—it doesn't mention what fields 'body' should contain, example values, or format. With low schema coverage, the description fails to compensate, leaving parameters largely undocumented.

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 'Add a new cloud credentials record' clearly states the action (add) and resource (cloud credentials record), which is specific enough to understand the basic function. However, it doesn't distinguish this tool from sibling tools like 'CreateCreds' or 'UpdateCloudCreds', leaving ambiguity about when to use each. The purpose is clear but lacks sibling differentiation.

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. With sibling tools like 'CreateCreds' (likely for general credentials), 'UpdateCloudCreds' (for updates), and 'DeleteCloudCreds' (for removal), there's no indication of prerequisites, constraints, or comparative use cases. This leaves the agent without direction on tool selection.

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