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

With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a mutation ('Change'), but doesn't specify if this requires admin permissions, is reversible, has side effects (e.g., downtime), or involves rate limits. This is inadequate for a tool that modifies 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 with no wasted words, making it easy to parse. It's appropriately sized for the tool's apparent complexity, though it lacks depth.

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 tool's complexity (mutating credentials with 2 parameters, nested objects, no output schema, and no annotations), the description is incomplete. It doesn't cover parameter meanings, behavioral traits, or usage context, making it insufficient for safe and effective tool invocation.

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?

Schema description coverage is 0%, so the description must compensate but fails to do so. It doesn't explain the 'id' (e.g., identifier of the cloud credentials record) or 'body' (e.g., new certificate details), leaving both parameters undocumented and their semantics unclear.

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 states the action ('Change') and the target ('certificate for a cloud credentials record'), which is clear but vague. It doesn't specify what type of certificate (e.g., SSL/TLS, authentication) or how the change affects the system, and it doesn't differentiate from sibling tools like 'ChangeCloudCredsSecretKey' or 'ChangeKMServerCertificate' that handle similar credential modifications.

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 lacks context such as prerequisites (e.g., existing cloud credentials), exclusions, or comparisons to sibling tools like 'UpdateCloudCreds', leaving the agent with no usage direction.

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